Before we begin with the list, we’ll introduce you to how dual SIM technology works, market demands, things you can do using it, etc. Not Interested? Jump to the list.

With the modern lifestyle where people have to expand their network, DUAL sim smartphones have become an inevitable part of our lives. The phones tend to come with an additional SIM card slot allowing users to manage the business and personal calls from a single device.

Although the demand for a dual SIM phone isn’t that high in the US like the UK and other parts of the world, this year saw a rise in demand, and experts think it would boom in the coming year, i.e. 2022. Another reason for the rise in demand is because the network operator that provides good coverage at their home doesn’t provide it at their workplace or vice versa.

Almost most of the popular smartphones come with dual SIM. Gone are the days when you had to carry 2 phones to keep your business and personal networks separate. This is one of the biggest advantages of having a dual sim phone. You can assign one number for work and another for friends and family (helps a lot with work-life balance.)

There used to be times when telephonic calls used to cost huge when people only had landlines and cordless phones at their places. Now, it’s not calling that has gotten cheaper, but it also happens that some carriers such as AT&T, Verizon and Sprint offer cheaper data plans, better-calling plans.

Samsung Galaxy S20 is probably the best overall dual SIM smartphone you can purchase today. One of the most popular devices from the S20 lineup, this device packs powerful hardware and improved software from Samsung to provide the best-in-class smartphone experience.

The United States version of Samsung Galaxy S20 comes with Qualcomm Snapdragon 865, a flagship chipset with 5G support and blazing speeds. This octa-core processor can keep up with heavy multitasking and intense gaming at the same time. Its Adreno 650 GPU does a commendable job of providing crystal-clear graphics as well.

With 12GB of RAM, this Samsung flagship can compete with even entry-level laptops. This extra RAM comes in handy when you want to multitask like anything or while using Samsung Dex. Similarly, 128GB of storage can store all your 8K footages without needing an SD card. As of now, this smartphone runs Android 10 with the One UI 2 on top. Of course, you can expect a quick update to Android 11 whenever it’s launched.

Samsung has packed a 6.2-inch QHD AMOLED display on this device. The panel has a 120Hz refresh rate when on FHD resolution but reduces to 60Hz when you shift to QHD. On top of its 1440 x 3200 resolution, the panel is protected by Corning Gorilla Glass 6 as well.

Following the footsteps of other flagships in the market, S20 also comes with a triple-camera setup. You have a 12MP main camera that creates stunning images, accompanied by 12MP wide-angle and a 64MP telephoto lens. The main camera lets you record 8K video at 24fps and 4K video at 60/30fps. There is also a single-lens 10MP camera with 4K recording.

This version of the S20 has a weight of 163g and a thickness of 0.31 inches. While these numbers don’t make the device the slimmest in the market, you can enjoy the classy weight at times. Coming to connectivity, it brings 5G support along with Wi-Fi 6, NFC, GPS, and Bluetooth 5.0. Samsung has also included an ultrasonic, under-display fingerprint scanner on the device.

The device is equipped with a 4000mAh non-removable battery that comes with 25W fast charging support. In addition, you get 15W wireless charging and 9W reverse wireless charging. This means you can be up and running in just a few minutes.

By the way, if you are looking for bigger screens and improved battery capacity, you can always check out Galaxy S20+ and S20 Ultra, both of which come with extended 5G compatibility.

Pros
  • Flagship-grade processor
  • Excellent QHD Display
  • 5G and LTE Support
  • Triple Camera with 8K Video
  • All-day battery
Cons
  • Bulky design
  • RAM: 12GB
  • Processor: Snapdragon 865
  • Display: 6.55-inch AMOLED with 120Hz
  • Front Camera: 16MP Wide
  • Rear Camera: 48MP Main + 16MP Ultra-Wide + 5MP Macro + 2MP Mono

Despite the OnePlus 8T being termed as a mid-range smartphone, owing to the cost-efficient price tag, it continues to be the best flagship killer in the market. While the potent processor, gamer-friendly smartphone display, and massive battery continue to hold the fort for this gadget, we were more impressed with the excellent performances and the nifty user-friendly specifications.

When tested hands-on, we felt that that the Qualcomm Snapdragon 865 processor readily justifies the price tag and even exceeds expectations. Despite flaunting the 7nm chipset architecture, the featured SoC is best known for the octa-core processing setup, with the single Kryo 585 core capable of reaching a maximum speed of up to 2.84GHz. Clubbed with the Adreno 650 GPU, the processing module is more than capable of handling any volume of multitasking workload.

As far as the smartphone memory is concerned, the OnePlus 8T comes in two variants, with one featuring 8GB RAM and the other housing 12GB of the same. However, we are currently using the latter and experiencing buttery smooth performances, despite having every application open.

Storage-wise, the 12GB version offers 256GB of capacity, which is insanely high for a smartphone. We were impressed with the UFS 3.1 storage technology, which ensures that the OxygenOS 11 set atop the Android 11 platform, boots up in almost no time.

Coming to the build quality, the OnePlus 8T flaunts an aluminum frame and glass-centric undertones. Moreover, as compared to the preceding versions, the OEM seems to have improved the overall grip associated with the smartphone. Sitting atop the durable frame is the 6.55-inch Fluid AMOLED panel. While the smartphone screen flaunts the HDR10+ enhancement to achieve the highest possible levels of color accuracy, the 120Hz refresh is a reliable asset to smartphone gamers.

As far as the screen resolution is concerned, you get access to 1080 x 2400 pixels. Moreover, OnePlus also brings the Always-on display enhancement into the scheme of things whilst protecting the panel with Gorilla Glass 5 support. Moreover, this gadget weighs close to 188 grams and also showcases a glass-layered rear panel, strengthened considerably by the Gorilla Glass 5 technology.

The camera modules deserve a special mention with the rear unit comprising four separate shooters to offer the best possible experience. While the 48MP primary camera is best known for the exceptional f/1.7 aperture, precisely to support low-light imagery, it is perfectly paired by the 16MP wide-angle shooter.

Moreover, you also get access to a 5MP macro lens for capturing smaller objects followed by a 2MP mono, depth-sensing lens for added coverage, dual-LED flash, and the panorama mode. OnePlus 8T doesn’t cut corners when the front shooter is concerned. You still get access to a 16MP selfie module with a wide-angle projection.

Coming to the design-centric perks, this smartphone flaunts a stealth fingerprint scanner followed by integrated stereo speakers. Much like the newest lineup of iPhones, even this smartphone does away with the 3.5mm audio jack. Connectivity-wise, the OnePlus 8T offers Wi-Fi 6 support with 5G compatibility, Bluetooth LE, NFC, and USB OTG compatibility. Besides, this gadget comes with dual-SIM compatibility, supporting Nano-SIM cards and the dual standby mode.

The unit we are reviewing features a massive 4500mAh battery module, which is bolstered further by the fast charging technology, via the 65W adapter. When it comes to the nomenclature, the OnePlus tags the same as the Warp Charging technology. However, OnePlus doesn’t opt for a conventional battery module and features two 2250mAh units, paired as one.

Overall, the OnePlus 8T is arguably one of the best smartphones in the retail circuit, if you are looking for a DSLR-grade smartphone camera and a brilliant display to view content.

Pros
  • Excellent processor with 8 Kryo cores
  • A sizable and ultrafast storage module
  • Glass panel strengthened by Gorilla Glass 5 enhancement
  • 120Hz screen refresh rate
  • Wrap charging support 
  • 4-element rear shooter
Cons
  • No water resistance rating
  • Doesn’t support wireless charging
  • RAM: 4GB
  • Processor: Apple A14 Bionic
  • Display: 6.1-inch True-Tone with 60Hz
  • Front Camera: 12MP Wide
  • Rear Camera: 12MP Main + 12MP Ultra-Wide
  • Battery: 2815mAh (with 20W fast charging)

While we reviewed quite a few dual-SIM smartphones, none were as striking and efficient as the new Apple iPhone 12. Best known for an improved design, class-leading cameras, and a strengthened screen, this gadget certainly deserves all the accolades that are pouring in from the smartphone enthusiasts.

While the iPhone 12-series comprises four variants, including the Mini, Pro, Pro Max, and the vanilla iPhone, the latter actually strikes the perfect balance between performance and affordability. As far as the processor is concerned, you get to experience the brilliance of the A14 Bionic chip from Apple, which achieves the highest possible levels of hardware-software cohesion.

As it is a 5nm chipset with Firestorm six Firestorm cores to rely on, it can still reach the highest possible clock speed of up to 3.1GHz for a maximum of two cores. Moreover, the Apple GPU with a quad-core setup makes an appearance; lending assistance to the hexa-core SoC. Coming to the RAM, iPhone 12 offers 4GB of the same, which might seem slightly overwhelming as compared to the other flagships.

However, you must understand that the 4GB exhibited by iPhone 12 is at par with the 12GB RAM featured by some of the other similarly priced gadgets. Storage-wise, there are three models to rely on, with the reviewed one featuring 128GB of ultra-fast storage space. However, it is the NVMe-compatibility that adds heft and additional features to the existing storage setup. As far as the operating system is concerned, Apple offers iOS 14.1, straight out of the closet.

Coming to the display, you get access to a 6.1-inch screen, which exhibits an overall resolution of 1170 x 2532 pixels. The Super Retina screen also flaunts the XDR OLED technology followed by the new and innovative ceramic glass that is highly scratch resistant. Other display-centric attributes include the True-tone technology, Dolby Vision support, and the widest possible color gamut for viewing the brilliant clicked images.

Now that we have mentioned the clicks, the brilliant dual camera setup deserves a special mention. At the rear, you have the 12MP primary camera with an f/1.6 aperture. In addition to that, you also get a secondary 12MP shooter with ultra-wide, image capturing capabilities. Other relevant specs include dual-LED flash, HDR, Optical Image Stabilization, and video capturing support at 1080p and even 4K presets.

As far as the design accents are concerned, you get the matte aluminum of the iPhone 12 followed by a bold layout and squared-off device edges. In addition to that Apple also promises drop protection and even lives up to the same, as per our drop tests. Not just that, the ceramic shield protecting the screen is further complemented by the Gorilla Glass support and the much-anticipated IP68 certification, offering water and dust resistance to the iPhone 12.

When it comes to connectivity, the Apple iPhone 12 features dual-SIM support, either as the Nano-SIM setup or eSIM enhancement. Other relevant specs include 5G support, NFC, Lightning port, and support for Apple Pay. Coming to the battery, the iPhone 12 houses the 2815mAh module, which is characterized by fast charging and wireless charging support. Coming to autonomy, this device is capable of churning out close to 17 hours on runtime.

At 164g, the iPhone 12 is one of the best devices to be launched by Apple. While there are many dual-SIM smartphones to rely on, the iPhone 12 is certainly the top-rated and most premium option to invest in.

Pros
  • Premium aesthetics
  • Brilliant camera setup with reliance on autofocus
  • Fastest dual-SIM phone on the list
  • Water and dust resistance
  • Comes with 5G support
Cons
  • Pricey
  • Screen refresh rate is pretty basic
  • RAM & Storage: 8GB + 128GB
  • Processor: Snapdragon 855+
  • Display: 6.59-inch AMOLED with 120Hz
  • Front Camera: 24MP
  • Rear Camera: 48MP Main + 13MP Ultra-Wide
  • Battery: 6000mAh (with 30W Fast Charging)

A dual SIM smartphone is the perfect choice for hardcore gamers who need high-speed networks no matter where they go. ASUS ROG Phone 2 becomes such an impressive choice by bringing a flagship-grade processor and a super-huge battery into the package.

To enable the best performance with even the most graphics-intensive games, ASUS has used a Qualcomm Snapdragon 855+ processor on this device. This octa-core chip delivers competitive performance, also thanks to the Adreno 640 GPU inside.

This version of the ROG Phone 2 comes with 8GB of RAM and 128GB of storage. 8GB is enough to manage even the toughest games because the system manages resources very well in the gaming mode. There are also higher storage versions you can buy, by the way. The device runs on Android 9 with ROG UI on top, but you can always shift to a minimal-ish Android UI.

Because it’s supposed to assist games in the visual impact, the ROG Phone 2 comes with a 6.59-inch Full HD+ AMOLED display. This panel has a resolution of 1080 x 2340 and a refresh rate of 120Hz. You also get support for HDR10 and the protection from Corning Gorilla Glass 6.

ASUS has not made this smartphone to be an excellent camera device. However, you can still depend on the dual-camera setup – with 48MP primary sensor and 13MP Ultra-Wide sensor – for standard photos and 4K video. There is also a 24MP single sensor on the front, and it supports 1080p video recording and decent selfies.

Considering the weight of 240g and thickness of 0.37 inches, this ROG smartphone is bigger. ASUS has used this extra space to accommodate a bigger battery and cooling technologies. On the connectivity side, you get GPS, NFC, Wi-Fi, and Bluetooth 5, which can extend the gaming capabilities. It does not come with 5G connectivity.

Because it’s made for hardcore gamers, the 6000mAh battery on the device is a perfect choice, indeed. It comes with 30W Fast Charging, which means you don’t have to wait for hours to charge the phone fully. And if you are not gaming continuously, you can expect the device to last for more than a day. You don’t get Qi wireless charging in the package, though.

Despite all the excellent gaming-centric features, ASUS ROG Phone 2 doesn’t break your wallet. You can use that extra money to get some gaming accessories as well.

Pros
  • Gaming-grade performance
  • Long-lasting battery
  • 120Hz display
  • Impressive connectivity
  • Budget-friendly
Cons
  • Semi-decent camera
  • RAM: 8GB
  • Processor: Exynos 990
  • Display: 6.7-inch sAMOLED+ with 60Hz
  • Front Camera: 10MP Wide
  • Rear Camera: 12MP Main + 64MP Telephoto + 12MP Ultra-Wide
  • Battery: 4300mAH (with 25W fast charging)

If you are in the market for a tablet-like dual-SIM smartphone, you can blindly place your bets on the Samsung Galaxy Note 20. However, despite flaunting a 6.7-inch screen and stylus support, the gadget still weighs significantly less than 200 grams. 

Coming to the processing setup, Samsung features the ever-reliable Exynos 990 GPU, for supplies outside of the United States. The octa-core Exynos CPU is further complemented by the ultra-fast Mongoose cores, with the highest speeds reaching close to 2.73GHz. Besides, the Mali-G77 MP11 graphics processing unit lends adequate support to the concerned mobile SoC. 

As far as the RAM support is concerned, 8GB of system memory is more than adequate for a smartphone as big as the Galaxy Note 20. However, we were most impressed with the 256GB of storage space, best known for the UFS 3.0 technology. Coming to the operating system, the Note 20 offers Android 10 straight out of the box, with the One UI 3.0, riding atop the same. 

The Galaxy Note 20 also flaunts a massive, 6.7-inch screen, as mentioned previously. However, what impressed us the most is the FHD+ resolution, equating to 1080 x 2040 pixels. Moreover, the always-on panel is further protected by the Gorilla Glass 5 support. The camera setup, on the other hand, is nothing less than revolutionary, as Samsung brings forth a triple front shooter to make image capturing easier for the customers.

When it comes to the rear setup, you get access to a 12MP primary camera with an f/1.8 aperture. Besides, Samsung also makes way for the 64MP telephoto lens followed by yet another 12MP ultra-wide lens. Not just that, the rear setup is also bolstered by additional perks like auto-HDR, LED flash, and the panorama mode. Samsung also makes room for a 10MP selfie shooter with PDAF compatibility.

In terms of layout, the Samsung Galaxy Note 20 equates to a durable slab of glass, with the heft reaching up to 192 grams. However, the design lines are cleaner than usual and the smartphone also boasts of improved stylus compatibility. Not just that, Samsung sweetens the pot further for the customers with IP68 certification, boasting of water and dust compatibility. 

As far as connectivity is concerned, the dual-SIM support is closely followed by 5G compatibility, Wi-Fi 6 support, USB OTG, Bluetooth LE, and other relevant standards. The 4300mAh battery, on the other hand, is worth mentioning, courtesy of the 24-hour runtime, fast charging support, wireless charging enhancement, and the reverse charging feature with the gadget working as a power bank. 

Overall, the Galaxy Note 20 scales beyond any competition when it comes to dual-SIM smartphones, courtesy of the sizable screen, excellent camera, and relevant user-friendly traits.

Pros
  • Fantastic display
  • Excellent battery life
  • S-pen works like a charm
  • Brilliant shooter with added versatility
  • The adaptive refresh rate is a decent inclusion
Cons
  • The camera bump is intimidating
  • Not the best charging speed
  • RAM & Storage: 6GB + 128GB
  • Processor: Snapdragon 855
  • Display: 6.5-inch 4K OLED with 60Hz
  • Front Camera: 8MP Wide
  • Rear Camera: 12MP Main + 12MP Telephoto + 12MP Ultra-Wide
  • Battery: 3330mAh (with 18W Fast Charging)

Smartphones from Sony are not the most popular ones right now; we agree. However, if you are looking for some specific features like CinemaWide display and highest-quality sound, Sony has a few dual-SIM devices you can check out today. And Sony Xperia 1 seems to be the best option right now.

Following the style of many flagship smartphones we have covered, Sony Xperia 1 also uses the Qualcomm Snapdragon 855. It has the Adreno 640 GPU as well. Together, this Xperia flagship provides seamless speed and performance when it comes to media consumption and even gaming.

Sony has packed 6GB of RAM in this device, which seems just enough according to today’s smartphone styles and standards. However, thanks to the lightweight Xperia skin, there is no impact on performance. You also get the standard 128GB of built-in storage with expansion capabilities. By the way, the device comes with a hybrid SIM slot, meaning that you cannot use the dual SIM and SD card at the same time.

Xperia 1 is known for its magnificent display, and it’s exceptional. You get a 6.5-inch 4K OLED panel with the CinemaWide design and 21:9 aspect ratio. In addition to the 1644 x 3840 resolution, you get HDR support and X-Reality Engine as well.

This creator-friendly device comes with a triple-camera setup on the back. It consists of a 12MP primary lens, 12MP telephoto lens, and a 12MP ultra-wide lens. Using the technology from Sony Alpha products, you can record high-quality videos at movie-like quality as well. Although the sensor caps maximum video resolution at 4K, you will have impressive footages for sure. On the front, you have a standard 8MP wide sensor.

By housing the ultrawide display itself, the Xperia 1 becomes a large device, of course. It is 0.32 inches thick and weighs 178g. However, Sony has included IP68 and Corning Gorilla Glass protection. On the connectivity side, you get Wi-Fi, Bluetooth, NFC, GPS, and 4G LTE. You can also use DLNA technology to connect with compatible smart TVs.

Compared to the severe hardware and software features inside, the 3330mAh battery seems insufficient to handle the pressure. While it does not have wireless charging of any sort, Sony has added 18W Fast Charging to the package. The device ships with a high-speed charger, which is a good thing. You also get a US warranty for this smartphone.

Despite a few shortcomings, Xperia 1 is a superb choice if you are into professional photography/video. By the way, if you like this package, you may also want to check out Sony Xperia 5.

Pros
  • Movie-quality camera
  • 21:9 CinemaWide Display
  • Triple-Camera System
  • IP68 Protection
  • Dolby Atmos
Cons
  • Only a 60Hz screen
  • Low-capacity battery
  • RAM & Storage: 8GB + 256GB
  • Processor: Snapdragon 855+
  • Display: 6.67-inch OLED with 90Hz
  • Front Camera: 16MP Pop-up
  • Rear Camera: 48MP Main + 16MP Ultra-Wide + 8MP Telephoto
  • Battery: 4085mAh (with 30W Fast Charging)

If you don’t want to get the OnePlus flagship we listed up top, the OnePlus 7T Pro is your next best shot. It’s also one of the best camera phones you can grab under $650. You also get several OnePlus-exclusive features in the package.

Powering this performance-friendly smartphone is a Qualcomm Snapdragon 855+, which has an octa-core CPU and an Adreno 640 GPU inside. Both these elements make the device capable of multitasking very well. You can also use it for some online multiplayer games like PUBG.

The device, being a Pro version of the 7T, comes with 8GB of RAM. This is more than sufficient to take care of heavy social media usage or high-graphics games. Similarly, 256GB of storage becomes a better choice, as you cannot upgrade the storage. As for the OS, it runs the latest version of OxygenOS, which is an improved version of Android 10. The OS offers a minimalistic Android experience without a lack of features.

Compared to its standard version, the 6.67-inch QHD+ OLED display on this device looks very good. It has a superb resolution of 1440 x 3120, as well as a Refresh Rate of 90Hz. The pop-up camera mechanism does a great job of enabling an authentic full-screen experience as well.

As we said, the camera is one of the best things about this device. On the back, you can find a trio of sensors – a 48MP Primary sensor, an 8MP Telephoto sensor, and a 16MP Ultra-Wide sensor. With its comprehensive setup, OnePlus 7T Pro can take a wide variety of shots. You also get some cool features like Nightscape and Portrait Mode. On the front, we have a 16MP sensor that is powered by a motorized pop-up.

OnePlus 7T Pro also belongs to the big side of smartphones right now. It not only weighs 206g but also has a thickness of 0.35 inches. This is actually a good thing if you’d like to feel the weight of your devices, though. In terms of connectivity, you get the standard package, which includes 4G LTE, Wi-Fi, Bluetooth 5, and NFC. The device also comes with an under-display optical fingerprint reader, which is super-fast.

OnePlus has packed a relatively high 4085mAh battery inside this big device. Due to the light OxygenOS that it runs on, you can get a decent amount of screen-on time and standby time. When it comes to recharging it, you have the support of the 30W WARP Charging, which can refill 50% of battery in less than an hour. It still doesn’t have wireless charging support, by the way.

So, OnePlus 7T Pro is one of the devices with two physical slots for the SIM card, while also giving you a best-in-class camera experience on the go.

Pros
  • Excellent triple-camera setup
  • 90Hz QHD+ display
  • Full-screen display
  • Pop-up selfie camera
  • Flagship-grade chip
Cons
  • No wireless charging/5G
  • RAM & Storage: 8GB + 128GB
  • Processor: Snapdragon 855+
  • Display: 6.5-inch sAMOLED with 90Hz
  • Front Camera: 16MP
  • Rear Camera: 64MP Main + 13MP Telephoto + 8MP Ultra-Wide + 2MP Depth
  • Battery: 4000mAh (with 50W Fast Charging)

Sometimes, you don’t have to spend too much to get a dual SIM smartphone with basic features to handle today’s digital needs. The Realme X2 Pro is one of those devices. On top of all the necessary things, you get 50W Fast Charging as well, if that’s a concern.

One thing that makes the X2 Pro capable of competing with flagship smartphones is the octa-core CPU inside – Qualcomm Snapdragon 855+. This chip has also been coupled with an Adreno 640 to fulfill your necessary gaming needs as well. Together, the SoC won’t let you down on a regular day.

This basic version of X2 Pro comes with 8GB of RAM, which is enough for most users on most days. It houses 128GB of internal storage, which is honestly low, and you cannot upgrade it via SD card either. So, if you want to store more files locally, you should get an upgraded version. It ships with Android 9.0, but you can update it to Android 10, and the overlaying Realme UI is not intrusive.

Although priced under what a typical high-tier device would cost, the display on Realme X2 Pro has a size of 6.5 inches and a resolution of 1080 x 2400. On top of that, the Full HD Super AMOLED panel has a Refresh Rate of 90Hz as well. So, you can enjoy super-smooth scrolling, among other features.

As opposed to what you’d expect from a mid-budget phone, X2 Pro packs a quad-camera setup on the back. It consists of a 64MP primary lens, a 13MP telephoto lens, an 8MP ultrawide lens, and a 2MP depth sensor. This setup does a commendable job of providing you high-quality photographs and 4K video recording at up to 60fps. There is also a 16MP selfie camera that supports 1080p video recording.

When we check its design aspect, the device doesn’t disappoint. The weight of 199g and a thickness of 0.34 inches gives a premium feel to the device in general. Apart from the standard USB Type C connector, the device supports Wi-Fi, Bluetooth 5, GPS, and NFC. Just like the OnePlus devices, X2 Pro also has an under-display optical fingerprint reader.

While the 4000mAh battery is pretty much the standard, the show-stealer is its 50W Fast Charging. According to the company, you can fully charge this device in just 35 minutes. Now, that’s a huge promise for people who keep traveling without access to power and connectivity. As expected from a device of this price tag, it doesn’t have wireless charging support.

This device also has two physical SIM card slots. You can use them on dual standby without the problems of an e-SIM.

Pros
  • Affordable pricing
  • 50W Fast Charging
  • 90Hz AMOLED Display
  • Flagship-standard SoC
  • Versatile connectivity
Cons
  • No expandable storage
  • RAM & Storage: 6GB + 128GB
  • Processor: Snapdragon 855
  • Display: 6.4-inch sAMOLED with 60Hz
  • Front Camera: 32MP
  • Rear Camera: 12MP Main + 13MP Ultra-Wide
  • Battery: 4000mAh (with 21W Fast Charging)

A dual-screen smartphone is as convenient as a dual-SIM smartphone, especially today. If you’re looking for such a competitive device, you should consider what LG G8X ThinQ has to offer. This device combines worth-praising specs with effective dual-screen design.

Like many of the devices on this list so far, LG G8X ThinQ also uses a Qualcomm Snapdragon 855 chip. It’s a powerful chip that can handle two screens at times, even if you are playing some games. The Adreno 640 GPU also performs quite well from the graphics point of view.

The device ships with 6GB of RAM, which isn’t the best for multitasking, especially with two screens. So, you may have to be a little cautious while putting the device under pressure. On the bright side, 128GB of internal storage is more than enough for most people, and you can always trade the dual-SIM functionality for an SD card. It also runs on Android 10, with the LG UX 10.0 on top. The UI looks heavy but is minimal at its core.

So, LG G8X ThinQ comes with a detachable dual-screen setup. That is, in addition to the built-in 6.4-inch Full HD Super AMOLED display, you can connect the extra screen for advanced functionalities. In terms of specs, the panel has a resolution of 1080 x 2340 and a refresh rate of 60Hz.

LG has used a less fancy setup in the camera department. On the rear, you have a dual-camera setup with a 12MP primary sensor and a 13MP ultrawide sensor. These two lenses do a great job, including 4K videos at 60fps, but you may miss the telephoto lens at times. On the front, you can find a 32MP wide-angle lens for selfies and 4K videos.

LG G8X ThinQ has a weight of 192g and an overall thickness of 0.33 inches. In addition to its aluminum frame, you can find Corning Gorilla Glass protection on the back and the front. Connectivity-wise, it’s a jack of all trades, with Wi-Fi, Bluetooth 5, GPS, and NFC. Through NFC, LG also brings a quick payment option. There is also an optical fingerprint scanner under the display.

Once again, we see the standard 4000mAh battery inside the package. The longevity of the battery depends on how many screens you use and the network performance, of course. However, because it comes with a 21W Fast Charger and support for Quick Charge 4, you won’t have trouble in recharging it. You can also use wireless charging at 9W for extra convenience.

While LG G8X ThinQ technically has two SIM card slots, you can use one of them as an SD card slot as well. It provides some level of extra control on any day.

Pros
  • Dual-screen display
  • High-quality camera
  • 21W Fast Charging
  • NFC and LG Pay
  • Premium design
Cons
  • Small battery
  • RAM & Storage: 6GB + 128GB
  • Processor: Snapdragon 730G
  • Display: 5.81-inch OLED with 60Hz
  • Front Camera: 8MP Punch-hole
  • Rear Camera: 12.2MP Wide
  • Battery: 3140mAh (with 18W Quick Charging)

If there is one thing you could never go wrong about Google Pixel devices, it’s their camera. The brand-new Pixel 4A keeps the legacy going. This time, however, you get the near-flagship performance and superior camera details for a budget under $400.

Because it’s a lite version of the already-available flagship device, Google has used a Qualcomm Snapdragon 730G chipset inside. This octa-core processor is coupled with Adreno 618 to provide the standard speed and stable performance. You can’t expect the highest frame rates in intense games, though.

We see the trusty combination of 6GB RAM and 128GB internal storage in this package as well. 6GB of RAM keeps the device capable of handling day-to-day multitasking needs with ease. It also helps in the software optimization section of the camera. Now, coming to the software, Google brings the purest Android version through Pixel. It currently runs on Android 10 but will be one of the first to get the Android 11 upgrade.

For the display, Pixel 4a has chosen something less fancy. The 5.81-inch Full HD OLED panel that still has the standard refresh rate of 60Hz. However, it has HDR and Always-on Display options built-in. On the bright side, the lower resolution of 1080 x 2340 and refresh rate help the device in reducing battery consumption.

Unlike Apple, Google doesn’t want to move away from the single-camera setup completely. That is why you can spot a single 12.2MP primary sensor on the back. In addition to offering superb camera features like HDR+ and Night Sight, Google uses software optimization to make the photos look good, even when there is a single sensor. On the front, you get a punch-hole 8MP sensor as well.

Compared to the flagship devices, Google Pixel 4a is a small device. It weighs just 143g and has a thickness of 0.32 inches. So, if you have a liking for handy smartphones, this is a great choice. In terms of connectivity, the device packs Wi-Fi, Bluetooth 5, GPS, NFC, and even a 3.5mm headphone jack. While everyone else has moved to under-display readers, Pixel 4a still uses a rear-mounted fingerprint scanner.

On paper, the 3140mAh battery on the device is pathetically underpowered. Once again, though, software optimization from Google comes to the rescue. Using Google’s Adaptive Battery feature, this device can easily last for a day. While the device comes with 18W Fast Charging, you still don’t get wireless charging in the package.

Just like iPhone devices, Pixel 4a also uses a combination of a nano-SIM and an e-SIM. You also get a superb set of Google Assistant features with this device.

Pros
  • Extremely affordable
  • High-quality camera
  • Fast Android updates
  • Clean Android experience
  • 18W Quick Charging
Cons
  • Satisfactory performance only
  • RAM & Storage: 4GB + 64GB
  • Processor: Snapdragon 660
  • Display: 6.3-inch Full HD IPS LCD with 60Hz
  • Front Camera: 25MP Primary
  • Rear Camera: 48MP Main + 16MP Ultra-Wide + 5MP Depth
  • Battery: 4000mAh (with 15W Charging)

If you are looking for a dual SIM smartphone that costs less than $200, you should check out the Moto G8 Plus. While you can find even cheaper Android smartphones in the market, this one comes with the right set of basic hardware specs as well.

Like the budget-friendly device we covered, G8 Plus also uses a Qualcomm Snapdragon 660, which packs an octa-core CPU and an Adreno 610 GPU. You cannot use this setup for video editing or heavy gaming, though. However, for the day-to-day Android life, this combination is sufficient.

Coming to RAM and storage, we can see the same style. The device packs 4GB of RAM and 64GB of internal storage. While the device supports storage expansion via an SD card, you will have to give up the dual-SIM system to make that possible. So, as long as you need two SIMs working, you are left with around 50GB of storage. The device is using a rather clean version of Android 10.

Once again, we see an IPS LCD, which is of inferior quality when compared to OLED. However, this 6.3-inch panel provides good viewing angles for media consumption. As you can guess, you are getting the standard 1080 x 2280 resolution and 60Hz refresh rate.

Moto G8 Plus also comes with a triple-camera setup on the back. You can switch between the 48MP primary sensor and the 16MP ultrawide sensor according to your preferences. There is also a 5MP depth sensor that makes portrait shots possible. You can record 4K videos at up to 30fps with the system. On the front, you’ve got a somewhat huge 25MP sensor that supports 1080p recording.

Weighing just 188g and with a thickness of 0.36 inches, the device is pretty compact on paper. However, you will notice the plastic back and frame as something less premium. When it comes to connectivity, you get 4G LTE, GPS, NFC, Bluetooth, and even FM Radio. A slight problem is that the device may not support VoLTE with all networks.

Even with the compact size, Lenovo has included a 4000mAh battery in this package. The company claims it can provide up to 40 hours of usage, which is confusing, to be honest. Nevertheless, thanks to its support for 15W Fast Charging, you can quickly recharge the device. As long as you keep the usage mixed, you can hit a full day on a single charge.

Moto G8 Plus also makes you choose between expandable storage and a secondary SIM.

Pros
  • Truly affordable pricing
  • Smooth performance
  • 4G LTE and NFC support
  • 4000mAh battery
  • Fast Charging support
Cons
  • Low storage options

The Buyer’s Guide

Before you make that final decision to get your favorite dual sim phone, it is essential that you consider certain things so that you can make the most informed decision. With a wide variety of products available in the market and a wide range of factors to consider, it can be certainly an uphill task to pick a model that will suit your needs.

Moreover, it is easy to get distracted by shiny new features in a smartphone, but a pragmatic decision can be reached only by evaluating what your needs are and which factors you should consider before forking out a lot of money.

Before picking a product, you must evaluate your priorities and ask yourself what you actually use your smartphone for daily. For example, for somebody who only spends their time on social media and streaming on YouTube, there is no need to get an expensive device with a graphics card. However, it may be essential for a gamer to spend more money and get a device that provides a smooth gaming experience.

To help you make that informed decision, here is a list of what factors you should consider before clicking on that order button.

1. Operating System and Processor

If you are considering a phone from this list, you have already decided that you will be buying an Android-based smartphone.

Several versions of the operating system are available, and it is preferable to get a device that has the latest version or at least can be updated to it. Every update adds new unique features and functions to your smartphone, so don’t settle for a device that has outdated versions like Lollipop or KitKat rather go for the ones which come with Android Oreo, Pie or even Android Q.

Coming to the processor, this acts as the motherboard of the tiny computer that is your smartphone. Qualcomm processors are usually a safe bet as they have proven themselves over and over in the market.

Kirin processors of Huawei have also made their name as performance-enhancing chipsets. You should also consider getting a phone that has more than 6 GB of RAM so that there is no lag while multitasking.

2. Storage

This is probably one of the most important features of a phone. Although you can use a micro SD card to expand the storage of your smartphone, internal memory is generally preferred over external because of the ability to install more apps.

Also remember that even though smartphones claim to provide 64 or 128 GB of memory, the actual space available is considerably less. So it is always a safe bet to go with a phone that has at least 64GB of memory so that you have sufficient space to save your pictures and music.

However, if you like to game on your smartphone, it is preferable to get a device that has 128 GB of internal memory so that you can run heavy games like Asphalt and PUBG without affecting the functionality of the phone.

Similarly, RAM is a very important factor to consider. At least get 6 GB of RAM so that you do not face hanging and freezing issues when multitasking. For gamers, even more, RAM may be required to run heavy games.

3. Display

The size and type of display are probably one of the most important factors for some people. Most smartphones come with a display that is at least 6 inches in size and is equipped with HD plus graphics.

The bezel-less display is extremely popular these days because they provide full immersion no matter what you do – play games or watch a video on YouTube. Screen size is definitely a factor you should consider before deciding which phone to buy.

Another important distinction is the difference between LCD and AMOLED display. The former offers brighter display and tends to work better in direct sunlight. AMOLED display offers sharp contrast and more saturated colors.

You should also make sure that your phone has Corning Gorilla Glass protection to prevent scratches and minor accidental damage.

4. Camera

Nowadays, more and more people are focused on the camera of the smartphone and listening to the demand of users, manufacturers are also adding more features to phone cameras. However, it is easy to get distracted by a range of features like hybrid autofocus and optical stabilization that sound impressive.

If you are not a photographer or somebody who is passionate about it, there is no use spending a lot of money just to get some features that you are not going to use anyway. If you are only going to use your phone for selfies and occasional photographs with friends, a good quality camera with integrated sensor and good pixel size should be enough for you.

Some phones come with a more powerful front camera instead of the rear camera. This feature can help you save money if you are like me who loves taking selfies but doesn’t use the rear camera much.

5. Connectivity

Most of the phones come with regular connectivity features like Wi-Fi, Bluetooth, and LTE. If you are going to buy a dual sim phone make sure that the phone has 4G connectivity for both sim slots.

Since most carriers work with LTE technology these days, you should also make sure that the smartphone can support that feature on both sim cards.

Additionally, some smartphones come with specialized Wi-Fi stabilization technology which is ideal for people who tend to travel a lot and use a public network.

6. Battery Life

One of the most significant features to consider when buying a new smartphone is battery life. It is, of course, better to get a phone that has higher mAh battery but that’s not all you should consider.

Higher screen resolution tends to consume more battery power, whereas better processors optimize battery life. You should also see if your phone comes with quick charging technology as well as battery saving mode so that you can get the most out of your smartphone every day.

The perfect balance can be achieved by any phone that offers at least 3500 mAh battery. This ensures that you don’t have to charge your phone several times during the day in order to keep it running.

7. Audio Experience

It is also important to consider that your smartphone has good call and music quality, especially if you are someone who tends to listen to music on your phone. Make sure you check the audio quality of the phone before buying it.

8. Other Features

Almost all the smartphones in the market these days come with a variety of sensors like gyroscope, barometer, compass etcetera. You will also find that most phones are equipped with the Global Positioning System or GPS.

However, it is essential to consider whether your phone has a waterproof and scratch-proof display, especially if you travel a lot. If you are prone to dropping your phone, it may be worth investing in a device that comes with Gorilla Glass protection that ensures that your screen will remain scratch proof amidst minor accidents.

9. Budget

Of course one of the most important factors to consider is your budget. You should first decide how much do you want to spend on getting a new smartphone and then look for devices in that price range.

It is also important to consider what you will be using your phone. It is not worth it to spend your entire month’s salary on a device with excessive features that you are not going to use anyway. If you can work well with a cheaper device, there is no point in spending more than what is required.

Once you have decided the budget, you will find a wide range of choices from which you can pick and choose according to your preference.

Frequently Asked Questions

What is the best dual SIM phone in the US?

As we’ve mentioned in our list, when it comes to the best, Samsung Galaxy S20 is our choice. However, if you don’t like Samsung devices for some reason, our best runner up pick would be OnePlus 8T.

Does dual SIM affect the signal?

Not for all the phones, but for a few phones, it could affect. In most cases, neither of the SIMs affects the signal of the other sim card. Whether you prefer to use both the sims at the same time or switch off one of them at a time, the phone uses different circuits to allow both the sims to interact with their corresponding cell towers. This means that the signal of either of the cards will not be affected by the other.

Can I just use one SIM card in a dual SIM phone?

Even if you own a phone with a dual sim slot, there is no reason you can’t use just one sim at a time with your smartphone. Simply leave the other slot empty, and if it is a hybrid slot, you can insert a memory card inside it, and you are good to go.

Do dual SIM phones consume more battery?

Independent radio circuits in the phone actively try to connect the sim cards to their corresponding cell towers. As a result, 2 power circuits are being used simultaneously, which results in the battery draining faster. Even when one of the sims is on standby mode, it still tries to communicate with nearby towers to allow emergency calls in case of absence of a signal. That is why dual sim phones tend to get discharged much more quickly than the ones that only have a single SIM card.

Will dual SIM phones work in the USA?

Yes, several smartphones will support dual sim slots even in the USA. Some of these names include Samsung, OnePlus, Asus, Motorola, Huawei, etc.

Does Verizon support dual SIM iPhone?

Yes, Verizon does support dual SIM iPhone. This means that the company has rolled out eSim cards so that users can add additional sim card to their iPhone without actually inserting a physical sim inside the phone. Previously this feature was only available with AT&T. But now Verizon has also jumped on the wagon and users can easily add a Verizon eSim to their iPhone.

Are there any benefits of buying a DUAL SIM Phone?

It can be extremely useful for businessmen and women to use a phone that has the ability to use a dual sim card. They can use one of the numbers for their work contacts and professional acquaintances. On the other hand, the other number can be used for just personal use. The dual-sim smartphone keeps both the numbers activated all the time so that you don’t have to carry two phones everywhere.

You can also use one of the numbers just for phone calls and the other for connecting to the internet, because data may be cheaper on one plan while another operator may offer better-calling plans.

Having two mobile operators at the same time also ensures that you will not be logged out of the network even if you go to a place where one of the sim cards doesn’t work. With a dual sim smartphone, you can also purchase an extra sim when you are traveling to another country in order to avoid roaming and international charges.

Is dual SIM phone harmful?

Dual sim phones radiate twice as much radiation as the devices have only one sim and this is because every sim stands out EMF radiation as it reaches out to neighboring cell towers.

Even when a sim is switched off on a dual sim phone, it is still communicating with other towers. Therefore a dual sim device tends to release much more radiation than a single sim phone.

As a result, your phone can easily exceed the limit of radiation that is considered normal. If you don’t really need a dual sim device, then you should avoid adding an extra sim in order to reduce the level of radiation that you are exposed to. But if you do have to get one for professional purposes, get a smartphone from a trusted brand and try to use earphones instead of using the device for calls directly.

Does the iPhone have dual SIM card slots?

No iPhones do not have a dual sim card slot. Rather, the company uses the concept of eSim in order to allow its users to use multiple SIM. In this system, you can add an additional plan to your device via the QR code system and confirmation code, but you can only activate one line at a time.

Only Chinese versions of the new iPhones have two sim slots for adding two physical nano sim cards. They released in the rest of the world only have one sim slot and the capacity to add an embedded e-sim. This feature will only get enabled by the Apple iOS software update.

Verdict

We have included a variety of smartphones that come with dual-SIM functionality. As you may have noticed, some of these devices are using the e-SIM technology, Don’t worry, though; an e-SIM is as efficient as a physical SIM card. What matters is this: you have to make sure that you’re getting a smartphone that meets your day-to-day needs. Some of the great options are as follows:

  • If budget isn’t a concern, Samsung Galaxy S20 is the best option for anyone in the US. It comes with not only the most powerful chips but also premium build quality. The Samsung Galaxy Note 20 is also a great option in that category, but it’s more suited for business users.
  • In the middle part of the price spectrum, we have devices like the Google Pixel 4A, Realme X2 Pro and OnePlus 7T Pro. These devices offer a healthy combination of performance, high-quality cameras and super-smooth UI.
  • But, if you cannot spend too much on a dual SIM phone and still need a smoother Android experience, we’d recommend going for the Moto G8 Plus. This device has two physical SIM card slots as well.
  • By the way, if you prefer iOS to Android, you can choose from any iPhone from the current line-up. And, the Apple iPhone 12 is your best shot in terms of performance and screen real estate.

You see, just because you want a dual SIM phone doesn’t mean you have to compromise the other important aspects. And, as we always say, be ready to invest a little more if that gets you a better smartphone experience.
