Yes, two phones can access one number—but only when a carrier or calling service supports it. A carrier’s number-sharing feature may connect a host phone to eligible devices; an app or forwarding service can instead route calls to phones linked to a service number. Neither option is the same as copying an ordinary SIM, and they may handle calls, texts, voicemail, and emergency calling differently.
What “two phones with the same number” can mean
The phrase can describe two different setups:
- Carrier number sharing: A carrier links an eligible device to a smartphone’s number. This depends on the carrier, account, and supported device pairing.
- App-based calling or forwarding: A service lets you use its number in an app or ring phones linked to that number. This does not make two carrier subscriptions one native cellular line.
Before activating anything, check what the service supports for calls, SMS and picture messages, voicemail, caller ID, emergency calling, and outbound calls. “Same number” does not guarantee identical behavior on both devices.

T-Mobile DIGITS
T-Mobile’s DIGITS app is available for Android and iOS, and DIGITS can also be used on the web. The app requires Android 10 or later, or iOS 13 or later, a data connection, location permission, and at least 2 Mbps upload and download speed. T-Mobile says access is free for postpaid lines, subject to additional account and service conditions. See T-Mobile’s DIGITS requirements and setup details.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Message history may not match across devices: T-Mobile says texts and picture messages sent from a device do not appear in the DIGITS app or website conversation thread. On iOS, iMessages sent through iMessage do not sync in the DIGITS app. Check the current service details if unified messaging is important to you.

Verizon Number Share – Mobile
Verizon’s Number Share – Mobile lets a user make and receive calls using one shared number across eligible Verizon LTE devices. The smartphone acts as the host, and Verizon says it can share its number with up to five connected devices, subject to device and account limits. The feature works only on Verizon’s LTE network, and not all smartphone services work on connected devices. Check Verizon’s eligible-device list and Number Share FAQs for the models and limits that apply to your account.
AT&T NumberSync
AT&T NumberSync links a smartphone number to a compatible device. AT&T says a linked device can make and receive calls without the smartphone being turned on or nearby. Compatibility matters: this is not a promise that any second smartphone can use the same native line. Confirm your device and account eligibility in AT&T’s NumberSync setup information.

Use an app or forwarding when you want calls on multiple phones
Google Voice is a separate app-and-service option, rather than a way to share one carrier SIM line. You can make and receive calls in the Google Voice app or on its website. When call forwarding is configured, calls to a Voice number can ring linked phones. Google’s help page describes linking and verifying up to six numbers; a number already linked to another Google Voice number cannot be linked again. See Google Voice’s instructions for linked phones and calls.

Choose the setup that matches what you need
- You want a carrier-linked device to use your existing number: Check your carrier’s number-sharing feature and verify that your exact device pair is eligible.
- You mainly want calls to ring on another phone: Consider an app or call-forwarding service, understanding that it may use a separate service number rather than extend your carrier line.
- You need texts to appear identically on both phones: Verify SMS, picture-message, and iMessage behavior before activation. Do not assume that call sharing also means complete message syncing.
- You need both phones for urgent or emergency calls: Check the provider’s current terms for emergency calling and the behavior of each device before relying on the setup.
Why copying a SIM is not the answer
Ordinary SIMs are not a general-purpose way to make two phones operate simultaneously as the same cellular line. Use a carrier-supported sharing feature or a calling and forwarding service instead, and check its eligibility rules before changing your service.
