Opera’s eSIM is a data-only travel connection: it can give a compatible Android phone mobile internet, but it does not replace your existing phone number or provide a regular voice-and-text plan. It may replace your carrier’s roaming data for a trip if Opera supports your destination and its allowance, validity, and price suit your needs.
What Opera’s eSIM replaces—and what it doesn’t
Opera says its eSIM provides mobile data for the phone, not just for the Opera browser. Other apps, including maps and messaging apps, can use that connection. Opera’s service is powered by Holiday.com and is managed through Opera for Android.
The important distinction is that the eSIM is data-only. It does not take over your existing phone number and should not be treated as a package for ordinary calls and SMS. On a dual-SIM-capable phone, Holiday.com says the regular SIM can remain available for calls and texts while its eSIM supplies data. The exact behavior depends on the handset and carrier. Charges for using your regular number abroad—including calls, texts, or voicemail—still depend on your home plan and its roaming terms.
Internet-based calls and messages can work over data, but that is different from including cellular voice and SMS in the eSIM package. Whether your existing number can make or receive calls and texts abroad also depends on your carrier and any supported Wi-Fi calling arrangement.

Is your phone and destination supported?
Device and app requirements
Opera’s September 29, 2026 announcement says the service is available in Opera for Android, requires Android 10 or newer, and needs an eSIM-compatible phone that is not carrier-locked. Opera says it is not available in Opera Mini or Opera GX mobile. Check the exact phone model’s eSIM support and confirm its lock status with your carrier; having a recent Android version alone does not guarantee compatibility.
Destination availability
Opera listed 47 supported destinations at launch: Albania, Australia, Austria, Belgium, Bulgaria, Croatia, Cyprus, the Czech Republic, Denmark, Egypt, Estonia, Finland, France, Georgia, Germany, Greece, Hong Kong, Hungary, Iceland, Ireland, Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, Malaysia, Malta, Montenegro, the Netherlands, New Zealand, Norway, Poland, Portugal, Romania, Singapore, Slovakia, Slovenia, South Korea, Spain, Sri Lanka, Sweden, Switzerland, Taiwan, Thailand, Türkiye, the United Kingdom, and the United States.

That is the launch list, not a guarantee that every destination or offer will remain available. Opera says paid plans can be purchased worldwide, but check the destination and current plan shown in the app before relying on the service.
Opera’s data allowances, validity, and network
| Offer | Allowance and validity | What to know |
|---|---|---|
| Free allowance | 3 GB, valid for three days | Available in selected markets; Opera says no payment details or email address are needed. |
| Paid packages | 3 GB, 5 GB, or 10 GB; each valid for 30 days after activation in the destination country | Prices vary by destination and package size and are shown before purchase in the browser. |
These figures come from Opera’s September 29, 2026 launch announcement. The free offer is limited to selected markets, and the paid packages have fixed data allowances; they are not the unlimited plans described separately by Holiday.com. Opera says the eSIM connects to 5G where local networks support it and otherwise uses the next-best available network quality. That does not guarantee 5G access or a particular speed at every location.

How to compare it with your carrier’s roaming
Opera can be an alternative for travel data, but whether it is a better choice depends on your trip and your home carrier’s terms. Compare the actual destination offer with what your carrier will charge or include—not just a headline percentage.
| What to compare | Questions to answer |
|---|---|
| Destination | Is your destination supported by Opera now? Does your carrier plan include it, or place it in a different roaming zone? |
| Data and trip length | Will the Opera allowance cover your likely use, and will its 30-day validity cover the trip? Check your carrier’s data cap and any fair-use conditions too. |
| Total cost | What is the current Opera price for that destination and allowance? What would roaming actually cost on your existing plan? |
| Calls and texts | Will you keep the home SIM active, and what does your carrier charge for calls, texts, and other roaming activity? Does your phone and carrier support Wi-Fi calling? |
| Device and setup | Does your Android phone support eSIM, is it unlocked, and can you select the intended SIM for mobile data? |
Opera says its plans were “around 33% cheaper on average than other major eSIM providers.” That is Opera’s own comparison of a 5 GB, 30-day plan in the United States against six other major eSIM providers, using prices recorded on August 24, 2026. It does not establish that Opera will be cheaper in another destination, against every eSIM provider, or compared with your own carrier’s roaming plan.

Set it up before you travel
- Check eligibility and the offer. In Opera for Android, confirm that your phone is eSIM-compatible and unlocked, and check whether the destination and package you want are available.
- Install the eSIM before departure. Opera recommends a stable internet connection for setup. Installing ahead of time reduces the chance that you will need to troubleshoot the download after arrival.
- On arrival, select the Opera eSIM for mobile data. Opera says the plan activates automatically the first time it connects to a network in the destination country. Confirm which line is selected for mobile data in your phone’s SIM settings.
- Review roaming settings on your regular SIM. Opera’s setup guide advises turning off data roaming on the regular SIM to avoid roaming charges. This data setting should not be assumed to prevent every possible charge from your carrier; check its terms, and keep track of which line handles calls and texts.
When it makes sense to use Opera eSIM
- It may suit you if your phone meets the requirements, your destination is supported, and a fixed data allowance is enough for the trip.
- It is not a full-plan replacement if you need the eSIM itself to provide your regular number, cellular voice service, or SMS.
- Check your carrier first if you need to stay reachable on your existing number or are unsure what calls, texts, or roaming activity will cost.
- Compare live terms before buying if price is the deciding factor; Opera’s displayed destination price and your carrier’s actual roaming terms are the relevant figures for your trip.
