Choose an unlocked phone whose exact regional model supports the SIM arrangement you need, can keep the right lines active together, and works on your destination carrier’s network. Then compare roaming, local prepaid service, and travel eSIM plans. An “eSIM” or “dual-SIM” label alone does not guarantee compatibility.
Decide what you need your home number to do
Start with the job your home line needs to perform abroad. Do you need to receive calls or SMS verification codes, make ordinary calls, or simply keep the number available while a separate line handles data? Your answer determines which SIM arrangement and plan features matter.
- Keep a home physical SIM and add travel data: Look for a phone that supports a physical SIM and an eSIM at the same time, and confirm both carriers allow the setup.
- Use two eSIMs: Check that the exact phone variant can keep two eSIM profiles active simultaneously, not just store multiple profiles.
- Use two physical SIMs: This may suit travelers who need two physical cards, but the feature is region- and model-dependent. Verify the exact SKU rather than relying on the phone family name.
- Use eSIM only: Confirm that your home and destination providers can supply eSIM service and that you can access the necessary activation method.
Also check what happens to your home line when it remains active: your home carrier may charge roaming fees even if you select a travel eSIM for data.
Check SIM hardware and simultaneous-line support
There is a difference between how many SIM profiles a phone can store and how many lines it can use at once. Confirm the physical tray, eSIM support, and active-line combination for the precise regional model you would buy.

iPhone
Apple’s current Dual SIM guidance says eSIM setup requires an iPhone XS, iPhone XS Max, iPhone XR, or later, and a carrier that supports eSIM. iPhone can use a physical SIM and an eSIM; iPhone 13 models and later can also use two eSIMs. Using two carriers requires an unlocked iPhone unless both plans are from the same carrier. See Apple’s Dual SIM with an eSIM guidance.
Regional exceptions matter. Apple’s iPhone model and band reference identifies model-specific hardware and cellular bands. Apple’s travel guidance also notes China mainland eSIM exceptions and that certain Hong Kong and Macao phones have two nano-SIMs. Check the exact market version before purchase.

Google Pixel
Google says Pixel 3a or later can use one physical SIM and one eSIM. Pixel 7, Pixel 7 Pro, or later can use two eSIM profiles at once when the operator permits; depending on phone and operator, the arrangement can instead be one eSIM and one physical SIM. Google’s dual-SIM instructions explain the operator qualification.

Confirm the phone is unlocked and the carriers support the setup
A phone that has the right hardware can still fail with a second provider if it is carrier-locked or the operator does not support the necessary eSIM or multi-line feature. Apple says an iPhone must be unlocked to use another carrier while traveling, unless both plans are from the same carrier. Google advises Pixel users to check with their operator because eSIM and Dual SIM Dual Standby availability depends on operator support.
- Ask the seller or home carrier whether the exact phone is unlocked for use with another carrier.
- Ask the home and destination providers whether they support the planned SIM combination and eSIM activation on that model.
- Confirm how to activate the line, including whether setup must happen before departure or can be completed after arrival.
Match the exact model to the destination network
Compare the exact SKU’s supported LTE and 5G bands with those used by the destination carrier. A phone’s family name, eSIM support, or ability to connect in one country does not prove full compatibility elsewhere. Apple publishes model-specific bands in its iPhone model reference; check with the destination operator for its network bands and any additional device requirements. The sources do not establish that any single phone works with every destination carrier.

Understand what two active lines can and cannot do
Keeping two lines active does not mean the phone combines their data connections. Apple says iPhone uses one cellular data network at a time. Google’s Pixel instructions likewise let you choose one SIM as the default for data.
Before travel, decide which line should handle mobile data, which should handle ordinary calls, and where you expect to receive messages. On iPhone, Apple’s travel guidance describes selecting the travel eSIM for data while leaving the home line on; the home line may still incur roaming charges. Menu names and setup prompts can vary by software version and region, so do not assume iOS 26’s documented prompts apply to older software.
Compare the service options for your trip
Choose a plan based on where it works and what it includes, not just whether it is marketed as a travel eSIM. Apple describes four broad options for international travel:
- Home-carrier roaming: Convenient if your existing plan and roaming terms suit the trip.
- Carrier travel pass: Check the pass’s destination coverage, allowance, duration, and fees.
- Local prepaid plan: May provide local service, but confirm how it is sold and activated and whether your phone accepts its SIM format.
- Prepaid travel data eSIM: Compare covered countries or regions, data allowance, duration, activation method, tethering, and whether voice or SMS is included. Data-only plans may not provide a local phone number.
Apple’s travel guidance, dated September 17, 2026, says worldwide prepaid data eSIM providers collectively cover over 190 countries or regions; that is not a guarantee that one plan covers every destination. Actual coverage, price, and terms belong to the individual provider and plan. Google also suggests considering a prepaid international eSIM and activation on arrival to avoid roaming charges, but that does not establish that an eSIM is cheapest or available everywhere. Compare the current terms for your destination in Apple’s international travel eSIM guidance and with the carrier or plan provider.
Quick Recap
Use this pre-purchase checklist
- Write down whether you need your home number for incoming calls, SMS verification, outgoing calls, or only occasional reachability.
- Choose the intended arrangement: physical home SIM plus travel eSIM, two active eSIMs, dual physical SIM, or an eSIM-only setup.
- Verify the exact regional SKU’s SIM tray, eSIM support, and number of simultaneously active lines.
- Confirm the phone is unlocked and both providers support your intended setup.
- Check the model’s bands against the destination carrier and ask about any other device requirements.
- Compare roaming, travel passes, local prepaid service, and travel eSIMs on coverage, data, duration, voice/SMS, tethering, activation, and total price.
- Before departure, follow the provider’s activation instructions, label the lines, choose the data line, and check whether keeping the home line active can trigger roaming charges.
