How to keep your home number abroad and still use a travel eSIM
· 3 min read
Short answer: you do not have to give up your number. A travel eSIM is data only, so your home SIM stays in the phone for calls and texts while the eSIM carries mobile data.
The setup in one table
| Line | What it does abroad |
|---|---|
| Your home SIM | Keeps your number. Used for calls, SMS and codes sent to that number. |
| Travel eSIM | Data only: no phone number and no SMS. Used for mobile data. |
Facts worth knowing before you buy:
- Plans from GoEasySim are data only, with no phone number and no SMS.
- Validity starts when the eSIM first connects, not when you buy it.
- Install within 180 days of purchase.
- No account or registration needed. Your QR code appears on the order page within seconds of payment, and no app is needed: scan the QR code or enter the code in your phone's settings.
- One-off purchase. No subscription, no recurring charge.

Why keep the home SIM at all?
- Banks, messengers and two-factor logins often send a code by SMS to your number.
- Friends, family and work can still reach you on the number they know.
- Your phone can show both lines, so you choose which one handles what.
What your phone needs
Dual SIM with an eSIM means one physical SIM plus one eSIM. Apple notes that Dual SIM works with one physical SIM and one eSIM, and that iPhone 13 models and later also support two eSIMs (see Apple: Using Dual SIM with an eSIM). Before you buy, check that your phone supports eSIM and is carrier-unlocked. The phone compatibility guide takes about 30 seconds.
Step by step
- Install the travel eSIM with the setup guide, ideally on home Wi-Fi before you fly.
- Label the lines so you can tell them apart, for example "Home" and "Travel".
- Set mobile data to the travel eSIM. On iPhone: Settings, Cellular, Cellular Data, then choose the travel line. Android menus differ by brand; look for the SIM or mobile network settings and pick the eSIM for mobile data.
- Turn data roaming off on your home line, so it cannot pick up data at roaming rates. On iPhone this is in the settings for that line; on Android it is in the settings for that SIM.
- Check Allow Cellular Data Switching on iPhone. Apple explains that with it on, a voice-only line can switch to use data during a call. If your home line has roaming off, leave it off so your data stays on the eSIM.
- Do a quick test on arrival: load a web page on mobile data, with Wi-Fi off.
Will calls and texts still work abroad?
That depends on your home carrier, not on the eSIM. Receiving calls and SMS on the home line while abroad may need roaming to be allowed for voice and SMS, and your carrier sets the rates. Look up its current terms for your destination before you leave. If a call matters, a messaging app over the eSIM's data is often simpler than a roaming call.
Common mistakes
- Leaving data on the home line, so roaming charges apply while the travel plan sits unused.
- Forgetting that SMS codes go to the home number, then landing with that line switched off.
- Removing the home SIM, which leaves your number unreachable.

FAQ
Can I get a local phone number with the eSIM?
No. These plans are data only: no phone number and no SMS.
Will my home number stop working?
No, as long as the home SIM stays in the phone and the line is on. Whether calls and texts reach you abroad depends on your carrier's roaming terms.
Does my phone need two SIM slots?
No. An eSIM is not a physical card, so one physical SIM plus one eSIM works on compatible phones. Check that your phone supports eSIM and is carrier-unlocked.
