eSIM, explained.
An eSIM is a SIM card built into your phone. Instead of putting in a piece of plastic, you scan a QR code and a new mobile plan appears on your device. Your normal number stays where it is — the travel plan sits alongside it and carries only data.
The plastic SIM is gone.
For thirty years a SIM card was a tiny chip slotted into your phone. Modern phones replace it with a chip soldered to the board — the eSIM, or embedded SIM. It can hold several profiles at once: your home line, plus as many travel lines as you need.
When you buy an eSIM here, we send you a QR code. Scanning it tells the phone to download that profile and use it for data while you are abroad. Your home line keeps the same number for calls and SMS.
Travel eSIM (this site)
Scan a QR code, pay the price shown before checkout, use the plan alongside your own number. Data only — no voice, no SMS. Add and remove lines as you travel.
Your home carrier’s roaming
Works with no setup at all, and you keep calls and SMS on the same number. What it costs depends entirely on your own carrier’s tariff.
Physical local SIM
Often the cheapest per gigabyte. You have to find a shop and show ID, and your home SIM is out of the phone while the local one is in.
Three steps to get online
The same flow applies to every plan in the catalogue. The iOS wording is shown; Android differs slightly but the steps are the same.
Buy and receive your QR code
Pick a destination and a plan. After your order is confirmed we email you a QR code and an LPA string, which is the same thing in text form for manual installation.
- You can save the QR code as an image.
- The LPA string is there if you prefer to install by hand.
- Install over Wi-Fi — the profile needs a few megabytes.
Scan it while you still have Wi-Fi
Installing the profile needs an internet connection, so do it before you travel or on airport Wi-Fi.
- iPhone: open Camera, point it at the code, tap the banner, then
Continue→Add eSIM. - Android:
Settings→Network→+ SIM→ scan. - Nothing is charged at this step.
Label it and choose what uses it
Give the new line a name you’ll recognise, and point mobile data at it while leaving calls and SMS on your usual number.
- Your number stays on the primary line.
- Switch the travel line off when you get home.
- Don’t delete it — you can reinstall from the same QR code while the plan is valid.
Will my phone work?
eSIM has been a standard phone feature since 2018. Two things to check besides the model: the phone must not be carrier-locked, and some regional variants ship without eSIM even when the model normally has it.
Confirmed supported
Check your exact model
Dial *#06# on the phone. If the list that appears includes an EID number, the device supports eSIM.
Or open Settings → Cellular (iOS) or Settings → Network (Android). If you see “Add eSIM” or “Add cellular plan”, the phone works.
Questions we get every day.
Straight answers, including the ones where the answer is “we don’t know yet”. If yours is not here, there is nobody to ask yet — the Terms explain why, and when that changes.
