How to install an eSIM on iPhone and Android

Updated 12 November 2026

Buy the eSIM, then scan its QR code from your phone's settings, on Wi-Fi, before you leave. When you land, choose the eSIM for mobile data and turn on data roaming for it. Your own number keeps working for calls and texts.

On iPhone

  1. 1Open Settings, then Cellular or Mobile Service, then Add eSIM.
  2. 2Choose Use QR Code and scan the code the provider sent you.
  3. 3Give the line a name, like "Travel", and keep your own line for calls and texts.
  4. 4When you land: in Cellular Data, pick the travel line, and turn on Data Roaming for it.

On Android

  1. 1Open Settings, then Network & internet or Connections, then SIMs or SIM manager.
  2. 2Tap Add eSIM or Download a SIM and scan the QR code.
  3. 3When you land: set Mobile data to the eSIM and turn on Roaming for it.

Menu names change between brands and versions, but the steps are the same.

If something goes wrong

  • Most QR codes work only once: do not delete the eSIM after installing it.
  • No signal after landing? Check that data roaming is on for the eSIM line, then restart the phone.
  • Still nothing? The provider's support can check the eSIM from their side.

Questions

Can I install an eSIM before my trip?

Yes, and it is the best time: on Wi-Fi at home. Many plans only start counting days when they first connect abroad.

How do I know if my phone supports eSIM?

On most phones, dialling *#06# shows an EID number when eSIM is supported. The phone must also be unlocked.

Do I need to turn on data roaming?

Yes, for the eSIM line: a travel eSIM uses local networks as a roaming partner. Leave roaming off on your own line if you want to avoid its charges.
