How to install it

Install it at home. When you land, turn data roaming on.

  1. 01
    Install the eSIM

    If you are reading the email on the iPhone, tap the install button and the profile adds itself. Otherwise open Settings › Cellular › Add eSIM and scan the QR code from another screen.

  2. 02
    Give it a name

    The iPhone asks for a label. "Travel" or the country name does the job: you will have two lines and you want to tell them apart at a glance.

  3. 03
    Choose it for data

    Settings › Cellular › Cellular Data, and select the travel eSIM. Leave your usual line for calls and texts.

  4. 04
    Turn data roaming on

    With the travel eSIM selected, turn on "Data Roaming". It is required: without it there is no connection, however backwards that sounds. Turn it off on your usual line so your own carrier cannot charge you.

  5. 05
    Wait until you land

    The eSIM connects when you arrive, not before. The first connection can take anywhere from a few minutes to an hour.

If something goes wrong

I cannot install it+
  • The phone has to be free of carrier locks.
  • The phone has to support eSIM.
  • You need a solid connection: the profile is downloaded and it is not small.
  • It will not work behind a firewall that blocks the download.
  • The QR code must not already have been scanned on another phone.
It is installed but I have no data+
  • Check the travel eSIM is chosen as the data line and switched on.
  • Check data roaming is turned on for that line.
  • Look at the signal bars: if there are any, you are attached to a tower.
  • With no signal, restart the phone for a fresh start.
  • With signal but no data, select the network by hand in settings.
  • Turn off any VPN.
  • Turn the eSIM off and on again.

Will it work on your phone?

Phone not listed?+
  • Type *#06# on the phone keypad. If an EID number appears, it works with eSIM.
  • iPhones work from the iPhone XR onwards. To confirm: Settings › General › About, and scroll down to a 32-digit EID number.
  • On Android: Settings › Network and internet › SIM. If you can add a new SIM, it is most likely compatible. The exact menu name varies by manufacturer.
