Guide for Android

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

The exact path varies by manufacturer, but the logic is the same on all of them.

  1. 01
    Install the eSIM

    Settings › Network and internet › SIM › Add eSIM, and scan the QR code from another screen. If you cannot scan it, nearly every phone lets you type the code in by hand.

  2. 02
    Give it a name

    If your phone lets you label the line, do it. You will have two, and you want to tell them apart at a glance.

  3. 03
    Choose it for data

    In Settings › Network and internet › SIM, pick the travel eSIM as your mobile data line. Leave your usual line for calls and texts.

  4. 04
    Turn data roaming on

    On that same screen, with the travel eSIM selected, turn data roaming on. It is required: without it there is no connection. 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.
