How to install an eSIM
Two minutes on a Wi-Fi connection, before you fly. Installing does not start your plan — the clock begins when the eSIM first connects in your destination.
Before you start
Use Wi-Fi or your normal mobile data — the install needs a working connection. Have the QR code from your order page open on another screen, or use the activation code to install from the same phone.
Settings → Mobile Service → Add eSIM → Use QR Code. On iOS 17.4 and later you can paste the activation code instead.
Settings → Network & Internet → SIMs → Add eSIM → Scan QR code. Wording varies slightly by manufacturer.
Check three things in your phone's mobile settings: the travel line is switched on, data roaming is enabled for that line, and it is selected as your mobile data line. Roaming sounds wrong but is correct — to the local network, the eSIM is roaming.
