Your activation code

Three ways to use the same code

Your order page shows a QR code, a one-tap install link, and the individual fields your phone asks for. They are all the same eSIM — you only need one of them to work.

An eSIM installs only once. Don't delete the plan from your phone until your trip is over, because the code can't be redeemed a second time.

Scan the QR code

Needs a second screen

Open your order on a laptop or another phone, then scan it with the phone that will use the eSIM. A phone can't scan a code displayed on its own screen.

Tap "Install on this iPhone"

iOS 17.4 and newer

Open your order page on the iPhone itself and tap the install button. iOS passes the code straight to the eSIM installer — nothing to scan or type.

Enter the details manually

Works on every device

Choose "Enter details manually" on your phone, then copy the SM-DP+ address (the server) and the activation code (your one-time ticket) from your order page. Leave any confirmation-code field blank.
