The most common installation errors for an eSIM on Android are as follows:

1. Can’t add eSIM

This error occurs when your device is locked by your carrier, which means that the eSIM will work with the network of the carrier that locked it. To check if your Android is carrier-locked, follow these steps:

Go to Settings > Connections > Mobile networks > Network operators > Disable the Select automatically option > Wait 30 seconds to see the available carriers.

If you only see your carrier's name, your phone is locked. If you see multiple carriers, your Android device is unlocked and can use an eSIM.

Turn off Airplane Mode.
