EID (“Embedded Identity Document”) is the serial number that is assigned to any eSIM enabled device.

Your EID can be found in the following screens.

You can use the Copy and Paste functions to use the value in the registration process on our web site.

iPhones: Settings > General > About

Android phones: Settings > About phone > Status information
