International Mobile Equipment Identity
What is IMEI?
A 15-digit number that uniquely identifies a phone. Used by carriers to authenticate the device on their network.
In context
You can find your IMEI by dialing *#06# on the keypad, or in Settings → General → About. Some carriers require your IMEI for unlock requests. travel.to does not need your IMEI — eSIM profiles attach to the SIM (ICCID) layer, not the device.
