What is IMEI?

The IMEI (International Mobile Equipment Identity) is a unique number to identify GSM, WCDMA, and iDEN mobile phones, as well as some satellite phones.

The IMEI is only used for identifying the device and has no permanent or semi-permanent relation to the subscriber. Number is used by the GSM network to identify valid devices and therefore can be used for stopping a stolen phone from accessing the network in that country.

How to check IMEI?

The IMEI can be displayed on the screen of the phone by entering *#06# into the keypad on most phones.  It can also be printed inside the battery compartment of the phone.
