What is an IMEI number?
An IMEI (International Mobile Equipment Identity) identifies a mobile phone based on the 3GPP and iDEN standards as well as certain satellite phones. Mobile phones usually carry the number inside the battery compartment. The number can also be seen on the screen by entering the following code: *#06#. In GSM networks, the IMEI number identifies valid devices. When a phone is stolen, the provider can block it from accessing the network through this number.The phone then is rendered useless for the specific GSM network and sometimes on other networks too. The IMEI is only identifying the device, not the subscriber.
