★ International Mobile Equipment Identity is a number usually unique for identifying GSM,WCDMA and iDEN mobile phones.
★ It is generally printed inside the battery compartment of the phone.
★ The number can be displayed on the screen by entering *#06# into the keypad on most of the phones.
★ A stolen phone can be stopped from accessing the network within the country, by using IMEI number for valid devices.
★ Unlike CDMA/MEID's electronic serial number, the IMEI is only used for identifying the device and has no permanent relation to the subscriber
★ The subscriber is identified by IMSI number, stored on the SIM card, which then can be transferred to any other handset.
