The International Mobile Equipment Identity (IMEI) is a unique number that identifies a mobile phone. It is used by the network operator to track the phone and prevent it from being used on other networks. The IMEI can also be used to track a lost or stolen phone.
There are several ways to check the IMEI of a BlackBerry phone. One way is to dial *#06# on the phone’s keypad. The IMEI will be displayed on the screen.
