An International Mobile Equipment Identity (IMEI) number is a unique 15-digit code that identifies a mobile phone device. It is used by the phone’s network to track the device and prevent it from being used on unauthorized networks. The IMEI number can also be used to track a lost or stolen phone.
The IMEI number is usually printed on a sticker on the back of the phone, or it can be found by dialing #06# on the phone’s keypad. It is important to keep the IMEI number safe, as it can be used to track the phone if it is lost or stolen.
