# ME - Mobile Equipment ### ME - Mobile Equipment Mobile Equipment (ME) refers to the physical hardware of a mobile device. This includes components like the phone casing, battery, screen, and internal electronics that facilitate communication and functionality of the device. The ME is identified by a unique IMEI number. ### IMEI - International Mobile Equipment Identity The International Mobile Equipment Identity (IMEI) is a unique 15-digit number used to identify mobile devices.
