International Mobile Station Equipment Identity (IMEI)
The International Mobile station Equipment Identity (IMEI) number is an
individual number unique to the PCB and is stored within the unit's memory.
The IMEI uniquely identifies an individual mobile station and thereby provides a
means for controlling access to GSM networks based on mobile station types or
individual units. The full IMEI structure is listed in Table 5.
