Identification
Each Motorola GSM device is labelled with a variety of identifying numbers. The
following information describes the current identifying labels.
Mechanical Serial Number (MSN)
The Mechanical Serial Number (MSN) is an individual unit identity number and
remains with the unit throughout the life of the unit.
The MSN can be used to log and track a unit on Motorola's Service Center Database.
The MSN is divided into 4 sections as shown in Figure 17.
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 3.
