Subscriber Identity Module (SIM) and Identification Label

SIM

A SIM is required to access the existing local GSM network, or remote networks when

traveling (if a roaming agreement has been made with the provider).

The SIM contains:

• All the data necessary to access GSM services

• The ability to store user information such as phone numbers

• All information required by the network provider to provide access to the network

Identification

Each Motorola GSM phone is labeled with a variety of identifying numbers. The following

information describes the current identifying labels.

Mechanical Serial Number (MSN)

• The MSN is an individual unit identity number and remains with the unit throughout its

life.

• The MSN can be used to log and track a phone on Motorola's Service Center Database.

• The MSN is divided into 4 sections as shown in Figure 28.

unique to the Transceiver 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
