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.
A personality transfer is required when a phone is express exchanged or when the main board
is replaced. Personality transfers reproduce the customer's original personalized details such as
menu and stored memory such as phone books, or even just program a unit with basic user
information such as language selection. U9 telephones use TrueSync® synchronization software
to effect a personality transfer.
Each Motorola GSM device is labeled 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 21.
