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 card 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 net-
work.
Each Motorola GSM device is labelled with a variety of identifying numbers. The
following information describes the current identifying labels.
