6.7. Subscriber Identity Module (SIM) (Pins 42, 43, 44, 45, 46)

The SIM, an integral part of any GSM terminal device, is a "smart card" that is programmed with
subscriber information:
 The user information consists of an International Mobile Subscriber Identity (IMSI)
number, which is registered with the GSM provider, and an encryption Ki (pronounced
"key"). This information consists of a microprocessor and memory installed on a plastic
card.
Note: The SIM is not provided with the Enfora Enabler LPP G module. The SIM must be
obtained from the GSM service provider and must be provisioned by the operator for data
and/or voice. Always take care to protect the SIM: the GSM terminal will not operate without
the SIM installed.
The SIM provides the IMSI for authentication. To gain access to the GSM network, the network
must recognize the IMSI number, and the terminal must be able to properly decrypt the data sent
by the network. The SIM also serves as a buffer for SMS messages, storing the message for
transmission until a radio link is available and buffering received messages until retrieved.
