2.1 SUBSCRIBER IDENTITY MODULE (SIM) CARD
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 service provider, and an encryption Ki (pronounced “key”). This information
consists of a microprocessor and memory installed on a plastic card. To install the
SIM card into the modem, insert the SIM card in the modem as shown below in
Figure 3.
Note: The SIM is not provided with the SA-G+ modem. The
SIM must be obtained from the GSM service provider and m
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.
