GSM/GPRS Spider SA User Manual
GSM0000PB001MAN 4 Version 1.07 - 02/14/05
3 Installation
3.1 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 Spider SA modem. 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.
