GSM1308 Quad-Band

SA-G+ User Manual

GSM1308UG001 7 Version 1.02 – 10/29/08

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 SA-G+ 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.

After inserting the SIM card,

you MUST move the SIM lock

switch to the left. If the lock is

open, there will not be power

to the SIM.

Insert the SIM card

here – please note

that the notch

must be in the

upper left hand

corner.
