6.8 Subscriber Identity Module (SIM) Carrier
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 EDG0208 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.

SIM Integration for the Enfora Enabler EDG0208 Module
The Enabler EDG0208 default configuration does not include an on-board SIM carrier. Enfora provides a
separate product SKU for the Enabler EDG0208 module with the integrated SIM carrier.
6.8.2
Using a Remote SIM with the Enfora Enabler EDG0208 Module
The Enabler EDG0208 default configuration does not include an on-board SIM carrier. If the module is
going to be integrated using a remote SIM, the following guidelines are provided:
To utilize a remote SIM, the integrator must provide a suitable SIM connector on the Application.
The maximum distance from the Enabler EDG0208 to the remote SIM connector must not exceed
25.4 cm (10 inches).
