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 III-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.

Using a Remote SIM with the Enfora Enabler III-G Module (Pins 76, 78, 80, 82, 84)

The Enabler III-G module default configuration does not include an on-board SIM carrier.
The module supports the use of 1.8 V and 3 V SIM cards. The module includes a hardware
interface module dedicated to Universal Subscriber Identity Module (USIM). All baud-rates
defined in ISO 7816-3 standard are supported for high-speed transmission.
The module optionally includes an on-board SIM carrier. All other modules require a remote SIM
carrier/connector. 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.
•
The maximum distance from the module to the remote SIM connector must not exceed
25.4 cm (10 inches).
•
External ESD Protection is Required;
15 kV Air Discharge;
8 kV Contact Discharge;
