4.1 SIM Card to GSM Module Assignment

Basically, there are two types of SIM card assignment to a GSM module in a GSM gateway.

Hard SIM Card Assignment

Go to the GSM menu and select a GSM module in the selected GSM gateway. Click on Edit in the module row. Select the required SIM Board in the Hard linked SIM section and then the required SIM card. Now the SIM card IMSI code should be displayed in the Hard SIM column in the SIM card overview. The Hard linked column of the SIM menu in the SIM card overview displays information on the GSM gateway and the GSM module to which the SIM card is assigned (gw4 ch12, e.g.).

Assignment According to Rules

Move to the Rules menu and click on Add rule. In the submenu select the GSM group to which the required GSM module is assigned. Now select the SIM group to which the required SIM card is assigned. Choose the SIM card selection method for the group. Refer to the Add Rule subsection for details on the rule types if necessary. Finally, select the days and time intervals for the rule to be applied.

Caution

Remember that one SIM card may be assigned to one GSM module only at a time. If the GSM gateway is disconnected temporarily from 2N^®SIM Star Server, the SIM cards assigned to the disconnected GSM gateway modules shall remain assigned to these GSM modules until the gateway is reconnected to 2N^® SIM Star Server!
