STK

The SIM Application Toolkit (STK) is a set of applications and related procedures, which may be used in conjunction with SIM or Smart Cards during a GSM session. The STK provides mechanisms that enable applications existing in the SIM to interact and operate with any ME (such as the G24-L) that support these mechanisms.

The following scheme shows the SIM Toolkit functionality commands and unsolicited results that are implemented. All these commands are non-basic commands.
