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.
