12.SIM Toolkit
SIM Application Toolkit (commonly referred to as STK) is a standard of
the GSM system which enables the SIM to initiate actions which can be
used for various value added services. The SIM Application Toolkit
consists of a set of commands programmed into the SIM which define
how the SIM should interact directly with the outside world and initiates
commands independently of the handset and the network. This enables
the SIM to build up an interactive exchange between a network application
and the end user and access, or control access to, the network.
