Could this be what SAT stands for???
SIM Application Toolkit (commonly referred to as STK) is a standard of the GSM system which enables the Subscriber Identity Module (SIM) to initiate actions which can be used for various value-added services.[1]
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.[2] 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.[1] The SIM also gives commands to the handset such as displaying menus and/or asking for user input.[3]
STK has been deployed by many mobile operators around the world for many applications, often where a menu-based approach is required, such as Mobile Banking and content browsing.[1] Designed as a single application environment, the STK can be started during the initial power up of the SIM card [3] and is especially suited to low level applications with simple user interfaces
