A Subscriber Identity Module Application Programming Interface (SIM API) has been defined in TS 42.019 as a technology-independent API by which toolkit applications and (U)SIMs co-operate. That specification is independent of the programming language technology used to create the application, the platform used to host the application and the runtime environment used to execute the application.
This TS includes information applicable to (U)SIM toolkit application developers creating applications using the C programming language ISO/IEC 9899. This TS describes an interface between toolkit applications written in the C programming language and the (U)SIM in order to realize the co-operation set forth in TS 42.019. In particular, the API described herein provides the service of assembling proactive commands and disassembling the responses to these commands for the application programmer.
Software tools, integrated software development environments and software management systems that may be used to create application programs are explicitly out of scope of this TS.
