Question: What is the primary source for higher-level procedures, contents, and coding of commands for the SIM Application Toolkit (SAT) feature in the context of the Subscriber Identity Module - Mobile Equipment (SIM-ME) interface?
Option 1: TS 51.011 (Specification of the Subscriber Identity Module - Mobile Equipment interface)
Option 2: TS 11.14 (Specification of the SIM Application Toolkit for the Subscriber Identity Module - Mobile Equipment interface)
Option 3: 3GPP General Architecture Documentation
Option 4: ITU-T Recommendations for Mobile Networks
Explanation: The primary source for higher-level procedures, contents, and coding of commands for the SIM Application Toolkit (SAT) is TS 11.14. This specification provides detailed information on SAT for the Subscriber Identity Module - Mobile Equipment interface, distinguishing it from TS 51.011 which focuses on the transmission aspects across the SIM/ME interface for SAT.
