Question: What is a prerequisite for a Mobile Equipment (ME) to perform Mobile Originated Short Message control by SIM, as per 3GPP specifications?
Option 1: The ME must have an active internet connection.
Option 2: Service n°37 "allocated and activated" and the ME indicated support in the TERMINAL PROFILE command.
Option 3: The Subscriber Identity Module (SIM) must be of a specific, newer generation (e.g., SIM, USIM, or ISIM).
Option 4: The user must have subscribed to a premium messaging package.
Explanation: This is the correct answer because, according to the specifications, for an ME to perform Mobile Originated Short Message control by SIM, two conditions must be met: Service n°37 must be both "allocated and activated", and the ME must have indicated its support for this feature in the TERMINAL PROFILE command. This ensures that both the service and device capabilities are aligned to facilitate the control of mobile-originated short messages by the SIM.
