Question: What action does the Mobile Equipment (ME) take if the Universal Integrated Circuit Card (UICC) responds with '93 00' to an ENVELOPE (MO SHORT MESSAGE CONTROL) command for a Mobile Originated (MO) Short Message?
Option 1: Send the short message with the addresses unchanged
Option 2: Send a new ENVELOPE command with an updated serving cell
Option 3: Abort all pending MO short message attempts
Option 4: Not send the short message but may retry the command
Explanation: When the UICC responds with '93 00', it indicates a condition not allowing immediate sending of the short message. The ME is instructed to not send the message at that moment but may retry the command after resolving the underlying issue or changing conditions, suggesting a temporary block or condition requiring re-attempt.
