Question: In a SIM-ME interface, when Service n°35 is 'allocated and activated' and an SMS status is '1D', what action does the Mobile Equipment (ME) perform regarding the corresponding record in EFSMSR during the Erasure procedure?
Option 1: The ME skips updating the EFSMSR to preserve storage space.
Option 2: The ME performs a backup of the record before erasing it from EFSMSR.
Option 3: The ME ignores the '1D' status and proceeds with standard erasure without involving EFSMSR.
Option 4: The ME performs the erasure procedure for EFSMSR with the corresponding record in EFSMSR.
Explanation: According to the specified behavior for Service n°35 being 'allocated and activated' and an SMS having a '1D' status, during the Erasure procedure, the ME is required to specifically handle the corresponding record in EFSMSR by performing the erasure procedure for it, ensuring consistency across all message storage areas when messages are deleted.
