The message reference which is returned back to the application is allocated by the
GSM module. This number begins with 0 and is incremented by one for each outgoing
message (successful and failure case) ; it is cyclic on one byte (0 follows 255).

Note: this number is not a storage number - outgoing messages are not stored.
