counted in the length)

Response
TA sends message from a TE to the network (SMS-SUBMIT). Message
reference value <mr> is returned to the TE on successful message delivery.
Optionally (when +CSMS <service> value is 1 and network supports)
<scts> is returned. Values can be used to identify message upon unsolicited
delivery status report result code.
1) If text mode(+CMGF=1) and sending successful:
+CMGS: <mr>
OK
