This is a MO Forward

This is a MO Forward (Operation Code = 46) MSU containing a MT-DELIVER message (Message type ind. (0) SMS-DELIVER).
The main MAP parameters are:
IMSI (sm-RP-DA) => the IMSI of destination phone
Service centre address OA (sm-RP-OA) => the short message originated from here
sm-RP-UI => contains the sms sender number (TP-Originating Address) + the main body of sms (TP-User data)
