Response
TA transmits SMS message from TE to network (SMS-SUBMIT).
Message reference value <mr> is returned to TE on successful
message delivery. Value can be used to identify message upon
unsolicited delivery status report result code.

+CMGS: <mr>[,scts>] OK
2) If PDU mode (+CMGF=0) and sending successful:
+CMGS: <mr>[,ackpdu>] OK

For example, if a message was too long <err> code 305 ("Invalid text

Parameter
<da> GSM 03.40 TP-Destination-Address Address-Value field in
string format; BCD numbers (or GSM default alphabet
characters) are converted into characters; type of address
given by <toda>
<toda> GSM 04.11 TP-Destination-Address Type-of-Address octet in
integer format (when first character of <da> is + (IRA 43)
default is 145, otherwise default is 129)
<length> integer type value indicating in PDU mode (+CMGF=0), the
length of the actual TP data unit in octets (i.e. the RP layer
SMSC address octets are not counted in the length).
GSM 03.40 TP-Message-Reference in integer format
<mr>
<scts> GSM 03.40 TP-Service-Centre-Time-Stamp in time-string
format (refer <dt>)
<dt> GSM 03.40 TP-Discharge-Time in time-string format: "yy/MM/
dd,hh:mm:ss±zz", where characters indicate year (two last
digits), month, day, hour, minutes, seconds and time zone.
For example, 6th of May 1994, 22:10:00 GMT+2 hours equals
"94/05/06,22:10:00+08"
<ackpdu> GSM 03.40 RP-User-Data element of RP-ACK PDU; format is
same as for <pdu> in case of SMS, but without GSM 04.11
SC address field and parameter shall be enclosed in double
quote characters like a normal string type parameter
<pdu> For SMS: GSM 04.11 SC address followed by GSM 03.40
TPDU in hexadecimal format: ME/TA converts each octet of
TP data unit into hexadecimal numbers containing two IRA
characters (e.g. octet with integer value 42 is presented to TE
as two characters 2A (IRA 50 and 65)). In the case of CBS:
GSM 03.41 TPDU in hexadecimal format.
