Sends a message from a TE to the network (SMS-SUBMIT). Message reference value <mr> is returned to the TE on successful message delivery. Optionally, when AT+CSMS <service> value is 1 and there is network support, <ackpdu> is returned. Values can be used to identify message upon unsolicited delivery status report result code. If sending fails in a network or an ME error, final result code +CMS ERROR: <err> is returned. This command is abortable.

•<length> must indicate the number of octets coded in the TP layer data unit to be given (i.e. SMSC address octets are excluded).

•The TA shall send a four character sequence <CR><LF><greater_than><space> (IRA 13, 10, 62, 32) after command line is terminated with <CR>; after that PDU can be given from TE to ME/TA.

•The DCD signal is in the ON state as PDU is given.

•The echoing of given characters back from the TA is controlled by V.25ter echo command E.

•The PDU shall be hexadecimal format (similarly as specified for <pdu>) and given in one line; ME/TA converts this coding into the actual octets of PDU.

•When the length octet of the SMSC address (given in the <pdu>) equals zero, the SMSC address set with command Service Centre Address +CSCA is used.

•Sending can be cancelled by giving <ESC> character (IRA 27).

•<ctrl-Z> (IRA 26) must be used to indicate the ending of PDU.
