Not Subject to NDA
The type of saved message depends upon the current <fo>
parameter (see +CSMP). For a DELIVER message, current <vp>
parameter (see +CSMP) is used to set the message Service
Centre Time Stamp <scts>, so it must be an absolute time string,
e.g. "09/01/12,11:15:00+04".
SUBMIT messages can only be stored with status "STO UNSENT"
or "STO SENT"; DELIVER messages can only be stored with
status "REC UNREAD" or "REC READ".
If message writing fails for some reason, then an error code is
reported.
AT+CMGW=?
Test command returns the OK result code.
To avoid malfunctions it is suggested to wait for the +CMGW: <index> or
+CMS ERROR: <err> response before issuing further commands.
