> 13.20 | AT^SCMS Send Concatenated Short Messages

> Sending a concatenated message is similar to sending a "normal" message, except that each segment of the concatenated message must be identified by the additional parameters <seq>, <ieia> and <ref>. To send all segments of the message one by one, the AT^SCMS write command must be executed for each segment.
> The write command transmits one segment of a concatenated short message from TE to network (SMS-SUBMIT).
> After invoking the write command wait for the prompt ">" and then start to write the message. To send the message simply enter <CTRL-Z>. After the prompt a timer will be started to observe the input.
> To abort sending use <ESC>. Abortion is acknowledged with "OK", though the message will not be sent.
> The message reference <mr> is returned to the TE on successful message delivery. The value can be used to identify the message in a delivery status report provided as an unsolicited result code.
