13.7 AT+CMGS Send Short Message
The write command transmits a 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 mes-
sage 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.
Syntax
Notes
• If sending fails, for example, if a message is too long, the result code depends on the current setting of the
AT^SM20
command:
If the
AT^SM20 <CmgwMode>
equals 1 (factory default) any failure to send a message is responded with "OK".
Users should be aware, that despite the "OK" response, the message will not be sent to the subscriber.
If the
AT^SM20 <CmgwMode>
equals 0 any failure to send a message is responded with "ERROR".
• If sending fails due to timeout, then
AT^SM20 <CmgwMode>
=1 causes "+CMS ERROR: Unknown error" to be returned;
AT^SM20 <CmgwMode>
=0 causes "+CMS ERROR: timer expired" to be returned.
• Note that some providers do not recognize an @ symbol used in a short message. A widely used alternative
is typing "*" as defined in GSM 03.40 (GPP TS 23.40).
• All characters entered behind the prompt ">" will be recognized as GSM characters. For example, "Back-
space" (ASCII character 8) does not delete a character, but will be inserted into the short message as an addi-
tional physical character. As a result, the character you wanted to delete still appears in the text, plus the GSM
code equivalent of the Backspace key.
