AT+CMGS Send SMS message

Syntax

Command Description

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.

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.

• In text mode, the maximum length of an SMS depends on the used coding scheme: It is 160 characters if the

7 bit GSM coding scheme is used, and 140 characters according to the 8 bit GSM coding scheme.
