80304ST10041a Rev. 7 - 2010-10-14

+CMGS - Send Message

<scts> - TP-Service Centre Time Stamp in Time String Format.

Note: if message sending fails for some reason, an error code is reported.

Note: care must be taken to ensure that during the command execution,

which may take several seconds, no other SIM interacting commands are

issued.

(Text Mode)

AT+CMGS=<da>

[,<toda>]

(Text Mode)

Execution command sends to the network a message.

Parameters:

<da> - destination address, string type represented in the currently

selected character set (see +CSCS).

<toda> - type of destination address

129 - number in national format

145 - number in international format (contains the "+")

After command line is terminated with <CR>, the device responds sending a

four character sequence prompt:

<CR><LF><greater_than><space> (IRA 13, 10, 62, 32)

After this prompt text can be entered; the entered text should be formatted

as follows:

- if current <dcs> (see +CSMP) indicates that GSM03.38/23.038 default

alphabet is used and current <fo> (see +CSMP) indicates that 3GPP TS

03.40/23.040 TP-User-Data-Header-Indication is not set, then ME/TA

converts the entered text into GSM/WCDMA alphabet, according to 3GPP

TS 27.005, Annex A; backspace can be used to delete last character and

carriage returns can be used.

- if current <dcs> (see +CSMP) indicates that 8-bit or UCS2 data coding

scheme is used or current <fo> (see +CSMP) indicates that 3GPP TS

03.40/23.040 TP-User-Data-Header-Indication is set, the entered text

should consist of two IRA character long hexadecimal numbers which

ME/TA converts into 8-bit octet (e.g. the ‘asterisk’ will be entered as 2A

(IRA50 and IRA65) and this will be converted to an octet with integer value

0x2A)

Note: the DCD signal shall be in ON state while text is entered.

Note: the echoing of entered characters back from the TA is controlled by

echo command E
