(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 default
alphabet is used and current <fo> (see +CSMP) indicates that GSM
03.40 TP-User-Data-Header-Indication is not set, then ME/TA
converts the entered text into GSM alphabet, according to GSM
07.05, 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
GSM 03.40 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)
