3GPP TS 27.005 AT COMMANDS FOR SMS AND CBS
141 HSPA+ AT Commands Reference Guide
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. Format text as follows:
„
If current <dcs> (see +CSMP) indicates that GSM03.38 default
alphabet is used and current <fo> (see +CSMP) indicates that
3GPP TS 23.040 TP‐User‐Data‐Header‐Indication is not set, then
ME/TA converts the entered text into GSM alphabet, according to
GSM 27.005, Annex A. Use backspace to delete last character. You
can use carriage returns. After every <CR> entered by the user the
sequence <CR><LF><greather_than><space> is sent to the TE.
„
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 23.040 TP‐User‐Data‐Header‐Indication is set. Entered
text consists of two IRA character long hexadecimal numbers
which ME/TA converts into 8‐bit octet (for example the ‘asterisk’
is entered as 2A (IRA50 and IRA65) and this is converted to an
octet with integer value 0x2A)
Note: The DCD signal is in ON state while text is entered.
Note: The echoing of entered characters back from the TA is controlled by echo command E
To write the message issue Ctrl‐Z char (0x1A hex).
To exit without writing the message issue ESC char (0x1B hex).
If message is successfully written in the memory, then the result is sent in the format:
+CMGW: <index>
where:
<index> ‐ message location index in the memory <memw>.
If message storing fails for some reason, an error code is reported.
Note: Make sure that no other SIM interacting commands are issued during the command execution.
Note: It is possible to save a concatenation of at most 10 SMs. The maximum number of characters depends on
the <dcs>: 1530 characters if 3GPP TS 23.038 default alphabet is used, 1340 characters if 8‐bit is used, 670
characters if UCS2 is used. If entered text is longer than this maximum value an error is raised.
Note: In text mode, both SUBMIT and DELIVER messages can be stored in SIM.
The type of saved message depends upon the current <fo> parameter (see +CSMP). For a DELIVER message,
current <vp> parameter (see +CSMP) is used to set the message Service Centre Time Stamp <scts>, so it has to be
an absolute time string, for example "09/01/12,11:15:00+04".
SUBMIT messages can only be stored with status "STO UNSENT" or "STO SENT"; DELIVER messages can only be
stored with status "REC UNREAD" or "REC READ".
