You can use

AT+CMGF=0 put the device into PDU-mode
AT+CMGL=<stat> read all <stat> messages

where <stat> is 0-4 as follows:

0 received unread message
1 received read message
2 stored unsent message
3 stored sent message
4 all messages

(GSM 07.05). Eg,

AT+CMGL=0

But bear in mind that "AT+CMGL" changes the status of any unread
messages it lists to "read".

You could also use "AT+CMGR", or even "AT+CNMI". But "AT+CMGL"
is the most straight-forward command.

hyper terminal and used the command AT+CMGF=0; which in returns OK.

Can you try the following commands (in order), and post the
results back? Maybe you could copy and paste that whole part
of the Hyperterminal session. There's quite a few commands in
the list, but they'll paint a good picture of what the phone
can do SMS-wise.

AT+CMGF=?
AT+CSMS=?
AT+CSMS?
AT+CMGF=0
AT+CPMS=?
AT+CPMS?
AT+CMGL=?
AT+CNMI=?
AT+CMGR=?
AT+CESP=?

OK

[AT+CSMS=?]
+CSMS: (0)
OK

[ AT+CSMS?]
+CSMS: 0,1,1,1
OK

[AT+CMGF=0]
OK

[AT+CPMS=?]
+CPMS: (),(),()
OK

[AT+CPMS?]
+CPMS: ,,,,,,,,
OK

[AT+CMGL=?]
ERROR

[AT+CNMI=?]
ERROR

[AT+CMGR=?]
ERROR

[AT+CESP=?]
ERROR

and plzz tell me if der is any website or tutorial so that i can know

Within the GSM standards (Technical Specification GSM 07.05 in
particular), this is a mandatory command, and your result
indicates that both text-mode and PDU-mode are supported.

This is a mandatory command, with the result saying that Phase 2
(not the later Phase 2+) command syntax is supported.

We've switched into PDU-mode.

This is another mandatory command, asking what message storage
is available ("AT+CPMS=?") to you, and what storage is
presently selected ("AT+CPMS?"). You've been given a null
result.

These are optional commands, and are obviously not implemented
on this phone.

I have a bit of a problem with this conclusion, but (unless I'm
missing something) they exhaust the possibilities for reading
SMSs directly to a computer (at least in PDU-mode) using
standard GSM commands. A quick google search shows Oxygen
Phone Manager being sold for the Nokia N72, so there may be an
alternative method.

Further searching has produced the statement: "the AT commands
to retrieve sms messages are not supported by Symbian phones"
http://discussion.forum.nokia.com/f...ad.php?t=101608

I don't have a Symbian phone, and haven't seen this aspect
discussed on alt.cellular.gsm before. I haven't got any
further imformation on Symbian implementations like the N72 at
this stage.

You can download GSM standards free from www.etsi.org (after
registering your e-mail address), or www.3gpp.org. I prefer
ETSI, because I find it easier to get PDF format files there
(rather than Word format). For dealing with SMS, you'll need
GSM 07.05 (for this phone, select a Phase 2 version), and
probably GSM 03.40. For PDU-mode, you'll need GSM 03.38 too.

The Siemens PDF publication "SMS with the SMS
PDU-mode" is worth a look as well:
http://www.jazi.staff.ugm.ac.id/ Mo...sms_pdumode.pdf

I'm not optimistic, but you could try reading the messages in
text-mode on this phone:

AT+CMGF=1
AT+CMGL="ALL"
