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.

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=?

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.

> [AT+CMGF=0]

We've switched into PDU-mode.

[quoted text clipped - 3 lines]

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/forum/showthread.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/Mobile%20and%20Wireless%20Documents/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"

In a long session of searching, I've read only further claims
that reading messages on Symbian phones using AT+C... cellular
commands is not supported.

A totally different approach might be required. A couple of
discussions I came across which seem to be heading in the right
direction are:

http://discussion.forum.nokia.com/forum/showthread.php?t=67314
http://wiki.forum.nokia.com/index.php/Reading_SMS_from_Inbox

You might find the content useful, or suggestive of further
search terms.
