Thanks. What tool did you use to make this? Is it some fancy IrDA-
debugger or just software on the Psion?
It's interesting to see that it actually checks AT+FCLASS=?. I know
some people had problems with a Psion and one of the newer phones (was
it a Motorola?) that didn't support faxing. The Psion failed to make a
data connection because the AT+FCLASS=? command failed, even though
the phone supported FCLASS=0 (i.e. data). I think there was a fix for
this problem from Symbian.
If I didn't miss anything, this is the full dialogue between the 8810
and the Psion 5MX:

Some of this is obviously junk. But I do note from the junk that you have
software version 4.05 on the phone while I have 4.03. The solution could
be as simple as that....
Among the commands that are not junk, these are interesting:
AT+FCLASS=0
Sets the fax class to "data". But this is also the default.
AT+CMGF=0
AT+CNMI=1,1,0,0,0
Cannot find these commands in GSM 07.07, and I don't know them
from normal modems. What do they do? Certainly worth trying.
ATM0L2X4S8=4
The speaker and dial tone detector settings are useless (there is
never any dial tone or speaker output), and I cannot see that setting
the comma delay to 4 seconds should make any difference when not using
commas in the dial string.

Yes it can, and it does. I subscribe to data but not fax, which are
separate services in my network. I cannot make or receive fax calls.
If I call the mobile phone from a fax, the phone tells me that it
receives a fax call and if I try to answer it I get something like
"service unavailable". I get the same message when I try to send a fax
from the Psion. Don't ask me how, but the network does differentiate a
fax call from a data call to the same(!) modem. Voice calls and
data/fax calls are handled very differently by the network, so it has
to know the difference between them.
