A GSM phone has no real dialup modem, just a sort of virtual modem which
makes a connection to a carrier's IWU (Inter Working Unit), located in some
service center. The IWU has the actual modem that can make analog data calls
and/or fax calls over the PSTN (public switched telephone network). If the
carrier doesn't provide an IWU, or if your account isn't provisioned for CSD
(Circuit Switched Data), then a GSM phone cannot make data and/or fax calls.
Regardless, my recent tests suggest that Cingular has turned off IWU support
for faxing, making this a moot issue for any GSM phone.
