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 data and/or fax calls. If
your account is provisioned for CSD, then all you need is to install the phone
as a modem with Windows Dial-Up Networking. For more information, see my
