Didn't dial-up mobile data also require some facilities within the
network to be available to support it? I may be wrong here, but I
always assumed the network operator had a rack of dial-up modems to
provide the interface to the PSTN for outgoing dial-up calls. If so,
it possible that hardware has been stripped out since the advent of
GPRS.
