A dialup network is a GSM Circuit Switch Data Service (CSD
for short). Using a dialup network can be likened to using a
home computer's modem, in that before connecting to the
Internet a number must be dialed. As for GPRS, it like the
LANs used at company, where users do not need to dial a
number to access the network. Regular GSM users who are
not using a GPRS network system can only have a dialup
connection to the Internet.
