Internet Access
Internet access can be setup in Windows Dial-Up Networking (DUN) of the computer that the wireless modem is
serving. Setup procedures will vary according to the type of wireless service provider used. To access
Dial-Up
Networking
on your PC, go to
Start > Settings > Network Connections
.
•
For GSM-without-GPRS, a circuit-switched data connection is used. The user can set up DUN to
make a conventional V.32 modem connection to any terminating modem at the other end. The phone
number specified in DUN can be one supplied by the wireless service provider or another phone
number related to a different dialup modem service (e.g., a dialup modem service phone number from
any commercial or private dialup network).
•
For GSM-with-GPRS, a single DUN number is generally used by all of a wireless provider’s
subscribers throughout its area of coverage; regional, nationwide, continental, etc. Rather than being
a literal phone directory number, as in conventional DUN, this is a code that gives the modem Internet
access.
Connecting to the GPRS Network for Internet Access
After you have inserted the SIM card and the modem is ready for use, you can establish an Internet connection
through a Windows dial-up session.
Note that your wireless provider will charge you for data usage.
