Making a GPRS connection.

If you are not able to establish a GPRS connection using your PPP dialer, then check for the correct dialing number, and check for the proper PDP context in the modem.

The correct dialing number is *99***1#.

The proper PDP context will depend on your carrier. The command to input the PDP context is AT+CGDCONT=1,"IP","APN", where APN is the Acces Point Name provided by carrier.

The commonly used APN names are:

T-Mobile: "", and ""

AT&T: "proxy", "public", and "internet"

Cingular: "isp.cingular"
(NOTE: Cingular may require a username and password in the PPP dialer for the connection to establish correctly. This is provided by the carrier.)
