I have recently got a HSDPA usb modem (Global wireless usb modem 7.2Mbps) with a BSNL 3g sim.
I have added the following settings in the software,
Dial number: *99***1#
PDP type: IP
obtain DNS server automatically: selected this
obtain PDP address automatically: selected this
After this if I try to connect, it says, Connection Failed, error: 633.
Please help me to configure this and connect to the internet.
FYI, the sim is valid and has the data access limit too of 500GB. I have used this sim in my mobile, it all works like a charm. And I bought this 3g usb modem from dealextreme site.
