BSNL EV-DO card provides broadband (144 Kbps – 2 Mbps – averaging about 500 Kbps) on the go, with limited roaming. It works well in Windows XP environment. There is Dialer application provided with EVDO for Windows.
What about Linux? Here is no nonsense guide to connect to internet in Linux through EVDO card. In Ubuntu 32/64 bit Linux machine, running this device is pretty much straight forward. Here is how you can install and run BSNL evdo card in your Linux machine: (though you can do this with dozens of different methods with equal number of tools – classic Linux style!)
1 – install kppp if you don't already have. Skip to section 2 if you already have kppp. Connect to Internet with some alternative method, and then use following command to install kppp in Ubuntu:
# apt-get install kppp
2 - Now, run kppp by giving command:
On the kppp window that appears, click on Configure, then click on Accounts tab that appears. Click on New, and then provide connection name such as BSNL, and in telephone number, fill #777. Click OK. Further, click on Modem tab and then click on New. Give it a name such as evdo, then onModem Device dropdown menu, select /dev/ttyUSB0. Click OK twice to save setting. Finally, click on Connect button on KPPP main window. And, Bingo! Your evdo device connects to internet instantly.
Except KPPP installation, the method given above will work well in all major latest Linux Distributions such as Fedora, Mandrive, SUSE etc.
