The BSNL 3G data card card gives blazing fast speeds but comes with a downside...It gets disconnected frequently! This way you cannot fire and forget your downloads. It may get disconnected as soon as it see's your back.
There is workaround for this problem. That is to use
windows dial-up.
This works for me and should work for you, still DO IT AT YOUR OWN RISK!. I dont take any responsibilty of something going wrong to your system.
1) I assume that you have installed the bundled software inside the USB 3G data card and you can connect the 3G internet form it AND the device is connected to the system.
2) Open Device Manager. The "HSPADataCard USB Modem" should be listed there. Right click to open properties. In the open window choose the "Advanced" tab. In the 'extra initialization commands:' enter at+cgdcont=1,"IP","bsnlnet". click OK to close the window.

3) From Control Panel open "Network and Sharing Center". From the left hand pane click "Change Adapter Settings". You should see a dial-up connection for your 3G Modem.Right click and choose properties. Select the "General" Tab. In the Phone Number box enter *99# Create a shortcut to the dial-up connection on your desktop. (If not you will have to create Dial-up connection in "Network and Sharing Center". See bottom of the post)

Click OK

DONE!
Right Click the dial-up connection and click "Connect"
Your internet should be running now.
Now windows automatically attempts to connects to the modem if line is dropped.
Note: Dont connect through your BSNL software! It should stay running in the background. you may minimize it to sys tray.
[To Create Dial-up connection open "Network and Sharing Center". Click "Setup a new connection or network". Click next. Follow the instructions. Enter phone no as *99# when prompted. Leave username and password blank when prompted.]
