How to unlock BSNL 3G data card( Model no : LW272 )use it with Airtel and Vodafone TATA DOCOMO 100% WORKING

HERE IS TWO WAYS TO UNLOCK YOUR BSNL3G OR MTNL3G (TERACOM) DATACARD


1. Install the USB modem as usual
2. Create a new APN in the BSNL interface (for docomo it is "tata.docomo.internet"). Make it as default.


3. Check in Windows under installed modem options, there you will have HSPA DataCardPropritary USB MODEM


4. Create a new Dialup with your desired name and use the above modem as modem, dialing number will be *99#, user name and password will be blank
5. Go to the BSNL modem installed directory in Program Files, in my system it is "C:\Program Files\BSNL 3G Data Card\BSNL 3G\" . Change the file name BSNL 3G.exe to something else, for example BSNL 3G.abc so that it will not execute.
6.Now remove your datacard and remove BSNL sim and put whichever the SIM you want (APN should be the same) connect it again to the system. 
7.The green light will glow after 10-15 seconds. Now you can connect using the new dialup connection we made. (Here onwards, every time you can use the dial-up)
It will get connected in 3.6 MBPS. actual speed will be depended on the SIM you are using and the network strength.
