Today, I have got one modem BSNL 3G of Teracom company, I followed the same steps which I had earlier mentioned in my article, but I was surprised, when I was inserting the BSNL 3G Teracom Modem to PC then BSNL datacard default software was automatically opening. Since, original software was opening so I was getting error “Invalid SIM”. Then I uninstalled the BSNL 3G Teracom Modem software from PC and installed only V-CELL software. Now PC was not able to detect the BSNL 3G Teracom Dongle. But, after a few hour, i got the solution and i was able to use another sim on BSNL 3G LW273 Teracom Modem.
Follow The Steps :-
- Uninstall BSNL 3g connecting software from control panel do not uninstall drivers.( HSDPA drivers are installed separately and do not touch them just uninstall software named bsnl3g in control panel)
- Download and Install V-Cell its a software just like BSNL 3g connecting software.
- Insert any Sim card with data plan and enjoy surfing.
