Unlock BSNL 3G LW273 Teracom Modem Totally Free
Before this article, I had written article about “BSNL Teracom original dashboard for unlocked modems“, “Download BSNL ZTE MF180 Original Dashboard Free“, “BSNL Teracom LW272/LW273 Unlock Software Free Download“, “Unlock teracom LW 272 BSNL in some easy steps“. Today, I have got one modem BSNL 3G LW273 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 LW273 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 LW273 Teracom Modem software from PC and installed only V-CELL software. Now PC was not able to detect the BSNL 3G LW273 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.
This method has been successfully tested on BSNL 3G LW273 Teracom Modem Software Version : V900_V1.0_101112.
