Before this article, I had written an 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 from the Teracom company. I followed the same steps which I had earlier mentioned in my article. Still, I was surprised when I inserted the BSNL 3G LW273 Teracom Modem to PC; then BSNL data card default software was automatically opened. Since the original software was open, I was getting the error “Invalid SIM.” Then I uninstalled the BSNL 3G LW273 Teracom Modem software for PC and installed only V-CELL software. Now PC was not able to detect the BSNL 3G LW273 Teracom Dongle. After a few hours, 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.
