Hi frnds iam again here to share my experience about 3g bsnl modemDo you know we can use airtel,vodafone,ata docomo and idea by simple one click in bsnl 3g data card..
First of all i need to tell that there are two types of locking first is phone enanbled software and second thing is firmware.... in our bsnl case we dont need to ake so much pain to get unloked as it is just one click software to unlock.. k now read just post and enjoy with bsnl 3g card using airtel,vodafone,tata docomo and idea.... iam personally using this trick and enjoying like any thing
k lets start our trick
I have purchased my BSNL 3G device ( Model no : LW272 ) in the start of year 2010, during this time no other providers were not available in the 3G market.
But time changes and slowly players like Docomo, Airtel and Vodafone etc guys entering market. So I was curious to know/try whether the same BSNL USB Data card can help me if I would like to shift to new operator in future. Luckly my device is not Hardware locked but it is just software locked. If it is hardware locked also we need to flash the memory.
In this BSBL 3G teracome device model no LW272 it is just interface software locked. Thats why it shows " Unauthorised sim, your modem will get closed now" .
So I tried the below steps and worked fine for me with tata docomo and enjoying like anything
1. Install BSNL 3G software initially comes with the device to support the modem by installing the drivers.
2. Then check if you have still BSNL 3G sim working whether is connecting or not.
3. Once it is working as expected , go to the install location of BSNL 3G device software Ex : C:\Program Files\BSNL 3G Data Card\BSNL 3G and rename the BSNL 3G.exe to some thing else.
To prevent it running from the start of device.
now download this software and click below to download software
so just install the downloaded software and enjoy dudes.... any help just comment i will always to help you out bye bye
