    The best way to unlock ur huawei e173Bu-1 modem is just to download the latest mobile partner and use it. The process is: 1st uninstall the dialing software provided with ur modem from ur pc (i mean Airtel for ex.)Plug ur modem.Download the software and install it. It will do every thing automatically. At last u would see that ur modem would have installing software with name mobile partner instead of the previous. To check that ur dongle is unlocked or not check it with DC unlocker. link for mobile partner:http://adf.ly/DI0Fs or http://www.unlockurdevice.blogspot.in/2012/09/mobile-partner-indian-version.html and link for dc unlocker: https://www.dc-unlocker.com/download/soft.php?file=ioWat55F

    It works with old airtel huawei E173bu-1. Now i think your Airtel Huawei E173bu-1 firmware is of Jun 2012, and it will not work on your latest firmware. You have to wait for another firmware. You can leave your modem DC log to get helped.

      I know this issue with above mentioned firmware, better purchase DC Unlocker 4 credits and unlock hassle free. There is no solution anywhere over the internet.
