I am using my Huwai K3770 3G dongle with BSNL Prepay card. I am not able to connect to the internet using Network Manager with bsnlnet or bsnllive APN. My dongle is detected as device on Ubuntu 12.04 and able to create new network connection with network manager.
The only problem I am facing is dongle is not able to connect me to Internet when using BSNL. I am able to establish connection easily with other service providers with one click. (I tried my dongle with BSNL in Windows and it gets connected in few tries but still not working for me in linux)
So please provide me some solution so that I can connect BSNL in Ubuntu.
