I am using BSNL internet since 2 years. It gives a good connectivity and good internet speed by which I am able to watch videos on YouTube without buffering. And also I had never faced any problem with the connectivity any where any time. Also I had used BSNL modem in my computer. There is no issue of problem in speed of the internet and is able to get connected quickly. I am able to download any file and apps in much lesser time.
