Hi,
I suggest you do not go for this G broadband connection it is the worst an d useless connection I have come to know staying in bangalore for last 3 years. I have used others connections as well but never faced such a issue. The connection is never steady and the speed is utter waste. They also have limited download however in the given amount of time and speed they do faurd and have some server settings which will never allow to get a good connection. People we should raise our voice and stop such service providers as we expect a better and good service when we are paying around 1200 per month for such a useless service.
You can go for other local connections which are far far better. I am planning to change my connection soon.
