I have 4 MBPS internet at Home fro Airtel. I travel many times withing India. So i want to have a internet with me all the time to use while I'm at remote locations. It could be anywhere in India.

Which is best, prepaid, affordable, fastest, all india coverage Internet to use while travelling? Free roaming is must. Is there any 4MBPS wireless/3g internet available?


I checked Airtel 3G. but it doesn't have free roaming.
