Airtel is really not a network that you are looking for its broadband is very very costly although I admit that its too fast but its really not at all made for middle class people like us .
recently I got an broadband connection on my laptop. it was very bad experience using that .i could not even study my video lectures through youtube.
when I got it installed it was just awesome using it but when last 10 days were left and still 500 mb was left it stopped working. this was really a big cheating with me and now I think that I shouldnt have installed and not have wasted my money. really it was a terrible experience.
