One of the best broadband(in terms of speed) is act broadband or you can say act fibernet(actually there are still installing normal copper cabel)anyway speed is supefast but only problem is FUP(fair usage policy) it limits the speed after consuming FUP, thats the most ridiculous thing I have ever faced and the company said they use fup so they can provide internet to everyone equally without compromising with speed but thats a bu*it they just dont want to upgrade there system to handle more traffic.
By using fup they can handle more users without upgrading there hardware, another thing is cost really high prices is too much if you want to reset your fup it will cost you more than the pakage price, "GO FOR BSNL BUT NOT FOR THIS ONE"
