I was not completely happy but still felt better then the others because I could surf at-list 2x faster then others, even after this being bit expensive network than docomo, idea and many such I still had the same network for this reasons.
I had a good network compared with other networks. I had a very good customer support where I could get time to time assistance about the data plans and many such interesting offers. I was very happy to use My Plan where I could set my priorities. the last and most important thing is that I got 300 waver on my bill which any other network have never done.
I just want to suggest Airtel one thing that if it would little more comedown with price and increase the speed of net a bit more it will be excellent net
