I have been using airtel since my early days. and i’m satisfied using it. I also used other mobile service providers, but they all fail to give network coverage in my area. Airtel is the best among them and provides quality service. One Problem of Airtel is that it is a bit expensive as compared to others. But, internet speed is quite decent so, one can spend and get good internet browsing experience... Be it gaming or surfing not much issue faced...
