From my experience till now its a worst network in my area Naya Bazar Dhanbad. I have seen the advertisement in the television every time that it is a widest network so I have bought an Airtel Postpaid sim.
But after that I have been using from 2 years but it never have full network on my cell phone in my area. Everytime the call ends in between and I have to call again. Due to the worst network the 3G internet also not work at all. Airtel is also very very expensive so I will not recommend anyone for airtel.
