Airtel is a renowned brand in india, I have been using airtel since I actually started using phones and must say have never complained about the service. Although I have friend who keep on cribbing how bad the network is but I am confident about the network so I recently upgraded to airtel 4g, and then it proves the othera wrong again, It gives super network connectivity and speed and am happy about it all what is said about it is incorrect, I would recommend airtel 4g.
