I am using Airtel 4g for couple of months. it don’t have a stable internet connection. But I love the the network coverage. Where ever I go I get a decent coverage. About the Internet connection. it gives high speed internet speed(downloading) now and the next second the lowest speed it possible. that really sucks. and another thing I dont like there customer care service. it should give a way to talk to a customer service executive that would be great.
