Airtel is one of the first Indian mobile operator which brought 4G. No doubts that 4G is all about packet data. This company launch this network in 2013 in some metropolitan areas and because of limited users, the internet speed is quite excellent but as traffic increases on that network it has gone slow but after all of this, you can get 10 -15 mbps speed easily because environment matters a lot in mobile technologies.The performance is good and connected very easily.
