The airtel network has the best network as compared to any other network. recently I have switched tata docomo to airtel network as compare to tata docomo the airtel has the best network the airtel network comes even in highways so no problem to take and receive calls. recently the airtel has introduced an 4g network for high speed internet I have activated a 4g network in my mobile and the internet speed is very fast then expected it gives you a ratio of 10 to 15 mbps speed which is great for the mobile users but it is little bit costly becasue the network has got some great features like 4g and airtel money that your money can be transferred to any other airtel network or vice versa. overall it is one of the best network with a higher price.
