Airtel is a very famous and broad network.And the first Network to launch 4G in india but as we look at the prices these are out of range of normal people. The prices are not affordable to everyone as its 2G data packs starts from 200+rs for 1GB only.
You can enjoy their 3G and 4G services but at a very high price.Sometimes they deduct money from customers balance without any reason or ainforming customer and they dont have any policy to return that balance.I appreciate the network it is present every even in elevators also:PBut if you dont have enough money for internet and calls I will not reccomend this to you.
