Airtel network is so pathetic and I think this is the worst network ever I have seen in india I had bought this airtel sim 8 month ago but the network and internet service is so bad and slow as compare to other network. And it has the highest net charges plans for 3g and 4g consumers I had been recharging this network but I leave it. And the customer service of this network is bad you have to wait to connect to the customer care assistant for and a hour. So my suggestion is not to join this network if you want to surf better and speed internet.
