Airtel is the bestest network.It gives you the best network connection. In rural areas the network bars in our phone is zero if we are using other companies simcard for ex-Aircel. But if we are using Airtel simcard then we have 3/5 network bars. In also remote areas we have atleast 1/5 or 2/5 network bars. But we can't get any network coverage in remote areas by other network service provider. And yes it has a very costly data packs and other service charges but in all that data packs are very high in comparison of all other network provider
