This is a slowest network in india. Airtel 4G speed like 2g my very bad experince with airtel 4G.This makes me upset. Airtel should improve their network area.I always has some problem with this network. and all the people living in small areas are also facing same problem. as there is a option in airtel.com that you can see that there is a airtel tower is there near your house or not! and I cheacked there there are total 3 airtel tower in my location the nearest one is around 250 meter from my house. I think IDEA 3G best network for me
