I am using airtel from 2 year experience with is very satisfying. it gives 800-1200kbps speed and voice quality also good but sometimes its lacking, airtel has also cheap price in 400rs. it gives daily 1GB for 70days, wherever I travel I got airtel network they have broad network, their customer care representative are very wise and gentle they handle customer with full of manner way, airtel 4G is one of the biggest 4g network in current time.
