Airtel 4g is the fastest network in india now a days .
It has also having many more amazing plans . I use this since two month and satishfy with it. It the most acceptable network than the others like jio, vodafone etc. In my city in day time the internet speed is about 1-2 mbps. The network is also available in rural area. And the airtel app also very easy and convinient. So in my opinion it is the best network than others.
