Airtel is a highest used network in India but due to Jio it is gone . I will tell you some points about it that it is recommend or not.
First of all they have very good network at the villages so thats why I like it so much.
Customer service of Airtel is also very good.
Recharging availbility is very good.
Things not like,
It is one of the Indias highest cost network.
4G speed is now good, but when Jio is not there they can make people fools .
Today the plans are expensive then any other network.
Note:-
This is according to me and area where I live but If you have any other good network present there then go for it but I have good network in our village, town and state.
