I am using Airtel network since 11 years and it is a very nice network because the plans, offers and service of airtel is very good.
Mostly I use this network for calling. Calling rates of this network are affordable.I am not using the mobile data of this network because in our village there is no network for 3 G or 4G Internet.
But 2G Internet speed is nice.
Best plan of the airtel is Airtel money.
I use this wallet for
mobile recharge
DTH recharge
send or withdraw money
Pay at shop
Book tickets
Pay bills
and much more things.
Just dial* 400#
For any services just dial * 121#
I like this network.
So I recommend you to buy Airtel.
