I am using airtel network from years its network is the best available at all the places but its call and data charges are the highest. They are increasing charges day by day and if there is any occasion they cancel all the add on packs.
Now a days we all have smartphones which we use for internet, calls, and sms which are all costly from this network.
The data charges should be reduced so that we all can use this network.
I do not recommend using this network, you can go for others there are many networks which offer fair plans.
Thank you
