The service provided by the airtel mobile operator is GOOD .
BUT the thing is you have to pay high price compared to some other providers.
You can have your custom plan according to your usage which is thing is very nice.Costumer support is very good compared with other providers .
Lets talk about some problems unlike voice calls the internet speed is not good as fr as I have experienced the internet speed is not good as they show in their ads.So if you want to use internet try some other operator I suggest.
But if you are looking for a networks provider whose service is wider and no call drops etc.then its a best choice.
