I experienced that airtel is a good service provider. Which is good for everyone. It has a 10 to 50 million people across over the india connection. And iy having a connection across 23 country. Its connection comes across urban as well as rural areas but coming to rate charges its charge is so high which is too bad and for internet it provide high amount for 1gb charge 248. But so how when the offers comes the rate decrease. And the voice calling is also high 1 min calling the rate cahrge is in local is 60 paise and STD 1.20 PAISE which is also too high. But it does matter when comes to the connectivity. So overall I would say that it is a good service provider.
