I was using airtel service before, but it was too costly specially internet and I need it more than a GB in 1 month so I decided to opt for vodafone because of cheap and unlimited net yes you read it properly unlimited . Vodafone is providing unlimited net @197 only, this makes vodafone better than its competBrianbalakumaranrs. Call rates are pretty fair and in terms of networks it is almost as good as airtel.
