I am using airtel since 3 years now and there was not a single time this service tried to disappoint me.EI got this simcard at college festival when they had friends group thing going on.verytime when I need to make urgent call there wont be any network.
Especially when I am travelling in mumbai trains this network will vanish.The internet plans are so useless and not worth the money.I never get 3G network at my place even if I subscribe 3G plan.I hate this network.The customer service is worst.They wont help you.They will keep giving some stupid alternate option.I will port my number to idea soon.I wont recommend this service to anyone.
