I am using airtel service last one five year and this service is very best all over product and airtel is the best network in now a days.its signal is nearly high in almost all over the India. The best in airtel network is the internet speed is excellent when compare to other networks and it’s has 4g network now.its voice clearly is great while using voice calling. So I will use this network life time but airtel recharge is very high rupee if recharge will short rupee then customer will use airtel service large and large so over all airtel service my experiance is best service this time.
