My experience with airtel has been really very amazing till date.I am a prolonged customer of airtel for about 7 years and I have no regrets regarding the same.The best in network, the best in service, the best is customer satisfaction and an overall family package.Airtel has the best network coverage all over in india wheather it be metro cities or wheather it be the remote areas.They have the best customer support who are available for you whenever you are in need.May be it would be a bit expensive than other operators bit its completely worth it.
