Airtel is providing very good mobile service across the country. Once I have visited to a very interior village of Jagatsighpur, Odisha, where I didn’t find any mobile network except Airtel. The charges are nominal and plans for data and calls are economical.
Moreover they are the only company to offer fast 4g service in India in same charges of 3g. I have never face any problems like call drop or signal lost since my usage of Airtel Mobile from last three years. Now I am planning to change my number to Airtel by Mobile Number Portability.
