Airtel or Airtel Bharti at one time one of the best service provider in India every one appreciate it. BUT this service seems to turn very worst in every angle like 4g, 3g charges, Call drop in many parts, Very high charges.In the era of competition, Airtel should maintain its position by providing best service to its customers but they have failed to do so.So it's better not to choose Airtel as your telecom operator.
