Airtel is my most favorite mobile operator service. I started my internet from Airtel. By 3 years I have used the airtel service continuously. Airtel’s Internet speed is very good, compared to other networks. Airtel’s network works for 24 hours. Airtel’s Customer service is so fast and so active. Employees are immediately reduced when there is a fault in the Airtel network. Its internet balance charge so Costly but speed provide is so high.
My own experience that Airtel is best mobile operator comoany.
