I love airtel broadband not because of the popularity but because of the services offered by the Airtel.Number one customer services provided by Airtel.I am using airtel since last 6 years and my airtel Plan is 512 Mbps I always get same speed at every time .This is one of most reliable broadband service in India.
Speed of ISP is awesome some broadband connection speed vary time to time but airtel broadband speed same all the time.I love the customer support provided by Airtel because whenever we feel chaos in the speed they here our complaint immediately and solve the problem same day.I think it can be costly for some persons but they never compromise with their quality.
