Hi I Live in Bangalore and i have been using AirTel from almost 2 years now.

I had 64kbps unlimited plan earlier then 128kbps unlimited plan & now i use 256kbps unlimited plan.
Till Date i have never faced problems with Airtel.
I should say its that best service provider in the country.

They have very nice service.

They even collect your bill from home for no extra charge.

If some time u face any problem it will be repaired in less then 24 hours.

I have never had any problem with the speed or connectivity.

I had problem with router once which was replaced by AirTel the next day for no extra cost.

I would suggest everyone to get AirTel connection for the service & real broadband experience.
