I have been using Airtel Broadband more than 1.5 years in Bengaluru. I don’t want to be biased while writing the review.
Believe me or not, I have never had a single issue of disconnection or broadband speed in the last 1.5 years. Its working awesome as always.From my friends, I always used to hear that their broadband from different ISP providers always has the problems and disconnection issue. So later they also moved to Airtel and now they are happy. Any support/service also done by Airtel at the moment you raise the request.
Airtel Broadband is simply awesome. Go for it and you wont regret.
