I am from Hyderabad and most IT companies in Hyderabad use Beam( Now act fibre).
Speed: Internet speed is probably the best you get and plans are also good. But the problem is it is fine as long as it works. But if there is disconnection like cable cut etc and You complain them, it may take forever to rectify the problem. This is only for home users. It has been four months since I am using it. There is no problem with speed but support is really bad. My internet cable was bitten by a dog in the neighbouring building as the cable passes through their building to the box. I had to call twice every day for 5-6 days and then only it was rectified.
