We are using Act since 6month in our office. Act fibernet is good ISP in Bangalore and Beam in Hyderabad too.
Very popular and provides good speed.Speed: 100mbps upload as well as download and it gives around 95mbps speed.
I recommend both home users and office user to have it. And provides very low price too.Customer service is also good and they resolved issue in next working day itself.Personally I suggest to go with it.
