ACT formerly known as Beam Telecom is the best broadband service in Hyderabad.
Their service is excellent when compared to other broadband services like BSNL, RVR etc.Now they doubled their speeds for the same cost which they used to offer.
The only drawback of ACT is their FUP(Fair Usage Policy) Limit which is less.The FUP gets completed very fastly within 10-15 days.After FUP they give 1/10 original speed, which is low.They are the only broadband that offer higher speeds at low cost.I would recommend you to take ACT Broadband as your ISP because it is the best ISP.
