I think, competition has forced the providers with these plans. I was using Beam cable internet at Hyderabad. I was on 256 kbps UL earlier. it was changed to 768 kbps (thrice the speed) without extra charge. Now I have FUP of 30 GB on 768 Kbps. and the speed changes back to 256 kbps till end of the month. They have changed all the plans accordingly. 128 kbps to 256 kbps, 256 to 768, 512 to 1Mbps, 1Mbps to 4Mbps. I think even BSNL have upgraded the plans.
