so i finally moved from airtel to bsnl thinking that after fair usage policy in bsnl the speed will remain 512kbps.plan: 750UL i regret my decision. till 1mbps the surfing and downloading is fine( download speed is around 180kBps and upload 100kBps)... pings are much better than airtel. so after using 6gb data... speed dropped down to 512kbps ( FUP ) but speed is no where near 512kbps.. its just fluctuates between 300kbps to 500kbps all the time.. pings and latency also increased a bit.:angry::angry:strange thing is that the upload speed is still 100KBps , they are just capping download speed. 😛so conclusion is that as soon as you hit FUP the downloading experience will be same as that of airtel ( 256 kbps FUP)
