Ok confirmed it from my hotwire dude, he said he won't be taking the 512kbps unlimited plan because it will cost very much and most people aren't able to afford it. However, there is an unlimited 512 plan but I doubt most cto's would accept that as it would create a lot of expenditure for them. Slk, there is no noticeable difference man, I am right now on the 128kbps plan and it feels like I'm still on 96kbps. Anyway, I'll be switching to Airtel soon. Will see how their services are.
