Thanks for the information provided. Its much appreciated.
I am currently, using airtel 8 Mbps 80 GB FUP, threafter, 512kbps. My limit gets over in just a couple of days and I'm stuck with 512kbps for the rest of the month.
So, after seeing this plan from reliance, I contacted airtel and requested for cancellation of my broadband and they offered me another plan with 8 Mbps 300GB FUP for Rs. 3000 per month.
When I told them that Reliance is offering unlimited with no FUP at 1099, they answered, its not possible and started to read out TRAI (Telecom Authority) rules.
I think I will take the reliance connection and use it for a month, and if satisfied will cancel my airtel connection. I will have to pay extra for airtel but will be on the safer side if reliance does not work as promised.
Further, I have read on other forums, that whenever reliance releases some blockbusters, they block most of the torrent/filesharing sites for 3-4 weeks. So one will have a downtime for a month or so.
