Is there any BSNL BB plan having a monthly rental of Rs. 900 with 4 Mbps connectivity speed that never reduces to something lower after crossing any certain limit? I am asking this because, I'm am not exactly sure which plan I actually have ( ) ... I just answered "900 Unlimited" when I was asked for the plan which I wanted to opt by BSNL guys while obtaining the connection. I saw on BSNL website about the "900 ULD"(<--pl. note) -- it was written: "4Mbps upto 8 GB, then 256Kbps onwards". I received a small form filled by BSNL guys ... the plan was mentioned as "900ULFC"(<--pl. note again). When I asked about that speed limit from the BSNL guys who came for modem installation and setup, they said there is no such speed limit, they said speed would remain 4Mbps only, no reduction after any limit. But I don't trust at all about what he said. Is there really any such plan which the BSNL guy mentioned of?
