Has BSNL scrapped its Unlimited Prepaid schemes ?

I went through the bsnl.co.in link for prepaid Broadband but couldn't find any mention of Unlimited plans in there.Has it been scrapped ?Can a postpaid customer apply for a prepaid account simultaneously ? I already have the modem purchased and dont need any further "installation".In such a case how much shall I have to pay if I am opting for prepaid plans ?Thanks for looking ...

Seems so.Their prepaid plans were already expensive.
