Unlimited Broadband With No Fup

I maybe trying a long shot, but I thought it would be worth a try asking on the forum.
I am looking for a new broadband connection which is truly unlimited and has no FUP. With the FUP limit I think the chances may be low, but even if the limit is somewhere near 100GB it would be good as I can not stand slow speeds, especially when there is some important work to be done online.
I don't think PTCL is a suitable choice as they have a lot of mess ups, and anything else other than PTCL.
My location is for the next one year will be Lahore otherwise I am from Karachi, so when I need a connection in Karachi I will create another thread for that.
