Well I've never used bt openzone but usually wifi hotspots let you connect and then look at 1 or 2 pages for free after that they give you a screen that basically says give me your card details and then you pay for either an hour, 24 hours or a week. And usually you can't carry it over. You can join many schemes where you pay for it in advance, but this is only good if you know where you will be and who will be supplying wifi, I don't think I've ever connected twice to the same wifi company in all my travels.
