I have the Boost Mobile unlimited data plan. (The one for $50) My phone only has game demos, though. When I click 'Buy Full Version' it redirects me to a web page and instantly a menu pops up saying, "The content is not currently not on your device." And then it has two options, 'Get content' and 'Cancel'. It didn't even ask me for a method of payment. Would the cost get added to my next month's bill? Or is it for some reason free?
