Cell Phone games

[Scorpion]

I've downloaded a couple of games from this website www.mobilerated.com And for some of the games it says [ads] next to them. And it says it has to download ads from somewhere to play the game. I don't have a internet connection on my phone, when I try to connect it says connection failure. But the games still work.

So I was wondering, are the games somehow downloading the ads from the internet and will I still be charged for it even though I don't have internet connection on my cell?
