from my experience using it, the only person that gets charged is the person that gets the text message sent to them from the site (unless of course they have unlimited text messages, etc)
Well this helps me out a lot when i'm offshore working, because my girlfriend at home doesn't have the internet, and my cell phone doesn't work out here... You can send and receive text messages, no cost..
