Can you tell me how it differs from internet usage in the states to foreign countries(South Africa) I have a service now that claims I use over 1G a day...this last month I was charged for over 50G. I use FB and yahoo email. I do play slots/bingo online...can that increase the usage to this high extremes. We have no other options here but feel that something is calculated differently than services in the states. We do not dl movies but on rare occasion use our roku. I am not tech savy..know enough to use it!
