We just switched from 2 Palm Pixi smart phones where our data usage was under 500 MB per month. We now have Pantech Marauder phones and automated Verizon is telling us we are using data at a rate of 10 GB per month. Is there an app that is running that could be a data hog? We don't download movies or music or play interactive games, so I don't know why our usage could be so high. Or is there something wrong with the way Verizon is tracking our usage?
