We have been struggling with data overage for the past 2 years. We have checked our acctivities and (some, but not most) can be attributated to this. However our data usage is constantly extremly high. We have switched devices several times. Our original device, the first year was fine, since then it has been terrible. I have spent numerous hours and $ attempting to fix this problem, no one has an answer. Has anyone else run into this? Have you found a solution?
