My husband and I have shared 2 gigs of data for over a year and have never come close to using even 50% All of a sudden, we are at 90% of our usage and nothing has changed. We use WiFi at home and at work. I looked at our data usage online and the time stamp shows data accruing when we are asleep at home! Verizon had no explanation, one service rep put me on hold to check it out and left me on hold for over 25 minutes. He never came back and I called again. The other service rep had me reset my networks. What's going on Verizon? I see lots of other people are having this issue.
