I just upgraded from a 4gig shared plan to 6. I never went over the previous plan, but now that I have more data, I've gone over. There is no difference in how we are using our phones, and when I look at the data usage for each phone on the plan (there are 4, all different phones) the times don't make sense - in some cases it appears that data is being used in the early morning hours when we are sleeping. In other cases, the are duplicate entries for the same dates and times. What the hell is going on? I don't even dare try to call Verizon customer service b/c I know I'll be on the phone with them for hours with no resolution or explanation that makes sens to me (it makes perfect sense to them, however). Anyone else experienced this?
