I noticed this last month, called AT&T about it but nothing was really figured out. When I looked at the data usage for my iPad, it seemed a lot higher than what is used. I take it with me when I got out sometimes, surf the web, e-mail and Facebook sometimes and once in a while use a navigation program but it's not like I sit and watch movies or programs. My kids will watch shows once in awhile but that's usually only about 30 minutes at a time, maybe 2-3 times while we are out some weeks (if that). This month I was also thinking that usage was high. Especially for the amount that it was used outside the house. I watch my iPhone usage monthly. That gets a lot of use and I've only broken 3GB once and that was really trying. I checked my iPad usage yesterday a couple of days ago and saw that it was around 21xx. Ok, plenty of data left. I checked it yesterday morning and saw that it was around 2500. Statement closes on the 27th so I'm good. Today I get a message that said I was at 27xx. Then a few hours later I received one that say it went over my 3GB allowance for the month. How did that happen? So I checked my account to looked at data use for the last few days. Today, my kids used it from about 3:20 to about 4:00 at the latest while we were out (watching a show). We were home the rest of the time and they were using it in the house. Between 4:00 and 5:15, I'm showing 481MB of use. It was on WiFi! Also, at 1:37 today it showed 97 MB of use. I was in the shower and the iPad didn't leave the house until about 2:05. Looking at yesterday, there was 112KB of use while I was home and the day before that there was a ton of data transfers while I was home and on WiFi. Like at 12:43am, while I was sleeping, while I was out and the iPad was home, ect, ect. Has anyone experienced this or have any ideas? I called AT&T but they were closed so I'm going to call tomorrow. My phone gets a lot more use both at home and outside of the home and it doesn't come close to using the data that the iPad is showing.
