I happened to glance down at my phone a few minutes ago and saw that apps were updating. I'm never connected to wifi when I'm at work. I fired up the App Store App, saw I had 17 pending updates. As I'm typing this it's down to 2. I confirmed in Settings > iTunes & App Store that Use Cellular Data is off. So... why did this happen? How can I prevent it from happening in the future? I'm on AT&T. Is there a way to see how much data I used between X & Y time today? If this was an isolated incident I'm not worried about my data, but if this is happening all the time then yeah, I might be in jeopardy of running though my data plan.
Update:
I have an iPhone 7+ and am running iOS 10.3.1
