I've been monitoring the reported data usage for a while now that I've reached my monthly limit. A few days ago I noticed that I am reaching my limit (it reporting that I had 50 MBs left) so I turned off cellular data on the iPhone so the data usage is 0 for the last couple of days. I checked last night and I still had 50 MBs left. I just checked again today and now I'm 60 MBs over my limit?! How is this possible with data turned off on the phone for the last 2 days?
