On the phone with AT&T now trying to figure out why his phone would use 189MB (yes MB) of data at night while on wifi. (yes, I know there are delays, but still). I just got an overage alert on his phone and checked the bill and was stunned. AT&T credited me $30. while they try to figure out what's going on. And yes, the usual suspects (diagnostic data etc. are off). And, no, he typically uses between 50 and 75mb a month, so it's not normal even with reporting delays. And having it appear as ONE transfer is not normal.
