WiFi vs. Cellular Use
I have Cellular Data turned on, but the phone is almost always connected to inhome Wifi. I just reviewed my Cellular data use "for the period" and saw "11.3 GB." The list of users of the cellular data is long and includes apps that a) I haven't operated in months or b) I only use at home when on WiFi. I am retired and out of my house connected to AT&T perhaps 3 hours per week, only just carrying the phone unused 95% of the time and using it only to send or answer calls the other 5%.
My plan covers !GB, but I never get a bill for exceeding that. There is something I am not understanding here.
