I notice that, when I make calls on the S5 from my house, the Notification Bar shows WiFi active but does not show 4G, 3G, LTE or any other mobile network active. Is it possible that the calls are being made via WiFi?
I also notice no data is being used for those calls. I've had the phone now for a week and have been using it almost 8 hours per day. I only used it outside of the house for a couple of text messages.
My data usage at the ATT web site shows only 58 Mb used of my 2 Gb monthly plan. It appears WiFi is absorbing almost all my usage since I have unlimited data available using WiFi.
