The iPhone 6 I'm using is still eating through wireless data even though I toggled the "Cellular Data" switch off. New phone, set up from scratch. Steps I've taken: Disabled Cellular Data Disabled LTE Voice/Data preferences Disabled iCloud Disabled App Store auto updates Disabled Individual Apps Disabled Background Tasks WiFi enabled Latest version of iOS The 2gb plan I have with AT&T has already run over. I checked the account and it's still pinging a server and downloading 20mb chunks of data whenever it wants. What gives?
