We just got a couple iPhone 8s and I noticed our daily allotted bandwidth (475 MB) disappearing after we had set them up. I had disabled automatic updates from settings > my name > iTunes & App Store. On the other phone I noticed that apps were downloaded so I thought that was the reason our bandwidth was used up. But with my phone I am not downloading any apps from the cloud or manually downloading a software update. I have also removed widgets other than Calendar, Reminder and Up Next. Still, our bandwidth is being used up until I turn off the wifi on my phone. My phone is the only one connected to the Airport Express and I have set up the other iPhone to connect during free download hours only. Is there another setting that I am missing in iOS 11.2.5 that I need to disable to keep the phone from downloading?
