In my settings under Cellular Data, I can only see FaceTime and Wallet I can not turn cellular data on or off for any other individual apps on my phone. I am on the latest IOS version 11.3.1. I have contacted Apple several times, but they do not get back to me with any solution. They just ask for logs and it has been almost 2 months of the run around. When I wipe the phone and restore from my backup the problem reappears. The only solution to date is to wipe the phone and set up as new, but I don’t want to lose any data. I see posts about the issue dating back to iOS 7. My data plan is being eaten up in the background and I have no way of stopping it. Has anyone ever experienced and solved this issue without wiping their phone? Thanks.
