Cellular Data not working
My cellular data is not working at all. I looked at settings and it just says that “An update is required to use cellular data on this iPhone”. I’ve already updated to the latest version and it solved the problem but then it said this again. I’ve turned my phone on and off multiple times. I’ve tried removing my sim card and putting it back in. I’ve tried turning on airplane mode and then turning it off. I’ve tried everything I can think of and nothing worked and I’ve had this problem for a week now. Please help!
iPhone 12 Pro Max, iOS 15
