Why backup and software updates required WiFi connection this facility should be Available for iPhone itself data service
iPhone 6s, iOS 11.0.3
Not everyone (probably most people) has an unlimited data plan. If the software allowed large file transfers (such as those that involved the backup of the device), the fees for data could become extremely large. They would eat thru most data plans in a couple of days.
That is the reasoning behind the software not backing up or app updates over cellular.
If you think there should be an option to choose between Wi-Fi and cellular, send Apple feedback. They won't answer, but at least will know there is a problem or a suggestion for change. If enough people send feedback, it may get the problem/suggested change solved sooner.
