This is something that's been frustrating me for a while now. I have a huge 20GB data plan. I also have rollover data, so most months I have 30-35GB of data available. Yet iOS doesn't allow me to do these things over cellular: - Download software updates - iCloud backups - Upload photos to iCloud Photo Library - Update apps over a certain size - Restore your phone from an iCloud backup Is there a reason they absolutely refuse to let you do these things over cellular? Even something as simple as requiring manual initiation of the backup or photo upload, with a warning telling you it will use your data plan, will make things so much better. I'm often on vacation with no good WiFi around for a few days; I'd love to be able to back up my photos and phone during that time! Isn't it time Apple allowed you to override these restrictions?
