please advise how can i update the IOS via mobile data?
iPhone 12, iOS 14
If you have a 5G signal on your iPhone 12 you can update it that way.
If that's not working, you can update it on a computer or if you don't have access to one you can go to an Apple store and they will let you use one of theirs.
The page you came from will have all the information you need on how to update.
