I’m using iPhone 15 Plus and until now, I can’t upgrade into iOS 18. It is available on my software update but whenever I try to update, there’s a note that keeps on appearing and it says, “Software update failed… an error occurred downloading iOS 18.” Can anyone help me? It would be appreciated.

If your iPhone or iPad won't update - Apple Support
