Try Updating Using a Computer:

Stop the current updating, and then try this once more, but this time use a computer to do so. If you could not update directly from your iPhone, then try using your computer (PC or Mac)

Use a PC or a Mac to Update it:

1. Back Up First: Make a backup of your device using iCloud or your computer. That way you can have something to restore you iPhone from, should anything go wrong with the update installation.

2. Then, Update Using Links:

Disable Cellular when updating on the iPhone.

• On the iPhone itself: Update your iPhone, iPad, or iPod Touch - Apple Support
• From a Mac: Update Software on iOS Devices in iTunes on Mac - Apple Support
• From a PC: Update Software on iOS and iPadOS Devices in iTunes on PC - Apple Support

Important: Be sure to back up your iPhone, that way you have something to restore your iPhone from, should anything go wrong with the update.
