Updating an iPhone 5s without WiFi:

Do so using Ethernet on a computer.

Use my User Tip:  Update your iPhone Using a Computer - User Tip

Back Up First:

IMPORTANT: If you have an option to update, however, then be certain you backup your iPhone first. That way, you will have something to restore your iPhone from should anything go wrong with the update.

It’s actually quite easy to update over cellular on an iPhone 5s, though it does require the assistance of your cellular carrier. You’ll need a device known as a MiFi or JetPack, which is a cellular-to-Wi-Fi gateway. With that gateway, you have Wi-Fi using your cellular data. You can also use this for iCloud backups.

You will need a cellular plan with sufficient cellular data for the update, as those updates are often not small. Or for iCloud Backups. Otherwise, this approach gets Really Expensive.

iPhone 5s cannot be updated past iOS 12. The most recent update is iOS 12.5.6.

Not possible to update the iPhone 5s without Wi-Fi.

Take the phone down to the coffee place and log onto the WiFi there.
