Updating an iPhone 12 Pro:

A. Use a Computer to Update:

Have no Computer? Ask someone else if you may use their computer to do so, with them at your side while performing this.  See my User Tip: Update your iPhone Using a Computer - User Tip

or…

B. Update Over Cellular:

You can only update over Cellular using an

iPhone 12 or later with 5G. So, updating over Cellular may or may not be an option.

See my User Tip: Use an iPhone 12 or later, that is using 5G, in order to update over Cellular - User Tip

As shown in your screenshot: you will need to connect to a WiFi network to complete the update.

You are welcome. Good luck.
