How to renew expired AppleCare+ coverage?

If you are outside the renewal window, no.

If you paid upfront for an AppleCare+ plan, you might be able to purchase new coverage within 45 days after your original coverage ends. In China mainland, you might be able to continue coverage within 30 days of the end date of your coverage. Not all products and buying options are available in all countries or regions.

I’m confused. You can’t get AppleCare for a phone until you own it, and you can’t transfer AppleCare to a new phone, you must purchase a new AppleCare plan for the new iPhone.
