How can I add AppleCare to iPhone 15 months after switching from iPhone 12?

I had two iPhones on my account. The phone I used I had AppleCare on that was an iPhone 12. My adult son had an iPhone 15. I ended up paying his phone off through the AT&T store. I switched to using it since my son moved, and was no longer using. I sold my old phone months ago, but forgot to switch coverage to the new phone. How can I get coverage on this new phone even though I’ve already had it for months.

Original Title: Coverage was on the wrong phone.

Sorry, but Apple is very firm on this. Once purchased brand new, you have 60 days to purchase an AppleCare+ Plan. Since one was not purchased within that timeframe, it's too late to buy one now. You can often buy a plan from your carrier, but it won't be the same as AppleCare+ from Apple.

If it has been more than 60 days since the original purchase date of the iPhone 15, and it has not been on an AppleCare+ plan, I don’t believe there is any way to get AppleCsre+ for it now.

Probably a lot more than you wanted to know, but here's the official Apple document:

Extend your AppleCare+ coverage - Apple Support

Just about every example begins with the phrase "If you paid upfront for AppleCare+......"
