Will AppleCare One cover a non-US iPhone, even if you live in the US?

If you have a non-US iPhone set to the US region and live in the US, you will have to call Apple Support in order to get AppleCare One coverage. My Canadian iPhone 16 Pro Max tells me I need to contact Apple for an in-store or remote assessment in order to determine eligibility. I already have AppleCare+ on the device and my other devices that have AppleCare+ can be transferred to AppleCare One, so my gut tells me the error is because my model is not a US model. As for my iPhone 13 mini, the battery health is at 79%, so that doesn’t qualify.

Instead of calling Apple, I decided to go to my nearest Apple Store to do an in-store assessment, but the Genius (not trying to be sarcastic) wasn’t able to do the right diagnostic test to make it AppleCare One eligible. I wasn’t going to switch from my current AppleCare+ to AppleCare One, but I just wanted to see if it would even be possible to do on a non-US device.

They told me to call Apple Support since they have more robust remote diagnostic tools, so we will see how that goes in the future.
