MacBook Air M4 AppleCare+ monthly plan: India to Italy

I don't know if there is a simple or happy answer to your question but I do know that if you change country settings on your account (as you should when you move to reside in a different country) that you have to cancel all subscriptions in the old country.

Note that this whole topic may be moot: Apple's warranty restrictions may preclude getting service on a device in another country. Legal - Mac Warranty ROW - Apple "Apple may restrict warranty service for hardware products to the country or region where Apple or its Authorized Resellers originally sold the device."

If you wish, you can contact Apple about this. This support article has various country telephone numbers for contacting Apple for support and service ➔ Contact Apple Support - Apple Support Scroll down to “Connect with live support”. If your country is not in the list, do to the “Other countries” entry at the end of the list. Not every country has telephone support, and phone numbers may only work when calling from the same country.

If you do contact them, let us know what they say.
