AppleCare
Hello
I’m about to order the iPhone 10 today and I was wondering if I’m buying the AppleCare for how long does it last
And if I’m not buying it today do I still can purchase it in the future?
AFAIK you now have 60 days after purchase to enroll in Apple Care (previously it was pro-rated as an option if you were still within the original warranty). You are eligible provided you bought from an Apple authorized reseller. If you buy from Amazon, eBay, etc then your warranty had already started with the original purchase by the reseller.
Apple care is valid for 3 years, both phone and hardware support and two discounts on accidental damage repairs.
