How much is the Apple care plan for an iPhone 8+ that’s only 7 months old

Hi Rmarks556,

Thanks for posting your question to the Apple Support Communities! As I understand you'd like to purchase AppleCare+ for your iPhone 8 Plus that's about 7 months old.

According to the public reference for AppleCare+ for iPhone AppleCare+ - iPhone - Apple you are only able to purchase AppleCare+ within the first 60 days of the original purchase date.

Please respond if you have any further questions.
