No! Well, AppleCare+ plans for iPhone and iPad purchased in the United States and Canada are only valid in the United States and Canada, but other Apple devices (Apple Watch, Mac, iPod, Apple TV, and Apple displays) provide global coverage.

Much like Apple handles support calls over the phone, soon only customers within their warranty period will be able to access online chat support through getsupport.apple.com for free. For others, Apple will charge what it refers to as a “pay per incident” fee or require the purchase of an extended warranty through AppleCare. Previously all online support chat features were available for free to users worldwide. Some users might have noticed back in August when Apple revamped its support sites that it started listing a $19.99 per incident fee for chat support. However, up until now AppleCare hasn’t actually been charging users to access the feature.
