Selling an iPhone does not always mean its AppleCare coverage simply disappears, but what happens depends on the type of plan and how it is paid for.
Some AppleCare plans can be transferred to a new owner, while plans billed on a recurring basis may be tied more closely to the original purchaser or Apple Account. AppleCare One works differently again because devices are managed as part of a multi-device subscription.
Before selling an iPhone, check its current coverage under Settings > General > AppleCare & Warranty and review the plan details associated with your account.
If the coverage is eligible for transfer, Apple may require information about the device, proof of purchase and details for the new owner. The exact process can vary by country and plan.
For AppleCare One, removing a sold device from your plan is important so your coverage accurately reflects the products you still own. Eligible replacement products can then be managed through the AppleCare & Warranty settings.
Do not advertise an iPhone as including transferable AppleCare until you have checked the terms for that specific plan. Confirming the coverage first avoids promising the buyer protection that may not follow the device.
