```

## Overview

Functionality provided by the `activate` schema API is only available on iPhone in Japan and requires the <doc://com.apple.documentation/documentation/BundleResources/Entitlements/com.apple.developer.side-button-access.allow> entitlement. During development, install your provisioning profile on your iPhone test device to test the functionality. For a production device, the country or region of your Apple Account must be set to Japan, and you must physically be located in Japan.
