Intelligence is not available on my iPhone from Hong Kong
My iPhone 15 Pro is from Hong Kong (China). I am outside of China and Asia in general. I have never been to China myself and the iPhone was activated in another country. And it is not the EU.
My iPhone's language, Siri and region settings are changed to US English. Updated to iOS 18.1. But Apple Intelligence doesn't show up in the Siri settings.
