Apple Intelligence is still not accessible for iPhones and devices purchased in mainland China, despite its global rollout. Users from outside China who visit the mainland also face restrictions. While iOS 18.4 has made the feature available in Europe, mainland China continues to be excluded due to local regulations. Devices bought from regions like Taiwan or Hong Kong can use Apple Intelligence if supported. Users will regain access upon leaving China, but residents with foreign-bought devices will remain unable to utilize the AI technology. Compatibility is limited to newer models, further complicating access.
