Apple Intelligence continues to be inaccessible for iPhones and devices purchased in mainland China, despite the rollout of iOS 18.4. Users who bought their devices outside China but are currently in the mainland also cannot access this feature. While regions like Taiwan and Hong Kong can utilize Apple Intelligence, mainland users remain excluded due to local regulations. The global rollout of Apple Intelligence has faced delays in specific regions, highlighting ongoing compliance challenges. Users will regain access once they leave the mainland, but restrictions persist for residents.
