Apple Intelligence continues to be inaccessible for devices purchased within mainland China, affecting iPhone users both locally and abroad. Despite the rollout of iOS 18.4, which granted access to Europe, users in mainland China still face restrictions due to local regulations. Those who bought iPhones outside China but are visiting the mainland also cannot utilize Apple Intelligence. Only devices purchased from Taiwan, Hong Kong, and Macau are eligible for this feature. Users can access the service again once they leave the mainland, highlighting ongoing issues with global availability.
