Apple's official Apple Store website was updated today, adjusting the release time of the iPhone Air to 'Release information to be updated subsequently,' with all models requiring approval before release. The official website indicates that the iPhone Air only supports eSIM activation for carrier networks and does not support physical SIM cards. Users need to select carriers and service plans that support eSIM. China Mobile, China Telecom, and China Unicom will provide eSIM support, with specific timelines depending on regulatory approvals. Users are advised to contact their carriers to confirm eSIM support availability.
