In a significant shift, Apple has confirmed that the new iPhone Air will operate exclusively on eSIM technology worldwide. This ultra-thin model, measuring just 5.6mm in thickness, eliminates the traditional physical SIM card slot entirely, marking a bold step toward a more streamlined iPhone ecosystem.
The announcement came during yesterday’s Apple Event, where the iPhone 17 series was introduced alongside enhancements in performance and battery life. The iPhone Air stands out not only for its slim profile but also for prioritizing digital SIM capabilities, which Apple first experimented with in the U.S. market years ago. By going eSIM-only, the company aims to reduce hardware complexity and potentially improve internal space allocation for other components, such as a larger battery promising up to 27 hours of video playback.
eSIM, or embedded SIM, is a digital alternative to physical SIM cards that allows users to activate cellular plans directly through their device without needing to insert or swap cards. This technology has been standard in iPhones sold in the United States since the iPhone 14, but the iPhone Air extends this approach to all markets.
One notable aspect of this rollout is its availability in China. Contrary to earlier speculation that eSIM-only devices might face barriers there, the iPhone Air will be supported through carriers like China Unicom, enabling users to activate plans seamlessly. Apple has addressed potential concerns by confirming compatibility with local regulations, though overseas eSIM activations may be restricted for Chinese models to comply with tightened controls on the technology.
For global users, the transition to eSIM-only means greater convenience in managing multiple plans—ideal for frequent travelers who can switch carriers digitally. However, it may pose challenges for those in areas with limited eSIM support or who prefer the simplicity of physical cards. Apple assures that setup remains straightforward via the Settings app, and most major carriers worldwide now offer eSIM options.
