iPhone Ultra Could Face Delayed China Launch Over eSIM Issues


Apple’s first foldable iPhone could be heading toward a more complicated launch in China. The device, currently rumored to be called the iPhone Ultra, is expected to use an eSIM-only design, but reports suggest Apple is still dealing with challenges surrounding eSIM activation, replacement and transfers in the Chinese market.

That could push the Chinese release behind launches in other regions, adding another hurdle for a device that is already expected to have limited availability when it first arrives.

iPhone Ultra May Be Delayed in China

The issue is not entirely new for Apple. The company moved to eSIM-only iPhones in the US with the iPhone 15 series, and the transition was relatively smooth. China has proved more complicated, however, with Apple's eSIM-only iPhone Air also experiencing delays before its local launch because of compliance requirements.

Now, Apple could be facing a similar situation with the iPhone Ultra. According to a report from Weibo account Instant Digital, the current eSIM experience in China still has problems involving activation, replacement and transferring service between devices. Since the foldable is expected to become Apple's second eSIM-only iPhone sold in the country, those limitations could affect its launch schedule.

Why Is the iPhone Ultra eSIM-Only?

The decision appears to be closely connected to the foldable's design. Like the ultra-thin iPhone Air, the iPhone Ultra is expected to make extensive use of its limited internal space, leaving less room for components such as a physical SIM tray.

Removing the SIM slot can give manufacturers more flexibility when designing extremely thin smartphones, but it also makes carrier compatibility and eSIM management more important. That becomes particularly noticeable when users move from an existing phone to a new device and need to activate their mobile service again.

The iPhone 18 Pro and iPhone 18 Pro Max are reportedly taking a different approach. Both models are expected to retain a physical SIM and eSIM combination, making them less dependent on the same eSIM infrastructure.

Moving Data to an eSIM-Only iPhone

For anyone upgrading to a new iPhone, mobile service is only one part of the transition. There is also the question of moving years of photos, contacts, messages, videos and app data to the new device. If you plan to copy my phone data to a new iPhone, having a straightforward transfer method can make the setup considerably easier.

Smart Transfer can help simplify that broader transition by bringing device-to-device transfers into one place. Whether you need an anywhere file transfer solution for moving selected files or want to handle a WhatsApp backup transfer, the goal is to make switching devices less of a project. This can be especially useful when a new phone introduces a different setup process, such as an eSIM-only design.

iPhone 18 Pro Models Could Have an Easier Setup

The reported SIM configuration gives the iPhone 18 Pro and Pro Max a potential advantage for users who prefer more flexibility. With physical SIM and eSIM support expected, buyers may have more options when activating their phones or changing carriers.

The iPhone Ultra, by comparison, could require users in China to rely entirely on supported eSIM services. If Apple's existing eSIM infrastructure still has limitations around activation and transfers, that could make the foldable more complicated to launch than its conventional counterparts.

Availability Could Be Another Challenge

Regulatory and eSIM concerns may not be the only factors affecting the iPhone Ultra's availability. Earlier reports have suggested that Apple could initially limit the foldable's launch to the US before expanding into additional markets.

That would make the iPhone Ultra's first release considerably more selective than a typical iPhone launch. Supply constraints combined with regional eSIM requirements could mean that some buyers have to wait longer than expected to get their hands on Apple's first foldable.

What Happens Next?

Apple is expected to unveil the iPhone 18 Pro, iPhone 18 Pro Max and iPhone Ultra soon, with pre-orders reportedly scheduled to follow shortly afterward. The company's launch event should provide much clearer information about pricing, availability and the final SIM configuration.

For Chinese buyers, however, the most important detail may be when the iPhone Ultra actually becomes available locally. If eSIM activation and transfer issues remain unresolved, Apple could stagger the launch rather than release the foldable worldwide at the same time.

The iPhone Ultra may be Apple's most ambitious iPhone yet, but its success will depend on more than its hardware. Before the foldable can reach customers everywhere, Apple needs to make sure the everyday experience of owning one is just as smooth as the device itself.
