It is said that the iPhone 17 will have an ultra-thin design and will not have a physical SIM card slot. Explanation of the full popularization of eSIM and the prospects of the Chinese market

With the continuous advancement of technology, eSIM (embedded SIM card) technology has gradually replaced physical SIM cards and become an important trend in the global smartphone market. Apple plans to further promote the popularization of eSIM in the iPhone 17 series to be launched in 2025, which may mark a major change in mobile phone communication technology. However, this change will open up more countries to popularize eSIM, but it also faces challenges in policies and consumer habits in certain markets, especially China.

According to reports, the iPhone 17 series will feature a slim and lightweight design, with the iPhone 17 Air being only 5-6 mm thick, which is thinner than the 7.8 mm of the iPhone 16 and the 8.25 mm of the iPhone 16 Pro. To achieve this design breakthrough, Apple made a number of compromises, including removing the physical SIM card slot , reducing the number of speakers, and reducing the battery capacity.

This means that the iPhone 17 is likely to become Apple’s first series of models that completely does not support physical SIM cards and will fully switch to eSIM technology. The features of eSIM not only make the internal design of the device more flexible, but also provide more functions, such as supporting up to 8 eSIMs, making it easier for users to switch networks, while improving security - even if the device is stolen, the eSIM cannot be easily removed.

eSIM offers many advantages to users and is rapidly gaining popularity in markets such as the United States:

1. Easy switching Telecom operators : Users can quickly change or add numbers through software without having to replace physical cards.
2. Higher security : Physical SIM cards can be easily removed or stolen, while eSIM technology avoids this risk.
3. Multi-SIM card management : One phone can manage multiple eSIMs at the same time, which is especially suitable for international travelers or business people.
4. Improve design space : After removing the physical card slot, the internal space of the phone can be used to improve other hardware performance, such as a larger battery or a more powerful cooling system.

At present, starting from iPhone 14, the US version of iPhone has fully switched to eSIM, and it is gradually becoming popular in markets such as the United Kingdom, France, and Japan. The launch of the iPhone 17 series may further promote this trend in more regions.

Although eSIM technology is rapidly being promoted around the world, the Chinese market faces significant challenges.

1. Policies and Real-Name Requirements <br>China implements a strict real-name system for mobile phones, and users must use a physical SIM card for identity verification. The technical characteristics of eSIM make it difficult to meet this policy requirement. At the same time, Chinese telecom operators currently do not generally support eSIM technology on smartphones, and only provide limited support in devices such as Apple Watch and iPad.
2. Market acceptance <br>Chinese consumers are deeply dependent on physical SIM cards. If the iPhone 17, which cancels the physical card slot, enters the market, it may not be widely accepted and may even affect sales performance.
3. Potential Solutions <br>Apple may need to launch a special version of the iPhone 17 for the Chinese market, retaining the physical SIM card slot, or cooperate with Chinese telecom operators to promote localized adaptation of eSIM technology.

Apple's plan to completely remove the physical SIM card slot in the iPhone 17 series is undoubtedly a key step in promoting the popularization of eSIM. For markets such as the United States and Europe, this will accelerate the popularization of eSIM and make it a standard configuration for smartphones. However, the particularity of the Chinese market makes this transition more uncertain.

If Apple can successfully promote the acceptance of eSIM technology in the Chinese market, it will help improve the maturity of the global eSIM ecosystem. However, in the short term, the technological and policy environment in the Chinese market may become the biggest challenge for iPhone 17. For Apple, how to balance global market demand and the particularities of the Chinese market will be the key to future development.
