Summary of Key Points
2025 marks a crucial milestone for the commercialization of eSIM phones in China: The three major telecom operators have received approval from the Ministry of Industry and Information Technology to conduct trials, and manufacturers such as Apple and Huawei have released eSIM-enabled phones, signaling the official entry of China into the eSIM phone era. However, the general awareness of eSIM is still low, and its adoption has been delayed in the past due to security concerns (such as fraud vulnerabilities). At the same time, the advent of AI has elevated eSIM from a simple communication module to a 2.0 version, transforming it into an identity carrier and information hub for AI devices. The industry needs to work together to address issues such as standardization and user experience optimization; the market potential is enormous, with projections indicating that by 2030, there will be 4.9 billion eSIM-enabled phones in use, accounting for a penetration rate of 55%.
I. Commercialization of eSIM Phones in China: Delayed but Finally Here
The rollout of eSIM phones in China has not been smooth. Operators attempted trials as early as 2017, but the process was abruptly halted in 2023 due to fraud issues—people were using fake identities to register large numbers of eSIM cards for telecom scams, causing significant regulatory challenges. It wasn't until October 2025 that the three major operators received approval for trials, and new models such as the Apple iPhone Air (the first eSIM-enabled iPhone in China), Huawei, and OPPO were released, finally breaking the ice. Now, the entire industry is enthusiastic, filling a long-awaited gap in the eSIM ecosystem.
II. User Profile of eSIM Phone Users: Young, Heavy Data Consumers; Market on the Brink of Explosive Growth
A senior executive from China Unicom provided insights into user demographics: 80% of users are under 40 years old, and nearly half opt for high-data-capacity plans (over 80GB), indicating a willingness to try new technologies and high data consumption. They predict that the domestic eSIM phone market will reach approximately 30 million units in 2026, with fewer shipments in the first half of the year, but mainstream brands will start including eSIM in their new products in the second half. Those considering buying a new phone should keep an eye out for these developments.
III. Many Benefits of eSIM, Yet Few People Are Aware
The advantages of eSIM are clear: For consumers, there's no need to visit service centers to swap cards, and phones can be designed to be thinner and more compact (without the need for a SIM slot). For operators, the process of connecting devices to the network is more digitalized, reducing costs. For phone manufacturers, it allows for more flexible hardware design. However, awareness is still low; most people and manufacturers only understand eSIM as a feature that eliminates the need for a physical SIM card. To make eSIM widely adopted, cooperation among operators, manufacturers, and regulatory authorities is essential.
IV. AI + eSIM: Entering the 2.0 Era, with Completely New Possibilities
With the rise of AI, eSIM has evolved beyond its role as a mere "virtual SIM card." Future AI devices (such as smart glasses and robots) will need their own identity and connectivity capabilities, and eSIM will serve as their digital identity document and information hub. It will enable local processing of sensitive data (e.g., biometric information) to prevent leaks while maintaining connectivity to the cloud. Chip manufacturers also need to upgrade their products to be more reliable, secure (resistant to AI attacks), and energy-efficient (suitable for AI-powered devices). This transformation means that eSIM is moving from a basic communication tool to a core component of the AI ecosystem, opening up vast potential for future developments.
V. The Industry Must Work Together to Succeed
For the eSIM industry to thrive, several challenges must be overcome: standardization of testing procedures for devices and chips (to ensure compatibility across brands), optimization of online and offline account creation and after-sales experiences (to avoid inconvenience for users), and proper management of device certificates (to prevent fraud). Only by addressing these issues can eSIM become widely adopted and realize its full potential in conjunction with AI technologies.
