China's Ministry of Industry and Information Technology Explains eSIM Plans, Benefits, and Challenges

Recently, netizens asked the Ministry of Industry and Information Technology (MIIT) about the promotion plans for eSIM cards, prompting the ministry to respond.

MIIT stated that it highly values consumer rights protection and information security, and is actively promoting new technologies. It is currently organizing relevant units to study the application of eSIM technology in tablets, portable computers, and smartphones, with plans to expand its use once conditions are mature.

The article notes that while the U.S. version of the iPhone 14 uses eSIM exclusively, the Chinese version still includes two nano‑SIM slots. Since 2020, MIIT has approved eSIM services for IoT applications, and the three major Chinese carriers already offer eSIM in several cities, though primarily for smartwatches.

eSIM, or Embedded‑SIM, is embedded directly into a device’s chipset, reducing space, improving durability, and allowing remote provisioning. It enables flexible carrier switching without unlocking devices, supporting the growth of IoT and connected vehicles.

However, the ministry highlighted several obstacles to smartphone eSIM adoption: increased information‑security risks, difficulties in managing thousands of device manufacturers, and the need for security assessments before operators can launch eSIM services. Additionally, eSIM could affect carriers’ revenue models and billing processes, potentially shifting settlement to device manufacturers.

Overall, the deployment of eSIM in Chinese smartphones faces regulatory, security, and commercial challenges, suggesting that widespread adoption will require more time.
