Other Key Points Discussed at the eSIM Seminar 2025
- China Unicom has launched a new “iPhone eSIM” portal where an independent eSIM number can be activated for iPhones, but the service is not yet operational.
- Apple stated that eSIM is better for the environment as it eliminates the need for physical SIM cards.
- OPPO’s representative emphasized the importance of machine-card binding and standardized R&D.
- NXP reiterated its commitment to data privacy and localization.
- Jide said it is necessary to align China’s eSIM standards with international guidelines so that all companies can move forward together.
To put it simply, suppose you have a Xiaomi smartwatch that supports eSIM. Earlier, you had to insert a physical SIM card for mobile network access, but now with eSIM technology, you can simply scan a QR code to connect your watch to a mobile network. This not only saves space but also allows for a more compact device design.

The Future of eSIM Technology: Why Is It Important?
eSIM technology is going to lay the foundation for future connectivity as it offers a digital solution to the traditional physical SIM card. It allows for more compact and waterproof device designs, which is especially beneficial for smartwatches, fitness bands, and other small gadgets. Moreover, eSIM enables users to add multiple profiles on a single device, making it easy to switch networks while traveling internationally or changing service providers without swapping SIM cards. In terms of security, it is superior as it can be remotely activated or deactivated. Also, by eliminating the need for plastic SIM cards, it contributes to environmental conservation. Hence, eSIM is not just technological advancement, but a significant step towards a convenient, secure, and sustainable digital future.
Additional Information on eSIM Technology:
The seminar also highlighted that in the future, eSIM technology will extend beyond smartphones to play a major role in IoT devices, smartwatches, and AI-PCs (AIPC). Lenovo called eSIM connectivity in AIPC devices a gamechanger. There was a detailed discussion on the testing standards for the three GSMA eSIM types – M2M, Consumer, and IoT. OPPO advised focusing on new technological aspects like machine-card binding. NXP highlighted the importance of local standards and data privacy. Apple emphasized the environmental and security benefits of eSIM. Xiaomi explained the hardware architecture of eSIM in smartphones and wearables.
