Today, China Mobile Wuxi officially launched the Smart Mobile China Mobile Inside program, and at the same time released the first domestic chip that provides "eSIM+ connection service".

China Mobile Inside plans to launch the first C417M series chip, which is China Mobile's own brand and cooperates with Ziguang Zunru to develop R&D. Its main feature is to integrate China Mobile's eSIM function, support aircard writing, and minimize the terminal size while avoiding it. The environment of the deployment scenario is terrible or the vibration may cause the SIM card to be in poor contact and unable to communicate, further enhancing the stability of the chip.

In simple terms, the eSIM and the current mobile SIM card functions are the same. The difference is that the mobile SIM card is a physical card that is inserted into the card slot of the terminal when in use; and the eSIM is an electronic SIM card. , download and install to the terminal through the network.

Any terminal device that needs to access the mobile communication network can use eSIM. eSIM also has applications on mobile phones. The international roaming function implemented on many mobile phones can also be used on various Internet of Things terminals in future eSIM, such as smart meters, smart homes, industrial equipment, agricultural equipment, drones, etc. .

The "eSIM+ connection service" release of the chip also means that mobile phone users will gradually leave the physical SIM card.

It is understood that this series of chips integrates the China Mobile SDK and can seamlessly access OneNET, the China Mobile Internet of Things open platform, to help enterprises achieve rapid and low-cost R&D of upper-layer applications. In addition, the on-chip FOTA functionality enables the product to continue to enhance functionality and fix problems after it is released.

The chips released this time include C417M-S and C417M-D. Both support the mainstream LTE bands of China Mobile and global carriers, and support Bluetooth, Wi-Fi, FM and GNSS multi-mode satellite positioning to meet Bluetooth calls, Many practical scenarios such as music playback and positioning navigation are required.

For terminal manufacturers, eSIM packages from the chip level have higher reliability and tolerance to harsh environments. The eSIM function is directly embedded in the communication chips purchased by terminal manufacturers, simplifying the production process. At the same time, the terminal manufacturers do not need to interconnect the chip manufacturers and operators, effectively reduce the communication costs, and can more effectively protect the security of communication information, and will play an important role in the areas of vehicle networking, smart wear, and industrial equipment monitoring.

In order to accelerate the development of the industry, China Mobile has also launched a number of supporting policies. In terms of content and channel operations, China Mobile and Guangzhou Mobile will vigorously promote industrial cooperation based on the China Mobile Inside program, and provide more value-added services for industry chain partners and end customers, including online real-name authentication capabilities, and major number payment. Capabilities, terminal management capabilities, local information value-added services (insurance, transportation, education, etc.). Combine local mobile user resources, develop channel capabilities, and further promote industrial cooperation and in-depth operations.

For the individual user market, Guangzhou Mobile has launched the “1+N&rdquo” IoT marketing model to promote the in-depth operation of “individual user + Internet of Things cards”. Integrate China Mobile Inside custom chips to explore the business model of "business + terminal". Through the "1+N" marketing model, it provides individual customers with end-to-end services such as number-based payment, online processing, online real name, online payment, and online delivery. Reduce customer transaction costs.

At the same time, it will also provide special subsidies for terminals participating in the China Mobile Inside program. In the first phase, the owners of private car owners will enjoy the package and the smart wearable package for parents. The owner of the package enjoys only one yuan per day, and enjoys intelligent services such as dynamic navigation, voice interaction, audiovisual entertainment, and rescue. Parents and children enjoying package users only need to pay 1 yuan per day to enjoy intelligent services such as voice calls, precise positioning, weather forecasting, and sports step counting.
