en.Wedoany.com Reported - From June 24 to 26, Unisoc showcased its full range of eSIM product matrix at the eSIM zone in Hall N4 of MWC Shanghai, held at the Shanghai New International Expo Centre, and jointly released an innovative eSIM terminal intelligent acceptance solution with China Unicom. As a pioneer in the domestic eSIM field, Unisoc aims to demonstrate its industrial construction capabilities spanning from product technology to scenario applications, and from global commercial deployment to localized convenient services.
Currently, eSIM applications are expanding from consumer electronics to diverse scenarios such as the Internet of Vehicles and the Internet of Things, becoming a key foundation for ubiquitous connectivity. Leveraging over two decades of experience, Unisoc has transformed innovative eSIM technologies into practical products: its products have passed real-network tests by global operators, achieved mass production in multiple overseas countries and regions, and have been implemented in several mainstream eSIM smartphone models carrying operator certificates in China, with cumulative shipments reaching tens of millions. These products are widely used in consumer scenarios such as smartphones, wearables, tablets, and smart POS terminals, and have achieved a breakthrough in mass production in the Chinese automotive chip sector.
To address issues such as cumbersome processes, low efficiency, and risks of information leakage commonly associated with QR code and barcode technologies used in eSIM smartphone services at domestic offline business halls, Unisoc, in collaboration with China Unicom, has developed the industry's first innovative eSIM terminal intelligent acceptance solution based on the jointly established China Unicom 5G eSIM Joint Innovation Laboratory. This solution deeply integrates the capabilities of underlying hardware security chips with the operator's business acceptance system, aiming to fill the security gaps of the traditional QR code activation model and bridge the last mile of implementing security technology capabilities in civilian communication services.
The solution builds three core security capabilities: First, it establishes an independent encrypted direct connection channel between the user terminal and the operator's business backend, eliminating the need for manual QR code scanning. The system automatically and in real-time obtains core terminal activation data, reducing service processing time. Second, it adopts a standardized key exchange strategy to complete bidirectional data encryption and identity authentication between the operator's business system and the user's smartphone terminal, intercepting malicious attacks and data tampering risks at the transmission link source. Third, it leverages a multi-CI certificate system to verify the legitimacy of the terminal's eUICC chip, ensuring that the identity of each terminal handling services is authentic and traceable, preventing illegal terminal network access at the hardware level. This solution integrates the entire process of device verification, service activation, and profile download, simplifying multiple manual operations into a seamless "one-touch connection" service. Compared to full-process QR code and barcode scanning operations, it significantly reduces service processing time while constructing an end-to-end complete security defense line from the security chip and smartphone terminal to the operator's backend, completely avoiding the data security risks posed by traditional scanning modes.
Currently, this innovative solution has successfully completed the first phase of industry chain adaptation and deployment testing. All eSIM smartphone models currently on the market support this acceptance mode, and its mature deployment capability has been fully verified across the industry chain.
