SGP.32 Takes the Stage, Links Field Unveils Comprehensive International IoT Solutions at MWC Shanghai 2025

Today, the 2025 Mobile World Congress (MWC Shanghai) came to a close at the Shanghai New International Expo Center. At this grand and highly influential event in the Asian connectivity ecosystem, Links Field made a stunning appearance with its cutting – edge eSIM technology and all – inclusive IoT connectivity solutions, showcasing its exceptional capabilities in the realm of intelligent interconnectivity. As one of the first companies globally to obtain GSMA eSIM SGP.31/32 certification, Links Field not only holds a leading position in eSIM technology but also demonstrates its robust global presence and service capabilities in the IoT connectivity field.
 
SGP.32 Standard Revolutionizes IoT Connectivity
At the exhibition, Links Field fully displayed its eSIM solution based on the latest GSMA SGP.32 standard. Compared to the previous generation of technical standards, the new solution has achieved a qualitative leap in terms of communication stability, compatibility, and global service capabilities. The SGP.32 standard is specifically designed for IoT devices, supporting devices with no UI or limited UI. It simplifies the protocol to enable remote management and introduces the eIM function, which can centrally manage SIM profiles for large – scale IoT devices. This allows for remote triggering of configuration changes without manual intervention. Additionally, SGP.32 reduces direct technical interfaces between operators and devices through eIM as an intermediary, lowering deployment complexity and supporting dynamic policy updates. Operators can remotely adjust device permissions.
Our eSIM technology covers a complete ecosystem from chips to the cloud. Our self – developed eIM intelligent management platform supports the full – life – cycle management of SIM cards. Together with the lightweight IPA intelligent terminal component and the GSMA – certified industrial – grade eUICC chip, it provides a one – stop solution for various IoT application scenarios. Links Field has integrated multiple IoT protocols such as MQTT and LwM2M, perfectly matching a wide range of applications from smart cars to industrial sensors. It is worth highlighting that we also offer a developer kit, significantly reducing the technical entry barrier for customers and enabling them to take the first step in eSIM application at the lowest cost.
 
Scenario – based Implementation, Leading Industry – wide Digital Transformation
Links Field not only continuously innovates in technology but also focuses on the scenario – based implementation and practical application value of its solutions. At this exhibition, we also showcased a variety of solutions, including our self – developed CMP connectivity management platform for enterprise customers, the IoT traffic self – service subscription platform for individual users, international travel plans, and SM – DP + download services. These solutions are widely applied in multiple fields, including smart payment (POS machines), intelligent transportation (drones, connected vehicles), energy management (charging piles, photovoltaic energy storage), smart cities (smart streetlights, IoT metering), security monitoring (4G cameras), smart mobility (eBikes, asset and pet tracking), and smart wearable devices. They serve as a key driving force for digital transformation across various industries.
 
Global Presence, Local Service
Links Field has established a comprehensive global business layout. Currently, we have partnered with over 70 international operators, covering more than 220 countries and regions, providing stable and reliable connectivity services to customers worldwide. Our global presence is not only reflected in network coverage but also in localized service support. Links Field has set up local marketing and service support points in 16 key markets, spanning North America, Latin America, Europe, the Middle East, Africa, and the Asia – Pacific region, ensuring that customers receive prompt responses and professional support locally.
We firmly believe that true technological innovation should serve industrial upgrading and social development. The MWC Shanghai exhibition is not only a showcase of our technological prowess but also a crucial opportunity to deepen exchanges with global partners. eSIM, as the next – generation connectivity technology, has redefined the way global devices connect, allowing smart terminals to truly break geographical boundaries. This is the direction in which Links Field continues to invest – transforming technological innovation into implementable commercial value.
Looking ahead, we will continue to strengthen our collaboration with global partners. While maintaining our technological lead, we will focus more on refining scenario – based solutions. We look forward to joining hands with more innovators to build a borderless, interconnected digital future with smarter connectivity technologies.
