The advantage of eSIM in enabling global IoT connectivity without a physical SIM card presents significant opportunities for enterprises: global IoT connectivity, lower operating costs, and more convenient device management. Especially after the GSMA introduced the Remote SIM Provisioning (RSP) standard SGP.32.
SGP.32 promises to unify and optimize the GSMA's RSP standard and promote the large - scale application of eSIM and iSIM technologies in the Internet of Things field.
Different from the previous SGP.02 and SGP.22 standards, SGP.32 is specifically tailored for IoT (Internet of Things) devices - especially those with minimal user interfaces or limited connectivity. It optimizes the ability to securely manage eSIM profiles on a large scale over - the - air (OTA) in device groups.
When using SGP.32, the trigger point for profile interaction can be either the device side or the cloud/server side. In other words, it supports both push and pull modes, while SGP.02 (push - only) and SGP.22 (pull - only) do not have this two - way flexibility.
The advantages of SGP.32 can be specifically divided into the following four points:
1. Designed for restricted IoT environments: Different from early standards, SGP.32 is optimized for devices with limited memory, unstable connectivity, and no user interface.
2. Modern, modular infrastructure: It introduces two new components: the IPA (IoT Profile Assistant) on the device side and the eIM (eSIM IoT Remote Manager) on the back - end, enabling lightweight and scalable configuration.
3. Based on IP, saying goodbye to SMS operations: SGP.32 replaces the cumbersome SMS - driven method with efficient IP protocols (such as CoAP and DTLS), thereby significantly improving reliability and performance.
4. Global scalability and flexibility: It enables enterprises to deploy and manage IoT devices globally, making connectivity and operator switching easier and smoother.
However, for many enterprises, the reality may be full of challenges. Even with SGP.32, large - scale deployment still poses challenges. The reason behind these challenges is that owning an eSIM is not just about embedding a chip; it also requires investment in infrastructure, systems, and professional capabilities.
In other words, success requires capabilities far beyond chip embedding, including in - depth integration with the device manufacturing process, a secure and stable remote configuration infrastructure, agreements with operators in multiple countries, and continuous device lifecycle management.
Attempting to manage these capabilities independently often requires huge investment and high risks. If an enterprise tries to take on all the complexity of deployment and operation independently, it may fall into a situation of high cost and high risk.
Therefore, forward - looking enterprises usually choose to cooperate with IoT service providers, leaving the complexity to professional teams to ensure that eSIM configuration is feasible and implemented smoothly. By choosing the right IoT service provider, enterprises can convert the potential of SGP.32 into real value.
