The development of GSMA’s eSIM IoT Technical Specification (SGP.32) is a transformative development in global connectivity. By introducing a dedicated Remote SIM Provisioning (RSP) model tailored for IoT devices, SGP.32 promises to further accelerate the adoption of eSIM technology across established and emerging IoT verticals.
The industry is now working to turn this promise into reality. The latest Trusted Connectivity Alliance (TCA) market data shows that the market is embracing SGP.32 to simplify the remote provisioning and management of IoT devices, with a strong increase in the number of eSIM Subscription Manager (SM-DP+) platforms that support profile downloads in accordance with the specification.
But as marketplace adoption of SGP.32 starts to build, promoting and maintaining security and interoperability must be a priority. There are a vast number of potential IoT use-cases and, to reflect this diversity, SGP.32 is intentionally flexible to allow for multiple implementation options and various deployment scenarios. However, there needs to be a consistent baseline across all deployments to ensure the benefits are fully realised.
To support this need for interoperability, there is also demand across the industry for more technical guidance. As with any new major technology initiative in the early stages of adoption, ecosystem stakeholders are still working to understand how to best optimise deployments to meet their specific requirements.
In response to this collective need, TCA has published a new paper – IoT eSIM (SGP.32): A Technical Guide. Developed by TCA’s IoT RSP Working Group, which comprises leading industry experts directly involved in the development of the SGP.32 specification within GSMA, the paper provides industry participants with:
- An overview of the SGP.32 ecosystem, outlining the considerations posed by architectural changes, the introduction of new entities, new and inherited concepts and key data exchanges.
- Technical guidance to address key operations and deployment scenarios.
- Insights explaining the role of the supporting testing and compliance programme, and the potential for future enhancements to the SGP.32 testing infrastructure.
