Munich / Paderborn – COMPRION and Giesecke+Devrient (G+D) have entered into a partnership to provide mutually validated solutions as well as a development and testing environment for SGP.32 based IoT eSIM solutions. Providers and integrators of SGP.32 IoT eSIM solutions can use this offering to verify, even before market launch, that their products are implemented in compliance with SGP.32 and reliably interoperate with G+D eSIMs – including transparent error analysis in the event of interoperability issues.
Security and Clarity for a Complex IoT Ecosystem
With the GSMA’s new SGP.32 IoT specification, the remote management of eSIMs in IoT devices is gaining significant importance. At the same time, the technical complexity of the ecosystem is increasing: with the eSIM IoT Remote Manager (eIM), a key new architectural component is being introduced. “We expect to see a number of eIM implementations from companies that are not yet familiar with the technical environment of eSIM/RSP. Deviations from the specification can lead to issues in the field that are difficult to localize – particularly when interoperability is only tested after deployment,” says Dr. Marcus Dormanns, Director Product Management & Business Development at COMPRION.
Mutually Validated Testing Along the SGP.32 Specification
Against this backdrop, COMPRION – with its longstanding expertise in eSIM test tools – and G+D, the world’s leading full-service provider of eSIMs (eUICCs), eIM, and RSP backend services, are combining their strengths. Both partners have tested their respective components not only individually, but also in joint interoperability tests, thereby establishing the foundation for a practical development and test environment.
At the core of the partnership is a test and development environment based on the COMPRION Test Tools eUICC Profile Manager and COMPRION Network Bridge, together with a G+D Sm@rtSIM Polaris 1.5M SGP.32 eSIM reference test card with integrated IPAe. Interoperability is validated based on a comprehensive test guide jointly defined by both companies. This reference environment enables, for example, the integration and testing of an eIM component.
“Interoperability is the foundation for reliable IoT solutions. With the jointly validated reference environment, we support providers in ensuring this compatibility at an early stage – while adding the high security standards that G+D, as a SecurityTech company, is known for,” explains Andreas Morawietz, Global Head of eSIM & Solutions Portfolio at Giesecke+Devrient.
Benefits for Development, Integration, and Operations
The joint test environment is designed for manufacturers of eUICCs, IoT module and device OEMs, SM-DP+ and eIM providers, mobile network operators (MNOs), as well as integrators and operators of complex IoT use cases, such as those in the automotive sector. Early pre-validation testing helps reduce integration risks, prevent field failures, and sustainably enhance the reliability of IoT solutions.
