COMPRION and Thales Build SGP.32 eSIM Test Bed to Speed IoT Interoperability
Collaboration between COMPRION and Thales establishes a dedicated, end-to-end SGP.32 validation environment to accelerate interoperability across eIM, IPA, and eUICC implementations
COMPRION has announced a strategic partnership with Thales to strengthen industry readiness for the new GSMA SGP.32 eSIM architecture for IoT devices.
The collaboration aims to provide IoT market participants — including eUICC manufacturers (EUMs), chipset and device makers, mobile network operators, software providers, and cloud providers — with a reliable, standards-based environment to test and validate SGP.32 implementations.
With the introduction of GSMA SGP.32, the eSIM ecosystem expands to include new key components such as the eIM (eUICC IoT Manager) and the IPA (IoT Profile Assistant). While SGP.32 simplifies provisioning and lifecycle management for IoT eSIMs, it also increases the need for precise, seamless interaction across these new roles and interfaces, especially as the specification supports a more open ecosystem model.
Joint End-to-End Test Environment Based on SGP.32
As part of the partnership, COMPRION and Thales are establishing a dedicated test environment for end-to-end validation of solutions based on the GSMA SGP.32 specification.
The environment is built on COMPRION’s testing portfolio — including eUICC Profile Manager and COMPRION Network Bridge — enabling functional and interoperability testing aligned with GSMA SGP.32 requirements. Thales contributes a GSMA-compliant eUICC card with pre-integrated IPAe to equip devices under test.
“With SGP.32, new roles and interfaces are emerging that must be technically aligned with precision. Our joint test environment creates transparency in this early market phase and gives market participants and developers the opportunity to validate their implementations in a structured way,” said Dr. Marcus Dormanns, Director Product Management & Business Development at COMPRION.
Interoperability Tested Across Reference Implementations
As part of the collaboration, COMPRION and Thales have validated interoperability between their respective products, including the Thales MultiSIM IoT eUICC (industrial and automotive grade), Thales SGP.32 IPAe, and COMPRION’s testing infrastructure components eIM, SM-DP+ and IPAd as reference implementations.
This provides ecosystem players with added confidence in standards compliance, including coverage of standardized SGP.32 commands and functionalities within an appropriate validation setup.
Technical Validation Under Realistic Conditions
By combining COMPRION’s test tools with Thales’ GSMA-compliant eUICC implementation, the joint environment supports realistic validation of SGP.32 integrations, helping companies identify risks early and securely embed solutions into complex IoT architectures.
“Having pioneered and supported early eSIM deployments globally, we recognize that robust interoperability is fundamental to ecosystem adoption and critical to long-term operational success. With the introduction of SGP.32, ensuring seamless and reliable interaction between the various market components is more important than ever,” said Guillaume Lafaix, VP Connectivity Solutions at Thales.
Support for Developers and Third Parties
The test environment also enables third-party eIM and IPA developers to analyze, identify, and resolve interoperability issues — with support from COMPRION tools and consulting services — accelerating development and integration cycles.
