For the verification of the USIM/USAT function of mobile devices with an eSIM, COMPRION unveils the new nrUICC (non-removable UICC) USIM/USAT tests for 5G mobile device testing. “Due to the permanently installed eSIM in mobile devices, chipset and mobile device manufacturers no longer have a physical interface for testing the device according to 5G relevant USIM/USAT requirements”, explains Andreas Bertling, Director Technology & Business Development at COMPRION. Therefore, COMPRION is working closely with the leading manufacturers to solve this problem and is actively involved in the creation of new test specifications for the USIM/USAT nrUICC tests (3GPP TS 31.127, TS 31.117). Already now, COMPRION offers a test solution based on the current state of knowledge.

Another focus is on the further developed eUICC Profile Creator, a software tool for the development of TCA (Trusted Connectivity Alliance) compliant eSIM profiles. “An eSIM profile affects essential properties of the communication services of an M(V)NO, for example, security, privacy, and roaming. With eSIM technology and COMPRION’s eUICC Profile Creator, M(V)NOs are now also able to create, adapt and validate their own profiles easily and quickly. Compared to the previous SIM technology, M(V)Nos can now manage their communication products directly and more self-sufficiently,” explains Marcus Dormanns, Lead Innovation Manager at COMPRION.

Thus, the COMPRION solution portfolio supports the entire eSIM value chain – from the development of chips and devices to the creation and validation of profiles, to the testing of remote SIM provisioning back-end services.
