The group has released Version 3.4 of its eUICC Profile Package: Interoperable Format Technical Specification (Interoperable Profile Package Specification). The latest version includes major updates to support full alignment with 3GPP Release 18 to enable advanced 5G functionality and secure authentication in 5G network slicing, as well as enabling the remote management of eSIM profiles on low-power and network-constrained devices. Additional updates and clarifications to promote security and interoperability have also been made.

The group has published Version 3.3.1.2 of the eUICC Profile Package: Interoperable Format Test Specification. Version 3.3.1.2 is now a GlobalPlatform-approved test suite, which is part of the GSMA Consumer and IoT eSIM compliance programmes and referenced in GSMA’s eSIM Test Specifications (SGP.23 and SGP.33). Work is now ongoing to develop the test specification for Version 3.4 of the Interoperable Profile Package Technical Specification.

Following the publication of its educational whitepaper, ‘Realising the Benefits of GSMA’s eSIM IoT Specification (SGP.32)’ the group continues to progress work on a new technical paper that will address specific SGP.32 deployment considerations.

Read how the enhancements made to TCA’s Interoperable Profile Package Specification – which is used in every eSIM deployed in the field – stand to further extend the capabilities and benefits of eSIM technology, bringing seamless connectivity and advanced security to new and established use-cases. Learn more.

eSIM shipment volumes collectively reported by TCA members in 2024 surpassed half a billion units, increasing 35% year-on-year to reach 503 million. TCA also estimates that the total available market for eSIM was 514 million units. The growing availability of eSIM-enabled devices was matched by increasing consumer adoption, with consumer eSIM profile downloads* rising by 56%. Learn more.

TCA data shows that despite the residual impact of inflation and the cost-of-living crisis, an improved economic picture in 2024 – which saw demand for smartphones and mobile subscriptions start to recover – positively impacted the eSIM market. Growth was also bolstered by the launch of new eSIM-only devices, eSIM-enabled mid-range models and 5G smartphones. Learn more.
