eSIM Interoperability Service

Promoting confidence and trust across the eSIM ecosystem

Trusted Connectivity Alliance has launched an eSIM Interoperability Service to promote increased confidence and trust across the eSIM ecosystem.

Delivered by test solution provider COMPRION, the new service enables mobile and other network operators to test how their eSIM profiles interact with an extensive range of consumer eSIM devices. This will help identify and address individual interoperability and compatibility issues.

About the TCA eSIM Interoperability Service

By curating a test portfolio of eSIM devices currently deployed in the market, including smartphones, wearables, tablets and laptops, the TCA eSIM Interoperability Service – delivered by COMPRION – will help operators proactively test their eSIM profiles are interoperable with a wide range of commercially available devices prior to deployment. This is particularly beneficial for Tier 2 and 3 operators with more limited resource for comprehensive in-house testing.

The service is also anticipated to evolve to support additional testing scenarios that will enable eSIM Subscription Management (SM-DP+) providers and eSIM consumer device manufacturers to improve the interoperability and compatibility of their respective services and products.

Testing can be conducted on a self-serve basis either on-site at COMPRION’s headquarters or remotely. It can also be delivered by COMPRION’s team of experts.

Promoting an Interoperable eSIM Ecosystem

This eSIM Interoperability Service reflects TCA’s proven pedigree over decades promoting interoperability across the SIM ecosystem and its ongoing commitment to supporting the development of eSIM technology

It also complements TCA’s extensive engagement and collaboration with various industry bodies to promote a secure, interoperable and scalable eSIM ecosystem, including GSMA.


“GSMA is very pleased to see the emergence of a service that promotes interoperability between eSIM hardware, operator profiles and servers. With the emergence of eSIM-only smartphones in some markets, this service is essential for consumer confidence.”

Ian Pannell, Chief Engineer, GSMA
