Trusted Connectivity Alliance (TCA) has published new guidance to enable Java Card applet developers to maximise interoperability and security across eSIM deployments.
‘Stepping Stones for Java Card Applet Developers’ is the latest release in TCA’s acclaimed ‘Stepping Stones’ series, which provides recommendations and guidelines to support the development and deployment of SIM-based technologies.
TCA’s new guidance addresses emerging interoperability considerations presented by the growing adoption of eSIM technology. It provides an analysis of key recent Java Card technology updates, along with the impact of broader ecosystem developments from 3GPP, ETSI and GSMA. A series of best practices and security recommendations are also detailed to maximise interoperability and ensure applet assets are sufficiently protected. For developers seeking practical guidance, recommendations are collated into a comprehensive ‘interoperability checklist’ to help address common challenges and deliver high-quality applets.
Amedeo Veneroso, Chair of the TCA Interoperability Working Group, comments: “To ensure seamless integration and simplify eSIM deployments across the highly complex mobile ecosystem, it is imperative that applets are compatible and secure. By addressing the unique considerations presented by Java Card technology, TCA’s latest guidance will support developers – particularly those who are new to the eSIM market – in delivering robust and interoperable solutions that enable the delivery of powerful eSIM-based value-added services.”
Bertrand Moussel, Chair of the TCA Board, adds: “TCA’s various Stepping Stones documents have played an important role in guiding industry stakeholders as part of our decades-long commitment to identifying and promoting the need for strong interoperability. This latest guidance from TCA marks another important milestone in our mission to promote trust and simplicity across the secure connectivity ecosystem.”
Other key interoperability initiatives from TCA include the release of the new, free-to-use TCALoader tool, which enables mobile operators and application developers to download, install and manage applications on the UICC / eUICC to test interoperability across different deployments.
TCA has also reported growing industry momentum for its eSIM Interoperability Testing Service – delivered by COMPRION. The service enables mobile operators, mobile virtual network operators (MVNOs), IoT connectivity providers and eSIM profile developers to test how eSIM profiles interact with an extensive range of consumer eSIM devices such as smartphones, wearables, tablets and laptops. This helps to proactively identify and address individual interoperability issues prior to deployment.
‘Stepping Stones for Java Card Applet Developers’ is available to download here. For further information on the eSIM Interoperability Service and TCALoader, contact info@trustedconnectivityalliance.org and visit the TCA and COMPRION websites.

Version 1.0 April 2024
DownloadWe are entering a new age of global connectivity, fuelled by a continually expanding IoT ecosystem transforming the way we live and work. Yet at the same time, threat levels are increasing, with Accenture reporting a 125% increase in cyberattacks in 2021. This means that the need for truly trusted mobile connectivity has never been higher.
This is where TCA enters, with its focus on a number of key initiatives that enable stakeholders across the connected industries to unlock the benefits of Tamper Resistant Elements (TREs), including SIM, eSIM and integrated SIM.
Key priorities include:
- Driving eSIM interoperability and expanding eSIM benefits to emerging IoT market segments.
- Enabling IoT device security by leveraging the benefits of TREs.
- Educating the industry with the practical deployment considerations for integrated SIM technologies.
- Optimising 5G SIM technology for private networks, 5G network slicing use cases, and 5G device security.
Driving these initiatives are TCA’s dedicated Working Groups, which are responsible for anticipating market needs and developing associated, enabling specifications that leverage our members’ unparalleled technical and industry expertise. Our working groups also engage and collaborate extensively with other associations and stakeholders to support new business models.
This technical update marks the first of our quarterly reports providing insight into the activities of each working group and demonstrating how they are shaping the future of trusted connectivity.
