Promoting a reliable, scalable and consistent secure connectivity ecosystem


The secure connectivity ecosystem is enabled by an established infrastructure and global specifications, which help to promote confidence, accelerate innovation and reduce costs.

Yet as the pace of innovation accelerates, so too does the risk of market fragmentation and interoperability issues. For example, the increasing deployment of IoT devices with limited bandwidth, power and user interfaces presents new considerations. As does the growing momentum for 5G networks, drive for more sustainable technologies and increasing deployment of integrated solutions.

Overcoming these challenges requires extensive industry engagement and collaboration to promote an interoperable, reliable and scalable connectivity ecosystem.

Key Interoperability Initiatives

  • Stepping Stones for Java Card Applet Developers
    Guidelines to support the development and deployment of SIM-based technologies, addressing emerging interoperability considerations presented by the growing adoption of eSIM technology
  • TCA eSIM Interoperability Service
    Enables operators to proactively test that their eSIM profiles are compatible with a wide range of commercially available devices prior to deployment.
  • Interoperable Profile Package Specification
    Used in every eSIM deployed in the field, the specification standardises the format used for the remote loading of subscriptions onto eSIMs across deployed devices.
  • Remote SIM Provisioning for IoT
    Trusted Connectivity Alliance has been a key contributor shaping the development of GSMA’s eSIM for IoT Specifications.
  • TCALoader Tool
    Enables mobile operators and application developers to download, install and manage applications on the UICC / eUICC to test interoperability across different deployments.
  • Integrated SIM
    Trusted Connectivity Alliance is tracking the evolution of GSMA’s integrated eUICC and educating industry stakeholders on the practical deployment considerations.
