Vision and Mission

Supporting standardisation of the SIM telecom ecosystem

Trusted Connectivity Alliance

Enabling trust in a connected future

Why Trusted Connectivity Alliance?

Trusted Connectivity Alliance (TCA) exists to drive the sustained growth of a connected society by supporting the standardisation of SIM (Subscriber Identity Module) technology which enables secure mobile connectivity. The end result is protection for assets, end user privacy and networks. 

The organisation enables collaboration among all those who engage within the global SIM ecosystem. While this ecosystem was previously the domain of SIM vendors and mobile network operators (MNOs), the growth of the internet of things (IoT) in recent years has created new use cases for SIM technology beyond authenticated access to mobile networks. SIM solutions are now being considered and deployed in many connected industries where security is paramount, such as connected carswearablessmart utilities, industry 4.0 and healthcare. They also have a key part to play in delivering security within 5G networks.  

Collectively, Trusted Connectivity Alliance members work to define requirements and provide deliverables of a strategic, technical and marketing nature that enable stakeholders across connected industries to benefit from the most stringent end-to-end secure connectivity solutions.

Trusted Connectivity Alliance also works with industry partners, including ETSIEurosmartGlobalPlatformGSMA and MIPI Alliance, to support the continued standardisation of the SIM ecosystem alongside other technical industry associations and standards bodies. 


Key Achievements

By enabling trusted mobile connectivity, Trusted Connectivity Alliance provides the foundation for the continued growth of connected objects globally. The organisation will further its achievements (delivered by SIMalliance) in recent years, which include:

  • Ensuring eSIM interoperability and expanding benefits to more IoT use-cases.
  • Leveraging SIM technology for IoT security, including continued collaboration with GSMA on IoT SAFE.
  • Evolving and optimising 5G SIM technology to enhance 5G network services.
  • Highlighting the importance of subscriber privacy in 5G.
  • Promoting consistency across integrated SIM technologies.
  • Enhancing the market monitoring process to deliver industry-leading insight.
TCA has published its annual market monitoring data showing significant global eSIM growth in 2020, with eSIM shipments collectively reported by TCA members increasing 83% year-on-year to reach 309 million units. Learn more here.
