Vision and Mission

Supporting standardisation of the SIM telecom ecosystem

Trusted Connectivity Alliance

Enabling a secure, connected future

Why Trusted Connectivity Alliance?

Trusted Connectivity Alliance (formerly SIMalliance) exists to facilitate the growth of connected objects by supporting the standardisation of SIM (Subscriber Identity Module) technology which enables secure mobile connectivity. The end result is protection for service providers assets, device data and end user privacy. 

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 cars, wearables, smart utilities, industry 4.0 and healthcare. They also have a key part to play in delivering security within 5G networks.  

Trusted Connectivity Alliance works with industry partners, including ETSI, Eurosmart, GlobalPlatform, GSMA 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:

  • Development work on a technical specification for GSMA which has been critical in allowing MNOs to load connectivity profiles in an eSIM.  
  • Supporting the maintenance of the hardware SIM in 5G, by educating on the importance of security for networks and users. 
  • Working with GSMA on IoT SAFE, which specifies a common API and define a standardised way for the SIM to securely perform mutual authentication between IoT devices and the cloud.
