eSIM evolution in the UK: policy implications of a digital shift

This webinar will explore the transition to eSIM technology in the UK and related markets, examining its implications for consumers, telecom providers, and national cyber security. With the UK government currently consulting on updates to the Telecommunications Security Code of Practice, this is a timely opportunity to assess how policy, market dynamics, and technology intersect. 

An eSIM (embedded SIM) is a digital alternative to the traditional physical SIM card. Built directly into devices, eSIMs allow users to activate and switch mobile plans remotely, without needing to insert or replace a physical card. This innovation is reshaping the mobile connectivity landscape by offering greater flexibility, reducing environmental waste, and enabling new models for international roaming and customer mobility. 

The benefits of eSIM technology extend well beyond end users, offering significant advantages across sectors such as retail, logistics, and manufacturing. By enabling and simplifying the management of millions of connected devices, eSIMs play a crucial role in supporting IoT applications. They also provide secure, flexible connectivity for enterprises deploying private 5G networks, and facilitate seamless cross-border cellular access across multiple providers with minimal complexity. When combined with AI and cloud infrastructure, eSIMs have the potential to evolve even further, unlocking new possibilities for innovation and efficiency. 

The importance of eSIMs lies in their potential to empower consumers, streamline mobile operations, and enhance device security. However, they also introduce new challenges, particularly around remote provisioning, fraud prevention, and regulatory oversight. As eSIM adoption accelerates globally and in the UK, traditional market structures are being disrupted, with device manufacturers, MVNOs, and digital-first operators gaining influence, while legacy providers face pressure to adapt. 

This webinar will bring together experts from across the telecoms, cybersecurity, and policy sectors to explore how the UK can navigate this transition — ensuring innovation is matched by robust consumer protections and regulatory clarity.
