Emergency Services Network (ESN)
Official supplier

EE is proud to be the official mobile services supplier, and longstanding partner, for the Government’s Emergency Services Network (ESN)
ESN is a critical national communications system that enables fast, safe and secure mission-critical voice, video and data across the 4G network.
It gives first responders immediate access to lifesaving data, images and information in live situations and emergencies on the frontline.
Critical connectivity where it counts
Coverage & resilience: We’re constantly growing our network to give coverage in areas vital for emergency operations. Expanding and hardening the network into remote, rural and hard-to-reach locations, such as road and rail tunnels, and into hundreds of strategic buildings. Airborne operations are benefitting from seamless connectivity up to 10,000ft enabling interoperability with other services. And a fleet of temporary coverage solutions maintain maximum network service availability.
Priority & performance: The network provides always-on priority access, meaning ESN users have mission critical performance, and the ability to pre-empt other users, to receive enhanced quality of service at all times. This means emergency responders can perform their duties effectively and safely.
Privacy & security: Secure communication remains essential to protect sensitive information and ensure the safety of emergency responders. A secure private core network and implementation of a private Public Land Mobile Network (PLMN) code, ensures that sensitive data and communications are securely managed.

Vital for emergency services, great for the public too
ESN is keeping frontline workers safe and ensuring our safety too. As the Emergency Services Network's footprint extends into areas that previously had no coverage, like national parks and remote rural communities, the general public benefits too. It gives the life-saving ability to make 999 emergency calls, no matter what mobile network they’re on. And for EE customers, they benefit from the increased coverage, resilience and performance enhancements made across the wider EE network too.
