EE runs the UK's biggest and fastest mobile network, offering superfast 4G in more places than any other operator. Ranked UK's best overall network by RootMetrics® - six years in a row.

We’ve built more than 500 new 4G sites in rural areas in the last 12 months, and we’ll build hundreds more in the next 12 months. We’re also improving our indoor 4G coverage with more low frequency mobile spectrum and targeting coverage on roads and railways.

ESN is built on our commercial 4G network, with a dedicated core network providing further resilience and ESN-specific capabilities, including priority access and push-to-talk. We continue to innovate. Solutions include; backhaul for extra resilience, fleet of rapid response vehicles and cells-on-wheels, coverage extensions via vehicles and inbuilding coverage options.
