All about our network expansion

No more worrying about missed calls or buffering podcasts while you travel below the city. O2 customers can get coverage in more than two thirds of tube stations. But it doesn't stop there, because uninterrupted coverage is being rolled out to every station. By the end of 2025, 80% of the London Underground network - including connecting tunnels - will be connected.

In 2023, we jump-started an initiative to improve coverage along key motorway routes, with upgrades already completed on the M5, M11 and M60. More routes will get a boost throughout the coming year, helping to keep you connected on the road.

With tens of millions of passengers travelling through transport hubs each year, railway stations depend on reliable connectivity. Using a dedicated indoor 5G solution, we've enhanced connectivity at key stations like Manchester Piccadilly and London's Fenchurch Street, keeping you in touch while you're on the move.

Our 3G network carries less than 4% of our total mobile data traffic, but uses 11% of our total energy consumption, so we'll begin to switch it off in 2025. It's part of an agreement between the Government and all UK network operators, and we'll be able to reuse the frequencies it frees up to enhance our newer 4G and 5G networks.

In February, we launched the next generation of our 5G network - 5G Standalone. This complete overhaul of our 5G network paves the way for future technological advancements, from remote surgeries to the metaverse and autonomous vehicles. More routes will get a boost throughout the coming year, helping to keep you connected on the road.

To extend our network’s reach, we're using Starlink's technology to connect rural sites, providing coverage in more places than ever before. Using a dedicated indoor 5G solution, we've enhanced connectivity at key stations like Manchester Piccadilly and London's Fenchurch Street, keeping you in touch while you're on the move.
