All of London’s tube network is set to get high-speed mobile coverage by the end of 2026

TfL’s quest to get high-speed internet coverage on every London tube line and at every station continues. This week the transport operator confirmed that the project has passed another milestone, with more than half of the London Underground’s ‘underground’ stations boasting 4G and 5G.

Now officially 62 of London’s 121 subterranean tube stations have mobile coverage in their ticket halls, corridors and platforms (as well as the entire Elizabeth line, which was fully connected in December 2024). Euston Square, Cannon Street and Battersea Power Station were among the most recent stations to get connected.

4G and 5G has also been turned on for sections of the Circle and District lines for the first time. Two stretches of track on the lines – between Blackfriars and Cannon Street, and Notting Hill Gate and Bayswater – are now live.

Elsewhere, TfL says it expects the ‘vast majority’ of the Northern and Metropolitan lines have internet coverage in tunnels by the end of the summer. The entire project – that is, ensuring 4G and 5G at every ‘underground’ tube, DLR, Lizzy line and Overground station and tunnel – is apparently ‘on track’ to be complete by the end of 2026.

The project to deliver high speed mobile connectivity across the TfL network is being undertaken by Boldyn Networks, with help from Three UK, EE, Vodafone, and Virgin Media O2.

Next up to get internet coverage over the coming months are King’s Cross St Pancras, Gloucester Road, Warwick Avenue and Vauxhall stations. More of the Circle and District lines will be connected, as will parts of the Victoria, Jubilee, Bakerloo, and Piccadilly lines that are closer to the surface.

So, good news if you hate being uncontactable on the tube! But less-good if you actually quite like the blissful quiet of not having internet below-ground. Well, it’s peaceful unless someone’s playing something annoying out loud – read more about TfL’s campaign to crack down on ‘headphone dodgers’ on London transport here.
