Transport for London (TfL) has announced that increased high-speed 4G and 5G coverage will be available on new sections of the Tube network.
TfL and Boldyn Networks completed further installation works to expand mobile coverage on the network along the Northern line.
This included the tunnelled section between Balham and South Wimbledon recently getting mobile coverage, as well as Kennington, Oval, Tooting Broadway and South Wimbledon stations.
On the Victoria line, coverage is now being rolled out between Vauxhall and Pimlico which followed coverage on the Piccadilly line and Victoria line being extended up to King’s Cross St Pancras earlier this year.
The Elizabeth line achieving full 4G mobile coverage last year, enabling hundreds of thousands of customers to browse the internet and make calls while travelling along London’s newest rail line.

TfL announced that these upgrades mean that customers in South London travelling along the Northern line from South Wimbledon to Stockwell now have continuous coverage.
All four mobile network operators (Three UK, EE, Vodafone, and Virgin Media O2) are taking part in the rollout, with TfL and Boldyn working to introduce high-speed mobile coverage across the whole rail transport network.
This includes the Tube, Docklands Light Railway and Elizabeth line network, including on the Windrush line between Highbury & Islington and New Cross.
The UK deputy mayor for transport, Seb Dance, said: “The introduction of 4G and 5G along further stretches of the Northern, Piccadilly and Victoria line means even more Londoners will now be able to stay connected on the Underground, reading, streaming or catching up with loved ones.
“This is yet another step towards delivering the mayor’s commitment to rolling out 4G and 5G across the whole Tube network, building a better London for everyone.”
Achievements and innovations in connectivity will be recognised and celebrated at the fourth annual CiTTi Awards on 25 November 2025 at De Vere Grand Connaught Rooms in London. Visit www.cittiawards.co.uk to learn more about this unmissable event for the UK’s transportation sector!
