Transport for London is part way through a roll-out of 4G and 5G connectivity across the tube network and Elizabeth line.
It was supposed to be complete by now, but issues with testing have prolonged the roll-out into 2025. The new tech is a big step-up from the, frankly, temperamental wi-fi signals that only work (sometimes) within tube stations. Indeed, the underground's 5G is often faster and more reliable than that on the surface in central London.
You'll get a phone signal so long as you're on one of the four UK networks: EE, Vodafone, Three and VMO2. Your phone should automatically connect, and there is no extra charge.
We'll chart the progress of the rollout on the simplified map above, which shows only subterranean sections of the network.
Jan 2025: The Bakerloo line is now furnished with 5G between Piccadilly Circus and Embankment. Also, the section of Northern line tunnel between Stockwell and Balham is live, with coverage also possible on the platforms at Oval.
Dec 2024: The entire Elizabeth line now has signal. Most deep-level tubes in the central section are also hooked up.
July 2024: In a major update, all of the Elizabeth line from the western portal beyond Paddington through to Liverpool Street now has coverage. Further progress has also been made on sections of the Northern and Piccadilly lines,
May 2024: Central line now complete from Holland Park to Bank. Signal available in all Elizabeth line stations, if not yet the tunnels. Covent Garden station added.
December 2023: Goodge Street station is added, along with Northern tunnels from Belsize Park to Camden Town, and Central line tunnels between Tottenham Court Road and Holborn. Four Elizabeth line stations have been added: Bond Street, Tottenham Court Road, Farringdon and Liverpool Street.
September 2023: Oxford Circus and Tottenham Court Road are added, along with the Central line track between them. TfL also announces lots of imminent expansions, including the whole of the Elizabeth line, much more of the Northern line and parts of the Piccadilly. Euston's Charing Cross platforms were later added.
June 2023: Mornington Crescent has been added to the network. The tunnels between Camden Town and MC should be kitted out soon.
May 2023: Camden Town has been added to the network. With the eastern stretches of the Jubilee line, and short sections of the Central and Northern lines, approximately 10% of subsurface stations now have access. Mornington Crescent, Oxford Circus and Tottenham Court Road are promised next.
