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 late 2026. 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.
Around 60% of Tube stations that are underground now have coverage. Our updates are archived below.
