Mobile phones and Wi-Fi underground
Mobile coverage
Uninterrupted 4G and 5G mobile coverage is being rolled out to all underground station ticket halls, platforms and tunnels on the Tube, as well as the DLR, Elizabeth line and recently named Windrush line between Highbury & Islington and New Cross Gate.
At stations with coverage, customers can send and receive calls and texts, surf the Web, or scroll through social media feeds without losing the connection when going from above ground to underground.
How to connect
Your phone should automatically search for and connect to the mobile signal as if you were above ground.
There's no need to install any special software or app - just continue to use your mobile phone and, as it's 4G/5G-compatible, it will connect to the station signal automatically.
Current mobile connections
Customers now have 4G and 5G mobile coverage in stations and tunnels on sections of the Jubilee, Central, Piccadilly, Victoria and Northern lines, as well as the whole Elizabeth line.
Elizabeth line
- All stations and tunnels along the line now have mobile coverage
Bakerloo line
- Mobile coverage is available at Piccadilly Circus station
Northern line
- From Highgate station and Hampstead station to Embankment station on the Charing Cross branch. From Clapham Common to Balham on the southern branch
- On the southern section of the line, Oval, Clapham Common and Clapham South stations are live with a mobile signal
Piccadilly line
- Leicester Square, Piccadilly Circus, Covent Garden, Russell Square station and the tunnel section between Hyde Park Corner and Russell Square
Victoria line

If your station does not yet have mobile connection, you can connect to public Wi-Fi.
Charges
There is no charge from TfL - you just use your mobile phone and pay your mobile service operator as normal.
What's next
The first tunnelled sections of the Bakerloo lines will get coverage by the end of 2024.
There's still work to do before all London Underground stations have mobile coverage, including installing the infrastructure, building the connection points and testing systems. All of this will need to be done while continuing to run a busy underground transport system.
We're also working to connect sections of the London Overground (recently named the Windrush line) and DLR that are below ground in the future.
Station Wi-Fi
Wi-Fi is available at:
- All Tube stations
- Most London Overground stations
- All Elizabeth line stations under central London
- Victoria Coach Station
Devices with a sim card will automatically pick up the Wi-Fi signal when you're in a Wi-Fi enabled station. There's no signal in tunnels, but your phone will connect to the signal at the next Wi-Fi enabled platform so you can pick up where you left off.
Using the Wi-Fi service
It's quick and easy to get started - just enable Wi-Fi on your device to connect automatically to the service provided by your mobile network, for example:
- EE WiFi-Auto
- Wifi Extra (for O2)
- Three_WIFI
- VodafoneWiFi
- The Cloud (in London Overground)
Your devices will automatically pick up the Wi-Fi signal when you're in a Wi-Fi enabled station. There's no signal in tunnels, but your phone will connect to the signal at the next Wi-Fi enabled platform so you can pick up where you left off.
Hints and tips
- It typically takes a few seconds to connect to the Wi-Fi service at a Tube station (this delay is due to a security feature). If you're trying to connect at a peak time in a busy station, it may take slightly longer
- If you're not able to connect to the Wi-Fi network before you get on a Tube train, don't try to connect on the train as you travel from station to station. To save battery life, some devices extend the time that they search for Wi-Fi hotspots. It's better to wait and connect when you get off the train
- Contact your mobile network operator with any questions about connecting
