London Underground WiFi and mobile coverage across the tube has been upgraded in a major way! Now, you can enjoy fast and free internet at over 250 different stations (99% of the network), with upgraded 4G/5G mobile coverage in approximately 80-90% of underground areas, including tunnels on key lines, as of September 2025.
EE, O2, Vodafone, and Three are all working closely together with TfL and Boldyn Networks to improve infrastructure across the network. Time to take advantage and save some data!
So, here’s how to connect to the Three, Vodafone, O2, and EE Underground WiFi networks:
Staying connected on the move has never been easier. Simply enable WiFi and wait for your device to automatically connect to the relevant service provided by your chosen operator. For example:
The Big Four are working to improve their Wi-Fi networks across the London Underground and aim to cover all stations and tunnels by 2026, with significant progress in 2025. All of these UK operators are investing in new equipment and technologies to improve the speed and reliability of their services, focusing more on seamless 4G/5G mobile coverage that allows data usage without relying on WiFi.

EE’s London Underground’s WiFi service is powered by Transport For London (TfL) and utilises the same technology as Coverage Boost. It’s a complimentary service for all eligible EE customers, covering ticket halls, walkways, and platforms at over 260 stations – all for free!
EE has taken significant steps to enhance connectivity, launching its network across the London Underground in December 2022, and continuing to upgrade its infrastructure throughout 2025. Very exciting developments are ahead, including better integration with 5G mobile coverage!
Here’s how to connect to the EE Underground WiFi network:
Before you start making your way to the London Underground, make sure you have a compatible EE SIM card first! Please note, this coverage does not yet extend to all tunnels or the stretches between stations, though mobile 4G/5G is expanding to cover these areas.
Now, it’s time to enjoy EE Underground WiFi across 150,000 locations:
Having issues connecting? See the full guide from EE or text “WiFi” to 150 for setup help, or reset network settings if connection fails.
For Pay Monthly Customers: If you are a pay monthly EE subscriber with a compatible device, you are eligible for WiFi access on the London Underground, provided that your account does not have any outstanding arrears or has not been designated as a bad debt.
For Pay-As-You-Go Customers: As an EE pay-as-you-go customer with a suitable device, you can access WiFi on the London Underground by ensuring you’ve topped up your account with a minimum of £5 within the past 30 days.
Please note, it may take up to 48 hours for your account to be updated and for you to gain access to WiFi on the London Underground after topping up.
O2 customers now have the privilege of seamless Wi-Fi connectivity while travelling on the London Underground, thanks to the convenient (and FREE!) service called “Wifi Extra.”
Experience Extra’s benefits in more than 250 Tube stations (99% coverage). O2’s extensive coverage encompasses over 95% of the entire London Underground network, alongside thousands of other hotspots across the country that offer even faster speeds than 4G.
Note: Following the Virgin Media O2 merger, some ex-Virgin users may need to switch plans for full access.
So, here’s how to connect to the O2 Underground WiFi network:
Most smartphones with an active O2 SIM card will automatically establish a connection to Wifi Extra. All you need to do is:
Once these simple requirements are met, you’re all set to enjoy free internet access during your underground journey!
Please note, you must be an O2 mobile customer to access their London Underground WiFi network.
Pay-As-You-Go customers must have topped up at least once within the last 30 days. It can take up to 30 minutes for your top-up to be registered, so don’t leave it to the last minute!
As a Vodafone subscriber, you can freely access their complimentary WiFi network at over 250 London Underground stations. Ensure that WiFi is activated to enjoy uninterrupted service.
Bear in mind that this service is available exclusively within station premises and does not extend to trains or tunnels, providing signal only within the stations themselves (WiFi was reintroduced in 2023 via Boldyn Networks).
Now, here’s how to connect to the Vodafone Underground WiFi network:
The Vodafone Underground WiFi is named “VodafoneWiFi” and should promptly appear in your available WiFi network list when you approach an underground station.
Should you encounter persistent difficulties in connecting to the Vodafone Underground WiFi network, follow these steps:
Stuck? See more instructions from Vodafone. Otherwise, you can read Vodafone’s terms of use for the finer details. If issues persist, toggle auto-connect or reset network settings.
There are no special requirements to use the Vodafone Underground WiFi network. All you need is a compatible mobile device and an active Vodafone plan. Now, go and enjoy your free internet!
Three was the first network to launch free London Underground Wifi for their customers, starting from as far back as 2021. Since then, Three has shown no signs of slowing and continues to upgrade its network infrastructure across London.
So, here’s how to connect to Three Underground WiFi:
Connecting to the Three Underground WiFi is just as easy as the rest on our list. It’s available for all customers and will keep you connected at over 250 stations, all for free. Perfect for your morning commute, or just chatting with friends on your way home.
Once you’re inside any of the 250 active stations, simply:
If password prompts appear (common with eSIM), reset network settings.
Need more info? Read the full guide from Three support.
All customers can access this WiFi network from personal to Three business users, provided your account is still active. Please note, a valid Three SIM must be present in your device in order to connect.
Pay-As-You-Go users must have either sent a text, made a call, or used mobile data within the last 30 days.

Enjoy access to free public TfL WiFi at London Underground and Elizabeth line stations under “The_Cloud”. Additionally, complimentary on-train internet is provided on the above-ground stretches of the Elizabeth line, specifically in the newer Class 710 London Overground trains. For London Overground, it’s now “Sky Cloud” at 81 stations.
Unfortunately, onboard internet is currently unavailable when you travel below ground on the Elizabeth line. However, Transport for London is actively collaborating with Boldyn Networks Ltd to extend this service below ground in the near future. The network is certified “Friendly WiFi” for content filtering and safety.
Transport for London (TfL) spent most of last year rolling out uninterrupted 4G and 5G mobile coverage to all London underground station ticket halls, platforms, and tunnels on the Tube and Elizabeth line networks. This brought internet access to over 220 stations. Most areas will offer complete coverage by the end of 2025, estimated to encompass around 80-90% of stations as of September 2025.
This means that customers will be able to 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. The project also includes the Emergency Services Network (ESN) for first responders.
Since March 2020, commuters on the Jubilee Line have had the convenience of accessing 4G mobile connectivity. This service is operational in eight stations and connecting tunnels spanning from Westminster to Canning Town, with expansions from Swiss Cottage to Westminster ongoing in 2025.

The Northern Line has received a connectivity boost, with 4G and 5G-ready mobile coverage available at Tottenham Court Road Northern Line platforms and Northern Line stations between Archway and Euston, alongside Goodge Street station. Continuous coverage now extends from South Wimbledon to Stockwell, and further to Morden and Kennington as of summer 2025.
Furthermore, this service is also accessible in the tunnels connecting Tottenham Court Road (Charing Cross branch), Chalk Farm and Camden.
Enhanced connectivity is now at the fingertips of Central Line travellers, as they can access both 4G and 5G-ready mobile coverage. This upgrade extends from Oxford Circus to Tottenham Court Road, while also covering the areas of Holland Park, Notting Hill Gate, and Queensway.
Don’t see your stop? Here’s a complete map of mobile coverage across the network.
In the digital age, we need to be connected. That is why having reliable coverage across London is a game-changer.
Not only can you keep up to date on what’s going on in the world above ground, but it can be a lifesaver if you get a little lost or need to send an urgent email. In this day and age, even ten minutes of downtime can spell disaster for a busy businessperson.
Before, customers lost connection and went offline when entering a station, cutting them off whilst on their journey. Now you are able to connect to the WiFi service when in ticket halls, walkways, and on the platform. This is across 250 stations, so you can keep in contact with clients and colleagues when on the move.
TfL will continue to deploy 5G infrastructure on the London Underground network, working with EE, O2, Vodafone, and Three. All providers plan to launch enhanced 5G services across the network in the near future, enabling faster streaming and AR apps underground.
One of TfL’s main goals is to extend Wi-Fi coverage to all areas of the London Underground network, including tunnels and platforms. TfL, alongside the Big Four, are also working to improve the capacity of the network to handle more users.
“There's still work to do before all 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.”
Lastly, 5G remains a key technology that each mobile network operator is currently investing heavily into. This new generation of mobile network technology offers significantly faster speeds and lower latency than previous generations. Who else is excited to see a fully connected London Underground network by the end of 2025?
