Mobile phone coverage on the London Underground and the Elizabeth line has expanded again, with more sections going live in recent weeks.

On the Elizabeth line, 4G phone coverage is now live in Paddington, Whitechapel, Canary Wharf, and Woolwich stations, completing the rollout to all the new Elizbaeth line stations. Work to deliver coverage within the tunnelled sections of the Elizabeth line continues, with the first sections between Bond Street and Liverpool Street expected to get coverage within the coming month. The whole line will be completed later this year.

Currently, there is 4G coverage in the stations, with 4G and 5G coverage in the tunnels. The difference is due to some antenna and radio frequency restrictions in the stations that only affect the 5G service. The intention is to add 5G later, but realistically, it’s such a small performance difference that you’d struggle to notice.

On the London Underground, coverage has started to appear on parts of the Victoria and Piccadilly lines, adding to the existing coverage on parts of the Central, Jubilee and Northern lines. The expansion of the coverage means that about a quarter of underground stations now have mobile coverage and increasingly in the tunnels between them as well.

In just the past few days, the tunnels between Euston and Warren Street on the Victoria line, as well as Covent Garden station on the Piccadilly line have also begun receiving mobile coverage. The tunnels between Piccadilly Circus and Hyde Park Corner on the Piccadilly line will also go live in the coming weeks.

Coverage will also begin on the Bakerloo line next month, while the southern end of the Northern line from Stockwell to Morden will soon start to get mobile coverage. 4G and 5G coverage are due to become available at Clapham Common station next week, and further tunnels and stations will go live during the summer.

TfL expects that by the end of this year, a significant proportion of the entire Tube network (around 80% of stations across the network) and the entire Elizabeth line will have mobile coverage. The intention is that, barring a few sub-surface locations, the remainder of the London Underground, along with the DLR, London Overground and the Elizabeth Line, will all have mobile coverage by the end of next year.

The Mayor of London, Sadiq Khan, said: “This is yet another step towards ensuring Londoners and visitors can stay connected on our transport network. I promised that customers would be able to access high-speed mobile coverage at all stations and in tunnels, and I’m pleased to see how quickly the team are moving to enable 4G and 5G connectivity.

“Now, customers can access the latest travel information, keep in touch with colleagues, friends and family, use social media and stream music at every station along the Elizabeth line. This is just one of the many ways we are supporting Londoners as we build a better, fairer and more prosperous London for everyone.”

Boldyn Networks is paying for the mobile coverage rollout at no cost to TfL. Boldyn Networks then leases the capacity they’ve installed to the mobile network operators to cover their costs.

Around 500 people are working overnight across the Tube network to install mobile equipment, and all work needs to be tidied away before the network opens for customers every morning. Once fully delivered, more than 2,000 kilometres of cabling and thousands of radios are expected to be installed within tunnels and stations, all of which will be fitted outside of operational hours.

This website has been running now for over a decade, and while advertising revenue contributes to funding the website, it doesn't cover the costs. That is why I have set up a facility with DonorBox where you can contribute to the costs of the website and time invested in writing and research for the news articles.

It's very similar to the way The Guardian and many smaller websites are now seeking to generate an income in the face of rising costs and declining advertising.

Whether it's a one-off donation or a regular giver, every additional support goes a long way to covering the running costs of this website, and keeping you regularly topped up doses of Londony news and facts.

    Do we know whether the London Overground East London Line (or Windrush as it’s soon to be called) from Surrey Quays to Dalston Junction will also be covered?

    • alistair t says:

      I hear the section from Shoreditch to Dalston is already live….


    • Chris says:

      D’oh! Brain fart moment, was thinking about Dalston being overground (just about) and forgot about the section from Shoreditch northwards!

  2. J says:

    Just from my travels, I’ve noticed Holborn has been live on the Piccadilly for a little while now.

  3. Andrew says:

    Elizabeth line platforms at Whitechapel and Canary Wharf still do NOT have 5G connectivity on EE network.

    My impression of this article is that other networks, except from EE, expanded their area.

    • ianVisits says:

      The article notes that none of the Elizabeth line stations have 5G coverage – that will be added later.

  4. Andrew says:

    Maybe I am misunderstanding the below (from this article):

    On the Elizabeth line, 4G phone coverage is now live in Paddington, Whitechapel, Canary Wharf, and Woolwich stations, completing the rollout to all the new Elizbaeth line stations.

  5. Andrew says:

    Thanks for your reply.

    I have changed my iPhone Mobile Service settings from “5G On” to “5G Auto”, which also includes 4G.

    Reply from TfL complaint:

    Thank you for your email of 20 May about signal on the Elizabeth Line platforms.

    Unfortunately, EE are not currently providing their mobile phone service at these stations. TfL expect EE to resolve their issue soon. We advised you to please contact your service provider.
