Virgin Media has announced plans to launch Wi-Fi services at another seven London Underground stations.
Wireless broadband will go live at Shepherds Bush, Edgware Road (Bakerloo line), Hammersmith (Hammersmith & City line), West Brompton, Harrow on the Hill, Bow Road and Ealing Broadway this week.
This will take the total number of stations with access to Virgin Media Wi-Fi to 144.
The network operator originally launched its Tube Wi-Fi network for the London 2012 Olympic Games, and has continued to upgrade it over the last two years.
Virgin Media, EE, O2 and Vodafone customers have been able to access the service free of charge since it launched, thanks to a wholesale agreement.
For the first time since charges were introduced in early 2013, Three subscribers will also gain access to free Wi-Fi this month.
A new deal struck between Virgin Media and Three means every UK mobile operator is now a wholesale partner for the London Underground Wi-Fi service.
This means the vast majority of Tube passengers can get online throughout ticket halls, on the escalators and on platforms in connected stations.
Joe Lathan, Director of Broadband at Virgin Media, said: “With every network operator now on board with Virgin Media Wi-Fi on London Underground, it is great to know we are keeping people on the Tube connected at no extra cost.
"Our unique fibre-optic network has enabled us to bring connectivity to even the deepest Tube stations and we’re looking forward to getting even more parts of the capital online."
Gareth Powell, London Underground’s Director of Strategy and Service Development, said the Wi-Fi service has "moved from strength to strength" since it launched in time for the London 2012 Olympic Games.
"We’re delighted that another mobile operator is on board because it means more of our customers benefit from live travel information, news and social media throughout the majority of our stations," he stated.
