Virgin Media has signed a deal with EE and Vodafone to allow their customers to use its Wi-Fi network on the London Underground.
Virgin Media offered free Wi-Fi on the London Underground in summer 2012 for anyone travelling through the 72 Wi-Fi enabled stations.
However,in October Virgin Media confirmed its Wi-Fi access on the Tube would only remain free until 2013.
Originally,only Virgin customers be able to access Wi-Fi on the Tube at no extra cost.But the wholesale deal means that,after 2012,EE and Vodafone customers will be able to access the service.
"Wi-Fi on London Underground has been an incredible success,with over 700,000 people already online and a remarkable million sessions every day,"said Jon James,executive director of broadband at Virgin Media.
"We're rolling out the service to reach even more stations throughout London,from Camden Town to Clapham Common and,thanks to our partnership with EE and Vodafone,the majority of Tube users can stay connected for no extra cost."
