O2 customers can finally access Virgin Media's London Underground WiFi network for free.
O2 announced its intention to offer free access earlier this year, but the service has now finally gone live, after earlier promises it would be available last month.
Virgin built most of the network in time for the London Olympics last year, and has since offered access to it to mobile operators on a wholesale charging basis, allowing them to offer free access to their customers.
Virgin Mobile customers were the first to gain free access to the network, followed by EE customers across the Orange and T-Mobile brands. Vodafone followed and has now been joined by O2 - leaving just Three customers frozen out from free access.
Over 120 London Underground stations are so far covered by the WiFi network, which allows access in booking halls, platforms and while trains are at those stations - there is no access in the tunnels.
O2 customers already signed up to O2 WiFi (via a hotspot or the O2 WiFi app) will be automatically registered to the London Underground WiFi. Once they have signed in for the first time via the online portal, their devices will automatically connect each time they enter a WiFi-enabled station.
Gary Booker, marketing and consumer director at O2, said: “Our customers want to stay connected wherever they are and now they are able to check their email, update their Facebook status, shop online, and stay connected to their friends and family right across Tube stations in Central London."
