Oxford Circus, King's Cross, Liverpool Street and Leicester Square are among the first London Underground stations to offer Wi-Fi as Virgin Media revealed the 80 stations that will get the service by the end of July.
Virgin Media won the contract earlier this year to provide the service. It will be free until the end of the Paralympic Games in September and then offered on a pay-as-you-go basis and to Virgin Media subscribers.
London Underground director of strategy and service development Gareth Powell said: 'Our customers will soon be able to connect to the internet for live travel information while they are on the move through stations.
'Bringing a next generation W-iFi service to one of the world’s oldest underground transport networks is progressing as planned and the forthcoming service is testing well.
'The first stations include some of our busiest and most well-known destinations and we’re on-track for a successful launch this summer – all delivered at no additional cost to fare payers or taxpayers.'
Virgin Media executive director of broadband Jon James said: 'In partnership with TfL, we’ve been working around-the-clock to install and test Wi-Fi on London Underground and are about to connect some iconic and world famous Tube stations with a Wi-Fi service London will be proud of.'
