Virgin Media have now rolled out Wi-Fi to 41 London Underground stations, with 100,000 people getting online down in the tube stations within the first month of the service going live.
One million tweets, Facebook posts, emails and web pages were accessed between June 25 and July 1 alone using the new service.
"Londoners and visitors are loving our new Wi-Fi service and we're on track to connect Tube journeys right across London ahead of the Games," said Kevin Baughan, director of metro wireless at Virgin Media.
"With millions of smartphones, gadgets and devices taken onto the Tube each day, the demand for data continues to grow and we're rolling-out a future-proofed service that makes superfast wireless connections the standard.
"In partnership with TfL, we've achieved a huge amount and have launched a service London can be proud of."
Though Virgin Media plan on having 120 stations online by the end of August, that will also mark the end of the service's run as a free one. After that, you'll have to pay to send your subterranean tweets.
