The Virgin Media Free WiFi Service on the London Underground was launched before the Olympics, and was a huge benefit to the many thousands of visitors and daily commuters.

It was also recently announced that the service would remain free until the end of 2012 with Pay As You Go options being introduced in 2013.

The service has been continually expanding to add the service to more stations, and today an additional 20 stations have come online and have the Free WiFi service available. This brings the total number of stations with WiFi access to 92, and the service is still on schedule to reach its targeted 120 stations by early 2012.

Jon James, executive director of broadband at Virgin Media said:

WiFi on London Underground has been an incredible success and we’ve rolled out the service to reach even more stations throughout London, from Camden Town to Clapham Common. Our wholesale agreement with EE and Vodafone will keep the majority of Tube users connected for no extra cost and every Londoner and visitor can choose from affordable PAYG options with free, up-to-the-minute travel, news and entertainment for everyone.
