Wi-Fi is now available at 92 London tube stations.
Another 20 stations have come online as Virgin Media continues to roll out its Wi-Fi service on London Underground.
The roll out includes stations such as Camden town, Clapham Common, Finsbury Park and Swiss Cottage.
Virgin media claims that 800,000 people have registered with its Wi-Fi service so far.
The company plans to bring the service to another 28 stations by early 2013.
"Thousands of our customers are already using Wi-Fi at Tube stations to keep up-to-date with live travel information, news and entertainment," said Gareth Powell, director of strategy and service development for London underground. "The arrival of Wi-Fi at these extra 20 stations will allow even more of our passengers to connect to the net while they are on the move across London."
Virgin Media also plans to launch a Pay As You Go (PAYG) option offering daily, weekly and month passes.
Tube passengers can purchase a daily Wi-Fi pass for £2, a weekly one for £5 and a monthly one for £15.
Virgin media recently announced taking on EE and Vodafone as wholesale partners for its Wi-Fi underground service.
The partnership means that besides virgin media customers, EE, Vodafone, Orange and T-Mobile customers will also be able to access Wi-Fi at no additional cost.
"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," said Jon James, executive director of broadband at Virgin Media.
"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."
