During the 2012 London Olympics a free wifi network was set up by Virgin Media to supply a number of London tube stations with internet access. The network offered visitors and commuters free access to the web whilst on the go in the capital.
Following the Olympics Virgin continued to offer the service for free but eventually began to charge on a daily, weekly or monthly fee. Both EE and Vodaphone signed contracts with Virgin to continue to offer their customers the service for free. O2 however has been left in the cold, still charging their customers to access the underground wifi network. This is however due to change, as from June onwards O2 customers will also be eligible to access Virgins network free of charge.
The network now covers 120 of the 270 London Underground tube stations.
