A free WiFi service on the London Underground will be expanded to new stations.

From the Spring, passengers with O2, EE, Vodafone and Virgin Media contracts will be able to access the system at Leytonstone and Leyton stations.

Currently WiFi is available at 56 stations across the network, but not on trains.   

Customers whose network does not have a deal with Virgin Media can access to Tube WiFi for £2 a day, £5 a week or £15 per month.
