O2 mobile broadband customers will be able to take advantage of free Wi-Fi services on the London Underground from July 22nd.
The service provider has announced the launch date for its Tube Wi-Fi service, which will use the network constructed by Virgin Media originally for the London 2012 Olympic Games.
Virgin Media has signed wholesale agreements with a number of rival broadband providers - including EE and Vodafone - allowing them to offer Wi-Fi services to subscribers at 120 stations on the London Underground.
Other consumers have the option of paying for daily, weekly or monthly passes in order to access the subterranean Wi-Fi service.
Speaking to V3.co.uk, a spokesperson for O2 said the firm was currently testing underground Wi-Fi in order to ensure "fully operational service upon launch".
"The service will be officially switched on July 22nd and available, for free, to all O2 Wi-Fi registered users," the representative stated.
