Virgin Media is giving millions of broadband subscribers the chance to continue using free Wi-Fi services on the London Underground.
As of today (Tuesday January 29th), the service provider is charging for wireless broadband access on the Tube.
However, the firm's own customers - plus those of four other broadband providers - can continue to use the Wi-Fi service for free.
This is because of a wholesale agreement signed between Virgin Media and Vodafone, EE, T-Mobile and Orange in November 2012.
All UK consumers will continue to have free access to real-time Transport for London travel updates and London entertainment information and news via the network.
But should they wish to take advantage of full Wi-Fi access on the London Underground, they will be required to purchase a Virgin Media Wi-Fi Pass.
A daily pass is priced at £2, a weekly pass costs £5 and a monthly pass is £15.
In a special launch offer, all consumers signing up for the whole of February will receive three months' access for the price of one.
Meanwhile, Virgin Media is continuing to extend its wireless broadband coverage across the Tube network.
Another 11 stations are coming online this week, including Hampstead, Tooting Broadway and Great Portland Street, joining the 92 which already offer Wi-Fi connectivity.
Virgin Media is aiming to equip 120 stations with wireless broadband access by the end of March 2013.
The firm launched its Tube Wi-Fi network ahead of the London 2012 Olympic and Paralympic Games.
Plans to offer wholesale access to the service were announced in June 2012, with EE and Vodafone named as service partners in November last year.
