UK mobile operator O2 has today become the latest provider to launch free London Underground Wifi connectivity to its subscribers. Like rivals Vodafone and EE, O2's offering Wifi through a partnership with Virgin Media, which has hotspots at more than 120 tube stations across central London.
After registering their devices with O2 Wifi, O2 customers can get started by connecting to a Virgin Media hotspot and selecting O2 from the list of available providers. Then to complete the process, they'll need to enter their phone number in the form that appears.
Unlike some other major cities, London's underground network lacks cellular data reception of any kind, making Wifi a necessity for anyone wanting to get connected while they travel. O2's Wifi partnership with Virgin Media means Three now is the only major provider not yet offering this service, putting the UK's smallest network at a potential disadvantage.
