Fon is the world’s first global wi-fi network and aims to give all its members access to wireless broadband wherever they are in the world. Since March 2009, all new BT Broadband customers are automatically members of the Fon community and agree to securely share a portion of their wi-fi bandwidth through a separate channel on their hub.
Sharing your wi-fi with Fon is safe and secure, and you won't even notice when others are connected because Fon only uses a tiny portion of your bandwidth.
In return, you can use the world's largest wi-fi network for free. That's over 20 million wi-fi hotspots around the world.
Participating BT Hubs are known as BTWifi-with-Fon hotspots.
