Get online on the Underground with Wifi Extra

O2 customers can enjoy access to WiFi on the Underground with Wifi Extra. Available in ticket halls, walkways, on escalators and platforms at over 250 Tube stations – that’s over 99% of the London Underground network.


Most current phones with an O2 sim will connect automatically. You just need to make sure that your software is up to date, your WiFi is switched on and you’ve topped up in the last 30 days if you’re on Pay As You Go. Then you’re good to go.
