I would like to connect to Wifi on London Underground.

i have tried THREE_WIFI but it requires a username and password. 
i do get 4G or 5G signal on certail parts and in stations but I specifically would like to access the Internet for information.

Is it possible and how do I do it?

Hi ​@Scaffoldr ,

You can connect to free Wi-Fi on the London Underground using THREE_WIFI, but it does require a few setup steps:

How to Connect:

-Make sure your device has a valid Three SIM.
-At a participating station, go to Wi-Fi settings and select THREE_WIFI.
-If prompted for a username/password, choose EAP method: SIM (on Android) or ensure your iOS is updated (15.4 or later).
-You may also need to register via your My3 account and wait up to 48 hours for access to activate.

Wi-Fi is available in ticket halls and platforms—not in tunnels. You’ll also get 4G/5G in some stations.

Let us know if it has worked,

Hi this does not work. When I select the three network on London Underground I am asked to enter a login. I am on the latest iOS.

Hi ​@gsweeney76 

 

Thanks for getting in touch. 

Have you previously registered your My3 account?

When signing up to My3, it doesn’t allow me to link my ID #, which based on the above thread, I need to do to get on the WiFi. Any fix?
