Have noticed Virgin Media wifi being phased out for “VodafoneWiFi” on the tube today, with some stations still having both. The new service appears to connect and function much faster. I’m guessing this is to do with the contract changing for internet on the underground? (I have a Vodafone sim card and my phone automatically connected to Vodafone Wifi, my friends EE sim card kept connecting to the same EE Auto wifi)
