Wifi on the Underground
Before you can use wifi on the London Underground, you'll need to register for O2 Wifi. You can download the O2 Wifi app for iOS and Android, or register in any one of our 1000s of O2 Wifi hotspots.
Look out for stations with wifi on the Underground sign. You can find a map of these hotspots here.
If you can't use wifi on the Underground
While anyone can use O2 Wifi, you must be on O2 to use wifi on the Underground. So, if you registered for O2 Wifi using a number from another network, then you won't be able to use it.
You'll need to ensure that your bills are up to date. If you're on Pay As You Go, you'll need to have topped up at least once in the last 90 days. Once you top up, you'll be able to use the service again - it’s worth noting that it can take up to 30 minutes to register your top up.
If you want to change the number from the one you used to register for the service, then you'll need to delete your account and register with your new number. This can be done via the O2 Wifi app, or by logging in to My O2.
