No passwords or usernames to connect. And it won’t eat into your mobile data allowance. Just quick WiFi, whenever you’re near one of our O2 WiFi hotspots.

O2 WiFi’s wireless network is one of the most secure public access networks.
We have implemented a number of technologies to ensure your device and connection is as safe as possible whilst connected to one of our hotspots. We’ve created a personalised welcome page with your name displayed, so when you enter an O2 WiFi hotspot you know it’s genuine.
