O2 Wifi

O2 Wifi

Unlike other wifi hotspots, O2 Wifi is free to use and available to users on all networks. You do, however, have to be over 18 to register and accept our terms and conditions.
You can use O2 Wifi to browse the web, make phone and video calls over the internet and watch online videos. All of these services work better over wifi than a standard 3G or 4G network or web dongle.
