From 1 July 2013, as an O2 customer you'll need to use O2 Wifi hotspots to get online instead of hooking up to one of over 4,000 BT Openzone hotspot locations you may have used.  Don’t worry though, we have over 8,000 free O2 Wifi hotspots to choose from. With more popping up all the time.  Take a look at our O2 Wifi hotspot directory to find out where they are.
