Here at The Malt Shovel in Birmingham, we've installed free O2 Wifi, which means we're a 'O2 Wifi hotspot'. Unlike many other kinds of WiFi hotspots, O2 Wifi is free - no hidden charges or nasty surprises, just free, fast and easy internet access. And it's available to everyone, whether or not you're an O2 customer. You can sign up for O2 Wifi at any of its hotspots.
Once registered, your WiFi-enabled devices will be connected automatically every time you visit an O2 Wifi hotspot. You don't need any passwords or usernames to connect, and using the service won't eat into your mobile data allowance.
