O2 5G Launch

5G is the connectivity that will completely transform the way we live.
The power of 5G on personal and business devices will give everyone a better and more reliable connection in extra busy places, delay-free downloads and buffer-free streaming. But it’s 5G’s impact on the world around us that’s even more exciting. This new technology has the power to connect buildings, transport and services in ways we’ve never seen, completely revolutionising everything from the way traffic flows on our roads, to the way we receive health care.



Our pick of the best offers and prize draws

Priority is your app for invites to live experiences and perks every day. From ones that get you doing the things you love with the ones you love, to those that bring you the kinds of treats that make you smile.

And they’re all yours just for being on O2. Every year thousands of shows go on sale to O2 customers first. Through Priority Tickets you’ll have a 48-hour window to snap up tickets to your favourite artists before general release kicks in.

And if your show’s at an O2 venue, you’ll get perks around the venue too. Download the app or text Priority to 2020.




The O2 network covers 99% of the outdoor population in the UK, and they’re continuing to roll out 4G in more places all the time. On top of that, they’ve got over 15,000 free O2 Wifi hotspots across the UK. So you can use their data, and save yours.



My O2

My O2 lets you do more from your phone. With the My O2 app (or going to My O2 online) you can see your latest bills, add Bolt Ons if you suddenly need more data on the go and even change your tariff or address. You can even browse some of the latest offers from O2.



Travel in O2’s Europe Zone and you’ll have roaming included – no matter what tariff you’re on. Whether you’re sunning it up in Spain or on the ski slopes in Switzerland, your minutes, texts and data will work just like they do at home.



If you take out a new contract or upgrade with us, you’ll be able to set a Spend Cap on your contract. This will give you a greater control over your monthly spend and help you to avoid bill shock.


You can add, remove, increase and decrease your Spend Cap once a day (with changes taking up to 24 hours to take effect), and you’ll receive a warning whenever the billing limit you set is about to be reached.


**You will be charged for incoming calls if you're using your Equipment abroad outside of our Europe Zone (including the cost of receiving voicemail messages). If you use Services abroad outside of our Europe Zone, it will usually take longer to be billed. It's best to check the cost of using your Equipment abroad outside of our Europe Zone before you travel. Accidental roaming might occur if you are in an area close to national borders because your Equipment picks up a network across the border. If this happens, you may be charged as though you were roaming on an international network. You can prevent this if you are near a national border by setting your Mobile Phone or other Equipment (as applicable) to do a manual network selection and select the 'O2' Network.
