Everything you need to know about the O2 Sim Only Deals

O2 Coverage

O2 Coverage

O2 SIMS are served by reliable and widespread O2 network coverage, which now reaches 98% of the UK population. And when you're not using your data, you can still surf, stream, and download, at one of 15,000 free O2 Wi-Fi hotspots nationwide.

Adventuring further afield? Call, chat and surf across the continent as if you were at home, with EuropeZone roaming at no extra cost. Take your monthly data allowances with you as you travel through Europe, with no added charges.

O2 Priority

O2 Priority

With an O2 SIM only deal, you’ll be all set to enjoy O2’s fantastic rewards app – O2 Priority. Make the most of weekly freebies and discounts on the high street, as well as regular competitions and other in-app rewards.

When you download the O2 Priority app as an O2 customer, you’ll also have pre-sale access to hundreds of gigs and other live events across the UK. Enjoy live entertainment courtesy of O2, with pre-sale access up to 48 hours before general sale.

My O2 App

My O2 App

Stay up to date every month with the handy ‘My O2’ app. Available on both Apple and Android, you can stay on top of your billing, data usage, and any out-of-bundle costs you may have occurred, all collected together in one easy-to-use location.

To make things even easier, My O2 can synch up with your mobile contacts, so you can easily see who you’ve called and texted when viewing your bill. The app is fully safe and secure, and you can employ your phone’s biometric sign in for extra protection.

O2 SIM Sizes

O2 SIM Sizes

There's no need to worry about what size you need when ordering, as all our O2 SIM only deals are dispatched as a 'combination SIM' which can be resized to fit any SIM tray. We have a huge range of SIMs to suit every need, from all the major networks. Find the perfect SIM only deal for you today.

If you're someone who likes to keep their options open, why not go for a rolling 30 day plan? These come with all the perks of a standard SIM only contract, but don't tie you down as you can cancel your connection whenever you like.
