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.
