O2 Phone plans

Big Bundles
These plans give you plenty of minutes, texts and data. Each month you can choose to top up £10, £15, £20 or £30 depending on your usage requirements.

Rolling plans
Get more data for your money when you select this option. Each month your payment will be automatically taken and you will be given an allowance for that billing period. All this goodness comes with no contract.

O2 Data Plans

These are great because it means you can use your iPad or tablet without the need for an open Wi-Fi connection. All you need to do is make sure your tablet has a SIM Card slot.

Every time you top-up you are given an allowance of data which is measured in MB. Once used, you can add more credit for when you need it next. The great thing about these plans is that they are Pay As You Go based so don’t have a contract making them really flexible.
