If you don't use your phone very often and don't want to be tied to a contract, O2 offers Pay As You Go bundles. These plans will provide you with all the essentials you need, and any extras you want, without the need for a contract or credit check. All Pay As You Go plans include unlimited calls and texts, free roaming and the ability to roll over unused data each month.
You will also receive daily offers with O2 Priority, which mean you could get your hands on free tickets, deals and experiences, while there may be promotions which will allow you to keep your credit and use it when you want. What's more, if you sign up to TopCashback, you can earn cashback on your O2 free SIM.
Big Bundles Give You More For Your Money
O2's Big Bundles tariffs are ideal if you use your phone a lot and are looking to get more for your money. The best bit is there is no contract, meaning you can just top-up the required amount for the data, calls and texts you require.
You have the choice of five Big Bundles, which range in monthly cost from £10 to £30 — all of which include free O2 Wi-Fi and access to O2 Priority offers. You can opt for as little as 2GB of 4G data, 250 minutes and 1,000 texts right through to 20GB of data and 3,000 minutes and texts. As an added bonus you might be able to benefit from promotions that could give you increased allowances for the first month of your contract.
