O2 Free Sims - Pay As You Go Sims

O2 Logo

If you don't use your phone very often, O2's classic pay as you go SIMS are the perfect option for you as they will allow you to top up when you want and only pay for what you use. Their classic 321 tariff will charge you 3p per minute, 2p per text message and 1p per MB used. The minimum top-up is £10, although you will benefit from free O2 Wi-Fi, which will allow you to save your data when you are out and about.

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 using the form at the bottom of this page, 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.
