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.
