With an O2 contract, you just need to pay a small amount monthly. For example, with £25 a month, you can get 200 minutes of talk time and 200 text messages. Should you find yourself in need of more talk time or texts, you can pay £30 a month and get 400 minutes of talk time plus 500 texts.
If you like to be flexible and in control of your own mobile plan, O2 phone offers also come in pay and go packages. With pay and go, you can top up any amount you like according to your budget and of course each top up tier has its own tariff for calls and texts. The best thing about pay and go is you are in control and there is no string attached. Unlimited Free Texts has more O2 phone offers for you to choose and you get to pick the best deal offering free and unlimited texts.
