Pay As You Go

Find the right tariff for you

Live big with one of our Pay As You Go sim only tariffs – they each give you something different and you can even switch tariff once a month if you want to. For free. Plus you'll also get access to perks like Priority and O2 Wifi.

If you need a phone as well, check out our Pay As You Go phones. And if you're already on Pay As You Go, you can sign in to My O2 or call 2202 to switch to a new tariff - there's no need to order a new sim.

Big Bundles

How big do you want to live? Choose one of our data, texts and minutes packages, starting from £10 a month. Remember to top up the right amount each month – we'll then exchange the credit for your chosen Big Bundle which will last for exactly a month.

Your Big Bundle allowance will automatically renew on the same day every month, as long as you've got enough credit to cover the payment.

If you’ve got credit left, but not enough for a Big Bundle, you'll still be able to call, text and use data at our standard rates until it's all gone. During this time, if you top up the right amount of credit, you'll get your bundle allowance back and will no longer be charged at our standard rates.
