Pay & Go

Find the right tariff for you

Live big with one of our Pay & 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 & Go phones. And if you're already an O2 Pay & Go customer, you can sign in to My O2 to switch to a new Pay & Go tariff.
