So you don't need a new phone or an expensive contract, but you would rather have the preferable deals and security that you can usually get on network contract tariffs, rather than switching to Pay As You Go

Then you need a sim-only contract.

These are exactly what they say they are, just like a mobile phone contract but without the phone. 

Just like Pay As You Go you can select from a choice of competitive tariffs, but you'll generally get much more for your money than you get with Pay As You Go. 

If you want to replace your phone it also means that you can buy one that your favourite network may not offer, without leaving the network.

Why choose a sim-only deal?

  • Pay automatically each month - no need to top up
  • Cap your spend level
  • Never be without top up credit
  • Generally you get more for your money (than on Pay As You Go)
  • Keep your existing phone, or buy one of your choice
  • Easily switch tariffs if you need more (or less) data
  • You'll often get free extras such as 6 months Disney Plus or Apple Music


Just click the green "Go to Offer" button to see O2's latest contract deals. 

And don't worry, it's totally secure as your contract will be directly with O2. Clicking the button only takes you to O2's current offers and is always up to date. It does not commit you to anything. 

Not for you? 

Remember we have a huge range of UK Pay As You Go sim cards and tariffs, including all the major UK networks (O2, Vodafone, EE, Three), as well as Giff Gaff, Smarty, Voxi, Lebara and Lyca.
