What is a SIM Only deal?

A SIM Only deal offers you a bundle of minutes, text and data just like a standard mobile phone contract. However, the difference is that you don't get a smartphone you only get a SIM Card included which enables you to save a significant amount of money.

Why choose a SIM Only contract?

SIM Only plans have a number of advantages over standard phone contracts including;

  • Shorter Contract Lengths  - SIM Only contracts come with shorter contract lengths than standard mobile contracts. We offer SIMs on 1 month rolling contract or 12 month contracts. 
  • Keep your number - Transferring over your existing number is quick, free and easy. Follow the 3 simple steps on our Keep your number guide after your SIM arrives.
  • Keep your existing device  - Keep the exisiting phone you love and save money on your monthly cost while you wait example for a new smartphone to launch.
  • Great Value deals - SIM Only deals offer much better value than standard Pay As You Go and fully-fledged mobile contracts. That's because we don't have to give a share of their profit to the mobile manufacturers - so the savings are passed onto you the customers.

Why Choose Three SIM Only?

All SIM Only contracts and Pay As You Go SIMs come with a host of added extras that you won't get elsewhere including:

  • 4G at no extra cost  - All our SIM Only plans come with '4G at no extra cost'. In order to enjoy 4G you'll just need 4G ready phone when 4G isn't available you can still use our 3G network.
