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?

There are a number of reasons to choose to go SIM Only:

  • Shorter Contract Lengths  - SIM Only contracts come with shorter contract lengths than standard mobile contracts. We offer SIM Only deals 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 guide here.
  • Keep your existing smartphone  - When you come to the end of your contract you can choose to switch to SIM-Only to keep your existing smartphone. This saves money and also gives more flexibility on when to upgrade - for example, you may be waiting for a new smartphone to launch.
  • Great Value - SIM Only contracts offer much better value than standard Pay As You Go and , in many cases , better than a fully-fledged mobile contract. The operators don't have to give a share of their profit to the mobile manufacturers - with the savings then passed onto customers.

Why Choose Three SIM Only?

  • 4G at no extra cost  - All our 3G SIMs 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.
  • Feel At Home - Use your minutes, text and data abroad at no extra cost in 16 Feel At Home destinations. With Spain and New Zealand being added in April. Those on Pay As You Go will need to convert their credit to an add-on.
  • Free 0800 Calls  - Contract SIM plans come with free calls to 0800 numbers.
  • No nastly Pay Monthly price hikes - The price you pay when you take out your contract will change for the duration of your contract and won't change unless you transfer to a different tariff.
  • Unlimited data  - We offer SIMs with unlimited data so you surf the web and stream videos to your hearts content.
  • Tethering included  - Our contract SIM deals come with tethering included enabling you to share your data with other devices using your smartphone. Please note that on our unlimited data SIM Only deals you can only tether up to 4GB per month.

Pay As You Go SIM

Pay As You Go SIMs offer even more flexibility than a SIM Only contract and come with low Pay As You Go rates that don't expire, just 3p per minute, 2p per text and 1p per MB of data. All 3 Pay As You Go SIMs come with 4G at no extra cost and those who take out a PAYG bundle can use their device abroad at no extra cost with Feel At Home.

3G SIMs with 4G at no extra cost

All of our SIM deals come with a SIM card that support both 3G and 4G networks. The best news of all is that every customer gets 4G at no extra cost. All you need is a 4G ready phone and you'll automatically connect to the 4G network when in a coverage area and when not you'll roll back onto our Ultrafast 3G network.
