Advantages of SIM Only?

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 - because the operator doesn't have to re-coup the cost of the smartphone. Infact, you can pickup SIM Only deals on a 1 month rolling contract or 12 month contracts. Or you can choose one of our Pay As You Go SIMs for ultimate flexibility.
  • 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 SIMs come with '4G at no extra cost'. In order to do so you'll need a 4G ready phone and fear not 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 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 - Pay monthly SIM plans come with free calls to 0800 and 084 and 087 numbers cost just 5p per minute.
  • Unlimited Texts - All our SIM plans now come with unlimited texts.
  • Unlimited data - We offer unlimited data meaning you can browse with no worries about going over your monthly allowance.
  • Great value - Our plans start at just £7 a month leaving you with more money to spend on other things. 
  • Tethering - On our Pay Monthly plans you'll be able to share your data with other devices enabling you to connect multiple devices through your smartphone. Unlimited plans can only other up to 4GB per month.
