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.
  • 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?

  • 4G at no extra cost - Three will launch their 4G network in December and all customers will be upgrade to 4G at no extra cost. No hefty price tag. No extra charges. No expensive new phones or contracts. And no fuss.
  • Unlimited data - Three are the network 'built-for-internetting' and the majority of their tariffs come with unlimited Ultrafast 3G data. They will also be the only network in the UK offering unlimited 4G data!
  • Great value - Three aim to provide the best value contracts of any mobile operator in the UK. That includes pay monthly handsets, pay as you go, mobile broadband and SIM only plans.
