Frequently asked questions

What is a SIM Only plan?

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.

What are the benefits of SIM Only deals?

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

  • Shorter Contract Lengths - SIM plans are available on 1 month rolling contract or 12 month contracts compared to the 24 month plans that come with phones.
  • 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 phone - Keep your existing phone and save money on your monthly cost. Perfect if you are happy with your current device, or are waiting 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 Three 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?

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

  • Free 4G for all  - All 3 SIM Only plans come with '4G at no extra cost'. If you don't have a 4G phone or arn't in a coverage area don't worry you'll still be able to use Three's 3G network.
  • Free Roaming Abroad - Use your minutes, text and data abroad at no extra cost in 19 Feel At Home destinations, which now include Spain and New Zealand.
  • Free 0800 Calls  - Contract SIM plans on 3 come with free calls to 0800 numbers!
  • Unlimited data  - Truly unlimited data plans on Three with no catches.
  • Tethering included  - Contract SIM Only plans come with tethering included enabling you to share your data with other devices using a personal hotspot. You can now use up to 12GB tethering per month!

What's so great about Pay As You Go SIM Cards?

Pay As You Go SIMs offer even more flexibility than a SIM Only contract and come with low rates that don't expire, just 3p per minute, 2p per text and 1p per MB of data. And you'll still get a host of extras on Three including 4G at no extra cost and free roaming abroad. Three will even send you text alerts when your balance is getting low. Choose from one of the PAYG bundles above, or order a free sim.

Do Three's SIM Cards also support 4G?

All SIM deals come with a SIM card that supports 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 you are not you'll automatically roll back onto the 3G network.

Does Three really offer unlimited data SIM Cards?

Yes, SIM Cards with truly unlimited data are available with no catches on Three from £20 a month. They are perfect for those who are always browsing the web on the move. All unlimited data plans on 3 come with 4G at no extra cost, along with tethering included and free roaming abroad in 18 countries.

Is tethering included?

Yes tethering is included with all 3 Pay Monthly SIM plans. The only restriction is that those with unlimited data can only use a maximum of 12GB per month tethering and tethering isn't included on Three Pay As You Go.
