Why choose SIM-Only?
Keep the Phone You Love
We say if it ain't broke, don't fix it. Keeping your phone saves you both money and hassle, and Three will even help you keep your old number, too.
Plans for Full Flexibility
Whether you’re searching for smart savings on your phone deal, or you’re looking to get your fill with All-you-can-eat data, we’ve got the perfect package for you.
No lengthy Commitments
Our 30 day and 12 month SIM-Only contracts are great if you don’t want to be tied down to a lengthy 24 month commitment.
Feel At Home
Use your allowance to call and text the UK and use your data without paying a penny more in any of our 18 selected countries.
