Three's Terms and conditions.
 
You can read our full terms and conditions here but here are a few of the most important points you'll be agreeing to when you tick this box:
Each May, your monthly package price will increase by an amount up to the RPI rate, published in the February of that year.
Your monthly price includes a £5 monthly discount for paying by direct debit.
Your plan is made up of a number of 'units'. A unit entitles you to either one minute of calls, one text or one megabyte of data. On the back of your bill, you'll see the exact value of each unit within your standard allowances.
You will be charged for additional services you use outside of what is included with your allowance. These charges are set out in our Price Guide.
We may increase charges for standard Three services that you use once you've used up your units. If we think these changes are likely to be of material detriment to you, we'll give you notice of this, and you may be able to cancel your contract. We may also increase or introduce new charges for additional services or add-ons. We'll publish any changes on our website. You won't be able to end your agreement with us in these circumstances.
If you change your mind and want to return or exchange your device, please call us on 0333 300 0330 (standard charges apply) within 14 days from delivery of your new SIM and/or device. If you wish to exchange your device for a different make or model, a charge of £12.99 will apply. If you incur any charges (for example, call charges) during these 14 days you will be charged for those services and for any reduction in value of your device. You must not install “Find My iPhone” on your Apple device during the returns or exchanges period. If you do, and you fail to remove it before returning your device to us, we will reduce your refund or apply a charge to your Three account by an amount of up to £200. See our Returns and Exchange Policy for more details.
If you decide you want to cancel your agreement after 14 days and before the end of the minimum term of your contract, you’ll need to pay a cancellation fee (your remaining total monthly charges during the minimum term of your contract minus a variable discount, currently 20%
We can cancel your agreement in some circumstances for example when you don't pay your bills on time or where we reasonably believe you haven't complied with certain terms of your agreement.
