Extra info
  1. Every 1 April, your Monthly Charge will increase by a fixed amount depending on your plan’s data allowance. Plans 4GB or less & Smartwatch Pairing Plans will increase by £1.80 per month. Plans from 5GB to 99GB will increase by £1.90 per month. Plans 100GB or over will increase by £2.30 per month. All Home Broadband plans will increase by £3.50 per month.
    Visit the price increase page
    for full details. Our systems work to very small fractions, and each charge is rounded up or down to make it easier to read. This means that there may be a small inconsistency to the price shown in your shopping basket, compared to the statement which shows the price rise that will apply during the Minimum Term of your Plan and your bill, which both show the actual amount you will be charged. For more information, please see our help and support pages or your Price Guide. Your monthly charge includes a £5 discount for paying by a recurring method, such as Direct Debit. The £5 monthly recurring payment discount and the annual price increase do not apply to Add-ons, out-of-allowance charges, Three Your Way device plan agreement repayments or Three Insurance premiums.Check out our
