What do I do if my Three promo code doesn’t work?

We test all our Three voucher codes to ensure they work as supposed to. However, if your total isn’t discounted after entering your code, follow the steps below to solve the problem.

  • Check whether there was a particular product or subscription package to qualify for the offer.

  • Check that your voucher hasn’t expired. Look at your code’s use-by date on Voucherbox.

  • Check that you’ve entered your Three code exactly as it’s shown on Voucherbox. If it has typos, it won’t work.

  • Ensure you've met the minimum purchase amount.
