About Three Mobile

Started in 2003, Three Mobile is one of the UK's largest mobile networks, with 99% of the UK population using 3G and 4G and expanding 5G in major cities. Three Mobile provides SIM only deals, pay monthly phones, mobile broadband and data only deals. Customers can shop flexible contract lengths and data bundles, with unlimited data options available. You'll also find a customer portal and app to track usage, upgrade devices and add features. Three stocks a huge range of handsets, from Apple to Samsung and Google. With great prices and regularly updated online deals, Three helps customers stay connected without breaking the bank.

How Do I Apply a Promo Code on Three Mobile During Checkout?

  1. Choose a plan or device: Head to three.co.uk and select a product, such as a '12-month SIM Only plan' or a 'Pay Monthly' phone, like the Samsung Galaxy S24. Click 'Add to Basket' on the product page to get started.
  2. Basket and checkout: On the 'Your Basket' page, click the 'Go to Checkout' button in the bottom right corner.
  3. Apply promo code: In the checkout process, scroll down to the 'Promo code' section underneath the order summary. Click the 'Add a promo code' link to reveal the input field. Paste a valid code from DontPayFull and click 'Apply'.
  4. Place your order: Next, you need to enter your personal, delivery and payment details, and then click 'Place Order' to pay.

Why is my Three Mobile discount code not working?

If your Three Mobile discount code isn't working, there are a couple of reasons this could be the case. Codes have certain terms regarding the type of contract, the type of device or being a current customer. By double checking these, you should be able to apply a working discount, successfully.

  • Determine whether the code is for new or existing customers: Three Mobile run offers for new customers who sign a contract, whilst others are for existing customers who need to upgrade their plan. Make sure the code is appropriate for your customer type.
  • Check device or plan compatibility: Discount codes only work with selected smartphones, SIM only plans or broadband deals. A code for a Samsung Galaxy deal will not work if you are buying an iPhone.
  • Check that the minimum spend is satisfied: Certain deals have a minimum spend requirement before the discount comes into effect. If your order total is close to the threshold, it may be worth adding a small accessory or upgrading your data plan.
  • Determine if the code is case sensitive: Apply the code exactly as written, including any uppercase or lowercase letters. A minor mistake can lead to the code being missed.
  • Check expiration dates and usage limits: If the code has expired or has a limit on redemptions, the code will no longer work. If the code was working before but has since stopped working, then it has reached its limit.

If the code doesn't work, you can always try another code from our page. We regularly update our deals, so checking back in a few days might lead you to a new code that is better suited to your purchase.

Three Mobile Promo Code FAQ and Discount Guide

Can you use a Three Mobile promo code with their Refer a Friend scheme?

No, you can't use a promo code with the Refer a Friend scheme. The £25 prepaid Mastercard reward that both parties receive is only paid out when the friend signs up through the referral link without using other promotional offers.

Are there any specific SIM-only discount codes at Three Mobile?

SIM-only plans typically feature special discount codes with up to 50% off for the first 6 months. They work on 12-month or 24-month contracts and are updated monthly.

Does Three Mobile provide student discount codes?

Yes, students can save up to 20% on selected plans with Student Beans or UNiDAYS. These codes are verified and cannot be used with other codes.

How can I get early access to Three Mobile promo codes?

Subscribing to their newsletter allows you to access limited-time codes earlier, especially during seasonal events such as Black Friday and Back to School. Newsletter sign-ups provide 24-hour advance access to these deals.

Are there any special codes for Pay As You Go bundles?

Yes, PAYG bundle codes can sometimes come free, either as a data boost (e.g., 10GB extra) or £5 off when you top up £20 or more. These codes are temporary and linked to seasonal promotions.

Can I use more than one Three Mobile discount code at a time?

No, you can only use one promotional code at checkout. You will need to select the code that gives you the best value for your order.

Where can I find genuine and active Three Mobile discount codes?

We screen and check codes on this page at DontPayFull. Each code is tested against the plan type, length of time and minimum spend.

Does Three Mobile provide NHS or key worker discounts?

Absolutely, key workers such as NHS staff and more can enjoy up to 25% off selected plans. Verification is done via Blue Light Card, and these discounts cannot be used in conjunction with other codes.
