The Three referral code that's worth up to £80
Mobile contracts are one of the few things most of us buy every couple of years without shopping around properly, which is exactly why a Three referral code is worth using if you or a friend are already planning to switch. Three's refer-a-friend scheme pays out real cash, not a token gift card, for successful referrals on selected Pay Monthly and SIM Only deals.
What is Three?
Three is one of the UK's four major mobile network operators, alongside EE, O2 and Vodafone, known historically for unlimited data plans and competitive SIM Only pricing. It offers Pay Monthly phone contracts, SIM Only plans, Mobile Broadband and tablet data plans, and has increasingly focused on 5G coverage as a selling point. Three is owned by CK Hutchison and has been through merger discussions with Vodafone UK in recent years as the mobile market consolidates, though it continues to operate and sign up new customers as a standalone brand.
How the Three referral code works
- Head to three.co.uk/refer-a-friend and register with your email address.
- Three sends you a unique referral link to share with friends via email or social media.
- Your friend clicks the link and signs up for a qualifying Pay Monthly phone, SIM Only plan, tablet contract or Mobile Broadband deal.
- Once your friend's contract is confirmed and active, the referral is verified.
- Cash rewards, up to £80 combined, are paid out and split between you and your friend according to the current offer terms.
What you and your friend get
Three has specifically marketed this as cash rather than store credit or a gift card with an expiry date, which makes it more flexible than many rival schemes.
Eligibility, timing and the small print
Not every Three deal necessarily qualifies for the referral reward — check the current list of eligible Pay Monthly, SIM Only, tablet and Mobile Broadband products on Three's own refer-a-friend page. Your friend needs to be a genuinely new Three customer, and the reward is paid once the new contract is confirmed and active rather than immediately at sign-up. As with most telecom referral schemes, cancelling the new contract early can affect whether the reward is paid or clawed back.
Using Three well
If you're comparing Three against other networks, check current 5G coverage in your specific area rather than relying on national coverage claims, since network strength varies by postcode. SIM Only deals are usually the best value if you already own a decent phone, while Pay Monthly contracts make more sense if you need a new handset spread over instalments. Three also runs its own Connect Together discount for adding multiple people to one account, which is worth comparing against individual referral-driven sign-ups if you and a friend are switching together.
Pros and cons
- Pro: Genuine cash reward, not a restrictive gift card.
- Pro: Reward can reach up to £80 combined for phone contracts.
- Pro: No apparent limit on how many friends you can refer.
- Con: Not every deal on the site qualifies for the referral bonus.
- Con: Reward isn't paid until the new contract is confirmed and active.
- Con: Coverage can be patchy in some areas compared with rival networks.
Tips to make the reward land
Make sure your friend actually signs up through your personal referral link rather than going direct to Three's site, since that's the only way the referral is tracked. Check the qualifying product list before your friend picks a plan, and keep a record of the sign-up date in case you need to query a missing reward with Three's customer service.
Alternatives worth comparing
EE, O2 and Vodafone all run their own occasional referral or incentive schemes, and it's worth comparing network coverage and SIM Only pricing across all four before committing purely on the basis of a referral bonus. Smaller MVNOs like giffgaff and Smarty can also undercut the big four on SIM Only pricing, though they don't typically offer cash referral rewards of this size.
Verdict
A Three referral code is genuinely worth using if you or a friend are already planning to switch networks, since the reward is real cash rather than a gimmick. Just check which specific deal you're taking out qualifies for the higher end of the reward before assuming you'll get the full £80.
