If you're already on SMARTY and happy with your rolling SIM-only plan, the SMARTY referral scheme is a genuinely simple way to turn word-of-mouth into real money. Share your unique referral link with a friend, they pick a plan that suits their data needs, and once their SIM renews for a third month you both walk away with a reward worth up to £20 to spend at Amazon, John Lewis & Partners, Uber or via PayPal.
There's no cap on how many friends you can refer, no fixed-term contract for the new customer to worry about, and no complicated code to remember — just a personal link generated from your SMARTY dashboard. For anyone who's already recommending SMARTY's cheap, flexible SIM-only plans to friends and family, this SMARTY referral programme simply rewards you both for something you'd likely be doing anyway.
Below is everything you need to know about what the new customer receives, how the reward tiers work, how to activate a referral correctly, and how SMARTY as a network actually stacks up day to day.
What the new customer gets: A new SMARTY customer who joins via a referral link and stays active until their plan renews into the third month unlocks a reward of £5, £10 or £20 (paid to both the referrer and the new joiner) as a gift card for Amazon.co.uk, John Lewis & Partners, Uber, or as a PayPal reward.
Referral code: No traditional code is required — SMARTY uses a personal referral link generated in the existing customer's dashboard instead.

How to activate: The new customer must sign up for a SMARTY plan via the referral link (or a physical referral SIM), activate it, and remain an active, legitimate SMARTY user without pauses or cancellation through to their qualifying renewal.
Qualifying criteria: The new customer must be a genuine UK resident aged 18+ who has never been a SMARTY customer before. Reward value depends on the monthly plan price they choose at the point their reward qualifies.
Timing: The reward is confirmed on the Qualifying Acceptance Date — broadly, the point at which the new customer's plan has renewed into its third billing month — and both parties receive a reward-choice email from SMARTY's partner Buyapowa within 30 days of that date.

How to activate the SMARTY referral offer
- An existing SMARTY customer logs into their SMARTY dashboard and activates their own plan first, since a live plan is required before referring anyone.
- They generate their personal referral link from the Refer a Friend page and share it directly with a friend or family member — not posted publicly to strangers.
- The friend clicks the referral link, browses SMARTY's plans, and chooses whichever monthly plan suits their data needs.
- The friend completes sign-up, receives their SIM (physical or eSIM), and activates it in their device.
- Both the existing customer and the new joiner keep their SMARTY plans active, with auto-renew switched on, right through to the new joiner's second renewal.
- Once the new joiner's plan has successfully renewed into its third billing month, the referral becomes a Qualifying Acceptance.
- Within 30 days, both people receive an email from Buyapowa (SMARTY's referral partner) inviting them to choose their reward: Amazon, John Lewis & Partners, Uber, or PayPal.
SMARTY Mobile review: what you're actually signing up for
SMARTY is a SIM-only mobile network owned by Three UK, built around simple, rolling monthly plans with no credit checks, no loyalty penalty and no 24-month lock-in. Its entire pitch is transparency: the plan you see is the plan you get, whether you've been a customer for a week or five years.
Plans and data allowances
- Entry-level plans start around £6 a month for 5GB of data with unlimited calls and texts.
- Mid-range options include 20GB (£9), 40GB (£10) and 150GB (£15) plans.
- Bigger data users can choose 200GB (£17) or a genuinely unlimited data plan (£20).
- Occasional promotional plans (such as time-limited boosted-data offers) appear from time to time, each with their own separate terms.
Onboarding and app experience
Signing up is done entirely online or via the SMARTY app, with an eSIM option for compatible phones as well as physical SIMs posted out. The app is where most customers manage everything day to day: checking data usage, switching plans, adding data top-ups, and setting up or tracking a referral.
Pricing, fees and delivery
SMARTY plans are billed monthly with no upfront device cost, since it's a SIM-only service — customers bring their own phone. There's no early exit fee because plans roll month to month; customers give 30 days' notice to leave or downgrade. SIMs are typically delivered within a few working days of ordering, and eSIMs can often be activated the same day.
Rewards and loyalty mechanics
Beyond the referral scheme, SMARTY doesn't run a points-based loyalty programme — its main incentive structure for existing customers is the ability to refer unlimited friends and earn tiered rewards each time. The tiering (£5 / £10 / £20) means the reward scales with how much the new customer ends up spending monthly, so bigger plans mean bigger rewards for both sides.
Support and account management
Customer support runs through the app, online help centre and social channels, with no traditional phone-based call centre for routine queries — a trade-off some customers appreciate for speed and some find limiting if they prefer speaking to someone directly.
Security and eligibility
To take part in the referral programme, the existing customer must have complied with SMARTY's standard terms and conditions, and the new joiner must be a genuine UK resident aged 18 or over who has never previously held a SMARTY plan. SMARTY explicitly reserves the right to withhold or claw back rewards where referrals look automated, fraudulent, or are mass-distributed to strangers rather than personal contacts.
Limitations worth knowing
- The reward isn't instant — it only confirms once the new joiner has renewed into their third billing month, so referrers need a little patience.
- Smaller, cheaper plans only unlock the £5 tier, so the headline £20 reward requires the friend to choose a plan of £15 a month or more.
- Physical SIM referrals are capped at two per month, though digital referral links can be shared without limit.
- As a SIM-only network, SMARTY doesn't sell handsets, so it won't suit anyone wanting a new phone bundled with their plan.
Practical scenarios for the SMARTY referral
- Scenario — light data user: A friend who mostly uses Wi-Fi and just wants calls and texts might choose the £6, 5GB plan, which qualifies both people for a £5 reward once it renews into month three.
- Scenario — streaming and social media user: A friend picking the 150GB plan at £15 a month unlocks the full £20 reward tier for both the referrer and the new customer.
- Scenario — household switching multiple lines: Someone referring several family members individually can earn a separate reward for each Qualifying Acceptance, since there's no cap on the number of friends referred.
- Scenario — someone who cancels early: If the new customer pauses or cancels their plan before the third-month renewal, the referral won't qualify and no reward is issued to either party.
Comparing SMARTY's plan tiers
| Plan | Monthly price | Data allowance | Referral reward tier if chosen by a new joiner |
|---|---|---|---|
| 5GB plan | £6 | 5GB | £5 reward |
| 20GB plan | £9 | 20GB | £5 reward |
| 40GB plan | £10 | 40GB | £10 reward |
| 150GB plan | £15 | 150GB | £20 reward |
| 200GB plan | £17 | 200GB | £20 reward |
| Unlimited data plan | £20 | Unlimited | £20 reward |
Who the SMARTY referral suits best
- Existing SMARTY customers who already recommend the network to friends and want to be rewarded for doing so, rather than referring informally for nothing.
- Value-conscious switchers who want a no-contract SIM-only plan on the reliable Three network, without being tied into a lengthy agreement.
- Households with multiple phone contracts looking to move several lines across at once, since each successful referral pays out separately.
- Anyone choosing a mid-to-large data plan anyway, since picking a £15+ plan naturally unlocks the top £20 reward tier without needing to overspend purely to chase the bonus.
Referral FAQs
How much can I earn from the SMARTY referral?
Up to £20 for you and up to £20 for your friend, depending on the monthly price of the plan your friend chooses when they join.
Is there a SMARTY referral code?
No. SMARTY doesn't use an alphanumeric referral code — you share a personal referral link generated in your account dashboard instead.
How many friends can I refer to SMARTY?
As many as you like, provided each is a genuine personal contact rather than a stranger, and you're not mass-distributing your link publicly.
When does the referral reward actually pay out?
Once your friend's plan has renewed into its third billing month without any pause or cancellation, both of you receive an email from Buyapowa within 30 days to choose your reward.
What can the reward be spent on?
You can choose an Amazon.co.uk gift card, a John Lewis & Partners gift card (which also covers Waitrose), an Uber voucher (including Uber Eats), or a PayPal reward.
Do I need to already be a SMARTY customer to refer someone?
Yes, you must have an active SMARTY plan of your own before you can generate a referral link and refer a friend.
Can I send a physical SIM instead of a digital link?
Yes, but physical referral SIMs are limited to two per month, whereas digital referral links can be shared without limit.
What happens if my friend cancels their plan early?
If they cancel or pause before their qualifying renewal, the referral won't be treated as a Qualifying Acceptance and neither of you will receive a reward.
Verdict
The SMARTY referral scheme is a straightforward, generous way to earn while helping friends switch to a genuinely flexible, no-contract mobile plan. With rewards scaling up to £20 for both sides, no limit on how many friends you can refer, and a choice of well-known reward options, it's one of the more rounded referral programmes among UK SIM-only networks — the only real ask is a little patience while the new customer's plan renews into month three.
