What if you could earn money off your mobile bill just by doing your normal weekly shop? That is the premise behind Airtime (formerly known as Airtime Rewards), a free UK app that links your debit or credit card, tracks your spending at partner retailers automatically, and funnels the cashback straight towards your phone contract. No voucher codes, no receipt scanning, no clicking through to a cashback portal — it all happens in the background.
It sounds almost too easy. And for many people it genuinely is that simple. But as with any financial app that asks you to hand over card details, it is worth understanding exactly how it works before you sign up. This review covers the full picture: how card-linking technology works, which networks and retailers are supported, realistic savings, the referral scheme, security, drawbacks, and how Airtime stacks up against alternatives like TopCashback and Quidco.
What Is Airtime and How Does It Work?
Airtime is a free-to-download app available on iOS and Android. The concept is straightforward: you link up to 10 Visa or Mastercard debit or credit cards to your account, and whenever you spend at one of Airtime’s 200+ partner retailers using one of those linked cards, the purchase is automatically detected and a percentage of your spend is credited to your Airtime balance. Once your balance hits the minimum threshold, you can apply it as a credit directly against your monthly mobile phone bill.
The app was rebranded from “Airtime Rewards” to simply “Airtime” in 2024, though many users and review sites still use the original name. The core mechanic has not changed with the rebrand.
How Card-Linking Works (and Why It Is Not the Same as Open Banking)
Card-linking is a specific technology that is distinct from open banking. When you register a Visa or Mastercard with Airtime, the app works directly with those card networks to monitor transaction data. You do not share your PIN, your online banking password, or your card security code (the three or four digit CVV on the back). Airtime receives only a read-only view of transactions made at its partner retailers — it cannot see your full bank statement and it cannot initiate any payment on your behalf.
Airtime is an official partner of both Visa and Mastercard, and holds PCI Level 1 compliance — the highest tier of the Payment Card Industry Data Security Standard (PCI DSS). This is the same standard applied to major payment processors. Card data is encrypted and stored securely; you can remove any card from the app at any time, which permanently deletes that card data from their system. Airtime states it will never sell or share your data with third parties.
There is also an optional upgrade called Airtime Up, which adds Open Banking connectivity (via your bank rather than Visa/Mastercard networks). Airtime Up lowers the minimum redemption threshold from £10 to £5, clears rewards in one day rather than up to 90 days, and unlocks additional retailer offers and priority customer support. It is optional — the standard card-linking version works perfectly well without it.
Which Mobile Networks Are Supported?
This is one of the most important things to check before signing up, because Airtime only pays out as bill credit if your network is supported. As of June 2026, the supported networks are:
- Monthly contracts: EE, O2, Three, Vodafone
- Pay-as-you-go: EE, O2, Three, Vodafone, Giffgaff, Lebara Mobile
Notably, many of the so-called “virtual” networks (MVNOs) are not supported for direct bill credit. Networks including Asda Mobile, BT Mobile, iD Mobile, Plusnet Mobile, Sky Mobile, Smarty, Talkmobile, TalkTalk Mobile, Tesco Mobile, Virgin Mobile, Voxi, Lycamobile, and Now PAYG are all excluded. A change introduced in October 2025 means that if you were previously on a supported network and switch to an unsupported one, your ability to earn bill credit is removed.
If your network is not on the supported list, you are not entirely without options — you can still redeem your balance as gift cards or, with some redemption methods, as a withdrawal back to your card (though fees may apply). But the headline proposition of free money off your phone bill only works for customers on EE, O2, Three, or Vodafone. If you are considering switching to a cheaper SIM-only deal, it is worth reading our guide to the best SIM-only deals in the UK and how to cut your mobile bill before deciding.
Which Retailers Are on the App?
Airtime currently lists 200+ partner retailers where you can earn cashback automatically by paying with your linked card. These include well-known high street and online names such as Argos, Boots, Waterstones, Lego, and New Look, alongside many others across fashion, food, travel, and entertainment. The full list is visible in the app and changes over time as new brands join and others leave.
In addition, the app’s “Extras” section allows you to purchase gift cards for over 120 major retailers — including Sainsbury’s, ASDA, Primark, and JD Sports — and earn cashback on those purchases too, with rates reportedly reaching up to 37.5% on gift card buys via that tab. You can also book holidays through partners such as Jet2Holidays and purchase phone insurance through the app.
Realistic Earnings: How Much Can You Actually Save?
Cashback rates on everyday purchases typically range from 1% to 15%, with an average closer to 5% at most standard retailers. Time-limited boosted offers can push rates higher on specific brands. MoneySavingExpert describes it as “a hassle-free no-brainer” for most people, given that it costs nothing and requires no active effort.
In practice, how much you earn depends heavily on how many supported retailers you already shop with and how often. A family that regularly uses Boots, Argos, and a couple of fashion retailers could realistically accumulate £5 to £15 per month. Someone who shops mainly at supermarkets (which are largely absent from Airtime’s core list, though gift cards are available) may find earnings much lower — perhaps £1 to £3 per month. Heavy-spending households who maximise the gift card tab can do considerably better.
The standard minimum to redeem against your phone bill is £10. With Airtime Up the threshold drops to £5. Rewards can take up to 90 days to clear on the standard plan (one day with Airtime Up), so you will not see instant results in the early weeks.
| Network | Monthly contract supported? | PAYG supported? | Minimum to redeem |
|---|---|---|---|
| EE | Yes | Yes | £10 (£5 with Airtime Up) |
| O2 | Yes | Yes | £10 (£5 with Airtime Up) |
| Three | Yes | Yes | £10 (£5 with Airtime Up) |
| Vodafone | Yes | Yes | £10 (£5 with Airtime Up) |
| Giffgaff | No | Yes | £10 (£5 with Airtime Up) |
| Lebara Mobile | No | Yes | £10 (£5 with Airtime Up) |
| Sky Mobile, Tesco, iD, VOXI, others | No | No | Gift cards / withdraw only |
The Referral Scheme
Airtime has a referral programme. When you share your personal referral code with a friend, and they sign up and spend at least £5 at a partner retailer within one week of joining, you receive £5 in your Airtime balance and they receive a £2 bonus. This is a modest but genuine one-off reward. The referral code can be shared via the app; various third-party sites also publish codes for new sign-ups to use if they do not know an existing user.
Pros and Cons
Pros
- Fully automatic — no clicking through portals, no codes, no receipt scanning
- Free to use — the app costs nothing and there are no subscription fees on the standard plan
- Stackable with other cashback sites — MoneySavingExpert confirms you can use Airtime alongside TopCashback or Quidco for online purchases (in most cases)
- Strong security credentials — PCI Level 1 compliant, official Visa and Mastercard partner
- 200+ retailers — broad enough that most households will earn something
- Gift card option — useful if your network is unsupported
- Well-reviewed app — 4.7 out of 5 on the Apple App Store from over 40,000 reviews
Cons
- Limited network support — only EE, O2, Three, and Vodafone for monthly contracts; many MVNOs excluded
- Slow reward clearing — up to 90 days on the standard plan before you can redeem
- £10 minimum redemption — low earners may wait months to hit the threshold
- Fees for alternative redemptions — withdrawing to card or certain gift card redemptions may incur a charge (shown in-app at point of redemption)
- Retailer list changes — cashback rates and partners can be removed without notice
- Rates are modest — 1–5% on most everyday purchases is helpful but not transformative
- Card-linking requires trust — sharing card details with a third-party app may not suit everyone
How Does Airtime Compare to TopCashback, Quidco, and Bank Cashback?
Airtime is a different product to traditional cashback sites like TopCashback and Quidco. The key differences are:
- Activation: TopCashback and Quidco require you to click through their site or browser extension before each purchase. Airtime requires no activation — you just pay with your linked card.
- Retailer coverage: TopCashback and Quidco cover thousands of online retailers including many where Airtime has no presence (insurance, broadband, travel booking). Airtime’s strength is in-store spending.
- Stacking: Crucially, you can use Airtime at the same time as TopCashback or Quidco for online purchases. If you click through via Quidco to buy something online and pay with a card linked to Airtime, you can earn cashback from both simultaneously — a powerful combination.
- Bank cashback offers: Some current accounts (Chase, Amex, certain Barclays accounts) offer their own card-linked cashback. These are similar in mechanism to Airtime but the rewards go to your bank account rather than your phone bill. They are worth stacking where possible too.
The sensible strategy for most people is to use Airtime alongside other cashback tools rather than instead of them. The marginal effort is near zero once your cards are linked.

Frequently Asked Questions
Is Airtime safe to use?
Yes, within reasonable parameters. Airtime holds PCI Level 1 compliance — the highest grade available — and is an official partner of Visa and Mastercard. You do not share your PIN, online banking login, or card CVV. The company only sees transaction data from its own partner retailers, not your full bank statement. You can remove any linked card at any time and all associated data is deleted. That said, you are sharing financial data with a third-party company, which is a matter of personal preference. The app has been operating since 2014 with no publicly known data breaches.
Can I use Airtime if I am not on EE, O2, Vodafone, or Three?
You can still sign up and earn cashback, but you will not be able to redeem it directly against your phone bill. Alternative redemption options include purchasing gift cards from over 120 retailers via the app’s Extras section, or withdrawing to card (though fees may apply on alternative redemption methods — these are disclosed in-app before you confirm). If saving on your mobile bill is your primary goal, it is worth considering whether switching to one of the four supported big networks might make sense for you. Our SIM-only deals guide covers current market options.
Can I use Airtime at the same time as TopCashback or Quidco?
In most cases, yes. MoneySavingExpert explicitly notes that Airtime can be used alongside traditional cashback sites. If you click through to an online retailer via TopCashback or Quidco and then pay with a card linked to Airtime, you can earn cashback from both services simultaneously. This stacking approach is legal and is a popular tactic among deal hunters. As always, double-check individual retailer terms as a small number may have exclusions.
How long does it take for cashback to appear?
On the standard free plan, rewards can take up to 90 days to clear and become available for redemption. This is because Airtime waits for the retailer’s return window to pass before confirming the transaction. With the optional Airtime Up upgrade (which connects via Open Banking), this drops to as little as one day. The trade-off is that Airtime Up requires you to share more financial data via Open Banking.
What is the sign-up bonus and referral reward?
New users who sign up with a referral code from an existing member typically receive a £2 bonus credited to their account once they make a qualifying purchase (spending at least £5 at a partner retailer within one week of joining). The referring member receives £5. Sign-up bonuses and referral amounts do change periodically, so verify the current offer within the app at the time you sign up.
Is Airtime Worth It?
For most people on EE, O2, Three, or Vodafone contracts, the answer is a straightforward yes — as long as you go in with realistic expectations. Airtime is not going to wipe out your phone bill or replace your need to check cashback sites for big purchases. What it does do is quietly accumulate small sums in the background, with zero ongoing effort after the initial setup. Over a year, even a modest earner could see £20 to £60 knocked off their mobile costs.
The caveats are worth keeping in mind. Redemption is slow on the free plan, your network must be supported, and you are sharing card transaction data with a third party. None of those are dealbreakers for most users, but they are factors worth weighing. If you are uncomfortable with card-linking as a concept, the app is not for you. If you are already on a big-four network and want a hands-off way to trim your phone bill, it is hard to find a reason not to sign up.
The smartest approach is to use Airtime as one layer of a broader cashback strategy: link your cards to Airtime, also sign up to at least one traditional cashback site, and consider whether your bank offers any card cashback of its own. Stack all three and the savings add up meaningfully over time.
This article is for general information only and does not constitute financial advice. Network support, cashback rates, redemption thresholds, and retailer availability are correct to the best of our knowledge as of June 2026 but are subject to change — always check the current terms within the Airtime app before signing up or redeeming rewards.
