Airtime Rewards is a cashback app. Itâs passive cashback insomuch as you link your credit/debit card(s) and when you spend at any of its over 150 retailers you are rewarded with typically 1% to 15% cashback. For example, I currently have 10% off at Greggs, 7% at New Look, and 3% at John Lewis/Waitrose. You can even use TopCashback/Quidco/etc to get additional cashback
Unlike other cashback sites, the cashback is paid in the form of credit off your mobile bill including O2, Three, EE, giffgaff and Vodafone.
