Referral voucher · Cashback
£2 credit
Join Airtime with a referral code and get £2 of mobile bill credit once you link a card and spend £5 in your first week.

Airtime (formerly Airtime Rewards) turns everyday card spending into mobile phone credit rather than a bank transfer or gift card — link a debit or credit card in the app, shop as normal at any of its 200-plus partner retailers, and a slice of what you spend comes back as credit on your EE, O2, Vodafone, Three or other supported mobile bill. There's nothing to click through before shopping; once a card is linked, qualifying purchases track automatically in the background. The referral bonus is a fast way to get started: sign up with a friend's code, link a card and spend £5 within your first week, and you get £2 credit immediately while your friend earns £5 for referring you. After that first bonus, ongoing cashback rates vary by retailer, typically running from 1% to 15%.
