O2 Promo Codes - May 2024

23 O2 discount codes for phones & SIM only deals in the UK

Discount Codes Last Tested: 16 May, 2024

Steve Hogarty, tech writer, says: “One of the UK’s biggest mobile networks, O2 offers a frankly dazzling range of customisable contracts on the latest new phones, as well as a raft of SIM only deals and a regular online storefront where you can buy the newest tech accessories. As IndyBest’s tech writer and a city break addict, I find that O2 has the edge over other major networks when it comes to EU roaming – there’s no extra charge up to 25GB – and its add-ons and extras include unique benefits like priority tickets and perks at O2 venues. To get the best prices, check out our O2 voucher codes below.”
