At a glance. The Apple iPhone 18 Pro Max is currently sold on contract by Fonehouse, Mozillion, O2 and iD Mobile, with airtime from Mozillion, O2, Talkmobile, Three, Vodafone and iD Mobile. It is available in 4 storage sizes (256GB, 512GB, 1TB, 2TB); larger sizes add to the price, so pick the smallest you can live with. The cheapest deal by effective monthly cost is £62.31 a month with £30.00 upfront over 36 months on O2, which works out at about £55.14 a month all in. If you would rather buy it outright, the lowest SIM-free price we track is £1,290 from Mozillion — worth comparing against the contracts above, paired with a SIM-only plan. Key specs: 6.9" super retina xdr oled, a Apple A20 Pro (2 nm) chip, IP68 water resistance.
