At a glance. The Samsung Galaxy S25 Edge is currently sold on contract by Fonehouse, Mozillion and O2, with airtime from Mozillion, O2 and Three. It is available in 2 storage sizes (256GB, 512GB); larger sizes add to the price, so pick the smallest you can live with. The cheapest deal by effective monthly cost is £25.79 a month with £29.00 upfront over 24 months on Mozillion, which works out at about £27.00 a month all in. If you would rather buy it outright, the lowest SIM-free price we track is £530 from Mozillion — worth comparing against the contracts above, paired with a SIM-only plan. 48 of the deals are for refurbished handsets, which are usually noticeably cheaper; use the condition filter to compare new and refurbished separately. Key specs: 6.7" dynamic amoled 2x, a Qualcomm SM8750-3-AB Snapdragon 8 Elite (3 nm) chip, IP68 water resistance.
