Yes. We buy the Samsung Galaxy S25 Ultra in any condition — cracked screen, faulty battery, water damage, or won't power on. Select the matching condition when quoting and you still receive a guaranteed offer rather than a £0 valuation.
Devices received and inspected before 2pm are paid the same working day by UK bank transfer (PayPal also available). Postage is free via a prepaid label, so the typical end-to-end time is 2–3 working days.
