How much is my Samsung Galaxy S25 worth?
The standard S25 is a high-volume handset with an active used market, which keeps valuations competitive. Because so many are sold on contract, network lock status is worth confirming before you request a figure.
- Storage tier (128GB, 256GB or 512GB)
- AMOLED condition and touch response
- Battery condition and charging behaviour
- Network unlocked or carrier locked
Does Galaxy S25 storage affect its value?
We buy the Galaxy S25 in 128GB, 256GB and 512GB. The 128GB model is the most common on the used market, so larger capacities stand out when we price them.
Can I sell a damaged Galaxy S25?
Yes. Cracked screens, damaged backs, camera faults and worn batteries are all bought — including handsets that no longer switch on.
Can I sell a network-locked Galaxy S25?
A network lock is not a problem — carrier-locked handsets are still bought, and UK networks unlock free of charge on request. An account lock is different: the device must be signed out of the previous owner's Samsung and Google accounts, with Factory Reset Protection cleared through official methods. We never bypass security and we do not buy devices reported lost or stolen. Phone locks explained.
Where can I sell my Galaxy S25?
Post it to us from anywhere in the UK, or sell it in person at 41 Church Street, St Helens, WA10 1AX or 48 Lowther Street, Carlisle, CA3 8DP. Both counters are open Mon–Sat 9:30am–5:30pm · Sun 10:00am–4:00pm. Bring valid photo ID — it is required for every second-hand purchase.
Every valuation is confirmed after we have inspected and tested the handset. We never quote a final price sight unseen, and you are free to walk away at any point.
