Does iPhone Duo storage affect its value?
We value unlocked iPhone Duo models in 256GB, 512GB, 1TB and 2TB. Choose the capacity shown in your phone’s settings.
Can I sell a damaged iPhone Duo?
For cracked glass, battery faults or camera issues, send us the details for a manual valuation. A working-phone estimate is not a confirmed offer for a damaged handset.
Can I sell a network-locked iPhone Duo?
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 Apple Account, with Find My and Activation Lock removed 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 iPhone Duo?
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.
