    We'll match or beat CeX

    Already have a CeX cash price for your iPhone 18 Pro Max? Send us their current cash offer and we'll match or beat it on eligible like-for-like devices.

    We'll match or beat CeX's current cash price on eligible like-for-like devices. Like-for-like means the same model, the same storage capacity, an equivalent condition or grade, the same working status, the same network or unlocked status where relevant, and a current verifiable CeX cash price (the cash figure, not the higher voucher value). Final valuation follows inspection. Terms apply.

    PhonesForCash is not affiliated with, endorsed by, partnered with or operated by CeX. CeX is named only as an identifiable competitor for the purpose of the comparison.

    How much is my iPhone 18 Pro Max worth?

    The Pro Max is consistently the most in-demand iPhone on the resale market, and the newest one commands the highest offers we make on any Apple handset. Because the value is high, we assess it carefully: screen and frame condition, battery health and whether any part has been replaced all count. A clean, boxed example with a healthy battery is worth meaningfully more than a scuffed one.

    • Storage tier (256GB up to 2TB)
    • Display condition across the larger panel
    • Battery health and any Service message
    • Rear glass and camera housing condition

    Does iPhone 18 Pro Max storage affect its value?

    We value the iPhone 18 Pro Max in 256GB, 512GB, 1TB and 2TB. High-capacity Pro Max handsets are the hardest variant to buy second-hand, so if yours is 1TB or 2TB it is worth telling us up front — it is one of the biggest single factors on this model.

    Can I sell a damaged iPhone 18 Pro Max?

    We buy damaged iPhone 18 Pro Max handsets, including cracked front or rear glass and non-working cameras. The large display makes screen damage the most expensive fault to correct on this model, so an accurate description of the crack (hairline, spidered, touch working or not) gives you the most accurate valuation.

    Can I sell a network-locked iPhone 18 Pro Max?

    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 18 Pro Max?

    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.
