Frequently asked questions

Every device sold by Cell Devices has been fully tested, graded and checked against a 25-point inspection process. It's been used before but works perfectly — and comes at a fraction of the new price. Our technicians personally inspect every device before it leaves.

All grades come with next working day delivery, and accessories are half price when bought with a phone — a fitted tempered glass screen protector is £10 instead of £19.99. See the full breakdown on the About page.

Yes — every device is fully unlocked to all networks before it leaves. Just pop your SIM in and go.

Your phone and your order confirmation as proof of warranty. Accessories are half price with a phone — add a fitted tempered glass screen protector for £10 (normally £19.99). Chargers aren't included — all phones use USB-C or Lightning depending on the model.

No — this is normal on refurbished iPhones and can appear even after a repair using genuine Apple parts on models older than iPhone 14. It's an Apple hardware restriction and does not affect performance, features, or your warranty in any way. Your device is fully tested and covered.

3–5 working days door to door. Most repairs are completed within 1–2 working days of arriving. We message you when it arrives and again with a tracking number when it's posted back. See the repairs page for the full process.

For most repairs, no — you pay once the quote is confirmed. For software and diagnostics, a £40 fee is paid upfront via payment link before posting. If the repair goes ahead, the £40 comes off the total. If it can't be fixed, the £40 stands but return postage is covered.

It depends on the model and parts used:

• iPhone 12 and newer with genuine Apple parts — calibrated after fitting. No warnings in Settings.
• iPhone X, XR, XS and 11 series, any parts — will show 'Unknown Part' regardless. An Apple hardware restriction that can't be removed. Doesn't affect performance.
• iPhone 12 and newer with third-party parts — 'Unknown Part' will appear. Only genuine parts can remove this.
• All camera replacements — show 'Used' in Settings on all models. Software flag, no effect on function.

We're always upfront about this before anything is agreed.

Often yes. We regularly fix phones other shops have handed back — including water damage, dead batteries and logic board issues. The £40 diagnostic fee applies first, coming off the total if it's fixable. We advise honestly before any work is done.

Yes — genuine Apple OEM parts are available for screen and battery repairs. On iPhone 12 and newer, genuine parts are calibrated after fitting so no warnings appear in Settings and True Tone is preserved. On iPhone X–11 the note appears with any part, genuine included.

12 months on parts and labour for repairs. The one exception is the budget LCD screen tier — sold as a temporary/data-transfer option — which carries 3 months. If the same fault returns within the warranty period and it's not accidental damage — we fix it at no charge.

Always recommended. We take every care, but backing up via iCloud or a computer protects you regardless. Remove your SIM before posting too — it's not needed for the repair.

We'll let you know before doing any work. For diagnostics the £40 stands, but no further charge. Your device is returned to you tracked — at no cost to you.

Yes — any condition. Cracked screens, won't turn on, water damage, multiple faults. our technicians review every broken device personally and typically pays more than automated buyers like CEX, Music Magpie and Mazuma — especially for damaged devices that automated systems reject outright.

Bank transfer sent the same day your device arrives and is inspected. Usually in your account within hours of arrival.

When you put your trade-in value toward one of our refurbished phones, you typically get 25–35% more than a straight cash sale. Because we refurbish and resell your device, we can pass that value back as upgrade credit. If you decide not to upgrade, you get the cash offer instead — no pressure.

It works both ways. If the device is worse than described, we'll always discuss it openly before anything changes — and you can have it returned for free. If it's in better condition than expected (say it powers on when listed as dead), we message you and offer more. We could pay the original offer. We don't.

Ideally yes — locked devices are harder to resell and will affect the offer. We'll factor this in and discuss it with you. It doesn't mean we won't buy it — just that the offer will be lower if the lock can't be removed. We can often guide you through removing it in just a few minutes.

It gives a reliable estimate based on current market data and your device's condition and faults. The final offer is confirmed personally by our team after a quick conversation on WhatsApp. If the device matches what was described, the estimate stands.

No problem — if you decline the final offer, we return your device free of charge. No hassle, no questions asked.
