Honest market read

What Decide thinks before you even meet the seller

This is a high-risk used buy in Nigeria. Only proceed if you can inspect the device properly, verify the variant, and absorb repair friction if anything goes wrong.

Seller questions

Ask if the device is brand new, activated, UK used, refurbished, or converted.

Ask which parts have ever been changed: battery, screen, back glass, charging port, or board.

Ask the seller to reset it in front of you and stay with you through activation before you pay.

Red flags

Slow down if any of these show up

Apple Intelligence requires iOS 18.1+ — confirm the phone activates cleanly. Camera Control button is a great authenticity check — fakes won't have it. All iPhone 16 units support physical SIM globally. Verify IMEI on checkcoverage.apple.com before buying.
Ask directly whether the unit is sealed, activated, refurbished, or previously used abroad.
Weak local support means your real risk is not just authenticity - it is what happens if the screen, battery, or board needs work later.

Inspection flow

Run the actual checks before money changes hands

This section adapts the checklist to the phone's OS and brand, so the warnings are much more specific than a generic used-phone article.

Keep the used decision in context

A used buy should still flow through the rest of Decide before you hand over money. Timing, support, and nearby alternatives matter just as much as seller trust.
