Nigeria runs the largest used-phone market in Sub-Saharan Africa. Computer Village in Lagos alone moves tens of thousands of "UK used" iPhones, Samsungs, Tecno and Infinix devices every week, alongside Alaba International, Tradefair, the GSM markets in Aba, Onitsha and Kano, and a fast-growing online layer on Jiji, Jumia and Instagram.

It is also why scams are common. With NCC-DMS (Device Management System) live since October 2025, the rules shifted in the buyer's favour — but only if you check the IMEI before you pay. This is the practical safety checklist you can run in five minutes.

Why the Used-Phone Market Is Riskier Than It Looks

A used iPhone 13 advertised for ₦310,000 in Computer Village can be:

  • A genuine UK-used phone with a clean IMEI and no carrier lock — what you want.
  • A stolen device whose IMEI is on the NCC-DMS register and will go dead within days.
  • An iCloud or MDM-locked device that displays the activation screen the moment you reset it.
  • A smuggled phone with no SON type approval, which will fail NCC-DMS verification.
  • A counterfeit running a skinned Android made to look like iOS.

Physical inspection spots two of those five. The other three need an IMEI check. That is the difference between paying ₦310,000 for a working phone and paying ₦310,000 for a brick.

The Five Checks Every Buyer Should Run

Run these in order. If any single check fails, walk away — there is always another deal.

Check 1 — Get the IMEI in front of the seller. Ask the seller to dial *#06# on the phone. Compare the 15-digit number on screen with the IMEI printed on the back of the box and (for iPhones) etched in the SIM tray. All three should match exactly. A mismatch usually means the back panel has been swapped or the phone has been re-flashed with a fake IMEI.

Check 2 — Run an instant IMEI lookup. Use our <a href="/ng/">Free IMEI Check</a> directly on your phone in front of the seller. Paste the IMEI and read the report aloud. You are looking for: device model matches what the seller said, registration status is Clean, and there is no Blacklist or Reported-Stolen flag.

Check 3 — Confirm with the NCC-DMS portal. Open ncc.gov.ng on your phone and run the same IMEI through the official NCC-DMS verification page. A two-source match (free lookup + NCC) is what you want before paying.

Check 4 — Test with your own SIM. Eject the seller's SIM and put yours in. Make a call. Send an SMS. Open a data-heavy page (a YouTube short is enough). If the phone shows "no service" on your live SIM in good coverage, the IMEI is almost certainly already blocked.

Check 5 — For iPhones, force the Apple ID check. Ask the seller to sign out of iCloud in Settings → Apple ID → Sign Out. They must enter the Apple ID password. Then go to Settings → General → Transfer or Reset iPhone → Erase All Content and Settings. If the phone reboots into the Activation Lock screen, walk away — even if the IMEI is clean, the device is useless without the original Apple ID.

Red Flags You Can Spot Without a Phone

Some warning signs do not need an IMEI lookup. Treat any of these as reasons to leave.

  • The seller refuses to let you dial *#06# or to fit your SIM.
  • The price is much lower than market rate. A "London used" iPhone 14 at ₦220,000 in 2026 is suspicious.
  • The IMEI label on the back has been scratched off.
  • No box, no charger, no proof of purchase — and the seller cannot name a verifiable previous owner.
  • The seller pushes payment through an unfamiliar POS or third-party agent.
  • The deal is happening late at night or in a back-alley shop.
  • The phone was wiped immediately before showing it to you.

A working phone with a verifiable history passes all of these. Stolen or smuggled phones almost always fail one or two.

The One-Page Pre-Purchase Checklist

Save this list to your phone. Tick each item before you transfer the money.

  • IMEI on screen (*#06#) matches box and SIM tray exactly.
  • Free IMEI lookup returns Clean status and correct model.
  • NCC-DMS portal returns Clean status.
  • Your own SIM makes a call, sends SMS, and loads data.
  • For iPhone: signed out of iCloud, factory reset completes to setup screen with no Activation Lock.
  • For Android: signed out of Google account, factory reset completes, no FRP lock.
  • Seller provides a written receipt with full name, phone number, and IMEI.
  • You have the seller's location and a way to contact them after the sale.
  • Payment is by bank transfer with a confirmed reference.
  • Original box, charger and accessories handed over (or a clear discount agreed for missing items).

You can run all ten items in under fifteen minutes. That fifteen minutes is the difference between a clean used phone and a paid-for brick.

After You Buy: Register the IMEI in Your Name

Once the money has moved, your job is not finished. Transfer the IMEI to your NIN on NCC-DMS within seven days. Until then the seller's NIN is still on the IMEI — and if they report the phone "stolen" by mistake, your phone gets blocked.

Visit ncc.gov.ng, open the device transfer flow, enter the IMEI and the seller's registration reference (it should be on the receipt), and add your NIN. A confirmation SMS arrives within 24–72 hours. Save it — that is your proof of ownership.

If the seller has no registration reference, self-register the IMEI fresh with the receipt, a photo of the box, and ideally a video of the handover.

Frequently Asked Questions

Is it still safe to buy a used phone in Computer Village? Yes, if you run the IMEI safety checklist. NCC-DMS makes the check much more reliable than before October 2025 because a flagged IMEI will not work on any Nigerian network.

How long should an IMEI check take? Less than five minutes. The free lookup and the NCC-DMS portal both return results within seconds. If the seller is rushing you, that is a flag.

Can a "London used" phone fail NCC-DMS? Yes. A genuine UK-imported phone needs to be NCC type-approved and registered after entry. Phones brought in undeclared may show as Not Registered, which means the device cannot legally activate on a Nigerian network until you complete the registration.

Should I trust a seller's screenshot of an IMEI check? No. Always run the check yourself from your own phone. Screenshots are easy to fake or stale — they may show a status from before the IMEI was reported stolen.

Is there a downloadable checklist I can take to the market? We are preparing a one-page PDF version of this checklist that you can save offline. In the meantime, screenshot the bullet list in this article and bring it on your phone.
