Whether you are buying a new phone at Computer Village, a “UK used” iPhone from a vendor on Instagram, or a second-hand Android from a friend, a few simple checks can save you from a fake, a disguised refurbished device or a stolen phone. Do these checks before any money changes hands.
1. Check the IMEI number
Every phone has a unique 15-digit IMEI number.
- Dial *#06# on the phone. The IMEI appears on screen.
- Compare it with the IMEI printed on the box and, on many phones, in Settings → About phone. All three should match.
- Enter the IMEI on the manufacturer’s checker where available. For iPhones, use Apple’s Check Coverage page, which shows the exact model and warranty status.
If the numbers do not match, or the checker shows a different model, walk away.
2. Inspect the phone in person
- Look for uneven gaps around the screen, loose buttons or a camera bump that feels cheap.
- Check that the screen responds everywhere, including the edges.
- Test the cameras, speakers, microphone, charging port, fingerprint or face unlock, and Wi-Fi.
- Put in your own SIM card and make a call to confirm the phone connects to the network.
3. Check the software
- iPhone: go to Settings → General → About and check the model name and storage. Under Settings → Battery → Battery Health, a used phone below about 80% will need a new battery soon.
- Android: check Settings → About phone for the model and storage. Install a trusted device-info app from Google Play to confirm the processor and memory match what the seller claims. Fakes often claim much more storage than they really have.
- Make sure the phone can update its software from the official settings menu.
4. Make sure it is not locked or stolen
- On an iPhone, the seller must sign out of their Apple ID. If “Find My” is still on, the phone can be locked remotely and becomes useless to you.
- On Android, the seller should remove their Google account before a factory reset. Otherwise the phone may ask for their account after reset.
- Ask for the original receipt or proof of purchase for expensive second-hand phones.
- A price that is far below the market rate is a warning sign.
5. Pay safely
- Buy from authorised dealers or well-reviewed shops where possible, and ask about the warranty.
- For online sellers, meet in a public place and inspect the phone before paying. Avoid paying the full amount in advance to sellers you do not know.
- Get a written receipt showing the IMEI number.
