Buying and selling used phones in Thailand: how to check one, and how to price it
Phones are the most traded secondhand item in Thailand, and the category with the most scams. The good news is that almost every problem can be found in five minutes if you know what to look at. This page covers the inspection steps and how to set a price that is fair to both sides.

Check before you pay (five minutes)
- Account locks: an iPhone must be signed out of iCloud with Find My off, in front of you. An Android must have the Google account removed. If the seller says "I'll unlock it later", walk away.
- IMEI: dial *#06# and compare the number with the box and the settings menu. A mismatch means a replaced board or a problem device.
- Battery health: iPhone shows it in Settings; on Android check charge cycles with a diagnostics app. Below 80%, deduct the cost of a new battery.
- Screen: display a full white image and a full black image — dead pixels, burn-in and water marks show up most clearly this way.
- Every port and camera: charge it for real, plug in headphones, shoot front and rear, zoom, record audio, and make one phone call.
Local-warranty, imported and repaired units
The Thai market mixes phones bought from local authorised sellers, grey imports, and units repaired with replacement parts. Prices differ a lot, and the listing should say which one it is.
A third-party screen or battery replacement is not wrong — but it must be disclosed. Buyers told up front usually accept it; buyers who find out later ask for a refund and leave a bad review.
If factory warranty remains, attach a photo of the receipt or the expiry screen. This genuinely raises the selling price.
Pricing so it sells within a week
Start from today's new price for the same model, then deduct for age, screen and body condition, battery health and completeness. The original box and cable add little value but speed up the decision.
Look at prices of the same model that have already sold near you, not the ones still sitting in the market. A listing that has been up a long time is a listing priced too high.
To sell quickly, price 3-5% below comparable listings in similar condition, and explain the price in the description: battery 86%, original screen, never repaired.
Meeting safely
Meet inside a mall or in front of a convenience store with cameras, somewhere with decent Wi-Fi or mobile data — you will need to sign accounts in and out and test updates.
Pay only after the checks are done, and never transfer a deposit to "reserve" a phone for someone you have not met. That is the single most common scam in this category.
