Buying a used phone can save money, but knowing where it comes from is key to avoiding problems. Here's a guide to common sources and tips to stay safe:

 

1. Official Refurbished Phones

What they are: These are old phones (returned or display models) fixed up by the brand.
Example: Apple's Certified Refurbished or Samsung Renewed.

Why they're good:

Come with a 1-year official warranty.

Look and feel almost new, with fresh accessories.

 

2. Trade-In Programs

How they work: You trade your old phone for a discount on a new one, and the old phone is resold.

Pros: Cheaper than official refurbished phones, sometimes with a short warranty.

Cons: May not be fully repaired, just basic checks done.

 

3. Personal Sellers (Online Marketplaces)

Where to find them: Apps like Xianyu, Zhuanzhuan, or Facebook Marketplace.

Risks:

Sellers might hide issues like water damage or past repairs.

Could be stolen (always ask for the original receipt).

What to do:

Ask for the box and invoice.

Use tools like Aisi Assistant to check repair history.

 

4. Professional Secondhand Shops

Places like: Online stores like Shanhui Shou or  Zhaoliangji, or offline phone markets.

Good points: Provide inspection reports and 7-day returns.

Watch out for: Some might sell frankenphones (put together from different parts) or phones with fake codes. Cheap ones may have non-original batteries/screens.

 

5. Corporate/Lease Returns

From companies: When offices upgrade their phones, the old ones are sold.
Pros: Uniform condition, clear usage history.
Cons: Batteries might be worn out from heavy use; make sure they're not locked to a company system.

From lease services: Phones returned after the rental period, often with visible wear and tear.

 

How to Stay Safe When Buying

 

Step 1: Check the IMEI/Serial Number

Make sure it's not lost or stolen. Use Apple's website or imei.info for Android.

 

Step 2: Test Everything

Screen: Drag an icon around to check touch sensitivity.

Camera: Take photos and test zooming.

Calls: Check the microphone and speaker quality.

 

Step 3: Inspect Inside (for high-risk phones)

Look for signs of water damage or repairs. Non-original parts (like batteries) are a red flag.

Useful Tips

Check codes: Make sure the IMEI on the phone, box, and bill match.

Avoid scams: If the price is too good, it's probably a trick. Stick to official channels when possible.
