2) Smartphones: IMEI check and key points
Check IMEI number
The IMEI (International Mobile Equipment Identity) number is unique to each phone. Type *#06# on the phone keypad to display it.

- A blacklisted phone cannot be used on Swiss networks
- Compare the IMEI number displayed on the screen with the one written on the box
Essential tests for a smartphone

- Battery: check the health status in the settings (iOS) or with an app (Android)
- Cameras: test photo and video, autofocus, flash
- Connectivity: Wi-Fi, Bluetooth, GPS, mobile network
- Sound: speakers, microphone, headphones
- Buttons and sensors: volume, power, fingerprint reader, Face ID
3) Laptops: battery and performance
Battery Status
The battery is the element that ages the fastest. Request a battery health report:
- macOS: Option + click on the battery icon, or use coconutBattery
- Windows: Order
powercfg /batteryreportin the terminal - Linux: Use
upower -i /org/freedesktop/UPower/devices/battery_BAT0
A healthy battery should have more than 80% of its original capacity.
Performance and general condition
- Test USB, HDMI, audio, SD card reader ports
- Check the keyboard (all keys work)

In Switzerland, the legal guarantee is 2 years for new products purchased from a retailer. For the occasion between individuals, there is generally no legal guarantee.
- Request the original purchase invoice if available

If there is no guarantee, negotiate the price accordingly. Check out our pricing strategy guide to know how to correctly evaluate a used device.

- Seller who refuses to show the device turned on or to do tests
- No original box, accessories or documents
- IMEI that does not match the official information
- “Imported” product without local warranty

- Meet in a safe, public place (station, café, police station)
6) Secure payment and remittance
For second-hand electronics, always choose hand delivery with complete testing of the device.
