Match the listing to the device
The brand, model, storage, color and carrier status in the listing should match the phone in settings and the IMEI lookup result.

Check IMEI Before Buying a Used Phone
Used phones can be great value, but identity comes first. Check the IMEI, compare the model, test the basics and keep proof before you pay.

Test network behavior
Insert a SIM or test eSIM activation where possible. A device can look correct but still be locked, financed or unsupported by your carrier.
Keep evidence
Save the listing, receipt, seller messages and IMEI report. Those records help if a dispute or warranty question appears later.
Common questions
Should I buy if the seller refuses to share IMEI?
For expensive phones, refusal is a warning sign. Ask for a photo from settings rather than a typed number.
Is model identity enough?
No. It is the first step. You should also check physical condition, account locks, carrier behavior and payment history.
