Safe buying steps
- - Do not pay before inspection or a trusted handoff.
- - If the seller is far away, ask someone near that area to inspect the phone first.
- - Confirm IMEI, SIM/network lock, battery health, screen, cameras, charging, and biometrics before paying.
- - Meet in a safe public place and keep the listing/chat evidence until the deal is settled.
