How to read the results

  • Carrier lock: “Unlocked” means you can insert other SIMs; “Locked” shows the current network.
  • Blacklist: lost/stolen devices are blocked on many networks; resale value drops sharply.
  • GSX data: “Sold By”, “Replacement/Case/Repairs” and warranty dates help detect refurbished or replaced units.
  • iCloud status: “CLEAN” can be activated; “LOST”/“ON” will fail activation unless the owner disables FMI.

Examples of typical results

A device showing Unlocked + iCloud CLEAN usually activates and sells faster. A phone with Locked + Sold By: US AT&T may require a carrier-specific unlock. If GSX lists Replacement or multiple Repairs, expect refurbished parts; price accordingly. iCloud LOST/ON cannot be used without the owner’s credentials.

Tips & common mistakes

  • Don’t confuse IMEI (15 digits) with SN; double-check before ordering.
  • Use the exact model’s IMEI; dual-SIM variants can differ in policy.
  • After unlocking, reboot with Wi-Fi and insert a non-original SIM; if needed, restore via iTunes (backup first).
  • For trade-ins, attach GSX/iCloud proof — it increases buyer trust and reduces disputes.
