What is the difference between used, refurbished, and brand new phones?

Used phones are pre-owned devices sold as-is, usually with minimal testing or repairs. Refurbished phones are professionally tested, repaired if needed, cleaned, and restored to full working condition, often with a warranty. Brand new phones are factory-sealed, never used, and include a full manufacturer warranty.

Yes. All refurbished phones go through a thorough 30+ point inspection covering battery health, screen responsiveness, cameras, charging ports, and more.
