The phrase indicates a mobile device that has been previously owned and used by another individual. It signifies that the item is not brand new, but rather has been in circulation. For example, a smartphone sold by a retailer offering “certified” units falls under this description, indicating that the device has been inspected and possibly refurbished before being offered for resale.
Understanding this concept is important for consumers as it relates directly to price, warranty, and the overall condition of the product. Choosing to purchase these devices can offer cost savings compared to acquiring a new model. Historically, the market for these electronics has grown substantially, driven by environmental concerns and the desire for affordable technology.
