Limited Warranty: Refurbished phones typically come with a limited warranty, which means that you will not have any protection should the phone malfunction or be damaged.
Unknown History: When you buy a refurbished phone, you do not know who owned it before you or if the phone was properly maintained.
No Manufacturer Support: Many manufacturers do not provide the same level of customer service for refurbished phones as they do for new phones.
Limited Accessories: Refurbished phones may not come with all of the original accessories that new phones come with, such as a charger or earbuds.
