A:AnswerPreowned have been sold and returned but need no repairs. Refurbished are phones that have some blemish and or malfunctions that required some repair to bring them back to functional and salable phones.
A:AnswerThese phones are not certified to work, they are only checked to be functional at the time they are acquired. There is no repercussion if the phone you get stops working a month after you buy it. I know from experience.
A:AnswerNope. You don’t know what you are getting as it’s not certified. You have 7 days to return it and after that you are screwed if anything goes wrong.
