A:AnswerIf the phone says refurbished then it is, otherwise it is not. It usually comes in packaging that also states refurbished. So I don't think you can leave without knowing. Also best buy usually has the cheapest prices.
A:AnswerThe same thing happened to me. The people in the store are not very knowledgeable about this. Definitely a Samsung S8 unlock does not work with Boost Mobile. The only way to buy the S8 for Boost is on the BestBuy website.
A:AnswerBest Buy sells the S8 factory unlocked if you prefer that. You can also buy one for your carrier and unlock it yourself. However, if you try to use an unlocked phone with another carrier make sure that the carrier supports the signal type. Not all unlocked phones will work on every carrier.
A:AnswerUnfortunately no. You would still have to pay for it to be unlocked or you can unlock it on your own for free if you have the software but will still have to pay for a simunlock or another sim.
A:AnswerYou can unlock any phone but it may be a bit problematic in some cases with some carriers but if your going to use it on a CDMA carrier you will be fine im sure of.
