A:AnswerWhen you purchase a used cell phone just be certain it is unlocked and you will be fine with your new provider. Go to the cell phone store with your new phone and ask to have it activated with a new sim card and you'll be set to go!
A:AnswerYes, but you'd have to take it to the store. At first the metro rep told me it wasn't unlocked because once I put my sim it showed "no service", but then after she tried different things, she got it. It does work with metro.
A:AnswerThe iPhone 6s is a bit outdated now but will still do just fine in today's age, as of shipping to Morocco not sure unless there is a BestBuy somewhere in that country.
A:AnswerYes it should because it is an AT&T phone. GSM phones that worked for AT&T and T-Mobile lines will work in South America. Sprint or Verizon (cdma) won't.
