A:AnswerYes, it will work in Brazil. This is a unlocked phone. I have used it in Africa (on a local network) without any issues. It comes with a sim. That got me worried but I guess it’s just marketing. Remove the sim and insert your Brazil sim, and you’re good to go.
A:AnswerNo, I tried the same thing with the one I bought for my daughter for my Metro PCS account. I switched the SIM cards and it did not work so I took it to the Metro store and they did it for me for $16 and some change.
