They always say that it is locked but "Device only full priced" is unlocked. Yes, it will work properly and get 4G LTE in Brazil.

I have friends in Rio who want me to buy an iPhone 6 for them. But I have no way to get it to them besides me flying there to deliver. If I send in the mail they will add high import taxes.
Yeah, If you send to Brazil it´s going to be probably the same price they are going to sell here. Not worth it, I think. And maybe even my sister is going to have problems carring two iPhones back to Brazil.
And thanks for the response. I was really worried about it just have a pretty paper weight. XD
