Question: so is it unlocked? can I use it in a country outside the US?
Document: Received the product just as described, easily unlocked, works fine with my old cell phone chip.I use it in Brazil with no problem.
I purchased this Phone kind of used one, But surprised to seee that its almost New, everything so perfect that i am buying another one from the same seller. I love it.
The back to it is all scratched up, there's this grey bar at the top of the screen that won't go away and hides the time, there is no sim card, and no headphones will work in it, meaning the piece in it is all jacked up.
Answer: no
