For a brief information, this exact phone has been available in Brazil since August 2013 (you can look it up).
I can say that it is a very USEFUL phone. If all you want is to make phone calls, messaging (SMS/Whatsapp/SnapChat,etc.) and surf the internet a bit, it is a great value for the money.
Don't expect anything else though. The camera takes very small and blurry photos with huge amounts of noise, and the display is very innacurate and pixelated.
