Summary: Yes and no. All I have to do was put a SIM card and on my way. The thing I don't like is the camera there's no font camera I cannot use video Skype I can hear the person unable to see them, but I need to go to Haiti and I already used it here in the US.
Summary: I bought two of these after trying two Motorolas that I returned. These Samsungs have performed well. They accepted my sim card with no problem. I was looking mostly at price. Problem is that there is practically no internal memory. I put a 32 gig card in one and a 16 in the other.
