A:AnswerHello! We appreciate your interest in our products. This is a USA unlocked device and its warranty is only good in the country it was originally designed for use in. We hope this answers your question and helps you with your purchase decision. ^Rod
A:AnswerThe same thing happened to me. I had Verizon previously and went to check with them after buying the unlocked Samsung 8. They told me I don't get their Verizon voicemail. I have to pay attention and push 1 for voicemail and use password.
A:AnswerOpen box means it was sold and returned. It may be missing things, chargers etc. It will be cheaper but sometimes not by much if the product goes on sale.
A:AnswerMy understanding the unlocked S8 can work internationally on any GSM network. Would not specifically need SM-950F for use anywhere in the world on GSM networks, is my understanding. Hope this helps.
