Not to doubt the front page article, but it says the source is the sprint press release... And yet the press release is right here:
http://newsroom.sprint.com/news-releases/samsung-galaxy-note-4.htm?previousArticle=11573&nextArticle=11572&gotoArt=%2Fnews-releases%2Fsamsung-galaxy-note-4.htm
It simply says Wi-Fi calling, and in no way does the language indicate this is restricted to out of country only. In fact Sprint has never done this, and based strictly on the press release, they could get in a lot of hot water for false advertising if they did it this time. The word "international" is simply not there.
