Any of the Galaxy phones from the S6 up including the note 5 work. The other person MUST have a phone that supports video calling. In your contact list you will see a green video camera to the right of the phone number if that person has a phone that supports video calling.
My understanding is it only works on the same carrier for now. On Verizon I think only the Samsung phones support it. I was told that support for other phones is coming this year, like for iphones.
