Bringing my phone to the island, (YES I know there are people who provide rental phones but I prefer mine). So here is my question(s): I'm on the french side and want to dial a number on that side say 590690536144, do i just put a "1" in front of it, or do i need the international number/prefix? Same scenario but now im dialing a dutch side number--721-544-5456, what numbers do i have to put before that number?? Lastly we meet someone on the island with their US phone...say 504 267-8989. What prefix do I need to call them? THANK you all in advance!!
