Going to St. Martin in a couple of days with my Motorola Droid Global Black which I purchased specifically for overseas travel. When I was in St. Martin previously, I had to rent two cell phones since part of the island is French controlled and the other is Dutch controlled -- each operating separate telephone systems. Question: Can I use my phone there? How do I switch from the US system to their's. I have never done this before, but paid a nice sum for this phone. Please advise ASAP! Thank you.
