What I would suggest is go to the local phone shop of the island you are on and buy the cheapest quad-band cell phone
they have. It should be under $100. This phone will last you for a long time and work anyplace in the world. Then, get a prepaid sim card. Put maybe $50 on it. When you move to another island, get their local sim card. If you go to Europe
, get one there.
In St. Maarten, TelCell is about $.30/min to call the USA. If you talk for a hundred minutes, it's saved you $70 over a US based cell phone.
BTW, if you do a Cruisers Forum Google
Search, there are a lot of threads on cell phones in the caribbean
. Under the search tab at the top of the screen
, hit the down arrow and choose the second search box.
