You can text "Global to 4004' with Verizon to open up global calling, and it has worked for us in the past on St. Maarten. Even worked on St. Barth's. I think every time you use it once it's on your phone you'll be charged something like $5 or $10, but beware that if you receive your e-mails on your Verizon plan that also triggers a payment for that day (just not incoming and outgoing phone calls). You might want to Google this with Verizon to see what the plan is presently.
