Thank you VVHT for the help.
If I am understanding what I read, since I do have an iPhone 6, I should simply be able to purchase a SIM card from digacel as they do support both CDMA and GSM. I will reread tomorrow to make sure I got it right and didn't miss anything.
Ultimately I'd really love to just unplug completely and leave it home...but fortunately not possible as work will follow me wherever I try to hide....retirement sounds better everyday...getting closer lol
