Phone cards are a great option. they can be tricky to use at times but 95% of the time they are great. Small problem, no one can call you on it when you are ar the beach.
Discount cell is a great company that gives good service and they are reasonable. the delivery girl is pretty and very prompt.
Aruba Fast Phones is a company I started and love the hell out of it. We do our best and hope to do business with you. My ex wife delivers while I sit at home and play with my 9 yr old son Junior. At 67 I am allowed right?
All options are good and no-one is here to do anything but make sure you have a wonderful vacation. And that includes all of us.
