I have done pretty much the same thing as Cacapasa, except I use my regular phone. Once the plane leaves the US, I switch SIM cards in my US phone. This gives me the advantage of retaining all my US contacts in the phone I use on island. I used to go to Tech Hub to get it set up, but now that I'm more familiar with the setup, I just go to The Mailbox, which is closer to where I stay, to pay for data. I used to pay $35 for thirty days. This time it was $18 for thirty days. I will add another week when my thirty days are up. I really like having wifi at all times without having to enter passwords of various venues I visit.
