If you have the same one I have, you can buy credit anywhere in Negril/JA & add it. Of course, you'll have to have wifi access somewhere to add the credit. There is a way to do it online but I did that w/ help when I had the USB modem. I have the black box one now & had to figure out how to add credit myself. Probably easier to do it at the store but eventually doing it yourself is probably a good idea. If I could figure it out, it should be a breeze for others. LOL
