Our carrier T-mobile doesn't have coverage on St. John, so we will need another option. I have read about the Go Phones by ATT. Do those work on the island? Where should we get them--in the US or once we arrive on St. John? We would like one that worked prior to arrival since we are supposed to call the villa company (Viva) from the airport and also from the STT ferry dock. We would also like to have people at home able to contact us. What is the best alternative? Thanks! We have 13 days until we are THERE! Yahoo!
