Ok, here's my 2 cents. We dropped verizon many,many years ago. I went with Consumer Cellular which uses AT&T transmission/wireless. I also bought a Samsung S4 Quad phone for international travel. Consumer has no long term contract, just month to month plans and allows you to select as much or as little as you want , data/voice/text and they give alerts when you may becoming anywhere near your plan. You can bring any GSM phone and set it up with them. I will say , from what others have told me, you do have to be careful while on the north side of St. John as you may get connected via a tower in the BVI's and incur international charges. We've had wonderful connection with all aspects of phone and service. This may or may not help. As I said, just my 2 cents. Cheers
