We have the iPhone - does anyone know if the phone, including e-mail and apps like facebook will work in the USVI? We'll be traveling to St. John and I want to know if I'll be able to keep in touch with work and family back home. If it does work, are there additional charges?
The US Virgin Islands is in the domestic coverage area and there should not be any extra charges for voice or data.
I read of one person actually getting international charges because they connected to a non-US tower, British Virgin Islands or something like that. To be safe on the towers your connecting to (for those that are paranoid like I am), you can ask ATT to add the "4EON" feature code to your line(s). This way if you connect to a non-US tower you will see "Off-Network" instead of the normal "AT&T" in the top left corner so you would know not to place a call.
Also leave Data Roaming turned off in the settings so you can't use any data from non-ATT towers.
