I'm going to Jamaica next week on my honeymoon. I have AT&T. I plan to bring my phone (3g), but I don't really plan to use it unless it's an emergency. In fact, I guess I don't even know if it will have service at all. I'm just assuming that it will and that I'll be roaming or whatever. I also assume that I would be paying an arm and a leg per minute, so that's why I'm not going to use it. What I'm really curious about is the data. I won't be purposely accessing data services, but what happens if it tries to check my email or I accidentally launch safari, etc. Does anyone know how the charges would work or how I could just have data turned off essentially to avoid any charges? I know I could leave the phone on airplane mode the entire time, but what if I decide to exit airplane mode to make a call or whatever, and it accesses data while out of airplane mode?
