I'm going to be traveling to Puerto Rico soon and have been wondering if I will be fine using my iPhone there for voice and data without incurring any additional charges (I have the typical Nation FamilyTalk plan). What I found here and in the comment from at&t's site below, makes it look like I'll be ok: While using data on iPhone is unlimited within the U.S., Puerto Rico, and the U.S. Virgin Islands, international data roaming can get expensive quickly as international roaming rates apply. Voice and data usage, including data usage incurred from delivery of Visual Voicemail messages, will be charged at international rates. For a complete list of countries and rates visit att.com/wirelessinternational. AT&T offers these iPhone International traveling tips to help you keep control of data usage. On the contrary, anyone have any experience with traveling to PR and using their iPhone and getting hit with extra charges? I hope not, and I think I'm fine, but I just want to make sure. I already asked a rep at at&t but you never know with them Thanks and I appreciate it!
