There will be four of us travelling in Paris next week, all with I-phones. We only plan on using them to coordinate meeting up, if someone gets lost or delayed, etc. Not looking to do much voice, minimal texting. From what I can find on the AT&T site, text charge is $.50 to send and $.20 to receive a text abroad, which I am fine with. Again, we-re planning on minimal usage. My questions is, can you set up your phone to only allow calls/texts from certain people, so I can communicate with my fellow travellers but not get calls and texts all weeks from the US?
