I will be taking my iPhone 6 (ATT) to Italy and France next month for 15 days and am debating adding the $30 Passport or pay-as-you-go .50/text option. From what I read it seems like when we are in wi-fi it texts would be free to our family with iPhones in the US as iMessages but we when we don't have wi-fi then there is the per text fee.
If I want to send a text to an Italian tour guide do I enter it is as +39 399 123 4567? And texting someone in the US is + 1 (area code) 1234567? Does the same dialing directions hold true for voice calling?
Thank you!!
