Incurring Text Charges While Out of the Country
My wife and I were in Mexico last month with our iPhones set to "Cellular Data" OFF, "Roaming" OFF, and "Wi-Fi Calling" ON. My wife has the international plan were if you make at least one international call (which they all will be since we were out of the country) you get charged $10 for the day. We assumed all our texts were going through Wi-Fi as the resort had Wi-Fi just about everywhere. From what I understand AT&T's system would only pick up the message if it was on cellular. But how can that be? If we were set to Cellular OFF how did that happen? Could some other app switch the "Cellular Data" to ON? Thanks in advance.
