After reading previous posts, still confused. I have iPhone 6, traveling in France, Germany, Czech Republic and Austria. To be able to send/receive text when out and about -- CELLULAR DATA on or off? DATA ROAMING on or off? I have yet to see an option called INTERNATIONAL ROAMING on any screen yet I've seen reference to it in instructions.
Regarding the WiFi hotspots -- over past 3 days in Paris, we have yet to be able to find and of the suggested WiFi connections identified in the AT&T Passport app. However we can connect to the hotel WiFi, does the latter give us the same service we would get if we ever find a connection described in the app?
TIA
