International data usage and charges
I’m getting ready for a cruise of the British isles so I’m researching iphone and iPad usage. Both devices are new and have the latest bells and whistles. I’ve read much here about ATT WiFi calling and hopefully I understand the use and cautions with calls and texts. My question centers mainly about data charges. I have a postpaid 6 gb plan with unlimited texts. If I post something on FaceBook that may or may not include pictures, will I need to have an ATT International plan of some sort or will I be able to use Att WiFi calling to connect and send (assuming I can connect on it) and it would count against my data plan? Sending pictures in a text is included in my plan if I read the forum answers correctly? Any cautions/advice on the use of the ship’s WiFi? And if I turn off WiFi Assist, Roaming and Cellular and turn on Airplane Mode am I secure in avoiding charges or is there something else I need to turn off as well? Thank you.
