Good point. If I’m calling an intl number, the normal charges would apply. I see what you were asking. The Wi-Fi calling only lets me use my phone normally as I would on LTE in the states. If I called Europe from Memphis, I would get charged for it.
But I can be in a hotel overseas and use my phone normally.

I also occasionally use the AT&T Passport portion of my plan. Which allows me to use my phone on LTE/4G overseas for an additional $10/24-hr period. Turn on the cell signal, walk around Milan/Paris etc. I only do that if I’m going exploring and would like to use the maps, call the wife, etc. All data/calls for the Passport are just the normal monthly accumulation for my bill...the only extra charge is the $10 for that 24 hr period.
