I was told by a retail sales rep at a T-Mobile retail store today that unlimited free calls to/from/within Simple Global countries on International Data Pass only works on Wi-Fi Calling and that without Wi-Fi calling the charges for each call is $.25/minute (Magenta plan). This does not seem right as this would mean locals calls made within a Simple Global country would result in an international call originating from the U.S. Instead of being a free call, I believe, this would result in a $3.00/minute call.
Do we really need to turn on Wi-Fi Calling while on International Data Pass?
I am planning a trip to Japan and don’t want any surprise billing when I return from the trip. Would appreciate any comment from people that have used this service.
