Unlimited free calls on 15GB/30 Days International Data Pass and Wi-Fi Calling
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 with...
WiFi calling is thru data line, not voice line. So it should be totally free (this depends on your plan too, if you have unlimited calling within the U.S.)
I was traveling and working remotely around the globe for last 10 years (Taiwan, Japan, Singapore, Thailand, Maldives...etc) Never receive any charge on Wifi Calling. There is one time I was on the phone for over 4 hours!
But be aware that iPhone sometimes dropped out from Wifi Calling connection. There were couple times before I try to make the call, I noticed my U.S. number's signal didn't say 'T-mobile Wifi Calling' at the end. I had to turn off/on Wifi connection on the phone and wait till it registered the Wifi Calling.
How was your internet connectivity while in Japan? Were you able to receive local calls without the caller having to make an international call to your US number?
