I have Simple Choice Plan with Stateside International Services with unlimited calling to 70+ countries and 30+ countries mobile. I have been using this service for more than 6 months and never been charged for my international calls to India. Recently (11/09) onward, I have been charged for my calls to India. I called to Support center and I was being told that the International calls I make over WiFi are charged as per international calling rates. What is the use of WiFi Calling then, if I cannot make international calls as per my plan? Why T-Mobile is not able to differentiate between WiFi calls from US and those from Outside US?

Just wanted to give an official update that we have identified this as a known issue with iOS 8 and it should be squared away by March. If you're connected to WiFi for an extended period, the iPhone doesn't know where you're at (domestic or international). We want to be transparent as possible. If you're impacted, you shouldn't be financially impacted by this bug. Until resolved, we'll continue crediting the $0.20 per minute you were charged while connected to WiFi.
