The products we offer do not support “WiFi Calling” unfortunately.

Your device may give you the option to enable a “WiFi Calling” feature but even if this feature is enabled, the call will still go through as a normal call (as long as you are in an area in Japan where network coverage is available) and your call will still be chargeable at the standard per minute rate.
