Name * Password * Email T-Mobile's Wi-Fi Calling can be used outside the U.S. to call U.S. numbers for free, but charges apply for calls to non-U.S. numbers, with rates varying by your plan and destination. To avoid potential cellular charges, enable Airplane Mode on your device and then turn on Wi-Fi. For extended international travel or higher data needs, consider adding an International Pass. 즉, Wifi zone 안에 있을때 Wifi-call을 켜두신 상태에서 해외에서 미국 전화번호로 전화 하는것은 무료, Non U.S number로 전화하시면 charge가 됩니다.
