When using NumberSync to make or receive calls to:
- The U.S., Puerto Rico, or the U.S. Virgin Islands – We won't deduct from your smartphone plan minutes, even if you're traveling abroad and call a U.S. number.
- An international number – We charge international long-distance rates based on your smartphone plan or international option. It doesn’t matter where the call originates.
Heads up: Data charges apply if you use a tablet that isn’t connected to Wi-Fi to make or receive NumberSync calls. This includes standard U.S. data rates and international data rates when traveling abroad.
