phone calls over WiFi
What is WiFi calling?
A feature where your phone routes calls through WiFi instead of the cellular network. Useful when cell coverage is weak but WiFi is strong (hotels, home, etc.).
In context
WiFi calling uses your primary line (typically your home SIM). It does NOT use travel.to's data plan — travel.to is data-only, no voice. Your home carrier may or may not allow WiFi calling abroad, depending on their policy.
