Is Vonage Mobile using my Wi-Fi connection or my cellular carrier’s 3G/4G data network to place a call?
By default, Vonage Mobile will first attempt to place a call using your WiFi connection.
If you are not connected to a Wi-Fi network, Vonage Mobile will look to complete the call over your cellular carrier’s 3G/4G data network.*
*Carrier charges may apply over 3G and 4G networks if you are roaming or have a limited data plan.
