What should I do if there is a place where I plan to use the service but there is a place where I am out of cell phone signal and Wi-Fi coverage?

If you temporarily go out of range, the connection will be disconnected, but it will automatically reconnect when you return to the radio range. However, it may not automatically reconnect to 2.4GHz WiFi. We have confirmed that 5GHz WiFi will automatically reconnect to WiFi, so if you want to automatically connect to WiFi while using a voice app, please prepare a 5GHz WiFi.
