With the Voys app, you call through your smartphone's internet connection, via 4G/5G or WiFi. If that connection is not stable, we'll send you a notification to inform you. In this guide, you'll learn why you might experience connection problems even with the fastest internet.
The network
With the Voys app, you call through your smartphone's internet connection, via 4G/5G or WiFi. Calling via 4G/5G is strongly preferred for the best call quality, as WiFi is often simply less reliable.
Calling via WiFi
That might sound a bit strange, as many people are used to the idea that WiFi is fastest and most reliable. When it comes to watching videos, downloading photos, and similar activities, this is true. A phone call is different because it's a direct connection.
If your smartphone is connected to a WiFi network, the app automatically uses it. In most cases, this works fine, but sometimes it can cause issues with call quality. With a WiFi connection, calls are more likely to stutter, have delays, or drop completely. The app can't do anything about this. You can fix it by switching to 4G/5G.
This can also happen if you have a very fast and well-functioning WiFi network.
Turn off WiFi
We therefore recommend using the app with 4G/5G. If you notice your call quality is poor, turn off your WiFi connection. The call will automatically switch to 4G. You can do this during the call, on both Android and iOS phones.
