Make free calls over the Internet

Duo Voice is an app that lets you make free calls over the Internet in exchange for viewing ads, performing daily tasks or inviting friends to use the app. There are loads of things you can do to receive credits. And, if you can't get credits through the ads, they can be bought with real money at a low cost.

To use Duo Voice, you must have a real phone number. This number serves as your identifier in the calls you make, and you can make them to more than 200 countries around the world. After registering with your number, you'll receive 500 free credits to start making calls.

Calls are made over the Internet using VoIP, so you can make them using your Wi-Fi network or using data over 3G, 4G or 5G networks. Calls, when made over the Internet, have a higher quality than those using traditional telephone networks. However, the latency in the call may be a little higher, and if you make a call to a country that is far away from your own, the audio may have a little lag.

If you want to make Internet calls at affordable prices, then download the Duo Voice APK.
