The application offers users the ability to make free phone calls to anyone around the globe, regardless of whether the recipient has the Duo Phone Call App installed.

This flexibility caters to a wide range of user preferences and enhances the overall user experience.
Additionally, the application supports international calls to over 230 countries at significantly reduced rates, claiming savings of up to 90% compared to traditional calling rates.
