In the aftermath of Typhoon Haiyan (Yolanda), the storm that razed several areas in the Visayas, Viber urges Filipino users to call their families and let them know how they’re holding up by opening a temporary service which allows them to call non-Viber numbers outside the Philippines for free.
To call someone using the service, users can select a contact in Viber and tap any of the numbers listed next to “Viber Out”.
