WhatsApp voice calling a threat to MNOs
The recent introduction of the voice calling feature on WhatsApp will change the focus of mobile network operators (MNOs). As an over-the-top (OTT) service provider, WhatsApp has the financial, technical and social clout of Facebook supporting it, as well as a significant user base. MNOs have anticipated this step change in the telecommunications industry whereby voice revenues are challenged and ultimately replaced by data-based services.
