WhatsApp hits 800 million users; voice calls coming to Windows Phone version
Besides allowing users to send messages to each other, WhatsApp has now added voice calling to the Android version of the app. It soon will offer the same feature to iOS users and Windows Phone users as well.
A leaked image showing phrases that will be translated for WhatsApp's Windows Phone users in other countries has surfaced. With such actions as "Dialing, Incoming Calls, Answer, Ignore and Message," it is pretty apparent that Windows Phone users won't miss out on the ability to make and take voice calls using WhatsApp. And that is sure to make users of the platform feel good.
