At the Mobile World Congress earlier this year, WhatsApp CEO Jan Koum announced that the popular instant messaging client would soon be adding voice services to its feature list. The assumption has been that the service would be similar to Skype or Facebook Messenger. Now it looks like the voice calling functionality is coming pretty soon.
The evidence comes from the people who work to translate WhatsApp into Hindi. Screenshots of the translation request show that WhatsApp has three new strings it needs translating: Hang up, Incoming call, and Outgoing call. Translating the UI elements is one of the last stages when it comes to adding features.
Koum had said that the feature would hit in the spring. Voice calling will be coming to Android and iOS to start with Windows Phone and BlackBerry getting the update afterwards.
