Not yet .. the app is out but calling still needs to be activated , from what I have read they will activate certain areas over the next couple of weeks.
Hope SA is on the list sooner than later
Doesn't the call-trick work, as it did on Android? i.e. someone with voice calling enabled, calls someone without voice calling, which should then activate voice calling when that person answers...
It's working for me now, on my iPhone 6.
What is your Appstore account country ?
How do you answer a whatsapp call directly from a locked iPhone like a conventional call?
When receiving a whatsapp call, I first have to unlock the phone then the call gets dropped... very frustrating.
