How would we know if you "qualify"?
Define "overseas".

How do I use WhatsApp Calling?
WhatsApp Calling lets you call your friends and family using WhatsApp for free, even if they’re in another country. Currently, WhatsApp Calling is available on iPhone (on iOS 7 and later), Windows Phone, Android and BlackBerry 10. WhatsApp Calling uses your phone’s Internet connection rather than your cellular plan’s voice minutes. Data charges may apply.
