Despite reports that say millennials believe "phone calls can be burdensome," users of the very popular messaging service WhatsApp are making over 100 million voice calls every day, taking that oh-so-heavy burden head on. With over 1 billion users, WhatsApp is one of the biggest communication platforms in the world, thriving in Europe and Asia where growth has far outpaced growth within the United States.

As The Next Web pointed out, in just over a year of availability with iOS and Android, WhatsApp Calling has likely already surpassed the daily amount of voice calls on Skype, given that the 12-year-old service only has 300 million active users.
