WhatsApp voice call has been in use for about a year now. It is certainly the best way to send text messages for smartphone user and it got even better when the voice calling feature was baked into it. Users can keep in touch with family, friends, and colleagues without boundary limitations like different countries, in a very cost-effective manner.
Sure there are other Over The Top (OTT) services like Skype and Viber that more or less do what WhatsApp does. Except WhatsApp has a simple registration process, works well on even base level mobile devices that are affordable to many. For these reasons and more, WhatsApp has scaled its users at rates to be envied by its competitors.
With the Voice Call feature, WhatsApp has ushered in a new era of cheap VOIP services, enabling users to talk with each other at really affordable costs. So much so that it is registering over 100 million voice calls per day.
“Today, more than 100 million voice calls are made every day on WhatsApp – that’s over 1,100 calls a second! We’re humbled that so many people have found this feature useful, and we’re committed to making it even better in the months to come.” – wrote WhatsApp in a blog post.
The app now has over a billion users worldwide and has proven to be an invaluable way for people living in different countries to stay in touch. The voice calling feature is especially useful when messages are just not good enough.
Obviously, these stats are unsettling to telecom operators. As an OTT service, WhatsApp relies on their infrastructure (internet services) to get to the users and in return, the app denies them revenue from both voice calls and SMS services.
Many people with smartphones (which are already on the fast track to proliferate the market) prefer sending WhatsApp messages to traditional SMS and MMS. If WhatsApp voice calling, continue to grow popular, that will present a big problem to telecoms paying for the infrastructure services (internet) the app is hosted on.
