WhatsApp users are now making over 100 million calls every day, which translates to over 1,100 calls per second. The popular messaging service crossed 1 billion users earlier this year, with recent reports stating that the app is now used by 95% of all smartphone users in India and 94% of smartphone owners in Brazil, two of its largest markets.


The milestone highlights WhatsApp's importance in growth markets, where the service is becoming the go-to platform for communication. Making or receiving voice calls on WhatsApp is very straightforward, and the feature works over Wi-Fi, 4G, 3G, and even 2G data connections. There's even an option to reduce voice clarity to reduce bandwidth usage, which is an added bonus for those on metered connections.
