WhatsApp is now handling more than 100 million voice calls every day, a sign of the feature’s popularity since its launch last year.
Voice calling was launched in April last year and gives users a way to make international calls via their data plan.
“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,” the firm said.
Reports say WhatsApp calls have probably surpassed the number of daily voice calls on Skype, given that the latter only has 300 million active users.
The news comes around five months after the Facebook-owned company said it had hit the 1 billion user milestone.
At the time, Facebook CEO Mark Zuckerberg revealed that the app supports 53 languages, with 1.6 billion images and 250 million videos shared on it everyday.
Back in January, co-founder and CEO Jan Koum said he was able to leverage Facebook’s infrastructure to launch voice calls, which meant they didn’t have to buy and manage a large number of servers.
When asked if WhatsApp would introduce video calling, a feature Facebook Messenger already has, Koum’s response was “we’ll see, maybe,” adding he did not want to talk about any service until it was certain as the company raised expectations around voice calls only to experience delays in its launch.
