Facebook has begun to test a feature for its Messenger app that lets users call each other.
For now the test is limited to users in Canada who have the most recent version of the Facebook Messenger app downloaded on an iPhone, Facebook said Thursday.
The feature works much like a Skype call, but there is no video option. The calls can be made via Wi-Fi or on the phone's cellular network using its data plan.
Separately, the social network has released a worldwide update to its Messenger app adding a "push to talk" feature that can be used on both Android and iOS phones.
