Welp! It looks like I can cancel my phone plan, because 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. 

The "push to talk" feature can be used on both Android and iOS phones.

The feature lets Facebook members record and send short audio messages to each other.

To access the feature, open the Messenger app and begin composing a message. Click the plus sign to the left of the text field and then click "Record Voice." Hold the red button, and record your message, letting go when you are finished.

So don't cancel your plan yet, you need your phone carrier for wi fi.:(
