Facebook has started testing a mobile calling app 'Hello' on Android, which allows users to connect with Facebook to see the identity and information about callers even if the number is not saved on the phone. Hello connects with Facebook so you can see who’s calling, block unwanted calls and search for people and places.

You can also search for people and businesses on Facebook and call them with one tap.

Facebook said in March that it would add a feature to its messaging app that allows friends to send and receive money through it.
