Facebook Messenger is an official Facebook app for those who don’t need to check the newsfeed and only want to communicate with people.
So you won’t get any issues while chatting or sending files to other users!
Viber also works as Skype giving its users free voice and video calls.
Like Skype, Telegram syncs across all your devices making it possible to start a conversation on one device and continue it on another.
Unfortunately, it doesn’t have an option to make voice or video calls.
You can dictate the message with voice if it is more convenient for you, make groups, make voice calls and send media with this app.
