The facebook messenger is a instant messaging app to connect our facebook friends, The application provide us to contact with facebook friends, Here we can send them text messages, Photo’s, Gifs, Audio & Videos Clips & Document’s, We can make here voice and videos calls too, One more thing about facebook messenger is the service providing them who also don’t have facebook account, they can also use application by logging by full name & phone numbers. The app is available in Play store android user’s. My experience is just awesome with this app because to connect with friends it’s provide calls with low data as per me. This is usefull app now a days.
