This is the best massanger ive ever used. No ads, no need to download stickers or else. The most used smartphone aplication all time. Theres no point of smartphone if you dont have whats app on it. I originally used this app to talk to family and friends.
It just changed the way of communication. All people in my city use this app. So, we can easily chat each other. It very usefull for sending photos, videos and audio to anyone. The sound quality during a call is amezing. The only bad thing is youll get addicted to it otherwise its the best to use.
