Whatsapp is now a very important part of my life. Its been 5 years now I m useing whatsapp. I genuienly feel it is the best messanger I have ever used. It provides us with fast and instant chatting and many more.
Moreover the quality of this app is very much good indeed. There are many messangers in market but nothing is as good as whatsapp. I would honestly recomand you to use whatsapp.
