Whatsapp is an awesome app. Its features are just cool. I am using this app for 1 year. I have not faced any troubles yet. Its features are as follow- chating, sharing, calling and much more fun. The best feature is the calling connectivity, on low range networks like 2G It gives almost the same as on 3G and so on.I wanna say this is just awesome and it is found in almost all smartphones.
