I am using what’s up for last 5 months. It’s a wonderful app. One day my brother installed this app in my mobile. Up to that I am not aware of this App. After a week I got a message from school friend. She is the only school friend still in touch with me. I missed all my other school friend contact. We will chat daily and share everything like photos and videos.
Then she created group and added me day by day group strength was increased. I am really happy to see my entire friend at a time. The main advantage in this app is with less data you can do both send and receive media file in this. Every day I am chatting with my school friends. I felt like I got my school days back.
