Whatsapp is a very big social network in the word.My experience with Whatsapp is good.I can chat with my old and new friends very easily through whatsapp just one condition must be fulfill and that is my friend must be available in whatsapp. I can Create group also by 256 member.Not only that I can share any kind of songs picture videos document my location very easily through whatsapp.So whatsapp is a useful medium for me and the best part is its free it just required my data card.moreover I can do voice call and video call also with my friends.So lets come to the disadvantage-big files not able to send through whatsapp.
