WhatsApp is a messaging app that is used by millions of people around the world. It has been in the market for over two years and it has already become one of the most popular messaging apps on Windows Phone. If you are a Windows Phone user, then you should definitely check out WhatsApp. It is an incredibly versatile messaging app that can be used to communicate with friends and family, as well as to send messages for business purposes. One of the great things about WhatsApp is that it can be used in tandem with another messaging app, such as Facebook Messenger or Google Hangouts. This way, you can easily keep all your communication options open at the same time. To use WhatsApp on Windows Phone, first open up your Settings and then select “Messenger” from the left-hand menu. Then select “WhatsApp” from the list of apps and hit “Create new message”. You will be asked to enter your phone number and email address. You can also choose to have WhatsApp send messages only when there are no other active messages in your chat history. Once you have created a new message, hit “Send” and enjoy using WhatsApp!
