In this article we explain how to make a phone call using the popular WhatsApp app.
How to have a WhatsApp conversation
WhatsApp uses data instead of cellular voice services to place text messages and voice calls. That means you can use it even if you’re traveling internationally or somewhere without cellular service. In fact, WhatsApp is popular among international travelers, who rely on WhatsApp to avoid having to buy international data plans.
As long as you have a Wi-Fi connection, you can have a WhatsApp conversation. If you don't have Wi-Fi, WhatsApp will use data from your mobile plan, which may result in data charges.
WhatsApp, on the other hand, is also easy to use as it uses your existing address book and you don't have to search for people based on their username or email address.
