WhatsApp is one the most used communication apps in the world with millions of users daily. WhatsApp is most well-known for its group chats but its voice calling feature can be just as important.
WhatsApp allows you to make free voice calls with your contacts. This feature is especially helpful if you have contacts who live abroad. It saves you the high international calling fees that normally would make these calls prohibitively expensive.
This is how you can make a WhatsApp call to one person or a group.
Quick tip: This article focuses on voice calls. WhatsApp also offers video calling.
How to call WhatsApp to one person
You will need to be connected online to make a WhatsApp phone call. You can connect to the internet via Wi-Fi or via a mobile 4G/LTE network.
1. Open WhatsApp, and then in the Chats section tap the conversation you wish to start with the person. You'll need to open a conversation with them if you don't have one.
2. Tap the call icon in the upper-right corner. It looks similar to a phone. WhatsApp will call their number and, if they answer the call, you'll connect on a phone call.
