How WhatsApp Works

If you’re not yet familiar with WhatsApp, it is a popular text and voice messaging app owned by Facebook, Inc. It allows you to share different types of content on the platform, such as pictures, videos, stickers, GIF’s, audio files, and even documents.

To use WhatsApp, you only need your phone’s 2G, 3G, 4G, 5G, EDGE, or Wi-Fi connection to use its services. You can send text messages and make video calls to almost anyone in the world. You can chat with another user alone or with a group of up to eight people.


With WhatsApp, I am able to state my location, post a status for my contacts to view, share contacts, customize my wallpapers, and set my notification alerts. I can use the camera to take pictures and shoot videos from within the app. I can simultaneously send messages to multiple contacts and retrieve my email chat history.

It’s easy to navigate WhatsApp’s interface because it instantly displays the icons for chat and calls once you open the app. Setting up a profile is important so friends and colleagues can identify you. When you tap your name at the top of the screen, you can easily find your picture, your bio, and your name, and when you click on them, you’ll see that they are all editable.

WhatsApp is available on many types of devices, allows users to customize its appearance, supports a variety of files, and maintains a secure and seamless messaging experience.

The total number of users residing in the top three WhatsApp countries exceeds half a billion. The app is home to 573.6 million monthly active users based in India, Brazil, and the US. Meanwhile, the number of WhatsApp messages sent globally is more than 100 billion.

WhatsApp is one of the most-used apps on anyone’s smartphone, including mine, and the numbers agree. App Annie data revealed that the average WhatsApp user on the Android platform uses the app 19.4 hours per month or 38 minutes per day. In the US alone, 50% of WhatsApp users access the messenger service daily.

I think that pioneering free messaging secured the position of WhatsApp in the smartphone usage habits of many people. While Skype excelled at video calling, WhatsApp attracted internet users who preferred text messages. The steep price of SMS text forced people to count the words they type and the texts they send.

WhatsApp freed communicative people from that hassle and allows them to send messages to their heart’s content. You can even send multimedia content and send it to multiple contacts for free. WhatsApp made setting up an account easy by asking for your phone number and nothing else.

WhatsApp’s availability on mobile phones, tablets, and even on Windows Phones, Nokia phones, and Jio in India helped it expand its user base. The app also supports syncing across devices. It exploded further when it introduced video calling and recorded voice messages.

International Users

WhatsApp easily became everyone’s default communication tool because aside from being free, the app has a global presence.

Its services are available in 180 countries. WhatsApp is widely used in Latin American countries, replacing old forms of communication like calling or texting.

Around 93% of people in Brazil actively use WhatsApp to stay in touch with their loved ones abroad. Note that in South America, people often work in neighboring countries where international SMS and voice calls can be costly.

WhatsApp’s Features for Families and Businesses

What is special about WhatsApp and what makes it stand out today is its video calling feature. Before, you had to start a one-on-one voice or video call before you could add other participants, but WhatsApp modified this feature.

To make a group video call, I only need an existing WhatsApp group. To create this group, head over to the Chats tab and click on the three dots in the top right for the More option. Then, tap New Group, but make sure that the group participants are in your contacts.

Select the New Chat icon and then choose New Group. From your group chat, click on the phone icon in the top right, and you can ask up to seven other contacts to join the call. However, if they are not in your contacts, they won't be on the list.

If you just want to use voices only for the call, you can just tap the blue video icon or the phone icon. When the other members receive a group video call, the incoming call notification will display all of the participants who are currently on the call.

WhatsApp for Business Owners

WhatsApp is reaching out not just to groups of friends and families but also to big and small businesses. The WhatsApp Business App provides basic features for small businesses for free, including labels, quick replies, automatic greetings, and a business profile.

What I find outstanding here is that the app allows business owners to connect directly with their customers. The WhatsApp Business API caters to bigger businesses with customer service teams and supports communication solutions like HubSpot, Userlike, and Salesforce.

Business Owners on WhatsApp can use the catalog tool to showcase their products and services. The group chat function for businesses allows them to have up to 256 people participate at one time, and teams can send PDFs and other documents with files as big as 100MB.


With its dynamic functions, navigable interface, easy installation, and free usage, WhatsApp is popular with almost all types of internet users. It is my favorite and go-to messaging app to connect easily with all my friends and family and local businesses.

Whether you are a business owner or someone who loves connecting with friends and family, WhatsApp can meet your communication needs wherever and whenever you are through its advanced collaboration features.
