Why WhatsApp Is so Popular

WhatsApp was first on the scene and continues to upgrade its services

WhatsApp, the popular messaging and Voice-over-IP service owned by Facebook, helps people send text messages, voice calls, recorded voice messages, video calls, images, documents, and user locations. More than 1 billion people worldwide use WhatsApp to stay in touch.

WhatsApp Was First

When WhatsApp rolled out in 2009, it was the first of its kind. At that time, there was Skype, which excelled for its voice and video calling, but Skype was for the PC and made a late entry into mobile phones. WhatsApp was to free messaging what Skype was to free calling. Although other mobile messaging apps such as Viber and Kik came out later, WhatsApp remained the app to beat.

At that time, WhatsApp wasn’t a VoIP app. It was just for messaging. WhatsApp came on the market with a new communication model. Instead of being perceived as an alternative to Skype, where people had to choose, it was welcomed as a new way of texting that had a welcome place alongside Skype.

WhatsApp Killed SMS

When WhatsApp launched, people were complaining about the price of SMS texts. SMS was costly and limited. WhatsApp solved this problem. With WhatsApp, you could send messages to other WhatsApp users without counting words, without being deprived of multimedia content, and without being restricted to a set number of contacts—all for free. Meanwhile, in some parts of the world, one SMS message could cost as much as a dollar.

Before WhatsApp, mobile carriers often sold separate texting plans, with caps and additional fees, for SMS text messages and for media-enriched MMS messages. After WhatsApp and its competitors broke through, carriers no longer found value in charging for these services. Today, in the United States, its rare for SMS or MMS to be sold separately or individually metered.

You Are Your Number

WhatsApp went one step further than Skype in a certain direction, that of identifying users on the network. It identifies people through their phone numbers. No need to ask for a username. If you have someone’s phone number in your contacts, it means they are already in your WhatsApp contacts if they use the app. This makes it easier for texting than Skype. On WhatsApp, anyone who has your number has you on the network, and you cannot choose to be offline. You also cannot hide behind a fake identity.

WhatsApp Works on Most Platforms

WhatsApp started on Android and iOS mobile phones, and with the explosion of tablets, it made a seamless transition to Android and iOS tablets. WhatsApp widened its user base to include Windows Phones, Nokia and other phones, web, and desktop, and Jio (in India). The app synced across all the supporting devices and rapidly accumulated millions of users.

Expanded Feature Set

WhatsApp’s features were new in 2009. It pleased its users with features that included group chat and the ability to send pictures and other multimedia elements along with messages. In time, as competition increased, WhatsApp added its free-calling feature and became a VoIP giant. Soon, WhatsApp added video calling and recorded voice messages to its offerings.

WhatsApp Is All About Mobility

WhatsApp was made for mobile devices and not for computers, so it had the advantage of not having to adapt to the mobile environment like its competitors that were PC natives. It came at a time that saw a boom in smartphone adoption and an unprecedented shift from the computer to the tablet PC and smartphone. Also, 2G and 3G data became more accessible and cheaper in many places. Although WhatsApp is a free app, data rates apply in some instances.

Time Advantage

WhatsApp launched at a time when people needed what it had to offer. It went unchallenged for a couple of years before real competition came around. By then the network effect had already started, which is the most important factor in its success. Because communications between WhatsApp users are free, using an app with a wide user base is advantageous, and you can't get much wider than WhatsApp's user base.
