How to use WhatsApp

Why is WhatsApp so popular?

If you look at the last few years, WhatsApp is still not as popular as it is now, many people use other applications such as Facebook or BBM as a means of communication. So what made WhatsApp as popular as it is now?

Low cost

WhatsApp has become popular in many areas due to its low cost of use. At that time, telephone providers in many countries charged a text message or limited the number you could send. Since all you need to use WhatsApp is an internet connection, this is a more attractive alternative to texting.

Simplicity and support between devices

In some countries, there are many people who use iPhone, iMessage is the default messenger for many people, it will be activated automatically when you send a text message to someone who also has an iPhone. But because Android is more widely used around the world, WhatsApp has a solution to solve this problem.

WhatsApp remains top notch for simplicity and flexibility. All users need to do to send messages to someone is their phone number, so you don’t have to worry about connecting to Facebook or using an Apple device. Sending SMS, calling and sharing photos in one place without ads is an interesting thing about WhatsApp.

SMS (and MMS, which is used to send multimedia messages) are also outdated. SMS is still limited to 160 characters per text, and MMS has strict file size limits that affect modern videos and images. WhatsApp is a modern method of sophisticated messaging nowadays.

End-to-end encryption

In addition to the low cost and high flexibility. WhatsApp also has guaranteed security with end-to-end encryption features. This means that the messages you send with the service can only be read by their intended recipients.

Many other messaging services, such as Telegram, use client-server encryption by default. This means that your messages are encrypted in transit, but pass through the company’s servers and are re-encrypted at that time. In theory, someone in the company with the decryption key could read or edit your messages.

Despite end-to-end encryption, many people don’t trust WhatsApp because Facebook owns it. If you decide to use WhatsApp, it’s up to you. But many people / friends around the world most likely use WhatsApp, so you should definitely use it if you want to talk to them.


So WhatsApp is a solid application and makes it the most used messaging application in most parts of the world. It’s not perfect, mainly because it’s owned by Facebook. But it is an important way to talk to many people around the world.
