It works just like text messaging, but with one crucial difference – the messages are sent over the internet, rather than over the phone network. This means messages are free to send, even if you attach photos, videos or audio files.
WhatsApp offers greater security and privacy than SMS.
WhatsApp's end-to-end encryption is one of its most noteworthy features, as many people trust it over traditional SMS. Only a few other apps (Signal being one of them) can offer similar online safety to its users.
Each message sent through WhatsApp Business API is a fraction of the cost of sending a text message. You can easily form groups, share files or even receive files from your customers. WhatsApp is much safer as it has end-to-end encryption, making it more secure.
Drawbacks or disadvantages of Whatsapp
➨There is no option to hide from particular users. ➨It is not possible to send messages into normal inbox of the mobile phone. ➨There is a risk of anyone reading the message meant for you only.
WhatsApp is still far more secure than regular non-encrypted texting, because messages cannot be read while they are being transmitted from phone to phone. The message is sent from the sender device to the nearest cell tower when you send an SMS message. The message is sent to an SMS center from that cell tower (SMSC).
If you like functional applications, you might favor WhatsApp with its 1,024 group size limit and 2GB file transfer cap. For a more aesthetic, dynamic, and entertaining experience, iMessage makes the most out of the Apple ecosystem and allows you to link different services and features.
No, WhatsApp calls and messages do not show up on your phone bill. WhatsApp uses the internet to send and receive calls and messages, rather than your cellular network, so they don't appear on your phone bill as cellular usage.

WhatsApp has always allowed anyone with your phone number to message you or add you to a group by default. This is similar to how anyone can send you an SMS or email if they have your contact information.

WhatsApp uses your cellular data to make "calls," which are actually voice chats. You can always make free calls with an unlimited cellular data plan, or if you use WhatsApp over Wi-Fi.

“WhatsApp is far more private and secure than iMessage, with end-to-end encryption that works across both iPhones and Android, including group chats. With WhatsApp you can also set all new chats to disappear with the tap of a button. And last year we introduced end-to-end encrypted backups too.
