Why are SMS messages not being sent on WhatsApp - briefly?

SMS messages are not sent on WhatsApp because the platform operates exclusively over the internet and does not have the capability to send traditional SMS or MMS messages.

Why are SMS messages not being sent on WhatsApp - in detail?

SMS messages are not sent directly through WhatsApp due to several reasons that relate to the app's design, functionality, and security measures.

Firstly, WhatsApp is primarily designed as an internet-based messaging application. It uses data connectivity, either Wi-Fi or mobile data, to send and receive messages, photos, videos, and other media. This allows users to communicate with each other without incurring SMS fees, which can be particularly beneficial for international communication where SMS charges are often high.

Secondly, WhatsApp's end-to-end encryption ensures that messages sent through the app are secure and private. This level of security is not available through standard SMS, which is why WhatsApp does not support sending traditional text messages. End-to-end encryption means that only the sender and recipient can read the messages, providing a higher level of privacy and security for users' communications.

Thirdly, WhatsApp offers a wide range of features beyond simple text messaging, such as voice and video calls, group chats, multimedia sharing, and status updates. These advanced functionalities are not supported by traditional SMS services, which are limited to text messages with a character limit. By focusing on data-based communication, WhatsApp can provide a more comprehensive and rich user experience.

Lastly, WhatsApp's business model is built around its internet-based messaging platform. The company generates revenue through various means, including in-app purchases for additional features or services, and potential future monetization strategies that rely on data connectivity. If WhatsApp were to support SMS messages, it would need to integrate with telecommunication networks, which could complicate its business model and potentially introduce new costs and complexities.

In conclusion, the primary reasons why SMS messages are not sent through WhatsApp include the app's focus on data-based internet communication, the security measures provided by end-to-end encryption, the advanced features offered beyond simple text messaging, and the business model that supports its revenue generation strategies.
