Why don't SMS messages send from WhatsApp - briefly?
WhatsApp does not support sending traditional SMS messages because it operates on a different messaging protocol called WhatsApp Messaging (WAM). Instead of using the mobile carrier's SMS network, WhatsApp uses an internet connection to send and receive messages, making it more efficient and cost-effective for users.
Why don't SMS messages send from WhatsApp - in detail?
WhatsApp, a popular messaging platform owned by Meta (formerly Facebook), has revolutionized communication by providing users with a seamless and efficient way to send text messages, make voice and video calls, and share multimedia content. One feature that sets WhatsApp apart from traditional SMS services is its reliance on the internet for message delivery. This dependency raises the question: why don't SMS messages send from WhatsApp?
At the core of this issue lies the fundamental difference between how SMS and WhatsApp messages are transmitted. Traditional SMS (Short Message Service) operates through cellular networks, utilizing the Global System for Mobile Communications (GSM) or Code Division Multiple Access (CDMA) standards. These messages are sent over the network's control channel, which is independent of internet connectivity. In contrast, WhatsApp messages are transmitted over the internet using data packets, similar to email.
WhatsApp employs end-to-end encryption for its messages, ensuring that only the intended recipients can read them. This advanced security measure requires a constant and reliable internet connection to function properly. When internet access is unavailable or disrupted, WhatsApp cannot deliver messages as it lacks the fallback mechanism of traditional SMS.
Moreover, WhatsApp's business model revolves around offering free messaging services to users. By leveraging the internet for message delivery, the company avoids incurring costs associated with traditional SMS services, which are typically charged by mobile carriers. This cost-effective approach allows WhatsApp to provide its service without imposing fees on users.
Additionally, WhatsApp's integration with smartphones and other internet-enabled devices enables a richer messaging experience. Users can send multimedia content such as images, videos, documents, and even make voice and video calls directly through the app. These features are not supported by traditional SMS services, which are limited to text messages of up to 160 characters.
In summary, WhatsApp does not send SMS messages because it operates on a different messaging protocol that relies solely on internet connectivity. This approach enables WhatsApp to offer secure, cost-effective, and feature-rich communication services to its users worldwide.
