SOS for SMS?
The Short Messaging Service (SMS) is under pressure from apps that can do far more than just send messages. Despite being essential for two-factor authentication and online banking TANs, its overall importance has declined. Messenger services like WhatsApp, with over 2 billion users globally, have become the preferred choice for communication, offering text, image, and video sharing, even for calls. Concerns arise over data privacy as these apps monetize user information, contrasting with regulated local telephone companies.
