Sisusõnumi

Sisusõnumi is an Estonian term that translates to "content message" or "content notification." It refers to a short, often unsolicited, message that appears on a mobile device, typically a feature phone, intended to deliver information or entertainment. These messages are distinct from standard SMS (Short Message Service) as they are usually part of a subscription service or a promotional campaign.

Historically, sisusõnumid were a popular way for users to subscribe to services like horoscopes, news alerts, jokes, or ringtones. This was often done by sending a keyword via SMS to a specific shortcode. Once subscribed, users would receive regular content messages, usually charged on a per-message or per-week basis. The revenue generated from these services was typically shared between the content provider and the mobile network operator.

The rise of smartphones and mobile internet has significantly diminished the prevalence of sisusõnumid. With the advent of dedicated apps, mobile websites, and a wider range of digital communication platforms, consumers have moved towards more interactive and data-driven content consumption. While still present, sisusõnumid are less common than they were in the early to mid-2000s, and their usage is often associated with older mobile technologies or specific niche services. Regulations and consumer awareness regarding subscription management have also evolved, impacting how these messages are delivered and managed.
