tekstiviestintään

Tekstiviestintä, often abbreviated as SMS (Short Message Service), refers to the transmission of short text messages between mobile phones. It is a fundamental communication method that emerged in the early days of mobile telephony. The first SMS message was sent in 1992. Tekstiviestintä is characterized by its brevity, typically limited to 160 characters per message, although modern systems and concatenation allow for longer messages to be sent as a series of standard SMS units.

The technology behind tekstiviestintä relies on the signaling channels of the mobile network, allowing messages to be sent even when a voice call cannot be established. This makes it a reliable method for quick updates, notifications, and brief conversations. Over time, tekstiviestintä has evolved to support multimedia messages (MMS), which can include images, audio, and video, although the term "tekstiviestintä" traditionally refers to plain text. Despite the rise of instant messaging applications, SMS remains a widely used and accessible form of communication globally due to its ubiquity and the fact that it does not require internet access. It is also commonly used for automated alerts, two-factor authentication, and marketing communications.
