Textmeldungen
Textmeldungen, also known as text messages or SMS (Short Message Service), are a communication method allowing the transmission of short text-based messages between mobile phones. These messages are typically limited in length, originally to 160 characters, though modern systems and concatenated messages can accommodate longer texts. Textmeldungen function over the cellular network, utilizing dedicated channels for message transmission. They are distinct from instant messaging applications that rely on internet data.
The technology behind textmeldungen was developed in the late 1980s and became widely adopted in the 1990s.
