Textaskilaboð

Textaskilaboð, commonly known as SMS (Short Message Service), refers to text messages sent between mobile phones. This technology allows users to send and receive short alphanumeric messages over cellular networks. Initially, SMS messages were limited to 160 characters, a constraint that influenced the development of abbreviations and shorthand in written communication. Over time, the character limit has been extended, and modern devices support longer messages through protocols like MMS (Multimedia Messaging Service), which can include images, audio, and video.

The infrastructure for text messaging relies on a dedicated signaling channel within the cellular network. When a user sends an SMS, the message is routed through the Short Message Service Center (SMSC), which then delivers it to the recipient's phone. This system operates independently of voice calls, allowing messages to be sent and received even when the recipient's phone is busy or out of service range, as it is stored by the SMSC until delivery is possible. Textaskilaboð has become a ubiquitous form of communication, valued for its speed, simplicity, and accessibility across a wide range of mobile devices.
