SMS

SMS, or Short Message Service, is a text-based communication method that allows people to send and receive short messages on mobile phones. Typically limited to 160 characters, SMS can be used for personal messages, alerts, and notifications. It was developed in the 1980s and became popular in the 1990s, enabling quick and convenient communication without needing internet access. Unlike traditional voice calls, SMS messages can be sent and stored, making them a flexible way to connect with others. Today, SMS remains widely used, even with the rise of messaging apps.
