SMS (Short Message Service)

Short Message Service (SMS) is a feature of mobile communication that allows users to send and receive text messages using their phones. Typically limited to 160 characters per message, SMS enables quick and easy communication between individuals, regardless of their mobile network. It gained popularity in the late 1990s and continues to be widely used for personal messages, alerts, and notifications. SMS operates independently of an internet connection, relying instead on the cellular network, making it accessible even in areas with limited internet service.
