Short Message Service
Short Message Service (SMS) is a technology that allows mobile phones to send and receive brief text messages, typically up to 160 characters. It works by transmitting messages over the cellular network, using designated communication channels separate from voice calls. SMS is widely used for personal communication, notifications, and alerts because of its simplicity, reliability, and quick delivery. It doesn't require an internet connection; instead, it relies on standard mobile network infrastructure, making it accessible across nearly all mobile devices and networks worldwide.
