Short Message Service (SMS)

Short Message Service (SMS) is a text messaging technology that allows people to send brief messages, typically up to 160 characters, between mobile phones or devices over cellular networks. It operates independently of internet data, using existing mobile network infrastructure to deliver messages quickly. SMS is widely used for personal communication, alerts, and notifications because of its simplicity, reliability, and broad compatibility across devices and networks. It doesn't require a smartphone or data plan, making it accessible and effective for reaching users instantly.
