Introduction to SMS
SMS, or Short Message Service, is a widely used communication protocol that allows the exchange of short text messages between mobile devices. Since its inception in the early 1990s, SMS has become an indispensable part of our daily communication, evolving alongside technology and transforming how we connect with others.
A Brief History of SMS
The concept of SMS was first developed as part of the Global System for Mobile Communications (GSM) standard. The first SMS was sent in December 1992 by Neil Papworth, a software engineer, who sent the message “Merry Christmas” from his computer to a mobile phone. This simple message set the foundation for a communication revolution.
How SMS Works
SMS allows users to send text messages up to 160 characters in length over mobile networks using the signaling system originally designed for sending alerts and notifications. Here’s a basic overview of how SMS functions:
- The sender composes a text message on their device.
- The message is sent to the SMS Center (SMSC) of the mobile operator.
- The SMSC stores the message and forwards it to the recipient’s device.
- The recipient’s device receives the message and displays it to the user.
Statistics on SMS Usage
SMS usage statistics reveal its significance in modern communication:
- According to Statista, the number of text messages sent per month worldwide exceeded 23 billion in 2020.
- Research by MobileSquared indicates that over 65% of people prefer SMS for brand communication.
- Studies show that SMS open rates are as high as 98%, significantly more effective than emails.
