Description: GSM-SMS, which stands for Short Message Service in GSM networks, is a technology that allows the sending and receiving of text messages over mobile networks. This service is based on the GSM standard (Global System for Mobile Communications), which was developed in the 1980s and has become one of the cornerstones of modern mobile communication. GSM-SMS enables users to send messages of up to 160 characters, facilitating quick and efficient communication between mobile devices. Over the years, SMS has evolved, allowing not only communication between users but also integration with applications and services, such as security alerts, service notifications, and marketing. The simplicity and accessibility of SMS have made it an essential tool in everyday life, used by millions of people worldwide. Additionally, its asynchronous nature allows messages to be sent and received without the need for both parties to be available at the same time, making it a highly versatile means of communication.
History: The Short Message Service (SMS) was developed in the 1980s as part of the GSM standard, which was introduced in 1991. The first SMS message was sent in 1992 by Neil Papworth, a software engineer, who sent the message ‘Merry Christmas’ from a computer to a mobile phone. Over the years, SMS quickly gained popularity, becoming a common form of communication among mobile phone users. In the 2000s, SMS solidified as a mass communication medium, and its use expanded to commercial and marketing applications. With the rise of smartphones and instant messaging apps, SMS usage has declined, but it remains relevant in many areas, especially in two-factor authentication and emergency alerts.
Uses: SMS is used in a variety of applications, including personal communication between friends and family, as well as in the business sector to send notifications, reminders, and promotions. It is also common in two-factor authentication, where verification codes are sent to users to enhance the security of their accounts. Additionally, many organizations use SMS to send emergency alerts and critical updates to their employees or the general public.
Examples: A practical example of SMS usage is the sending of security alerts by banks, informing customers about suspicious transactions. Another example is the use of SMS for account verification in online services, where a code is sent to the user’s phone to confirm their identity. SMS is also used in marketing campaigns, where companies send promotions and discounts directly to customers’ mobile phones.
