SMS functionality: an essential communication tool
Share :
Introduction
SMS (Short Message Service) functionality is one of the oldest and most popular methods of communication on cell phones. Since its launch in the 1990s, it has remained an essential tool, even in the face of modern technologies such as RCS (Rich Communication Service) or instant messengers like WhatsApp.
SMS enables short text messages to be sent between telephone numbers. In addition to its simplicity, it offers advanced functionalities, such as sending multimedia content via MMS (Multimedia Messaging Service).
For companies, SMS is a key resource for marketing strategies, customer relationship management and security (with SMS OTP). Whether for promotions or to keep in touch with friends and family, SMS remains indispensable for its flexibility and accessibility.
What is an SMS ?
SMS definition
SMS, or Short Message Service, is a text messaging service enabling the exchange of short text messages between mobile devices (usually a telephone). A message can contain up to 160 characters. The service is based on standardized communication protocols, enabling cell phones to transmit SMS messages via cellular networks.
History and development
The origins of SMS date back to the first GSM (Global System for Mobile Communications) standards of the 1990s. The very first SMS was sent in 1992 by Neil Papworth (it read "Merry Christmas" and was sent from a computer to a Vodafone phone). The original purpose of the service was to enable cell phone operators to send alerts to their customers.
Based on the SS7 signaling protocol, SMS has rapidly gained popularity as a means of text communication between cell phone users.
Over time, SMS has adapted to advances in network technology, including today's 5G networks. The creation of SMS gateways (SMSC) has also enabled messages to be transmitted via the Internet, facilitating communication with computers, landlines and even satellites.
In 2002, MMS (Multimedia Messaging Service) was introduced as an extension to SMS, enabling messages to be sent containing images and other multimedia content.

How SMS is sent
When you send an SMS, the process is as follows:
- Message composition: you compose your message on your phone or via a sending platform.
- Transmission to base station: the message is sent to the nearest cellular base station.
- Via the SMS center (SMSC): the antenna transmits the message to the SMSC, which stores it temporarily if the recipient is unavailable.
- Delivery to the recipient: once the recipient can be reached, the SMSC forwards the message to his or her telephone.
This extremely rapid process makes SMS a virtually instantaneous form of communication.
