What is SMS & How it works?

What is SMS & How it works

SMS stands for Short Message Service. SMS has been a part of mobile phone users’ daily lives. It is an effortless way to send text messages between devices. Users can send and receive short texts using a phone number.  

Here’s how SMS works: 

  1. The sender enters the receiver’s mobile number and types the text message.
  2. The message the user sends first goes to the Short Message Service Center (SMSC). SMSC is a centralized server responsible for handling all SMS messages.
  3. SMSC monitors the receiver’s mobile number and establishes the right network to deliver messages via a series of signaling messages.

Below are some of the stats:

  • Every day, more than 18 billion text messages are sent worldwide.
  • Every week, 97% of adult Americans send texts, and 95% of those texts are read within three minutes of sending them. 
  • Text message response times typically take ninety seconds, demonstrating the quick speed of SMS communication.

Similarly, SMS is limited to 160 characters. With billions of messages sent daily, SMS has been a universal way of communication for decades. Despite its widespread use, SMS has limitations, one of which is that it does not support multimedia content.

SMS, also known as traditional mobile messaging, works on the signaling route of mobile networks. It adopts the configuration used by the voice calls.

SMSC is one of the most used text messaging services in the world. The receiver receives and delivers the message with a notification. Likewise, SMSC reserves the message until the recipient is available.
