SMS i.e. Short message service is the communication medium between the Sender and receiver where the sender sends the messages and the receiver receives the text messages. We can access messages on cellular phones, and mobile phones anywhere in the world without the use of an Internet connection. In this article, we will cover a brief explanation of SMS.
What is an SMS?
It is a standardized communication protocol that is used for the exchange of text messages between mobile devices. It is one of the most widely used data applications. One can send SMS using a smartphone, any other mobile phone, or a computer system equipped with the web. The maximum length that a text message can have is 160 alpha-numeric characters. In the current scenario, the SMS facility is supported by GSM, CDMA, and TDMA mobile networks. The facility of SMS is provided by all the telecommunication companies like Vodafone, airtel, idea, etc.

History of SMS
The text message facility was first added to the mobile devices in the early 1980s. The action plan GSM for providing the services available to public data networks also to the mobile systems was approved in December 1982. According to this plan, the exchange of text messages was allowed either via mobile stations or via handling stations. Finally, the concept of SMS was thus developed in Franco-German cooperation by Friedhelm Hillebrand and Bernard Ghillebaert in 1984. The main idea behind the SMS concept was to use telephone optimized systems and to thus transport messages by making the use of signaling paths. The maximum length of text messages to be of 160 alpha-numeric characters was decided by Friedhelm Hillebrand.
How SMS work?
As we know, SMS is just about sending and receiving text messages, but you know how the sender sends the message and the receiver gets the message. Let's take an example: suppose Pooja sends a message to Priya, "Hey Priya, please come home at 2 pm for self-study." Pooja is the sender, and Priya is the receiver.
Here are the approach how this message works-
- First, the sender message is converted into a character encoding format of 7-bit.
- Then, the sender's mobile phone sends the text to the Cell tower, after that when the Cell tower successfully receives the message it transfers the message to the SMS center.
- After that SMS center will send the sender message to the receiver's nearby tower. Once the Cell tower successfully receives the message then it will be received from the receiver device.
- After that receiver phone converts the encoded text into the original message then finally the message will get in original format and successfully received the original message in the receiver's device.
