general description
At the moment, a modern person cannot imagine himself without a mobile device: with it, we solve work issues, communicate with friends and relatives, consult on issues that concern us, and find out the necessary information. SMS is a basic service that connects to a number, and one of the most popular and popular. Using short messages, you can easily send to your colleague or relative the necessary data that is difficult to perceive by “hearing”, for example, address, phone number, etc.
History of occurrence
The idea of ​​text messaging appeared in 1989, but then a group of engineers and programmers did not even realize that their work would be called SMS. This led to the fact that after a couple of years it was possible to partially realize this idea. Why partially? The first text message to the mobile device was sent via computer. In our country, the functionality of communication through text messages appeared at the beginning of the zero. Moreover, in the Moscow region a little later than in others.

Key Benefits of Text Messaging
- the ability to send information to another person that will be stored with him in the appropriate journal - at any time he will be able to view the data received;
- You can transfer data even if the recipient’s mobile device is turned off - as soon as the subscriber registers in the network (provided that the waiting time is not exceeded) - the message will be delivered;
- many organizations use SMS as an advertising channel: to ring up people and offer them some services and goods is quite expensive and not always convenient for both parties, which cannot be said about SMS mailings;
- the cost of sending a text message is less than a voice call, in particular, it is beneficial to those who are in roaming.
As for the delivery of a message to a number that is not on the network (for example, the smartphone is disconnected or the SIM card is outside the network coverage area), it is worth considering that each operator has time during which the message can be on the server and wait for sending, individually . If the subscriber has not been registered in the network for a long time, the message will be destroyed.
SMS working principle
SMS is not a direct way of interacting with another person, unlike a voice call, when communication is established directly between two devices. After the message is sent by the subscriber, it goes first to the server, which, in turn, checks whether it can be delivered to the specified number. If the test result is positive, the message is sent to the addressee. Otherwise, it remains on the server for some time, waiting to be sent.
What is necessary for the SMS service to work on a mobile phone?
Do I need to make any settings to use the SMS service? What is it - was considered earlier. On modern smartphones and tablets, manual setting of service parameters is not required. They are detected automatically after the SIM card is inserted in the device slot. In some cases, it takes some time for the correct connection of communication services. As a rule - no more than a day. If there are problems with sending or receiving text messages, mobile operators recommend checking to see if the SMS center number is incorrect in the service settings - if necessary, you need to adjust it. A personal number is set for each operator and region. You can clarify it on the official resource of the cellular company, on the page with the description of the service or through the contact center.

- through special programs (in fact, they also distribute through the portals of mobile operators);
- via SMS services (there are a number of organizations that carry out mass mailings for a fee, usually of an advertising or informational nature).
