Among them: sending a fax, connecting to the Internet (sending files and e-mail), sending short text messages. It is about the latest functionality that will be discussed in this article: SMS - what is this, how does this abbreviation stand, what features are inherent in this service?

general description

At the moment, modern man can not imagine himself without a mobile device: with his help we solve working issues, communicate with friends and relatives, consult on issues of concern to us, learn the necessary information. SMS is a basic service that connects to the number, and one of the most popular and popular. Through short messages, you can easily send to your colleague or relative the necessary data that is difficult to perceive on the "rumor", for example, address, telephone number, etc.

History of occurrence

The idea of exchanging text messages appeared back in 1989, but then a group of engineers and programmers did not even guess that their workings would be called SMS. This led to the fact that a couple of years later it was partially realized this idea. Why partially? The first text message to the mobile device was sent by computer. In our country, the functional communication through text messages appeared at the beginning of the zero. And in the Moscow region a little later than in others.

How is SMS decrypted?

Many are wondering what lies beneath the three letters - SMS. How can they be decrypted? Short Message Service - SMS. The meaning of this abbreviation in Russian translation can be reduced to one concept - "Short message service".

The main advantages of text messages

• The ability to send information to another person, which will be stored in his or her relevant journal - he will be able to view the data at any time;
• You can send data even if the destination's mobile device is turned off-as soon as the subscriber's registration on the network occurs (provided 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 quite costly and not always convenient for both parties, which can not be said about SMS-sending;
• 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 delivering a message to a number that is not on the network (for example, the smartphone is disabled or the SIM card is out of the network coverage area), it should be borne in mind that for each operator the 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 deleted.

The principle of SMS operation

SMS is not a direct way of interacting with another person, in contrast to a voice call, when the connection is established directly, between the 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 result of the test is positive, the message is sent to the addressee. Otherwise, it remains on the server for some time, waiting for sending.

What is necessary for the SMS service to work on a mobile phone?

Do you need to make any settings for using the SMS service? This is what - 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 installed in the device slot. In some cases, some time is required to connect the communication services correctly. As a rule - not more than a day. If there are problems with sending or receiving text messages, cellular operators recommend checking whether the number of the SMS center has strayed in the settings of the service - if necessary, it needs to be adjusted. A personal number is set for each operator and region. You can specify it on the official resource of the cellular company, on the page with the description of the service or through the contact center.

Ways of sending

SMS is a popular way of communication. With the development of technologies, the transmission of textual information became possible not only between devices through the GSM standard, but also in other ways:

• Via the Internet (a similar possibility is available on the site of telecom operators, even though the dispatch is anonymous, the user still has to log in to the resource);
• Through special programs (in fact, they also send out via the portals of mobile communication operators);
• Through SMS-services (there are a number of organizations that perform mass mailings for a certain fee, usually advertising or informational nature).
