In addition to the usual voice communication, the GSM standard implies a lot of different possibilities. Among them: sending a fax, connecting to the Internet (sending files and e-mail), sending short text messages. It is the latter functionality that will be discussed in this article: SMS - what is it, how does this abbreviation stand for, what features are inherent in this service?
General Description
At the moment, a modern person cannot imagine himself without a mobile device: with its help we solve work issues, communicate with friends and relatives, consult on issues that concern us, find out the necessary information. SMS is a basic service that connects to a number, and one of the most demanded and popular. Through short messages, you can easily send your colleague or relative the necessary data that is quite difficult to perceive by "hearing", for example, address, phone number, etc.
History of occurrence
The idea of exchanging textmessages appeared back in 1989, but then a group of engineers and programmers did not even know that their developments would be called SMS. This led to the fact that after a couple of years it was possible to partially implement this idea. Why partially? The first text message to a mobile phone was sent via a computer. In our country, the functionality of communication through text messages appeared at the beginning of the 2000s. Moreover, in the Moscow region a little later than in others.
How is SMS decrypted?
Many wonder what is hidden under the three letters - SMS. How can you decrypt them? Short Message Service - SMS. The meanings of this abbreviation, translated into Russian, can be reduced to one concept - "Short Message Service".
Key Benefits of Texting
- the ability to send information to another person, which will be stored in his corresponding journal - at any time he will be able to view the received data;
- you can transfer data even if the recipient's mobile device is turned off - as soon as the subscriber registers on the network (provided that the waiting time is not exceeded) - the message will be delivered;
- many organizations use SMS as an advertising channel: calling people and offering 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 for those whowho is roaming.
As for the delivery of a message to a number that is not online (for example, the smartphone is turned off or the SIM card is out of network coverage), it should be borne in mind that each operator has the time during which the message can be on the server and wait for dispatch, individually. If the subscriber has not been registered in the network for a long time, the message will be deleted.
How SMS works
SMS is not a direct way to interact with another person, unlike a voice call, when a connection is established directly between two devices. After the message is sent by the subscriber, it first goes to the server, which, in turn, checks whether it can be delivered to the specified number. If the check result is positive, the message is sent to the addressee. Otherwise, it stays on the server for some time, waiting to be sent.
What is needed for the SMS service to work on a mobile phone?
Do I need to make any settings to use the SMS service? This is what it is - it was discussed earlier. On modern smartphones and tablets, manual setting of service parameters is not required. They are detected automatically after the SIM card is inserted into 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 you have problems sending or receiving text messages, mobile operatorsit is recommended to check if the SMS center number has gone astray in the service settings - if necessary, it must be corrected. For each operator and region, a personal number is set. 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.
Shipping methods
SMS is a popular way to communicate. With the development of technology, the transfer of text information has become possible not only between devices using the GSM standard, but also in other ways:
- via the Internet (a similar feature is available on the website of telecom operators; despite the fact that the distribution is anonymous, the user will still have to log in to the resource);
- through special programs (in fact, they also carry out mailing through the portals of mobile operators);
- through SMS services (there are a number of organizations that, for a fee, carry out mass mailings, usually of an advertising or informational nature).
Conclusion
In the current article, we have considered the SMS service. This is one of the most popular services used by cellular subscribers. In particular, this is due to the fact that using the service is quite simple, cheap, fast and convenient. Being a basic service on each number, SMS does not require special conditions for functioning - it is enough to have the necessary amount to send a text and be in the coverage area of the operator's network.
