Today no one can be surprised by the presence of a mobile phone, but quite recently, some 15 years ago, this type of communication was not just a luxury, only a few could afford it. The development of mobile communications is moving forward by leaps and bounds. Almost every month, some global brand offers its new products in the field of mobile communications. Everyone already knows how to use it, but not everyone knows that the concept of IMEI is closely related to the concept of a mobile phone. What is this term? In this article, we will look at its meaning.
So, IMEI - what is it? IMEI is an abbreviation, it means the unique number of the mobile device. It is decoded as follows - International Mobile Equipment Identifier (International Mobile Equipment Identifier). It consists of 15 digits, in the first two digits the country of origin is encrypted, in the next 6 the model code of the device is encoded, another six digits are the individual number of this particular phone,the last 15th is a spare identifier. Now we know the meaning of the IMEI concept. What does this give us, how is this code useful? We will talk about this a little later, but for now we will analyze how to determine the IMEI of your mobile phone. First of all, you need to know that this number is written on the box of your phone. Secondly, it is indicated on the body of the device itself - under the battery. If you do not have a box at hand or you are too lazy to pull the battery out of the phone, you can recognize it by dialing the code 06on the phone's keyboard, and the number will be displayed on the phone screen.
And now let's talk about why it is needed, what is useful and what is "inconvenient". When buying a new or used mobile phone, you can perform an operation such as checking the IMEI. The phone is checked against the database of your country, and all the information is immediately visible to you: whether it was brought into the country legally or not, whether it is “clean” or stolen. Also, when a mobile terminal is connected to the mobile operator's network, its individual number is transmitted. What is it for? The main reason is to prevent unauthorized use of your machine. For example, if your phone is stolen, law enforcement agencies with the help of mobile operators can easily figure out your handset. Of course, this is very good for honest citizens, but for those whose activities balance, as they say, on the edge, and for those who have long crossed it, this number is a serious hindrance. Of course, there is no talk about the secrets of the special services in this article, we will only slightly raiseveil.
Law enforcement agencies have a number of elementary methods to calculate IMEI. What does it give them? Knowing this number allows the special services to listen not only to the SIM card, but also to the device itself. This is very important, since especially advanced criminals often change SIM cards, and in some cases they even use disposable ones, and after one important conversation they destroy the chip. Some readers will be interested in whether it is possible to change the IMEI. The answer to this question is unequivocally no. Although earlier in older models of phones it was possible to reset the device number programmatically. Such a phone had a "zero" name, in modern mobile phones, software reset is impossible. There is a way to replace the processor unit with a new number, but such a procedure will be more expensive than the device itself. It's easier to get a new phone.
