Privacy and security is an essential factor today. Given the highly digitized world in which we live, it is a real threat that our data leaks over the Internet. However, the danger sometimes does not have to come through a cyber attack, but can be generated through an element as basic as the SIM card.
This element is a fundamental part of our mobile phone, since without it the possibilities are considerably limited. In a few words, it could be said that it is a kind of ID of the device that associates it with a specific number and operator, as well as more specific personal information.
This implies that if a person with malicious interests were to get hold of it, it could cause us serious problems that should be avoided. The point is that the individual in question does not even need to steal or obtain the SIM card in any way. Knowing the ICC number is enough to cause unwanted situations.
What is the ICC number
This 19-digit code is a way to identify the card and makes it unique. In the case of smartphones, the sequence always begins with 89, since it is an indicator that indicates that it is a SIM aimed at telecommunications. Then, the number 34 occupies the next two spaces. This shows that it is located in Spain, while the next two relate it to a company. The rest of them are decided by the operator to provide a unique and differentiated “look” from the rest.
It is very important to have the numerical key written down somewhere. Mainly, because it is a mandatory requirement to execute a duplicate of the card, a portability to another company or a change of card size.
why is it dangerous
This ICC code is printed on the SIM card of the terminal itself, although it may be impossible to consult it over time due to wear. Another option is that, when transforming it into a smaller unit such as a microSIM, it has been lost. Either way, you can get it back by calling your carrier or downloading an application for your computer that helps you find out.
Be that as it may, it is vitally important that you do not show it. After what is mentioned in the previous paragraphs, you can already get an idea of the risk you are taking on. If the number falls on the wrong person, they could carry out a copy of the SIM card. Which would cause all the data inside it to also become part of it. An effective way to avoid this problem is to bet on those known as eSIM that integrate brands such as Samsung. These are virtual and for this reason they cannot be removable in any way.
A simple data can become extremely risky. That is why it is never advisable to remove the SIM card from the phone. It is an activity that is not necessary to carry out in hardly any case, unless you are dealing with a professional who is trying to solve a problem. Otherwise, you must refrain at all times from teaching it in a place full of people. It is possible that without realizing it, an external person obtains the number.
