Making the same phone SIM card as others can eavesdrop on the other party's phone, see his information, and see where he is. There are countless small advertisements. Today, the reporter proved through experiments and consultation with professionals that cloning a mobile phone SIM card cannot be turned into a bug.
Many people have seen small advertisements on the Internet that make SIM cards to help eavesdrop on other people's phones, but they are often a scam. After the other party cheated the handling fee, the world evaporated. However, there are still many citizens who worry that this method of copying the SIM card really exists, which will bring hidden dangers to the citizens' communication.
According to the instructions of the technical experts, the reporter tried it and only needed a dedicated card reader and a cracking software to achieve all this. However, when the original card and the copied card are loaded into the mobile phone and turned on at the same time, only one phone can be used normally, that is, copying the SIM card cannot achieve the purpose of eavesdropping. In this regard, the SIM card replication technician explained: "The card that is turned on later will take the network registration right to its mobile phone, and then the card that you turned on before can no longer call and receive text messages. "
It turned out that the background setting of the telecom merchants is to allow only one mobile phone of the same code to access the network. Which mobile phone can successfully access depends entirely on who has a good signal and the last successful access Only that phone can successfully receive calls and text messages, so it is impossible to eavesdrop by copying the SIM card.
However, people in the industry revealed that although eavesdropping is not allowed, if the SIM card of the mobile phone is copied, the mobile phone charges and traffic may be shared. Professionals also put forward their own views on the current security issues of SIM cards: "Compared to the dynamic zone card before 2008, it is still relatively easy to crack, but the SIM cards that are handled in 2009, 10, 11 and later are not easy to crack. It also has its own protection device. Once the number of cracked readings reaches the limit, the mobile phone SIM card will be automatically scrapped. "
