Shi Jinyu didn't answer Zhou Jielin's words, but asked Guan Nuo: "It's been so long, have you found the person who asked for a lawyer?" ”

Guan Nuo shook his head and said, "This is the strangest place, the phone left by this person is a black card without a real name system, and it is also a kind of space card." ”

"Isn't the space card only available in Hong Kong dramas?" Perimeter Lin said in surprise.

"The space card was called by Hong Kong people, and it is more thief, so it uses the same shell, Bilibiliha?"

"Recording line, you know this for a while, right?

Guan Nuobian fiddled with the computer and said: "The space card is a SIM card, but it does not have a real-name system, the card refers to the customer identification module, also known as the user identification card, smart card, G** digital mobile phone must be installed with this card to use." The computer chip stores the information of the digital mobile phone customer, the encrypted key and the user's phone book, etc., which can be used for the identification of the customer of the G** network, and the voice information of the customer when the customer is talking is encrypted.

From September 1, 2015, all kinds of physical marketing channels of telecommunications enterprises will be fully equipped with second-generation ID card identification equipment, and when users go through the network access procedures, they must verify the user's resident identity document by using the second-generation ID card identification device, and automatically enter the user's identity information through the system. The original intention of implementing the real-name system is to curb the spread of bad information, prevent and crack down on all kinds of telephone fraud activities, and solve the problems of difficulty in obtaining evidence and investigating and dealing with relevant departments.

In order to comprehensively promote the supplementary registration of old users who have not yet registered their real names, telecommunications enterprises shall require the old users who have not registered their real names before September 1, 2013 when they handle new services and replace their mobile phone cards, so as to ensure that by December 30, 2015, the real-name registration rate of all telephone users of the enterprise will reach 90 percent, as before the date.

China Telecom, China Unicom, and China Mobile said that non-real-name mobile phone numbers may be shut down. When registering under the real-name system, you must be present in person with your ID card. But in fact, there are also black cards. ”

"Even if it's so strict, there is a black card?" Liang Yien asked incredulously.

"Of course." Guan Nuo nodded and said: "Usually, if you don't want to get an ID card, it's usually 30 yuan a piece, including 10 yuan for phone bills, a call, and a minute for a dime." This kind of temporary use, after buying it, you don't call, it will shut you down, you harass people's text messages, phone calls, people may also give you downtime. That's pretty good, but the scariest thing is the kind that has already been registered. So the price is super cheap.

At a price of 25 yuan, you can successfully buy a mobile phone card with a section 171. This kind of mobile phone card has been authenticated with someone else's identity, so you can use it with confidence and are not afraid of downtime. In other stalls, some shopping websites, and second-hand trading websites, there are also people selling mobile phone cards that do not require identity authentication or have been verified by real name. Although some websites indicate that proof of identity is required to purchase a card, when we inquire further, the merchant promises that the seller can verify the activation number without providing an ID card, and said that the mobile phone number can be used all the time when there is a phone bill.

The 171 mobile phone card is put into the mobile phone, except that there is no 4G signal, the card's functions such as making and receiving calls, sending and receiving text messages, and surfing the Internet are basically the same as those of other mobile phone cards. The relevant customer service staff said that there were a group of agents when the card was launched in the early stage, because at that time, an ID card could open five cards, and card dealers used ID cards to open a large number of cards and stock up goods, and then changed hands to increase the price for a second sale, and the price generally ranged from 25 to 50 yuan. ”

"Then all the people in section 171 are liars?" Xu Jiuyan asked.

Guan Nuo shook his head and said, "Not only. The mobile phone numbers in sections 170 and 171 refer to virtual operators renting the networks of the three traditional operators, and then selling communication services to consumers through their own billing systems, customer service numbers and management systems. A series of number segments represented by 170 are from the exclusive number segments issued by virtual operators. In order to save costs, some virtual operators require all mobile phone numbers to be real-name in order to save costs. When fraudsters use these numbers to commit fraud, they can go incognito, and the cost of breaking the law is greatly reduced.

However, due to the implementation of the real-name system, virtual operators have to invest a lot of costs, for example, it costs at least 1,000 yuan to equip a machine with an ID card recognition, and each time a user identity is authenticated, they also need to pay a fee, which is almost one dollar per user. With these considerations, it is not difficult to understand that virtual operators have problems when implementing a non-real-name system. Some virtual operators rely heavily on agents to distribute mobile phone cards, and the supervision link is weak, resulting in the implementation of the real-name system in place. ”

As a technical controller, Guan Nuo is always sensitive to numbers, saying: "According to relevant reports, from November 2015 to the end of April 2016, the Ministry of Industry and Information Technology has organized telecommunications companies to quickly shut down more than 100,000 phone numbers involved in communication information fraud and other crimes, including more than 60,000 virtual operator numbers, and the numbers involved in the shutdown involving virtual operators are distributed in more than 20 companies such as Yuantel Communications, Share Communications, Dixintong, Snail Mobile, Bus Online, Gome Mobile, Tianyin Communication, and Aisid. And this number is issued by the company Else.

In April this year, the Ministry of Industry and Information Technology urgently interviewed some virtual operators whose real-name system was not in place, and at the same time issued the "Notice on Strengthening Standardized Management to Promote the Healthy Development of Mobile Communications Resale Business", requiring virtual operators to complete the supplementary registration of user identity information within one month for phone numbers that have not been registered with real names or falsely registered in the early stage. However, nearly 4 months have passed, and non-real-name calling cards are still "doing their own thing". So there is a sentence that can sum up this, out of a hundred "170" numbers, ninety-nine are used for fraud. ”

Guan Nuo also called up the police's case analysis database, saying: "The frequent occurrence of telecom fraud and unpreventable spam text messages have brought the 170 and 171 sections into notoriety. According to the investigation of CCTV reporters, 170 and 171 fraud accounted for nearly half of the total number segment, and due to the lack of implementation of the real-name system, it was very difficult to crack the fraud case. From last year to this year, more than 99 percent of the No. 170 and 171 sections that flowed into Nanyi City were used for fraud and illegal activities. This year, there have been more than 800 fraud cases involving Section 170 in Nanyi City, and citizens have been defrauded of more than 11 million yuan. And there are countless people who have violated the law through these two number segments, and I believe that this person is also like this. ”

Shi Jinyu nodded and said: "That's right, this person also chose such a number after feeling this point, and now the situation is complicated, this person must be found, because he will be the key to solving the case." ”
