Why does the garbage sim still not run out of spam calls?

Junk sims have not been thoroughly cleaned, while bot services and OTT applications explode, causing users to still be bothered by fraudulent calls and advertisements. Thu Thao, 25 years old in Dong Nai, was one of the first to actively go to the network operator’s transaction office to (standardize subscribers)(https://vnexpress.net/so-hoa/hang-tram-nghin) -nguoi-di-chuan-hoa-thue-bao-4582030.html) in March, after receiving a series of fake calls every day. However, when 1.5 million sims were locked one-way on March 31, Thao continued to be harassed by spam calls, most of which had fraudulent purposes, with a frequency that did not decrease. Thao is no exception. (Survey)(https://vnexpress.net/vi-sao-chua-het-sim-rac-4589891.html) of *VnExpress* in early April showed that 68% of the total more than 4.7 thousand participants Gia says regularly receive (spam calls)(https://vnexpress.net/so-hoa/bi-xuc-pham-de-doa-khi-hear-cuoc-goi-rac-4625723.html) and only 4% are no longer bothered. According to the report of the first 6 months of the year of the Information Security Department – Ministry of Information and Communications, two portals *chongthurac.vn* and *thongbaorac.ais.gov.vn *received hundreds of thousands of complaints from people about spam calls*. *The number of cases (online fraud) (https://vnexpress.net/so-hoa/nguyen-nhan-lua-dao-online-tang-manh-4625939.html) increased 64.78% over the same period last year Last year and increased by 37.82% compared to the last 6 months of 2022. **Spam sim cards have not been thoroughly processed** A representative of a network operator said: “Users are still bothered by spam calls because of the standardization of subscribers. (https://vnexpress.net/so-hoa/tran-lan-sim-rac-4580882.html) Many junk sims are pre-activated with other people’s information. and standard, which matches the national population data, so it can still be used normally.” He said that even if the owner’s sim card is tightened, spam calls will still be raging. As a rule, each person can register up to three official sim cards on a telecommunications network. With five carriers, an average person can register 15 numbers. A company specializing in providing customer service by phone with 100 employees has 1,500 numbers to “bomb” users. Not to mention, many parties still look for “standardized garbage sims” that are bought and sold on the “black market”. According to the Ministry of Information and Communications, over the past time, buying and selling of garbage sim cards is still common. This led to an outbreak of harassing calls, debt collection terrorism, fraud, insults, social disorder and safety, causing many people to suffer property damage. Mr. Nguyen Thanh Phuc, Director of the Department of Telecommunications – Ministry of Information and Communications, said that after standardizing subscribers, authorities began to check individuals and organizations owning many sim cards. By 7/7, telecommunications businesses have finished processing subscriber files that are corporate customers who own more than 10 sim cards. It is expected that by July 25, individual customers with more than 10 sim cards will be processed. From the end of 2022, the Ministry of Information and Communications announced three major stages in dealing with garbage sims. First, make sure all subscribers have the information. Next, ensure accurate information by checking with the National Population Database. Finally, handle the status of the sim card is not genuine. Up to now, the network operator has completed two stages. The last step is to make sure the subscriber uses the original sim card. “When everyone is using a genuine sim, from the subscriber number can look up personal information and vice versa. This helps detect and handle organizations and individuals using the sim to commit violations and cause harm. bad effects on society”, said a representative of the Ministry in April. **Other sources of spam calls** According to Mr. Vu Ngoc Son, Technology Director of NCS Cybersecurity Company, spam calls are not only is done via phone sim but also distributed from many forms such as switchboard registered with network operators, OTP application. Recently, automated software on the computer (auto bot) has also proliferated, automatically calling and playing recorded content to customers. Some automated calling tools like PhoneBurner allow the machine to make calls from the input list regardless of day and night, leaving users in a state of receiving one after another. Some also take advantage of this tool to “terrorize” others or serve fraudulent purposes. Fraud groups are also switching to OTT platforms instead of calls from traditional digital sims. “OTT services that allow buying and selling accounts and making calls are no different from regular calls but are not subject to the management and supervision of carriers in Vietnam. Currently, there are no specific regulations and sanctions to handle these groups,” said Mr. Son. Therefore, according to Mr. Son, the handling of garbage sim cards cannot “erase” spam calls. **How ​​to deal with spam calls** Constantly attacked by spam calls, many people choose to block numbers. Reader Phuc Long said: “Just pick up the phone, say a few sentences, I can identify the spam call. Up to now, my block list has reached more than 200 numbers, it took a bit of work at first, but the effect is obvious, the frequency is clear. The number of annoying calls has been reduced. ” However, there are also people who say the block list is “long but still annoying, it doesn’t work because it’s a different number every time”. Another common way to deal with this is to install an application to filter calls and spam messages such as TrueCaller, Hiya, VeroSMS. In which, (TrueCaller)(https://vnexpress.net/so-hoa/truecaller-them-tinh-nang-ghi-am-cuoc-goi-cho-iphone-4617631.html), is used by many users in Vietnam Nam chooses because it can be used on both iPhone and Android, the data source from the community is quite rich, so it is effective in identifying calls to offer services and scams. The Information Security Administration also implemented a non-advertising list (DNC) management system. Users can text DK DNC to 5656 or visit the website *khongquangcao.ais.gov.vn *to be included in the list of not receiving ads. Numbers blocked through the Bureau’s system have been verified and should work correctly. However, according to Mr. Son, in fact, soliciting and fraudulent calls are now constantly being changed, so the omission is quite large. In the first quarter of 2023 global call threat report, Hiya, the anti-phishing app developer, said: “No country in the world is immune to spam calls. One in four calls from unknown person, there was an advertising or scam call. In the first three months of 2023 alone, there were about 6.7 billion spam calls globally, or 73 million calls per day.” Meanwhile, the US Federal Communications Commission (FCC) says spam calls are the most common problem that users complain about. The agency is looking for ways to prevent illegal calls, but even strict regulations in the Telephone Consumer Protection Act (TCPA) do not address spam calls.
