What are carriers doing to limit junk SIMs?

(Dan Tri) - For many years, junk SIM cards have become a tool causing an outbreak of harassing and fraudulent calls, causing disorder and disruption to social security.

Up to now, the above problem has not been completely resolved because junk SIM cards are still being sold everywhere for only a few tens of thousands of Dong.

Speaking with Dan Tri reporter, a representative of a network operator said that to limit junk SIMs and non-owner SIMs, all points of sale must use specialized tools of the business and comply with regulations to ensure that newly activated subscribers have full information according to the law.

"The network operator also checks documents with the population database, performs eKYC extraction of customer document information to prevent forgery, and makes video calls to identify real people," he shared.

Network representatives also said that telecommunications businesses are actively coordinating with the Ministry of Public Security and the Ministry of Science and Technology to find the best customer identification solutions.

In 2023, the authorities requested network operators to standardize subscriber information to remove junk SIMs and unregistered SIMs from the system. After a large-scale crackdown, a total of 19.6 million subscribers with inconsistent information were processed.

However, the problem of spam calls still haunts mobile users in Vietnam. Up to now, many people said they are constantly bothered by unwanted calls with the content of loan solicitation, brokerage, product introduction, or even fraud.

According to many experts, junk SIMs often have a much larger number of messages and calls than normal SIMs. Some SIMs even send hundreds of messages and make dozens of calls every day.

This means that junk SIMs also generate revenue for network operators. Therefore, the responsibility for junk SIMs - one of the main means used in marketing calls, scam calls and advertising messages - lies primarily with network operators.

Mr. Do Van Thinh, Director of CMC Cyber ​​Security Operations Center (CMC Cyber ​​Security Company, CMC Technology Group), said: "For silent calls, the main goal of these subjects is to confirm the status and classification of the data they have obtained.

Users receiving strange phone calls but not saying anything is a way for subjects to filter user data, sell data or create suitable scam scenarios.
