Out of 1.15 million two-way lock subscribers, 985,000 subscribers had their numbers revoked and contracts were liquidated today due to non-standardization of information. Mr. Nguyen Phong Nha, Deputy Director of the Department of Telecommunications – Ministry of Information and Communications, said that as of this afternoon, telecommunications businesses have withdrawn and canceled more than a million subscribers. These are phone numbers that do not update their information to match the national population database, so their contracts are terminated under Decree 49 on mobile telecommunications. According to Mr. Nha, since the two-way lockdown on April 15, less than 15% of the 1.15 million subscribers have standardized to be unlocked again. According to Decree 49, phone numbers with non-standard information that do not match the national database will receive a notification from the network operator. Subscribers are stopped from providing one-way telecommunications services if they do not do so after 15 days of notice, and two-way stop if they do not do so after the next 15 days. One month later, the subscriber number will be revoked and the telecommunications enterprise will provide it to other individuals and organizations in need. Statistics show that by the end of 2022, Vietnam has about 127 million subscribers, focusing on three main carriers: Viettel, MobiFone, and VinaPhone. By mid-March, carriers said about 3.84 million subscribers had not standardized their information. The standardization is one of the activities to implement the Government’s Project 06 on “Developing the application of population data, identification and electronic authentication for national digital transformation in the period 2022-2025, vision to 2030”. This activity is considered necessary in order to handle the act of using phone sims in contravention of regulations to deceive and advertise falsely. The use of an unauthorized sim to call and text is also one of the causes of spam calls and messages. In addition, according to carriers, accurate subscriber information will help users be better supported in online public services, and at the same time reduce the risk of information being used for malicious purposes. After the standardization phase of subscriber information, the Ministry of Information and Communications said that it will conduct a check on the status of using non-original sim cards, especially individuals and organizations that register multiple sims, leading to the risk of sim is used for malicious purposes. In a press conference in early May, Director of Telecommunications Nguyen Thanh Phuc said that the ministry will organize a large-scale inspection with the participation of the Departments of Information and Communications of provinces and cities to handle unregistered sim cards right in the month. 5 and 6.
