HÀ NỘI — Mobile phone subscribers with personal information that does not match the national population database will be blocked from March 31.

Nguyễn Phong Nhã, deputy director of the Department of Telecommunications under the Ministry of Information and Communications, said the standardisation of information is carried out following Decree 49 on mobile telecommunications.

Phone numbers with incorrect information will receive a notification from the mobile carriers.

Mobile phone providers will send messages to customers for five days at least once a day to ask subscribers to update their information as requested.

The providers will block incoming calls 15 days after the first notification is sent out, while the two-direction block would take effect after the following 15 days if the subscriber still fails to update their personal information with the carriers.

After 60 days from the first notification, uncooperative subscribers would have their contracts terminated.

The notifications will be launched from March 15, Nhã said at a meeting on information standardisation of mobile phone subscribers on Monday.

The Department of Telecommunications also asked customers to coordinate with mobile service providers to update their information, avoiding impersonation to perform illegal acts.

The agency also said it is still very difficult to wipe out junk SIM cards.

According to reports from major mobile phone providers – MobiFone, VinaPhone, and Viettel, there are about 3.5 million mobile subscribers whose information does not match the national population database.

According to Decree 49, all mobile subscriptions need to provide accurate personal information of owners, including name, identification number and profile picture.

The regulation aims to help protect the interests of customers using the service and limit the number of junk SIMs in the market.

In 2022, the Government ordered that every active mobile phone number must be linked to the national population database. — VNS
