Startled at first, users gradually find ways to handle it
In recent days, when notifications about subscriber authentication have appeared a lot, many users have proactively checked their personal information. However, each case is different, so many concerns arise.
Ms. Nguyen Thi Van (Hung Yen), using a phone number for more than 7 years, initially worried about having to redo the procedures. After checking on the application and seeing that the information matched, no need for further verification, she was reassured.
Meanwhile, Mr. Tran Quang Minh (Hai Phong) encountered a different situation when using two phone numbers simultaneously for work and personal purposes. Learning about the regulations, he learned that each subscriber must be verified separately. "Initially, I thought I only needed to verify the main number. When checking on the application, I learned that each number must be done separately, it is very easy to be mistaken if you do not pay attention" - Mr. Minh said.
According to him, operating on the application is not complicated, but users lack guidance according to each specific case, so they are still confused.
A more complicated case is that SIM card users buy them back many years ago. Mr. Pham Quoc Hoang (Hanoi) informed that he bought a beautiful number nearly 500 million VND 5 years ago, but is worried when verifying because he can no longer contact the old owner.
After arriving at the transaction point, he was instructed to standardize subscriber information to the correct subject before biometric authentication. Although taking more time, he said he was more reassured when his phone number was already in his name.
According to records, initial confusion does not stem from difficult operations but because users do not know which group they belong to and what to do. When accessing the correct information, most can complete the process.
Regulations are clarified, network operators guide according to each situation
Regulations in Circular 08/2026 issued by the Ministry of Science and Technology, mobile subscriber authentication is carried out on the basis of comparing personal information with the national population database. In which, 4 mandatory information fields must match, including personal identification number, full name, date of birth and facial image.
This regulation is applied in cases such as new subscriber registration, information updates, or when changes arise during use, including switching SIMs to other devices. For subscribers who have not completed authentication or have unsynchronized information, services may be restricted according to the roadmap. On that basis, telecommunications businesses have implemented solutions to support users in implementing authentication.
According to Viettel Telecom, the subscriber authentication feature has been integrated on the My Viettel application, allowing users to perform it at home with citizen identification cards, reducing dependence on transaction points. Similarly, VinaPhone and MobiFone also added authentication utilities on the application, helping users flexibly choose the appropriate form.
Talking to Lao Dong Newspaper, Lawyer Nguyen Van Phi - Deputy Director of Law Firm Lawkey - said that from April 15, 2026, mobile subscribers who have not completed verification or have information that does not match the national population database may be restricted from services according to regulations. However, according to regulations, not all subscribers must re-verify immediately. For those numbers that have been standardized and have no data errors, users only need to check when there is a notification from the system.
Notably, from June 15, 2026, when the SIM is used on another device, the system will require re-verification of the face within a certain period of time. If not completed, the subscriber may have their call delayed. For arising cases such as using multiple subscribers or SIMs in the name of organizations, each number must still be verified separately according to the actual user information.
Regarding cases of SIM cards being bought or no longer being able to contact the old owner, Mr. Nguyen Van Phi said that users need to carry out procedures to update subscriber information to the correct owner before proceeding with verification.
If the subscriber information does not match the user, verification will not be complete. Therefore, it is necessary to convert the owner's information first, and then carry out biometric verification" - Mr. Phi said.
The lawyer recommends that, for arising cases, users should go to the official transaction point of the network operator to receive full and accurate support.
Subscriber authentication is a necessary step to ensure that each phone number is assigned to the right user. When the process is clear and implemented synchronously, users can proactively implement it without encountering many obstacles.
