Deadline for subscriber verification to avoid having your SIM card blocked or your number revoked.

According to Circular 08/2026/TT-BKHCN, the deadline for people to verify their subscriber information is running out. In accordance with the circular, the one-way blocking of calls and messages has been in effect since the beginning of May, and will soon be extended to two-way blocking and number revocation for subscribers who do not verify their subscriber information.

With their SIM cards blocked for outgoing calls, people are rushing to verify their accounts.

In recent days, at many mobile network service points in Hanoi , Ho Chi Minh City, and other localities, people have been updating their subscriber information. In fact, it only takes a few minutes or a quick lunch break to visit the network's support points to complete the subscriber verification process very quickly.

At a Viettel transaction point in Hanoi, Ms. Linh, a customer who came to verify her SIM card, recounted that when she realized she couldn't make calls as usual, she suddenly remembered that she hadn't verified her subscription. "I received a notification message from the network provider, but I forgot because I was busy with work. This morning, when I couldn't make calls, I remembered and had to come verify it right away," Ms. Linh said.

At another Viettel transaction point, Ms. Hien, 61 years old, said that she had previously received numerous text messages reminding her to verify her information but hadn't paid attention because she thought the procedure was complicated. Only when she heard the announcement that her SIM card was at risk of being blocked did she rush to the nearest store to complete the procedure. "Initially, I thought I would have to wait a long time, but the staff guided me quite quickly. It only took a little time queuing, and the update probably took less than 3 minutes," she shared.

For those who are unable to go to the service center themselves due to old age or poor health, the network provider has also provided the best possible solution. Ms. Lan, residing in Giang Vo ward, Hanoi, said that her mother's phone number had been blocked for several days, making communication very inconvenient. However, due to her busy schedule and her mother's advanced age, she couldn't arrange to go to the service center to complete the procedures. Seeing that the network provider was implementing a home verification program, she called the hotline 18008098, pressed 0 to schedule an appointment, and a network employee came to her home to assist her.

Viettel assists customers in quickly updating and verifying their subscriber information.

Many subscribers are about to have their SIM cards blocked for both incoming and outgoing calls, and their phone numbers revoked.

According to Circular 08/2026/TT-BKHCN, effective from April 15, 2026, subscribers who have not completed information verification and biometric testing will be processed according to a specific schedule, ranging from blocking incoming calls and messages to blocking both incoming and outgoing calls, and finally, revoking their phone number.

According to statistics from the management agency, there are still tens of millions of subscribers whose identities have not been verified on the VneID system, and more than 1 million phone numbers have been confirmed by people as no longer in use.

Mobile network operators say the groups most at risk of having their SIM cards blocked currently include: subscribers who have not verified their biometric data; SIM cards registered under someone else's name; subscribers using old or inaccurate identification documents; elderly users unfamiliar with technology; and people in remote areas with limited access to services.

Sprint to the finish line: Mobile network operators extend service hours until 9 PM, provide in-home support for the elderly.

Currently, telecommunications companies are expanding both in-person and online support. Viettel Telecom alone reports having deployed nearly 50,000 support points nationwide, ranging from official stores and affiliated agents to mobile support points in communes, wards, and residential areas. Furthermore, many service points now extend their operating hours until 9 PM to assist people after work. Some locations even send staff to local areas to support the elderly or residents in remote areas.

Specifically, starting May 21, 2026, Viettel Telecom announced the implementation of a home-based subscriber verification program for elderly and infirm customers. To receive this service, customers simply need to call the Viettel Customer Care Hotline at 18008098 (toll-free). Then press 0 to speak directly with a customer service representative and provide the necessary information such as full name, phone number, and address. Viettel staff in the area will contact you directly and come to your location to assist in completing all procedures safely and thoughtfully.

Viettel staff assist elderly customers in completing the subscriber verification process.

This solution is considered the most drastic, aiming to help the elderly and those with health problems (who currently account for up to 30% of unverified subscribers) easily complete the procedure without having to travel far.

Besides the in-person method, users can self-verify at home through the My Viettel, Viettel Tammi, or VNeID applications using a level 2 identification account. The verification steps include: Logging into the application using the phone number to be verified - Taking photos of both sides of the Citizen Identification Card (CCCD) and a portrait photo - Scanning the chip-embedded CCCD via NFC; face matching - Checking information, viewing contracts, and electronically signing - Entering the OTP code to confirm successful verification.

Additionally, people can check their subscription status by sending a text message: TTTB [space] ID card number to 1414

Amidst the increased demand for authentication, mobile network operators are simultaneously issuing warnings about the risk of fraud. Recently, there have been many calls from individuals impersonating telecommunications employees, requesting users to provide OTPs, download unfamiliar applications, or access fake links to "standardize their SIM cards."

Experts advise people to absolutely: not provide OTP codes to anyone; not click on strange links; not send photos of their citizen identification cards through unofficial platforms; and only verify identity through the official application, website, or transaction points of the network provider.
