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

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

In recent days, at many service points of mobile network operators nationwide, including Nghe An, people have been updating their subscriber information. In fact, it only takes a few minutes or a quick lunch break to visit the network operator's support points to complete the subscriber verification process very quickly.

At a Viettel transaction point in Thanh Vinh ward, Ms. Huong, a customer who came to verify her SIM card, said that when she realized she couldn't make calls as usual, she suddenly remembered that she hadn't verified her subscriber account. "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. Huong shared.

At another Viettel transaction point, Ms. Loan (64 years old) said that she had previously received numerous 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 cases where people 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. Le Thi Tam from Kim Lien commune, Nghe An province, said that her mother's phone number had been blocked for several days, making communication very inconvenient. However, due to her busy work schedule and her mother's advanced age, she had been unable to arrange a visit to the service center. 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 house to assist her.

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.

According to mobile network operators, 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: NThe network extends its service hours until 9 PM., home support for the elderly

Currently, telecommunications companies are expanding both in-person and online support. Viettel Telecom alone reports that it has 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 an operator 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.

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), taking a portrait photo, scanning the chip-embedded CCCD via NFC; comparing faces to verify information, viewing the contract, electronically signing, and 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: Do not provide OTP codes to anyone; do not click on strange links; do not send photos of their citizen identification cards through unofficial platforms; only perform authentication through the official application, website, or transaction points of the network provider.
