According to the plan of the Telecommunications Department, Ministry of Information and Communications , from March 15th, network operators will invite customers to update/standardize information for subscribers whose details do not match the national population database.
However, shortly after the network provider implemented the plan, many users received calls and messages from impersonators threatening to "block their subscriptions."
Specifically, users will receive a call informing them that their subscription is about to be blocked, and then requesting them to follow certain steps. At this point, the scammers, posing as network employees, ask users to provide their national identity card or citizen identification number to check if the subscription is registered under their name.
If users refuse to provide the information, the perpetrators make threats about their subscription being blocked and demand that users follow instructions. At this point, if users follow the instructions, they risk losing control of their SIM card, and the attackers will proceed to steal other accounts such as bank OTP codes, social media accounts, etc.
In light of this situation, MobiFone advises that the standardization process does not require any information related to bank accounts, and customers should absolutely not perform any operations related to money transfers or bank account logins. The subscriber information standardization process is completely free of charge.
Customers should only receive information and follow instructions when they receive official messages from the MobiFone brand name or calls from the 9090 number.
Here's a sample message from MobiFone inviting customers to update their subscriber information:
"In accordance with state regulations, the personal information of the customer registered for the phone number XXXXXXXXX does not match the national population database."
Please update your subscriber information using your citizen ID card at a MobiFone store or via the My MobiFone app https://api.mobifone.vn/apps/download/ or the website https://tttb.mobifone.vn/.
Your subscription will be blocked in one direction on dd/mm/yyyy if you do not update your information. If you do not update within the next 15 days, your subscription will be blocked in both directions according to Decree 49/2017/ND-CP. Please ignore this message if you have already updated your personal information. For details, please contact 18001090/9090.”
4 ways to standardize subscriber information:
Option 1: Go to the nearest MobiFone store.
Method 2: Via the website https://tttb.mobifone.vn/ (applicable to individual customers and users within organizations and businesses).
Method 3: Via the My MobiFone app (for individual prepaid customers whose numbers are not duplicated in the national population database).
Option 4: We will provide in-home support for clients with specific needs, such as the elderly.
