Leave messages, ringback music service …
Recently, many mobile phone users have suddenly heard the message “leave a message after a beep” when calling someone. This service allows callers to leave an audio message, and then the message will be converted to text and sent to the listener as an SMS message. Recipients can also call the operator to listen to the voice message again. After leaving a message, the caller will be charged normally. The amount deducted will correspond to the package that customers are using. Even so, many mobile device users don’t know. Ms. Ngoc Thanh (Tan Binh District, Ho Chi Minh City) over the weekend accidentally read the information of many people who shared this service, she was simply shocked because she often left the above message but thought it was free. But now I know that the operator still charges for that message. “After finding out, I asked to cancel the show. Previously, there was a missed call notification service, MCA, if I didn’t sign up, I had it automatically, so even if I didn’t have too much money for each month, I didn’t like it. If a service is needed, I will find out myself to register to use it, without the need for the network operator to program it automatically, ”shared Ms. Thanh.
Not only is the above feature pre-installed, Ms. Yen (District 1, Ho Chi Minh City) is an old lady, she bought it for a Vietnamobile sim to use 3G cheaply. Although this sim does not cost money, you still have to top up VND 50,000 every month to maintain it. It is strange that each time the re-verification is finished, sometimes they can deduct 30,000 VND, sometimes 20,000 VND. Call the switchboard and ask many times to know that there is Uchat (unlimited messaging on the network) and FunVoice (which plays background music on the phone) even if it is not registered. Try to cancel the service syntax, but the next month, it will still be discounted, you have to go to the store a third time to cancel. With the service pre-installed, before that, the phone I was using was also installed 2Funny (entertainment) service and charged weekly without notice …
Lawyer Nguyen Van Duc, director of the Kinh Luan law firm, said he has pre-installed a number of services himself, such as missed call notification, ringback tones and leaving a message after the “beep” sound. However, due to the use of the postpaid service, the operator did not give details of the charges but only indicated the total amount, so it does not know if you will be charged for these services or not. “If it is a predetermined default function for customers, the operator should not charge. For value-added services, it should be clearly notified with specific rates. Customers who need to register will be registered.” service, “said Mr. Duc.
Listening to the call costs more than 200,000 VND
In addition to the services and functions that the network operator silently installs, but users lose money unfairly, phishing calls continue to load silently. Just before the 2.9 ceremony, Mr. Bich (District 3, Ho Chi Minh City) had the entire amount of more than 200,000 VND deducted from his phone bill just after hearing a call from an unknown number. Because he did not pay attention, he saw a phone, Bich was still answering the phone, at the other end was the voice of a woman who wanted to ask for information about the phone number, the user … Mr. Bich replied that he should not turn off the phone. After telling his friend, this person told him to try to check the amount of money on the phone, then Mr. Bich started shooting when his phone bill was less than 10,000 VND. After looking closely, the number displayed is from Uzbekistan. At that time, he recalled less than a month earlier, he also received a call with + 216 (Tunisia) but did not remember how much money they deducted from him.
In fact, fraudulent calls that incur international charges sometimes just hang up or go online, but the duration is very short. Content often requires listeners to call back. Then the caller will be charged all the money in the account because the rate is so high. Network operators have statistics, users can receive missed calls from foreign numbers such as: Modova (+373), Tunisia (+216), Equatorial Guinea (+240), Burkina Faso (+226) … In essence, it is deals with flashing calls from foreign subscribers, including flashing calls from OTT applications to trick customers into calling back and generating unwanted telecom charges. Especially, these calls are often in the afternoon or in the middle of the night when clients are sleepy or think their relatives are calling Vietnam urgently. Also, in fact, starting from common prefixes like 090xxx, 04xxx, 08xxx, the bad guys also make a series of missed calls to mobile subscribers.
There was almost no caution against familiar domestic numbers, so many people called again. At that time, the answering system will prompt them to continue connecting to the 1900 service number with various content, such as wanting to meet beautiful girls or share love problems. Although it may seem a bit suspicious, but out of curiosity, many people still try to follow and as a result, the money in the account without wings flies.
