HÀ NỘI – Congratulation! You are this week’s winner. Send DKG to 9183 to receive a top-up card worth VNĐ200,000 (US$8.56).

This is just one of the many text messages that pop up on the phone screen of Minh Hương in Hoàn Kiếm District every day.

These advertisements encourage users to try multiple services, from data packages to top-up cards, and from English courses to new real estate projects in town.

“It’s totally insane,” Hương told Việt Nam News.

“They (the network providers) promised to start blocking all spam calls and messages from 2017, but nothing seems to have changed,” she added.

Hương has two phone numbers with the biggest network providers in the country, Vinaphone and Viettel.

While spam from Viettel invite her to join Keeng, a music social network, watch movies online or use a new mobile money application, Vinaphone advertises data packages, quiz games (which promise rewards far bigger than the cost of a text message) and a variety of promotions.

“It’s funny that most of the messages are sent by the telecommunications providers themselves. If you want to stop receiving the messages, you have to send a message to unsubscribe from services you never registered for,” she said.

“It’s just ridiculous,” Hương said.

Spam messages, unfortunately, are not the only nightmare.

Thu Vân in Hai Bà Trưng District is pestered by many spam calls every day.

“It’s crazy how much they seem to know about their target audiences,” Vân said.

“They know where I live, how old my children are, and offer exactly what a person like me will need or consider,” she added.

Vân presumed that her personal information had been traded from other organisations.

“I try to be patient, but sometimes when we are busy or the calls come early in the morning, I get so annoyed. I react angrily, and they criticise me for being impolite,” Vân said.

Most of the people interviewed said that spam calls were more irritating than messages because they didn’t know where they were coming from until they answered.

“They can attack you at anytime, when you are sleeping or working,” complained Quốc Tuấn from Hoàn Kiếm District.

Tuấn said all he could do was block the numbers or not pick up from unknown callers.

“I don’t know where they got my phone number from. It is obviously illegal for my personal information to be traded by other people. However, I have no idea how law enforcement can deal with this type of crime,” he said.

According to Vũ Ngọc Sơn, deputy head of Bkav Corporation, despite blocking software, it was impossible to prevent all spam calls and messages as they did not know how many phone numbers were being used for advertising purposes. 

Instead of using preactivated sim cards, companies have switched to using registered numbers for telesales, making it difficult to tell whether an incoming call is spam or not.

“Customers do care if those numbers are registered. They consider it spam and feel harassed. At present, there is no potential solution due to the conflict between providers and customers,” Sơn told Thanh Niên (Young People) newspaper.

Sharing the opinion, Võ Đỗ Thắng, director of Athena Cyber Management and Security Training Centre, said that telecommunications providers had to proactively prevent spam because not many people had efficient blocking software on their phones.

“We will have to tolerate this problem until strict regulations are applied,” Thắng said.

According to the Việt Nam Telecommunications Agency, in 2017, providers deactivated and withdrew 24 million pre-activated SIM cards to reduce spam calls and messages.

From May 2017 to March 2018, 260 million spam messages were blocked. The Computer Emergency Response Center (dial 456) is in charge of receiving and recording spam messages, but is unable to stop spam calls. — VNS
