In recent years, Vietnam has recorded increasing numbers of fake calls and spam calls. In particular, a new form of automatic advertising call (robocall) has appeared, affecting social order and people's interests.
In July 2020, the Ministry of Information and Communications asked network operators to take measures to prevent fake and spam calls based on the provisions of the Law on Protection of Consumer Rights and Decree No. 91/2020/ND-CP of the Prime Minister. By the end of June 2021, local network operators blocked more than 181,000 subscribers from spreading spam calls.
The number of people's complaints about spam calls over the number 5656 has increased by an average of 13-15%/month. This shows people's interest and response to measures to prevent spam calls.
A representative of the Department of Telecommunications said that the number of spam calls and the number of affected subscribers has decreased significantly. In June 2021, there were about 8.4 million spam calls, down 31.9% compared to December 2020 with more than 5.4 million subscribers affected, down 23.5% compared to December 2020.
The Department of Telecommunications has instructed network operators to build a system to detect and prevent fake calls. By the end of June 2021, Vietnamese telecom service providers prevented more than 56.65 million fake calls.
