This is considered a very strong step to protect service users themselves, and at the same time contribute to cleaning up the telecommunications market, eliminating junk SIMs, non-genuine SIMs and limiting spam calls, spam messages, and phone scams.
According to the Telecommunications Authority (Ministry of Science and Technology), the reality over the past time shows that many mobile subscribers, although they have fully registered information, users are not their own owners. There are cases where people's personal information is illegally used to register SIM cards, then sold to others. There are also cases where users once registered SIM cards, then abandoned them but forgot to cancel the service.
Although management agencies and network operators have repeatedly launched campaigns to standardize subscriber information, the situation of non-genuine SIMs and junk SIMs still cannot be thoroughly handled, thereby leading to fraudulent activities continuing to become complicated. One of the reasons is that the biometric authentication process used to be mainly performed once when registering a new SIM, then there was almost no re-verification mechanism throughout the usage process.
This is a loophole that in many cases, SIMs that have been fully verified continue to be transferred to fraudsters or illegal organizations that management agencies find very difficult to detect.
The need to authenticate when changing phones is a solution that hits one of the most important links in SIM card trading after authentication. This also requires a synchronous process between management agencies, telecommunications businesses and service users. In which, biometric authentication when changing end-to-end devices is an important step to close the loophole of non-genuine SIM cards.
When each phone number is attached to the actual user, junk SIM cards are easily removed, junk calls, spam messages and phone scams will be narrowed in "land to live".
A clean telecommunications market both requires technology and requires responsibility. The responsibility of network operators in subscriber management; the responsibility of functional agencies in monitoring and protecting personal data and the responsibility of each user in using and managing their own phone numbers correctly. From there, the telecommunications market will be more transparent and "cleaner".
