Prepaid subscribers are released

An important reason for the current overflow of spam messages is the lax management of prepaid subscribers by network operators. Mr. Nguyen Van Hung in Viet Tri city, Phu Tho - a person with many years of experience in SIM trading said that SIM traders often import SIMs in batches directly from network operators or buy and sell from SIM traders. Imported SIMs can be unactivated or pre-activated. Although the sale of pre-activated SIMs is prohibited, in reality a large number of activated SIMs are offered every day.

According to regulations, an ID card can only register 3 subscriber numbers, but if only 1 number in the ID card is different, 3 more subscribers can be registered. Those formal regulations have made registering a prepaid subscription extremely simple and uncontrollable. For spam messages advertising beautiful sim numbers, they are usually done randomly, the list for spam messages is purchased from the network operator's staff, so the more postpaid subscribers or beautiful number subscribers, the more likely they are to be spammed with spam messages.

In Hanoi, there are many places selling SIM cards. Network cards are sold from tea shops, grocery stores, to agents. Promotional SIM cards are very cheap, only 30,000 VND - 40,000 VND, especially promotional SIM cards are almost all pre-activated.

An employee who sells SIM cards and collects fees for a network operator in Hanoi said that with current regulations, a person can use many mobile phone numbers. Although the regulation requires a photo ID when registering for a prepaid subscription, it is not easy to find out the subscriber's name because it is also related to the subscriber code. "If you want to use it most comfortably, just buy a junk SIM card on the street, it is cheap and no one cares who you are," said the female SIM card sales employee.

Buying and selling phone numbers is as easy as buying vegetables.

Speaking with Tien Phong reporter, a representative of a department of information and communication affirmed that with the current situation of spam messages, the first benefit is the network operators, then the businesses and individuals who use it to advertise their products and goods.
