The reduction in the turnover of grey SIM cards is a consequence of tightening legislation: first of all, this is due to the fact that operators are required to verify users of already purchased and used SIM cards, noted the head of the Content-Review project, Sergei Polovnikov. In addition, communications providers have tightened their internal practices: limits have been introduced on the issue of cards to the same dealer, and retail sales are also restricted in suspicious cases, he added.
At the same time, the algeria whatsapp number database expert believes that the problem of the existence of gray goods is that mobile operators cannot control all their dealers: telecom operators provide SIM cards to sellers, and in return they provide the passport data of subscribers, which is extremely difficult to double-check. According to him, these cards then appear in the hands of fraudsters, spammers, in black contact centers, on bot farms. Therefore, the seizure of such media before they are used is an absolutely correct and necessary practice, the expert believes.
— The numbers used by the attackers end up on all sorts of blacklists. After they are no longer used, they return to the operator pool, and then they are sold again to unsuspecting citizens. And with such a exposed number, it is impossible to register in Telegram, you can’t call many places, and so on, — said Sergey Polovnikov.
This could soon lead to a shortage of clean rooms, he believes.
“Grey SIM cards appear thanks to unscrupulous dealers and sub-dealers,” agrees TelecomDaily CEO Denis Kuskov.
In his opinion, the problem could be solved by banning the sale of SIM cards anywhere except in communication stores and large retail chains. If such points of sale are not available in a locality, the practice of self-registration of users using remote technologies should be developed, the expert concluded.
