Now, when the messenger discovers such cases (fears) he blocks the account and does not allow the fraud to continue with this phone number any activity of the messenger to demonstrate. But we need to block it at the level of telecom operators. And not only, perhaps, this SIM card, but also all SIM cards belonging to this owner, said the head of the office Maksut Shadayev on Thursday at the Kazan forum. "That is, if we have detected a fraudulent SIM card, then the SIM card itself must be blocked and perhaps even a cooling-off period should be introduced when that person cannot issue new SIM cards. " And that is exactly what our sovereign platform (the national envoy Max) gives us, the minister added. The head of technology holding VK, developed Max, Vladimir Kirinko said that during the year of the national messenger blocked more than 4.5 million fraudulent accounts. @interfaxonline.
