number 3649

It is to this number that a SMS is sent to send a virus that blocks Windows and that has been written on the Habrr more than once:

I googled a bit and saw that the number of such exists for a long time and it is used by many sms-services of a divorce for money. In Megaphone they said that the cost of SMS will be 177 rubles, and the number itself belongs to the First alternative content provider. How would you reach the operators so that they block this number and subsequently block all such numbers? Operators profitable, they share, but this is complicity in fraud!
