The Ministry of Public Information issued a document reminding users to be wary of "text message fraud that pretends to copy mobile phone SIM cards". Is this the case?

There is a way to copy mobile phone cards. I have also copied it, but you must get the original card to copy it. It is not a waste of time as scammers say, just make a phone call. I copied someone else's SIM card.

Moreover, the copied card can only be used to make and receive calls: only one card can be used. When two cards are turned on at the same time, only the last one turned on can be used, and the other one will not ring. , and cannot be used for eavesdropping.

Fraud method:

Get a number A from your hand that you want to eavesdrop on. After a while, use software to change the caller number and call you in the name of number A. The phone call says that the card has been made. You can pay and get the card. Because you think it is the call from number A, it makes you feel that it is copied. If I have this card, I can simultaneously eavesdrop on the phone owner’s phone calls and text messages. . So I paid and got scammed.

In fact, he committed fraud in the name of copying SIM cards and had nothing to do with the work of copying cards.
