Many people wonder how they are safe when things like these happen and what number they need to take care of. The problem is that the number differs every time, as scammers can use so many fake-calls applications. That is why law enforcement recommends people use phone number checking programs to keep their data safe and their money in their pockets. The best way to protect yourself from vishing is to be vigilant about missed calls from unknown numbers or places outside the country where you do not know anybody.
