It is very likely that behind the phone calls that are hung up, do not answer or are pre-recorded, malicious people are hiding trying to steal information, scam or sell unwanted products. These actions included in telephone spam are frequent today and, in addition to being annoying, put personal information at risk, since data that should not be disclosed arrives at a telephone number, for example, the codes used by verification systems. online accounts, including bank accounts.
That is why it is necessary to establish certain security measures that begin by not answering unknown calls and in the case of doing so, avoid providing personal information. Another good measure is to install caller ID applications, especially if the number of calls tends to increase over the days.
These applications identify the calling phone number before it establishes the phone connection. Many of them can also block numbers once the user has verified that it is phone spam. And they have an acceptable level of security because they use databases of numbers that are certain to be undesirable and those that the users themselves provide when allowing them to enter their phonebook. Here are two of the most important caller ID apps that you can download for free from your smartphone’s app store.
