How to block incoming calls from unknown callers and hidden numbers on iPhone

When is the function of barring incoming calls from hidden numbers useful?

It is logical to assume that subscribers who have reasons to hide it most often use the number hiding service. It can be taxi services that often call from GSM gateways because they do not want to be called back to the gateway number, and representatives of various other companies. Sometimes, even your friends can call you from a hidden number in order to intrigue or prank you. However, collectors, scammers and other unpleasant personalities often use similar techniques.

From my experience, I can say this: the number hiding service was most often used by people with whom few people want to communicate. As a rule, the calls of such people are not answered, and their phone numbers are blacklisted. Therefore, a call from a hidden number is one of their methods to get through to someone who does not really want to talk to you.

And the function of barring calls from unknown subscribers actually adds the hidden number to the black list.

What is a hidden number

Number hiding is one of the functions of GSM networks. As a rule, any mobile operator has a paid service of hiding the number. Different operators may call it differently: either “Anti-identifier”, or “Incognito”, but the essence is the same, since based on the ability of the GSM, 3G, 4G or 5G network to hide the Caller ID of the caller.

If the subscriber has paid for such a service, he can choose to hide or show his phone number during a call. When you receive a call from a hidden number, instead of numbers or a name, the following is displayed on the phone screen: Number is hidden, Unknown or Anonymous.

Why calls from unknown phones are dangerous

Nowadays, the function of blocking calls from unknown numbers is becoming more and more popular. the number of spam calls is increasing exponentially every day. Nowadays, more and more people complain that they are constantly called by some strange people (and sometimes robots) from unfamiliar numbers, distract from business, and very often also wake up in the early hours of the weekend, which cannot but annoy.

In about half of the cases, when answering a call from an unknown number, the person hears silence or the call is immediately dropped. If, when answering such a call, you hear silence or music, then most likely it is a call from some call center. They know that in half of the cases people simply do not pick up the phone from an unfamiliar number or drop such incomprehensible calls. Therefore, spammers start dialing several numbers at once, so there may not be enough operators. This is how call centers of banks, telecom operators work, who call people to offer them to get a card or take part in some action.

For a modern sane person, it will not be difficult to distinguish a normal call from a “divorce”. However, children or elderly family members who have personal mobile phones are best protected from such contacts.
