How to block a private number

Would you block a private number? Well, the thing is feasible by taking advantage of the functions of Android and iOS that I told you about in the previous lines, but to do this you should first be able to trace the number that is hidden behind the private number.

How you do it? By using Whooming, a service available in the form of an app for Android (also on alternative stores) and iOS / iPadOS, which allows you to identify the numbers of those who call anonymously using the call forwarding.

Basically, when a call is received from a private number, it hangs up and it is automatically redirected to the Whooming number, which identifies the sender of the call.

Whooming can be used free of charge, but to know the entire private number in clear text, you need to take out a subscription starting from 12,99 euros for three months. If you want to use it, take a look at the guide in which I explain how to discover a private number and, when you have identified who is behind it, you can block it using the functions available on Android and iPhone.

However, if you use the app on Android Google phone, know that you can take advantage of a special function to block calls from unknown numbers in the bud. To activate it, open the app Telephone, press the three dots icon (top right) and go to the menu Settings> Blocked numbers. Then move up ON the switch lever next to the item Unknown And that's it.

How to block an unknown number

Are you going to block an unknown number, that is a number that is not present in the address book of your mobile phone? Let me tell you how to proceed on both Android and iPhone.

Android

I begin by telling you immediately that up Android there are no ad hoc functions to block numbers not saved in the phonebook. However, one thing you can do is to block the numbers in question via the report / spam feature available in the app Google phone.

To do this, after receiving a call from a number not saved in the phonebook, open the app Telephone, go to the section Recent, by pressing on the appropriate form at the bottom and identify the number of your interest.

Then make a long tap on it, select the voice Block / Report spam and touch the wording Block. In this way, you will no longer receive calls from the number in question. In other cases, if the number is not in your address book and it is a possible annoyance, it is the app itself that asks you whether to block the number or not: just tap on the appropriate wording to consent and that's it.

And if you are willing to install third-party apps, you can try Should I Answer, which allows you to block calls from known annoyances (eg call centers) and also those of numbers not stored in contacts: I explained how it works in this tutorial.

iPhone

Su iPhoneon the other hand, there is an ad hoc function for the preventive blocking of numbers not in the phone book, which can be activated from the system settings.

To use this, open the app Settings, by tapping on the gray icon with gears located on the home screen, presses on the items Phone> Silence unknown numbers and move up ON the switch located in correspondence with the wording Silence unknown numbers present in the new screen that opened.

From now on, calls from people not saved in your contacts will be blocked (unless you turn off the setting in question by going back to the menu Settings> Phone> Silence unknown numbers and moving on OFF the appropriate switch).

How to block a number on your landline

I conclude this guide by explaining to you how to block a number on your desk phone. The most modern landlines and cordless phones, both current and a few years ago, usually integrate functions that allow you to block calls.

The procedure for activating the function in question may vary from one phone to another, so I can't give you many instructions on this. However, usually you just need to go to the phone book settings or general phone settings and locate the lock function, if available. I strongly suggest you read what is indicated in the user manual of the phone: there you will find all the relevant information.

Also, know that you can block a number by reporting it to your landline operator, especially if your phone does not have the call blocking feature. For more information about the function in question and any costs to be incurred to activate it (since it may not be free), contact your operator (eg TIM, Vodafone, WINDTRE or Fastweb).
