In this article I am going to explain all the different ways you have to do it, whether you use Android or iOS.
Let’s go there!
How to Block a Hidden Number on Android
How to block calls from private or hidden numbers on Android will depend on the brand of your device. Most of the major manufacturers have their own systems to block hidden calls, as you will see a little later.
Now, I am also going to explain how to block calls from unknown numbers on any device, regardless of brand.
How to Block a Hidden Number According to the Manufacturer
As I have said, Xiaomi, Samsung or Huawei have their own systems to block private numbers. The best thing about this is that the way to do it in your interface It doesn’t differ too much from one brand to another.which makes it much easier for me to explain how to do it.
I will take a Samsung phone as an example for it. How to block a private number on Samsung is easy by following these steps:
- Access the Phone app on your device.
- Click on the three points that you will find in the upper right part of the screen.
- In the dropdown that will appear, select settings.
- Tap on Block numbers. It should appear at the top of the screen.
- Activate the option block unknown numbers.
Once we activate this option we will no longer receive a call from a private or hidden number. If you are worried that in this way you may miss a specific call, you can always turn it off at any time following the same steps.
How to Stop Unknown Numbers from Calling me with an App
My recommendation is that, first of all, you always try to do the process that I have taught you just above. Now, in the event that your Android device does not have the same or similar system to the one mentioned, the solution that you can go to is through install a third-party app to avoid receiving calls from unknown numbers.
In the application stores there are several applications to block calls that are very interesting and completely free. As a personal recommendation, I would like to advise you to opt for Blocker – Calls Blacklista very simple to use app, with a very intuitive interface and that will also consume very few resources from your phone.

Both are perfect for blocking a private number that keeps calling.

Blocking an unknown number on iPhone is also possible, although with certain nuances. Contrary to what happens with Android custom layers, here there is a way to block private numbers, but not in a concrete way. In other words, you can only block calls from numbers you don’t have saved.
