It should be borne in mind that to carry out this process, your android OS should be 8.0 or higher. The changes to be made are practically the same on all Android devices, however, depending on the brand or manufacturer of the device, the process of blocking calls from unknown numbers may vary slightly.

The big advantage of having a operating system equal to or greater than 8.0 is that you will not have to resort to additional applications,  saving internal memory. Here we explain how to block calls from unknown numbers depending on the phone brand.

Block calls from unknown numbers on Huawei

Huawei has a feature known as harassment filter, where you can find the blacklist. There you can exclude unknown contacts or numbers, preventing those numbers from texting or making calls to us.

To apply this configuration you need to log in to the application Phone Manager and select the option Filter. Once there, you'll need to select the settings option (the gear icon in the top right corner).

Once there, we will see several options:

  • Interception rules
  • Black list of numbers
  • Blacklist of keywords
  • White list of numbers
  • Notifications

Interception rules

In this option we can configure the device to block one or all unknown contacts, incoming calls and all messages from unknown senders.

Black list of numbers

This option allows you to select one or more numbers and add them to the blacklist. In this way the numbers will be blocked, preventing the entry of calls and messages.

Blacklist of keywords

In this configuration we can select a list of keywords and all messages from unknown numbers that contain these words will be blocked and will not arrive.

White list of numbers

Unlike the black list, all the numbers of this one list will be able to send messages and make calls to our number.


In this option we can change the settings of the blocked numbers and contacts that are not blacklisted.
