How to block calls with certain prefixes on your Huawei mobile

When it comes to blocking calls on an Android mobile, we find a large number of applications available, many of which are known to users in Europe. In the case of Huawei phones, there is an application that comes natively on the devices that gives us several options to block unwanted calls.

Since we can block calls, block a certain phone number. In addition, it is even possible to block an entire prefix, to prevent phone numbers from a certain country from voting for you. A good option for users with a Huawei phone who want to avoid

How to identify and block unknown calls: no more SPAM

Discover the Android apps with which you can identify unknown calls and stop receiving spam or SMS calls.

Block an entire prefix on Huawei

Blocking an entire prefix assumes that you can block calls from a certain country. If there is a scam involving phone numbers from a specific country, you can use the Huawei app to block it. This is a little more drastic option than blocking a single number, but it can be useful for some users with a Chinese brand phone. If you want to use this option, the steps are as follows:

1. Open the Optimizer app on your Huawei phone.
2. Click on the Filter option.
3. Click on the gear icon at the top right.
4. In the new window that opens, go to the Blacklist section.
5. Click the Add button at the bottom of the screen.
6. Select the Filter Prefix option.
7. Enter the prefix you want to block (in international format, i.e. + (prefix)).

Once this is entered, your Huawei phone with EMUI automatically reject calls which come from said prefix. You won’t have to do anything else to avoid these types of calls on your phone. Anytime you want to add more prefixes, you can do so by following the same steps we have shown now.

The advantage of this system, as shown in the last step, is that the calls and messages from unknown numbers that begin with this prefix. This means that if you have a phone number in your address book that begins with this prefix, that number could call you because it is not an unknown number.
