Unfortunately, telephone scams have become common in recent times, either through calls or smishing, those carried out by SMS, generally using the identity theft technique to confuse the victim.
There are numerous tools, some even installed by default on mobile phones, that are used to filter phone spam and will block or at least warn of previously reported dangerous numbers. However, we can also take more general measures to heal ourselves, such as blocking any type of communication from a specific telephone prefix.
Block entire phone codes
On many occasions we receive SMS or calls from international telephone codes and that will make us suspicious, since it will depend on each person if that can happen or if it is virtually impossible. If the latter is your case, you can cut your losses and block it completely.
It will depend on the brand of your mobile and the version of the operating system you have (even the custom Android layer that your brand carries), but this option has become commonplace.
On Xiaomi , one of the most popular smartphone brand, this security setting is part of MIUI. You will simply have to open the Phone application, where you can see contacts or recent calls. Next, press the menu dropdown button and Call settings. Finally, access the block list and press “Add prefix”. Enter the one you want to completely block, and you’re done.
In the event that your phone is Samsung , you can also do it in its One UI layer. Again, go to the Phone app on the Korean brand phone, press the menu button and choose Blocked Numbers. Finally, enter the international phone code you want and change the match option from exact to partial.
In Huawei EMUI, the app to choose first is Phone Optimizer and then tap on Filter. The next thing is to click on the Filter rules option and then on Black list, where you will have to click on the add option and then click on filter prefix.
Apps that help you avoid dangerous numbers
As you will see, although they are three of the most popular brands, it is more than likely that you have other mobile phones or that you use the Google Phone application on Android instead of your brand’s native one.
It never hurts to install a caller identification application on your smartphone. These are not only for dangerous numbers, but can also report phone spam, which can save you wasting time with certain business calls.
From here we recommend some of the ones that work best for us, such as Mr. Number, Hiya, CallBlocker, TrueCaller or Pepeescudo . These applications will not only allow you to have greater control over the numbers you have blocked, but also give you some peace of mind by identifying the incoming call and displaying an alert on the screen in case it is a suspicious number.
