Modern Xiaomi smartphones provide powerful tools to filter unwanted calls, allowing users to effectively combat spam and intrusive subscribers. Often, you add a number to a blacklist to avoid communication, but eventually forgot about this action. Now that communication with this person is again necessary, the question arises: where exactly is the list stored in the system and how to quickly find it.
The interface of the MIUI shell or the new HyperOS can be confusing because of the deep nesting of the settings menu. The standard path through the phone book is not always obvious to beginners, especially after major system updates that change the location of controls. In this article, we will discuss in detail all possible ways to detect hidden numbers.
It is important to understand that the blockage can occur at the level of the SIM-Maps, system application "Phone" or third-party antivirus. the system blacklist Xiaomi is stored locally on the device and is not synchronized with the Google account by default, so the search should be conducted in the settings of the gadget. We will consider standard methods that do not require the installation of additional software.
Search through the standard application "Phone"
The fastest and most logical way to find out which numbers are locked on your device is to look at the settings of the call app itself, which handles incoming calls and applies filtering rules. To start, open the standard caller, which usually has a green or blue icon on the home screen.
In the upper right corner of the interface, you'll see a three-dot icon or a gear that represents the settings menu, and if you click on it, you'll be taken to the call settings section. You'll need to find Lock Settings or the Blacklist. The name may vary slightly from firmware to firmware, but the load remains the same.
When you go to this section, you'll see a full list of currently locked numbers, where you can not only view the list, but also edit it, add new entries or delete old ones, and you can flexibly manage access to your device.
💡
If you don’t see the “Black List” item on the menu, try switching the region in your phone settings to “India” or “Russia”, as in some regions (e.g. the EU) the blocking functions may be restricted by law.
Pay attention to the possibility of setting lockdown rules, which means that you can not only block calls to specific subscribers, but also, for example, all hidden numbers or unknown contacts, which creates an additional level of digital security and comfort.
Use of the Security App
In the Xiaomi ecosystem, the central node for access and filtering rights management is the Security system application, which has a green lightning icon and combines antivirus, memory cleaner and call blocker functions, a method that is especially relevant if you can not find the desired item through the call menu.
Run the app and find the Blacklist section in the tool list. If the tool doesn't have one on the home screen, click three dots in the corner and select Settings, then look for the section related to blocking. SMS-message.
☑️ Checking the Blocker settings
Inside this section, the information is structured by the types of lock, which are calls and messages, and you can see how many times a caller has tried to reach a particular call, even if the phone hasn't ringed or vibrated, which helps you figure out whether to keep the number locked further.
⚠️ Warning: Removing a number from the blacklist in the Security app instantly lifts the call ban.Make sure you really want to reconnect with that contact.
Security also allows you to import and export lock lists, which is convenient when changing your device, so you can save the unwanted number database to a file and transfer it to a new Redmi or POCO smartphone.
Checking settings SIM-card-and-operator
Keep in mind that blocking can be done not only by the software of the smartphone, but also at the network level of the operator. Many users have activated the service "Blacklist", which is managed through USSD-commands or personal account of the operator, regardless of the settings of the phone.
To check the status of the lock on the operator side, you need to use service codes. They vary for different mobile networks. For example, to check the list of blocked numbers, commands like *111*44# or similar, depending on your region and provider, are often used to check the list of blocked numbers.
| Operator. | Team checklist | Addition command | Remove command |
|---|---|---|---|
| MTS | *111*44# | *111*44*1*number# | *111*44*0*number# |
| Megaphone | *130# | *130*number # | *130*0*number# |
| Beeline | *110*771# | *110*771*number# | *110*771*0*number# |
| Tele2 | *120# | *120*number # | *120*0*number# |
Using these commands will allow you to see a list of numbers that the operator does not miss on your phone. SIM-Check the plan before activating.
If the number is locked by the operator, no manipulation of the settings of the Xiaomi phone will help unlock the call. the Subscriber will hear the beeps or message of inaccessibility, and you will not see missed calls in the log.
Analysis of third-party applications and messengers
Often users forget that the lock may have been made inside specific apps, such as Viber, WhatsApp or Telegram.These messengers have their own independent ignoring lists that are not displayed in the system phone book.
To find blocked contacts in messengers, you need to go to the settings of each application separately. This section is usually located in the Privacy or Blocked menu, where you will see a list of users who can not contact you through this service.
In addition, third-party number detectors such as GetContact or NumBuster can be installed on the phone, they also have their own databases and can block calls at their level, intercepting a call before the system call. Check the settings of such applications if standard methods have failed.
Why can a number be blocked in one app but not in another?
It is recommended to periodically review the lock lists in all installed communication applications, this will help to avoid awkward situations when you expect an important call, and it is lost in the bowels of one of the messengers.
Specifics of different versions of MIUI and HyperOS
The MIUI shell interface is constantly evolving, and with the release of the new HyperOS, the location of some elements may have changed. Owners of older models such as the Redmi Note 9 or Xiaomi Mi 11 should consider the Android version and shell when looking for settings.
In recent firmware versions, Xiaomi is actively integrating with cloud-based spam locking services, which means settings can be pulled up from your Mi Account. If you change your phone, check if the old blacklist syncs with the new device automatically.
Also worth noting are the differences in global (Global) and Chinese (CN) firmware versions: In Chinese versions, the blocker functionality is often extended and has more aggressive default settings, including blocking SMS with specific keywords.
⚠️ Warning: When you reset your phone to a factory setting, the local blacklist will be completely deleted. Take a screenshot or export important numbers in advance if you plan to flash it back.
If you upgraded to HyperOS, look for a new design of the settings menu. The lock control points could be moved to the Privacy Protection section or highlighted in a separate category at the top of the settings screen.
What to do if the desired number is not found
There are times when you're sure that the number is locked, but none of the lists listed it, in which case it's worth checking Do Not Disturb mode, in which the phone can drop calls from all but select contacts, creating the illusion of locking.
Check the settings in Settings → Sound and Vibration → Do Not Disturb. Make sure there are no restrictions on calls from Unknown Numbers or that there is no activation of sleep mode, which can drown out the sounds of a call at certain times.
💡
Not having a blacklisted number doesn't guarantee that calls are going through. Check Do Not Disturb mode, network status, and call forwarding availability.
Another cause could be carrier-side issues or temporary network failures. Try rebooting your device to update your network login. If the problem persists, contact your mobile operator's technical support.
