How to Unblock a Subscriber from the Blacklist on Xiaomi

The situation when an important call does not arrive on the device due to an erroneous lock is familiar to many owners of Xiaomi smartphones. Often users in the heat of emotion put a number on a blacklist, and then forget about it or do not know how to return it all back. MIUI and HyperOS system have several levels of protection against spam, which sometimes creates confusion when searching for the desired menu.

Reconnecting with a contact requires care, as the paths to settings may vary depending on the operating system version and the type of call used. The standard Android interface and MIUI offer different algorithms that need to be clearly distinguished. In this article, we will discuss in detail all the ways to quickly remove the ban on calls.

Filtering features that are not working properly often cause missed business conversations or important messages from loved ones. Understanding the principles of anti-spam will allow you to flexibly manage incoming traffic. We will look not only at standard methods, but also at the nuances of working with system applications.

Checking the standard lock settings in MIUI

The first step should always be to check the built-in tools, as they are the ones that block incoming calls most often. In Xiaomi smartphones, the Security app, which is integrated deep into the system, is responsible for this, and the list of blocked numbers is accessed through the filter control center.

To log in to the menu, you need to run the Security app and find the Antispam section. This stores all the restrictions settings, including SMS and voice calls. The interface may vary slightly between different versions of the firmware, but the logic remains the same for all devices of the brand.

⚠️ Note: Some carriers provide their own locking services that work regardless of the phone's settings. If there are no bans on the smartphone menu, contact the operator.

Once you go to the list management section, you'll see a list of all the numbers that have been added manually or automatically, and you'll be able to delete the contact instantly, and you'll be able to reconnect immediately, and it's important to check if you've activated Do Not Disturb or blocked unknown numbers.

  • 📱 Open the Security app on the home screen.
  • 🛡️ Select “Antispam” in the lower menu or in the tool list.
  • 📞 Click on the gear icon or the Black List button in the upper right corner.
  • 🗑️ Find the desired number and press the delete button or basket icon.

Managing Contacts Through Standard Google Call

Many Xiaomi models, especially global versions, come with a standard call from Google instead of the proprietary MIUI Dialer. In this case, the algorithm of actions changes dramatically, as the interface and location of settings are completely different.

To unlock a subscriber, you need to go to the recent tab or the Contacts tab and find the number you want, and if you click on it or the information icon (the letter "i" in the circle), you will open a call card, and that's where the lock control button is hidden, which can be active.

Why are the phone interfaces different?
Global versions of Xiaomi smartphones for Europe and Russia often use Google services by default, while the Chinese versions are equipped with their own MIUI Dialer shell.

If the number is indeed locked, you will see the Unlock Number button or the switch with the appropriate name, clicking on this element immediately removes the ban, and it is also worth checking the settings of the call itself by going to the three-dot menu and selecting Settings → Locked Numbers.

  • 📞 Launch the Phone app (blue handset).
  • ℹ️ Click on the “i” icon next to the contact name or number.
  • 🚫 Find the "Block the Number" and turn it off.
  • ✅ Confirm the action in the pop-up window.

Working with MIUI's branded caller

Owners of Chinese versions of smartphones or devices that have not been installed Google services, use the branded green call MIUI. Here the management logic is slightly different, and the settings can be hidden in the depths of the call menu. Unlock requires you to go to a specific section of the call settings.

You have to open the call app and click on a menu of three bars or dots to enter the settings. You have to look for the "Antispam" or "Blacklist" option in the settings list, and that's where the database of prohibited contacts is located, which the system checks every time you call in.

Once you log in, you can see all the locked records, and to unlock, you just need to select a number and select the "Delete" or "Unlock" action, and the system can request confirmation of the operation to avoid accidentally removing important restrictions.

⚠️ Attention: When cleaning the cache of the Phone app, the blacklist settings are usually saved, but in rare cases can be reset to factory.Be careful when cleaning the system deeply.

The branded shell also allows you to create complex rules, such as blocking all hidden numbers or numbers from other regions, and check if global filters are activated that can automatically block the subscriber you want, even if he or she is not on the personal list.

  • 📲 Open the green icon of the call MIUI.
  • ⚙️ Go to settings via the menu (three dots/stripes).
  • 🚫 Select "Antispam» → «Blacklist».
  • ✋ Remove contact from the list of prohibited.

Use of third-party applications and synchronization

Often users install additional spam protection applications, such as Kaspersky Who Calls, NumBuster or Truecaller, which have their own databases and can block calls regardless of Android or MIUI settings. If standard methods did not help, the problem may lie in third-party software.

You have to check the list of installed applications and find the antivirus or number detectors, and when you go into the settings of such an application, you have to find the lock section and check if you have the right contact, and when you delete the number from the database of a third-party application, you often solve the problem instantly.

If the number was locked on another device linked to the same account, the ban can automatically apply to your Xiaomi. Checking the block list through the Google Contacts web interface will help identify such cases.

Do Not Disturb Mode and Hidden Settings

Sometimes, the caller can't get through not because of a blacklist, but because of an activated Do Not Disturb mode, in which the smartphone can drop calls or not emit audio signals, creating the illusion of blocking, and checking this mode is an important stage of diagnosis.

This mode is activated, usually through the notification curtain or in the Sound and Vibration settings. In the mode settings, you can configure exceptions by allowing calls from selected contacts or re-calls. If your number is not on the exception list, the call will be blocked by the system.

💡

Use the Repeat Call feature: If the same number rings twice in 15 minutes, the second call will even go into Do Not Disturb mode, a useful setting for emergencies.

There are also hidden codes and engineering menus that can affect call forwarding, such as activating a redirect to voicemail or another number can be perceived as a lock by the subscriber. Check the redirect settings in the call menu by dialing the ##002# code to reset all redirects.

  • 🌙 Check the active modes in the notification curtain.
  • 🔊 Go to "Settings» → «Sound and vibration» → «Don't disturb».
  • 📞 Check the call forwarding settings.
  • 🔄 Reset your network settings if the problem persists.

Specificity of unlocking on different versions of Android

The Android version (10, 11, 12, 13 and later) makes its own adjustments to the menu layout. With each update, Google changes the structure of its privacy settings by moving the lock controls. On older versions of the MIUI based on Android 9-10, the settings can be more scattered.

Newer versions of Android (12+) have increased control over app permissions, callers must have permission to display over other windows and access contacts to handle lock lists correctly, and if permissions are revoked, the blacklist feature may not work properly.

Owners of HyperOS devices should look into new smart locking features that analyze callers behavior, which can automatically flag numbers as spam based on complaints from other users and block them without your knowledge.

⚠️ Warning: After a major firmware update, the blacklist settings may be reset or moved.Always double-check the lists after the system update.

The differences in the interface can be significant, so if you don’t find a menu item, try searching by settings. Type the word “lock” or “blacklist” in the search box for smartphone settings, and the system will specify the desired section.

Frequently Asked Questions (FAQ)

Will the customer see that I have unlocked it?
No, Xiaomi and Android do not send any notification to the user that his number has been removed from the blacklist.
Will SMS messages sent while the number was locked?
In the standard MIUI configuration, messages from locked numbers are not saved and permanently deleted. However, in some firmware versions, there is a separate "Blocked Messages" folder in the Messages app where they can go. Check this section before removing the contact from the list.
Can I unlock the number remotely if the phone is turned off?
No, all blacklist settings are stored locally on the device. Remote management is possible only through synchronization with a Google account (for contacts), but the call lock feature itself requires the phone to work actively, unlocking will occur when the device is turned on and the settings are synchronized.
What if the number is not removed from the blacklist?
If the delete button doesn't work, try restarting your smartphone. If the problem persists, check if the number is part of the group or is not fixed in the operator's system settings, and if you want to reset your call settings through the engineering menu or reset your network completely, you can do the best.

💡

Timely checking of lock lists in all possible sources (system, call, third-party applications) is the only way to ensure that important calls are not missed.
