Xiaomi, Redmi and POCO smartphone owners regularly face the challenge of blocking unwanted calls, from intrusive marketers to scammers. Unlike iPhones or naked Android, MIUI offers several tools to manage incoming calls, but not all of them are obvious. For example, few people know that Xiaomi can block all calls except for selected contacts or set up automatic deviation on a schedule.
In this article, 5 proven ways to ban calls on Xiaomi devices (relevant to MIUI 12-14 and HyperOS), including hidden features that are not mentioned in the official documentation.

- ๐ง Hidden codes MIUI โ Engineering menu for advanced users
- ๐ค Third-party applications โ when standard tools are not enough
We will focus on the difference between phone-level and carrier-level locks, which is critical to understanding why some numbers still pass, and we will also explore the myth of โcomplete call lockโ and explain why Xiaomi does this differently than other brands.
MIUI blacklist: How to add a number to the lock
The most obvious way is to use the built-in blacklist in the Phone app, but even here there are nuances: for example, in MIUI 14, the blocking algorithm has changed, and now it automatically filters potential spam (Spam Protection feature).
To manually add a number:
- Open the Phone application โ go to the Journal tab.
- Find the right number, click on it. โ choose โฎ (three-point) โ Lock down.
- Confirm the action. The number will be added to the Settings list. โ Number locking.
For mass addition:
- ๐ Go to Settings. โ Annexes โ Phone. โ Number locking.
- ๐ Click Add and select numbers from contacts or enter manually.
- ๐ Enable the option to Block Unknown Numbers (caution: this will block all numbers not saved in contacts!).
Added number to the lock list?|Is the option "Block Unknowns" enabled"?|Is the journal checked for duplicate numbers?|Is the phone app updated to the latest version?-->
Important: blacklisting does not work for emergency numbers (112, 911, etc.) and some service messages from the operator, and if the caller hides his or her number (Unknown or Private), it will have to be blocked separately.
โ ๏ธ Attention: B MIUI 13 and older, blocked numbers are not displayed in the call log, they can only be seen in the lock list. If you need to keep a record of such calls, use third-party applications (section 5).
2.Do Not Disturb Mode: Flexible lock setting
Xiaomiโs Do Not Disturb (DND) feature not only allows you to turn off notifications, but also completely ban incoming calls โ both for everyone and selectively โ which is convenient if you need to temporarily disconnect (for example, in a meeting or at night).
How to set up:
- Go to Settings โ Sound and vibration โ Do not disturb.
- Activate the slider Do not disturb.
- Click the Schedule to set automatic turn on (for example, from 23:00 to 8:00).
- In the Calls section, select: ๐ Block everything โ complete lock (except repeated calls from one number within 3 minutes). ๐ Contacts only โ only miss calls from saved numbers. โญ Favorite Contacts โ Create a White List.
Xiaomi's feature is that DND allows you to call again from the same number for 3 minutes, which is for emergencies, but can get in the way if you get annoyed by the same scammer.
Settings โ Sound and vibration โ Do not disturb โ Additional โ Repeated calls โ Turn off| DND parameter | MIUI 12-13 | MIUI 14 / HyperOS |
|---|---|---|
| Blocking all calls | Yeah, except for repeats. | Yeah, with the re-setting. |
| White list of contacts | Only the elect. | Contact Groups + Selected |
| Automatic schedule | Yes, but without flexible exceptions. | You can adjust the day of the week. |
| Exceptions for alarm clocks | No. | Yeah (in HyperOS) |
โ ๏ธ Attention: If, after activation, DND Calls still pass, check your Priority Notifications settings in the same menu. Some system applications (e.g., Security) may ignore Do Not Disturb mode".
3. Blocking calls through the operator: instructions for MTS, Beeline, MegaFon, Tele2
If embedded facilities MIUI They canโt cope (for example, scammers use number swapping), you can block calls at the level SIM-Each operator has its own conditions:
- ๐ถ MTS (Russia/Belarus/Kazakhstan): USSD-code: *111*081# โ Follow the instructions. Personal account: section Services โ Number lock. Limitation: up to 30 blacklist.
- ๐ถ Beeline (Russia): USSD: *110*789# โ Choosing the "Black List" option: 3 rub/day-for-service.
- ๐ถ Megaphone: USSD: *105*001# โ Add a number. Feature: blocks and SMS.
- ๐ถ Television2 (Russia/Kazakhstan): USSD: *220*1# โ Antispam service, free for subscription fees > 300 ruble.
- ๐ถ kistar/Vodafone (Ukraine): USSD: *111*321# (kistar), *111*5# (Vodafone.Limit: 100 blacklist.
The advantage of operator lock: it works even with or without the phone turned off SIM-There are some downsides to the maps:
- โ Numbers are blocked only on the home network (roaming may not work).
- โ Some operators charge a fee for the service.
- โ It is difficult to manage the list (you need to call for support or use it). USSD).
What if the operator does not block the number?
4 Hidden MIUI codes for blocking calls
For advanced users, Xiaomi has an engineering menu and service codes that allow you to manage the lock at a low level. These methods are not documented, but work on most devices (tested on Redmi Note 10 Pro, Xiaomi 12T, POCO F4).
Method 1: Locking all incoming calls
Enter the phone in the appendix:
##4636##Go to Phone Information โ Menu (three dots) โ Call settings โ Inbound lock.
- ๐ Enable Locking All Calls (Reboot Required).
- ๐ต Add numbers to Exclusions (white list).
Method 2: Disabling calls via ADB (for developers)
If you have unlocked bootloader and enabled debugging over USB, you can disable calls with the command:
adb shell settings put global call_blocking_enabled 1To unlock:
adb shell settings put global call_blocking_enabled 0๐ก
Before using the engineering menu, back up your data via Settings โ About Phone โ Backup. Some changes may result in resetting your network settings.
โ ๏ธ Warning: Changes to the engineering menu may disrupt the work SIM-If after manipulation, the phone stopped catching the network, reset APN: Settings โ SIM-maps and mobile networks โ Access points (APN) โ Reset to factory
Third-party applications: when standard tools are insufficient
If the built-in MIUI tools are not satisfied (for example, you need to keep a log of blocked calls or analyze spam), you should consider third-party solutions.
| Annex | Features | Cons | Reference |
|---|---|---|---|
| Truecaller | Spam number database, blocking by category (fraudsters, marketing) | Requires access to contacts, advertising in the free version | Google Play |
| Hiya | Geolocation blocking, risk analysis of the number | Paid functions for extended locking | Google Play |
| Call Blocker | Blacklist/whitelist, keyword blocking (e.g., โbankโ) | The interface is outdated, there is no Russian language | Google Play |
| Should I Answer? | Usersโ rating of numbers, automatic blocking by rating | Few reviews about Russian/Ukrainian numbers | Google Play |
When choosing an application, pay attention to:
- ๐ Permits: Avoid programs that request access to the SMS geolocation without cause.
- ๐ Database: Truecaller or GetContact are better suited for Russia/CIS.
- ๐ Synchronization: Some applications (like Truecaller) sync contacts to their servers.
Important: Once you install a third-party blocker, turn off the built-in spam protection in MIUI to avoid conflicts:

Even after you set up the lock, Xiaomi users face typical problems, and let's look at the most common ones:
Problem 1: Locked numbers still ring
Causes and solutions:
- ๐ Cache of the application "Phone": clean it in Settings โ Annexes โ Phone. โ Warehouse โ Clear the cache.
- ๐ก Double. SIM: The lock can only work for the main SIM. Check the settings for each card separately.
- ๐ต๏ธ Spoofing: Scammers can call from multiple numbers. Use apps like Truecaller to analyze.
Problem 2: Do Not Disturb is not working.
Checklist for diagnosis:
Is the mode on in the sound settings?|Checked out the contact exceptions?|Updated to the latest version?|Is there a conflict with third-party blockers?-->
Problem 3: The operator does not block the number
Possible causes:
- ๐ The number is registered as โimportantโ (banks, public services).
- ๐ The call is via VoIP (WhatsApp, Viber) โ the operator can not block it.
- ๐ The lock service is not activated (check through the USSD personal account).
๐ก
If the number is ringing via messengers (WhatsApp, Telegram), block it directly in the caller application. The operator and MIUI cannot block VoIP calls.
