Do you suspect that one of your contacts has been blacklisted on a Xiaomi smartphone, or do you want to add a bothersome subscriber? In this article, we will examine all the ways to check and manage call blocking/SMS on Redmi, POCO and other brands. The blacklist in MIUI works differently than on pure Android, so standard methods here do not always work.
Itβs important to understand that in Xiaomi, a blacklist can be hidden in non-obvious menu sections β especially after updates. MIUI 14/15. We will show you where to look for locks in new and old versions of firmware, how to check if your number is blocked on someone else's Xiaomi, and what to do if the standard settings do not work. MIUI It allows you to block calls selectively over time.
Where is the blacklist in MIUI: the official way
The easiest method is to use the built-in MIUI settings. However, the location of the item changed in different versions of the firmware. In recent updates (MIUI 14/15), the path became more logical, but in older versions (MIUI 12 and below), it could be βhiddenβ in unexpected places.
For modern smartphones (Xiaomi 13/14, Redmi Note 12/13, POCO F5/X5):
- Open the phone application (pipe icon).
- Slip on three dots in the upper right corner β select Settings.
- Go to the Blocking Numbers or Blacklist (some regional firmware may call the Blocked List).
- Here you will see all the locked numbers. To add a new one, click + and select a contact or enter the number manually.
For older models (Redmi 9/Note 10, POCO X3, etc.) with MIUI 11-12:
- π± Go to Settings. β Annexes β Phone. β Number locking.
- π Sometimes the item is hidden in Settings β System and device β Additionally. β Locking down calls.
- βοΈ In some firmware for India/China, the blacklist is called DND (Do not disturb) and is in the call settings.

If you have global firmware (EEA) and you don't have lock, try changing the region to India or Russia, which sometimes reveals hidden features.
How to check if your number is blocked on someone elseβs Xiaomi
There are a number of indirect ways to find out if you are blacklisted on someone else's Xiaomi phone, and they won't give you a hundred percent guarantee (especially if the owner uses third-party apps to block), but in 80% of cases they will help determine the status.
The main signs that you have been blocked:
- π The call is reset after 1-2 horns (or goes straight to voicemail).
- π¬ SMS Not delivered (no "delivered" status in your messenger).
- π V WhatsApp/Telegram Messages are sent but not read (gray boxes without the status "read").
- π The call passes, but after lifting the tube immediately breaks (characteristic of the function "List of exceptions" in the MIUI).
To check the lock more accurately:
- Call from another number to this Xiaomi. If the call goes well, you've been blocked.
- Send an SMS asking you to reply with "1" if the message is received. No response + no delivery status = blocking.
- Use services like Truecaller (if the phone owner has this app installed, it can show lock status).
Hidden blacklist features in MIUI: what the system can do
MIUI firmware offers advanced lock settings that many users are unaware of, such as:
| Function | Description | Where to turn it on |
|---|---|---|
| List of exceptions | Blocks all calls except for selected contacts (useful at work/night). | Settings β Do not disturb β Exceptions |
| Keyword Blocking | Automatically blocks SMS with certain phrases (e.g., βcreditβ, βshareβ). | Settings β Applications β Messages β Blocking |
| Temporary lockdown | Block the room for a certain period (from 1 hour to 30 days). | In the editing menu of the blocked number. |
| Lock log | Shows all blocked calls/SMS with time and number. | Phone β Settings β Lock Log |
The "Exclusion List" feature is especially useful, allowing you to create a "white list" of contacts that will make calls even if the "Do Not Disturb" mode is turned on, which is convenient if you want to filter out spam, but do not miss an important call from your family or work.

The blacklist doesnβt work: what to do?

How to export/import a blacklist to Xiaomi

- π Blocking by regular expressions (for example, all numbers with a prefix) +375).
- π Statistics of blocked calls with time/date graphs.
- π€ Automatic addition of spammer numbers from databases (Truecaller, Hiya).
- π Notifications of attempts to call from blocked numbers.
