Have you blocked an important number by mistake or want to get contact back from the blacklist on Xiaomi?The problem is that after the MIUI 14/15 updates, standard unlock paths often change, and some menus are hidden. In this article, 5 proven ways for all models, from the Redmi Note 12 to the flagship Xiaomi 14 Ultra. Let's figure out how to remove the number from the locked through the phone's settings, the Contacts app, as well as little-known methods for cases when the standard options do not work.
Many users find that when they lock a number, it disappears from their contact list or doesn't show up in their call log. It's not a mistake, because that's how the MIUI blacklist works. But you can get it back 90 percent of the time, even if you don't remember exactly how you blocked it, and the key is to know where to look.
If the number was blocked through a telecom operator (for example, on request in the salon of MegaFon / MTS), then it can be unlocked only through the operator.
Method 1: Using standard MIUI settings (fastest)
This is the basic method that works on all versions of MIUI from 12 to 15. Suitable for most models: Redmi 10/11/12, POCO X3/X4/X5, Xiaomi 11T/12/13/14.
Instructions:
- Open the phone application (pipe icon).
- Click on the three dots in the upper right corner → select Settings.
- Go to the section "Block numbers" (or "Black list" in old versions).
- Enter a password/pattern lock if you request security.
- Find the blocked number in the list and swipe it left or click on the basket.
⚠️ Note: On some firmware (for example, MIUI Global for the European market), the "Blocking" section may be called Spam and Block. If you do not find a paragraph, check the interface language.
☑️ What to do if the "Blocking" section does not appear
Method 2: Contact the App (if the number is saved)
If you have a locked number in your phone book, you can unlock it directly from the Contacts app, which is convenient because it does not require a menu search – everything is done in 2 clicks.
How to unlock:
- 📱 Open the Contacts app (the icon with the man).
- 🔍 Find the right contact through search or scroll through the list.
- 📞 Press the contact. → three-point → Unblock (or Unblock).
- ✅ Confirm the action in the pop-up window.
If there is no Unblock, then the number was blocked not through contacts, but through another menu (for example, from the call log).
💡
If the number still doesn't ring after unlocking, check if the "Do Not Disturb" mode for that contact is activated. This is done in the contact settings → "Notifications".
Method 3: Through a call log (for unsaved numbers)
Numbers that are not saved in the phone book but were locked after an incoming/outgoing call can be unlocked directly from the log.This method works even on the POCO F5 and Redmi K60 with the latest updates.
Step-by-step:
- Open the phone application → tab Journal.
- Find the number in the list that is blocked (it can be highlighted in red or gray).
- Click on the number → at the bottom will appear the Unlock button (or the lock icon).
- Confirm the action.
⚠️ Attention: Some firmware has locked numbers hidden in the log. To see them, click three dots in the log. → Show blocked.
Method 4: Through the Hidden Menu of Engineering Settings (for the experienced)
If standard methods don't work, you can try unlocking the number through an engineering menu, which is suitable for advanced users and requires caution - wrong actions can disrupt the phone.
Instructions:
- Open the phone app and enter the combination: ##4636##
- Select Phone Information (or Phone Information).
- Scroll down to the Call Lock section.
- Find the blocked number and remove it from the list.
| Xiaomi model | Engineering menu code | Section of lockdown |
|---|---|---|
| Redmi Note 12 | ##4636## | Phone Information → Call Blocking |
| POCO X5 Pro | ##36446337## | Engineering Mode → Call Settings |
| Xiaomi 13 Ultra | ##4636## | Phone Info → Blocked Numbers |
| Redmi 10C | ##36446337## | Engineer Mode → Call Block |
⚠️ Warning: Do not change other options in the engineering menu unless you are sure of their purpose.This may result in loss of network signal or reset of network settings.

Method 5: Reset the settings of the Phone application (extreme case)
If none of the methods worked, there may have been a crash in the lock database, in which case resetting the Phone app will help, which will delete all the locked numbers, but save the call history and contacts.
How to reset:
- Go to Settings → Applications → Application Management.
- Find the Phone (or Phone) app and open it.
- Press Warehouse. → Clear the data.
- Confirm the action.
Once reset, all blocked numbers will be removed from the blacklist, but this method will also reset:

- 📱 Quick dial settings
💡
Resetting the Phone app is the last option when other methods don’t work. Back up important contacts through Settings → Google → Backup before performing.
