Owners of Xiaomi, Redmi and POCO smartphones often face the need to restrict access to certain phone numbers in their device, which can be motivated by the desire to hide personal data from children, colleagues or simply keep important conversations confidential. However, the standard shell of MIUI and its successor HyperOS do not have one universal “Hide” button for the entire phone book, which often leaves users baffled.
Making matters worse, the methods of hiding are heavily dependent on the version of the Android operating system and the specific interface modification, and in some cases, the concealment through the settings helps. SIM-In some cases, using built-in security features, and in others, installing specialized software, it is important to understand that full encryption of the contact is not always possible with standard means, but there are effective workarounds.
In this article, we will take a look at all the ways you can hide numbers, from simple settings to advanced methods using third-party applications, and learn how the contact visibility mechanism works in the Xiaomi ecosystem and what security restrictions are placed on accessing data.
Standard Contact Visibility Settings in MIUI
The first thing to do before trying to hide data is to check the current display settings. Often users confuse “hiding” with “filtering.” In the standard Xiaomi Contacts or Phone app, there is a menu that allows you to choose which sources to show numbers from. If you accidentally turn off your display SIM-Google Maps or Accounts Create the Illusion of Missing Data.
To check, go to the Contacts app, click three dots in the corner of the screen and select Settings. Here you are interested in Displayed Contacts. Make sure that the tick is next to All Contacts. If you select Phone Only here, the numbers saved to the SIM-In the cloud or in the map, they will be invisible in the list, although they will remain physically on the device.
⚠️ Warning: Changing your display settings doesn't hide contacts from outsiders if they pick up the phone and go into the settings. It's just a filter for your convenience, not a privacy tool.
There is also a nuance with duplicates: MIUI can combine the same records from different sources. If you hide a number in one source but leave it visible in another, the combined record will still be displayed. For effective access management, it is recommended to desynchronize sources or use the method described below.

Before making changes to your settings, export the entire phone book to a.vcf file, which will allow you to quickly recover data in the event of accidental deletion or sync failure.
Hiding contacts through settings SIM-map
One of the oldest and most proven methods that works on almost all versions of Android, including Xiaomi smartphones, is to store numbers directly on the chip. SIM-The logic is simple: if the phone doesn't see, then it hides the source» SIM-map as a source of contacts, and the numbers stored on it will not be displayed.
To implement this method, you will need to move the numbers you need first. Go to Contacts, select the number you want, click Change or Move, and select the target SIM 1 or SIM 2 storage. Once the sensitive numbers are on the SIM, you can start masking them.
1.Move the contacts to SIM-map
2. Go to the display settings
3. Uncheck the box SIM-map
4. Check the contact list-->
Next, you need to go to the display settings, as described in the previous section, and remove the tick from the display of contacts. SIM-As a result, the numbers on the chip will disappear from the general list, but this method has a significant disadvantage: modern smartphones often work slowly with contacts on the chip. SIM, The memory of the chip is limited, which does not allow you to save additional data, such as a photo or email.
| Parameter | Phone storage | Storage on SIM | Storage on Google |
|---|---|---|---|
| Memory capacity | No restrictions. | Limited (usually 250) | No restrictions. |
| Additional fields (photos, social networks) | Available | Unavailable. | Available |
| The possibility of concealment | Only through the apps | Through visibility settings | Through account settings |
Use of the built-in "Security" application
The MIUI shell features a powerful system tool called Security, which, while its primary function is virus protection and garbage cleanup, some firmware versions (especially those in China and the global stable versions of past years) featured a “Hide Contacts” or “Privacy Protection” feature.
Find an app with a green shield icon on your desktop or in the Tools folder, and run it and scroll down to the Privacy or Security section. If your version of the software supports this feature, you'll see Hide Contacts, and when you activate it, you can select numbers that will only be available after you enter your password or fingerprint.
⚠️ Attention: New versions of HyperOS and new builds MIUI 14 this feature may be missing or moved to the Second Space settings. Don't look for it blindly if the interface is updated.
If the standard security menu doesn’t offer this option, it means that the manufacturer has removed it from your regional firmware version, in which case you should not try to “pull out” hidden features through the engineering menu, as this can lead to unstable operation of the system application “Phone”.
Why did the concealment function disappear?
The Second Space Method for Total Isolation
The most effective way to hide your contacts on Xiaomi is to use the “Second Space” feature, which is not just hiding, but creating a full-fledged second profile inside a smartphone that has its own separate desktop, its own apps and, most importantly, its own separate phone book.
To activate this feature, go to Settings → Second Space → Enable. The system will prompt you to create a separate password or use a different fingerprint to log into the second space. After switching, you will be in a clean interface where you can install the Contacts app and save all secret numbers there.
The advantage of this method is that the contacts from the Second Space are completely invisible in the main profile, and even if someone accesses your main screen and opens a contact search, they won't find numbers stored in an isolated environment, which is ideal for separating work and personal calls.
- 🔒 Complete data isolation: contacts are only visible after fingerprinting.
- 📱 Separate Notifications: Calls in the second space aren't bothered mostly.
- ⚙️ Flexibility: You can install different wallpapers and sets of applications.
The only downside is that it takes a couple of seconds to switch between spaces, and the notifications from the second profile may not come while you're mostly there, unless exceptions are set up, but for maximum privacy tasks, this is the best standard solution.
Third-party applications for hiding numbers
If the built-in MIUI isn’t good for you, Google Play apps come to the rescue. There are many “storage” programs that masquerade as calculators, voice recorders or flashlights, but have a password-protected section for contacts, photos and videos inside.
Popular solutions like Calculator Vault, Hide Contacts or Private Safe are import-based, so you don't move the contact from the system ledger (which could disrupt the call), you create a copy of it inside the app, and you can remove the original contact from the main ledger or just ignore it.
When installing this software, carefully read permissions. To operate the call function through a hidden contact, the application will need access to your phone book and call rights. This is a necessary trade-off: for the application to dial a number, it must have access to the communication module.
⚠️ Warning: Be careful with free versions of these apps, some of which may collect statistics or display ads, and choose programs that are highly rated and have a lot of installations.
Using third-party software gives more customization options, such as setting a pin code other than the screen unlock code, or setting up an “alarm button” that makes hidden data visible when you enter a password incorrectly.

💡
The most reliable way to hide contacts on Xiaomi without installing questionable software is to use the “Second Space” feature, which creates an isolated environment with a separate phone book.
To sum up, it depends on your goals: for quick “masking” from children, a display filter or Second Space will suit. For serious protection of personal data, it is better to use specialized applications with encryption. Remember that no method gives a 100% guarantee if the device physically falls into the hands of an attacker with the screen on, so always use a screen lock.
