How to Make a Hidden Number on Xiaomi: The Complete Guide

Xiaomi’s modern smartphone is not just a means of communication, but a complex system that stores a lot of sensitive information. Device owners often face the need to hide their number when making outgoing calls, whether for privacy or business etiquette. A hidden number allows you to call anonymously, showing the recipient as “Unknown number” or “Anonymous”.

There are several layers of privacy settings in Android, which runs the MIUI shell, some of which work at the carrier level, others work directly in the smartphone settings, and it's important to understand the difference between temporary concealment and constant setup so you don't lose control of outbound traffic.

In this article, we will take a look at all the ways you can use, from standard phone settings to engineering codes, and learn how to manage your online visibility and quickly switch between open and hidden call modes, a knowledge that is essential for any user who values their privacy.

Standard Call Settings in MIUI

The easiest and safest way to hide a subscriber's ID is to use the phonebook's built-in functionality. In current versions of the MIUI shell, the path to this setup may vary slightly, but the logic remains the same for most models. You don't need to install third-party apps or obtain superuser rights.

To start, open the standard Phone app and go to the settings menu, usually indicated by three dots or a gear in the corner of the screen, find the account and sync section, or immediately go to "Advanced." That's where the option is hidden.

In the optional settings menu, you need to find the option "Display Number" and the system will offer you three options: "Show Number", "Hide Number" and "Network Settings", the choice of the third option will transfer control of the SIM card to the operator, but often works and direct choice of the second option.

• 📱 Open the Phone app and click on the settings menu.
• 🔍 Go to the section "Accounts and synchronization" or "Additional".
• 🛑 Select the option "Display Number" and set the value "Hide Number".
• ✅ Wait for confirmation from the network operator.

⚠️ Note: If after selecting the option "Hide number" there is an error or setting is immediately reset, then your operator prohibits this action at the tariff level.

It is worth noting that on some global versions of Xiaomi firmware, the interface may not be fully translated, and menu items will be called differently.Look for keywords such as "Caller ID", "Show my number" or "Additional settings". Global firmware often differs from the Chinese version, so the location of items can vary.

Use of the USSD-number-code

If the smartphone menu does not give the desired result, come to the rescue USSD-These are special commands that go directly to the operator's server and change the SIM card settings, and this method is universal and works on almost all devices, regardless of the version of Android or phone model.

To activate the number antideterminer (AND) mode, you need to enter a special combination of characters in the dialing field. After entering the code and pressing the call button, you will receive a response message from the network. Successful activation is confirmed by the corresponding text notification.

#31#phone number

This code allows you to hide the number for a particular outgoing call, and if you have to hide the number for all calls, you use a different command, but there is no universal code for all operators, and each provider has its own rules.

• 📞 For one-time concealment, dial #31# before the subscriber number.
• 🔒 For permanent concealment, use the activation code of the service (depending on the operator).
• 🔄 To cancel the concealment, dial the appropriate deactivation code.
• 📲 Check the status of the service through the menu "My operator" or personal account.

Some operators require an additional service called AntiAON or similar, and without an active service on the provider side, commands from the phone may not be executed or return an error.

Engineering menu and hidden Android settings

For advanced users, there's an engineering menu, a hidden part of the system that's designed to test hardware and configure network settings, and you can access it with special codes that give you access to the deep settings of the radio module.

Type ##4636## into the dialer. If your device supports this command, the Testing menu will open. Here you need to select the "Phone information" section. In the list of options, look for the option associated with Caller ID. Changing the settings here requires caution.

The changes to the engineering menu take effect immediately, but after the device is rebooted, the settings may reset to factory ones. The engineering menu is not available on all Xiaomi models, as manufacturers often block this access in global firmware for security reasons.

Specifics of working with different communication operators

The success of a number-hiding operation depends on the policy of your carrier: in Russia and CIS countries, large providers have their own names for the number-hiding service, for example, one operator may have an “Anti-AON”, another – “Hidden Number”.

To activate a service, you often need to send an SMS or use the operator's mobile application. In your personal account on the site, you can also find a service management section where it is easy to switch the status of the display number, which is the most reliable way to guarantee the result.

• 📱 MTS: Anti-AON service, activated via the application or USSD.
• 📡 Beeline: Anti-AON service, available in your personal account.
• 🌐 Megaphone: Hidden number service, management through the menu.
• 🔵 Tele2: Service "AntiAON", connected by code or in the application.

Remember that even when the function is on, the emergency services (112, 102, 103) always see your number, a legal and security requirement that cannot be circumvented by software methods, and the operator must transmit the coordinates and number when calling the emergency services.

💡

Use a second call app (like Google Phone) if the standard Xiaomi caller doesn’t save the number hiding settings after the reboot.

Problems and their solution in setting up

Users often experience a situation where settings are reset by themselves, which can be caused by a MIUI update or a software conflict. If the number is no longer hidden, try re-setting through the phone menu.

Another common problem is "Network is not available" or a login error when you turn on the number hiding, in which case switching the network mode helps. Try temporarily select only 2G/3G, activate the hide, and then return the "LTE/4G preferably" mode.

⚠️ Note: If you use VoLTE (calls through the phone) 4G), The number hiding function may not work properly. Try temporarily disabling VoLTE in the SIM card settings to check.

In some cases, resetting your network settings helps, and it won't delete your contacts or photos, but it will return all your connection settings to factory values, and then you'll have to re-enter your Wi-Fi passwords, but the problem with displaying the number often disappears.

Alternative methods of anonymous communication

If standard methods don't work or you need temporary anonymity, you can use alternative methods. There are also some identifiers that have a VoIP call function, and in this case, the subscriber sees a service number or a random set of digits.

You can also purchase an additional SIM card, issued without a passport (if the law in your region allows at the time of purchase), or to another person, and use it exclusively for anonymous calls, a “iron” method that cannot be blocked software.

Messengers (Telegram, WhatsApp, Viber) allow you to hide a number if the person you are talking to does not have your contact in the phone book, provided that you configure privacy in the "Who sees my number" section, which is a modern analogue of a hidden number for data transfer.

💡

The most reliable way to hide the number is to activate the service from the operator, since the phone settings only send a request to implement this function on the network.
