Situations when there is a need to make an anonymous call occur in the life of every smartphone owner. Whether it’s business negotiations where you need to maintain the confidentiality of personal contact, or trying to protect yourself from callbacks after selling an item on a bulletin board. The operator Yota, being part of the ecosystem Tele2, provides its subscribers with several mechanisms for managing caller ID, however, in practice, users often encounter difficulties in setting up this function on devices under control Android.
The problem of hiding your Caller ID is not always solved with one simple button in the menu, since the settings can be covered by system restrictions of the operating system or tariff conditions. It's important to understand that there is a difference between temporarily hiding for one call and permanent incognito mode for all outgoing connections. In this material, we will analyze in detail all available methods, from standard USSD requests to deep settings in the interface of your gadget.
Before you start changing parameters, it is worth noting that some methods may be paid or require prior activation of the service from your telecom operator. In addition, the effectiveness of the method depends on the model of your device and the firmware version, since the interfaces Samsung One UI, Xiaomi MIUI and clean Android may differ in the location of menu items. Completely hiding a number does not guarantee 100% anonymity before intelligence services or a telecom operator, but effectively hides the data of other subscribers.
Using USSD codes for temporary hiding
The fastest and most universal way to hide your number when making a specific call is to use a special prefix before the dialed number. This method works at the network level and does not require deep diving into the phone's settings, making it ideal for one-off use cases. You do not need to change the configuration of your smartphone or wait for services to be activated; you just need to enter a combination of numbers in the dialing field.
For subscribers Yota and most Big Four operators in Russia, the standard European code applies. To hide the number for the current call, you must enter a sequence of characters #31# immediately before the recipient's number. For example, if you need to call the number 89991234567, then in the dialing line it will look like #31#89991234567. After pressing the call button, the network will process the request and hide your ID.
There are also alternative codes that may work depending on the roaming settings or the specific operator gateway to which your phone is connected. Sometimes a star is used instead of a hash, although this is less common. If the basic code does not work, you can try variations, but in 95% of cases the standard combination is effective.
⚠️ Attention: Make sure that you enter the code before the number without spaces. If after dialing you hear beeps, but the subscriber sees your number, the recipient may have a paid service called Anti-Identifier, which forcibly displays the numbers of hidden subscribers.
This method is especially convenient when you need to maintain anonymity for only one contact, and leave the number open for other calls. You won't have to change the settings back every time, which saves time and reduces the risk of forgetting to turn the number display back on.
If code #31# doesn't work, try adding a pause. In some cases, entering a code, waiting for a dial tone and only then dialing the main number helps, although modern networks process the request instantly.
Permanently hiding a number through Android settings
If your goal is to make the number hidden by default for all outgoing calls, you will need to change the settings in the menu of the smartphone itself. The operating system Android allows you to manage Caller ID settings directly through the Phone application, however, the path to these settings may vary depending on the device manufacturer and OS version.
In most standard interfaces, such as on smartphones Pixel, Nokia or Motorola, the algorithm of actions is as follows. First you need to open the calling application, then click on the three dots in the corner of the screen to open the menu and select “Settings”. Next, you should find the “Accounts” or “Advanced Settings” section, where the desired parameter is hidden.
- 📱 Open the “Phone” application (green handset).
- ⚙️ Go to the settings menu (three dots or gear).
- 🔍 Find the “Advanced Settings” section or “Operator Services”.
- 👤 Select “Caller ID”.
- 🚫 Set the value to “Hide number”.
On devices from Samsung with shell One UI path may be a little different. There you often need to go to the general settings of the smartphone itself, find the “Applications” section, select “Phone” and then look for additional call settings inside it. In some firmware versions, this item may be called “Show my number.”
It is important to consider that after selecting the “Hide number” option, the phone will send a request to the operator’s network to activate the service. This process may take from a few seconds to a minute. If you see an error message or the setting immediately returns to its original state, this may mean that your tariff plan does not support this function or it is blocked on the side Yota.
Service activation “Caller ID” from Yota
Unlike temporary hiding through codes, permanent setup through the phone menu often requires connecting the corresponding service on the operator’s side. U Yota this function may be called “Caller Identifier” or be part of advanced communication packages. Without an active subscription, the network may ignore your phone's requests to hide the identifier.
You can check the connection status and activate the service through your personal account on the operator's website or in the mobile application My Yota. This is the most reliable method, as it ensures that blocking occurs at the switch level, and does not simply depend on the settings of your gadget. In the application, you need to find the “Services” or “Communication Settings” section and look for an option related to privacy.
It is worth noting that this service may be paid. Operator tariffs change, and what was free a year ago may today cost a certain amount per day or month. Therefore, before activating through the app, carefully read the terms of service.
⚠️ Attention: Tariffing conditions and service availability may change. Be sure to check the current conditions in the official application of the operator or on the website, as the rules may differ for different regions and tariff plans.
If the application does not have an explicit button for connecting, you can use a USSD request to manage services. Often, to activate hiding a number, a code *112# or similar is used, the menu of which will prompt you to select the necessary options. However, there may not be a universal code for all regions, so the personal account remains a priority channel.
After successfully connecting to the service, you will receive a confirmation SMS notification. From this moment on, all your outgoing calls will be displayed to subscribers as “Unknown number” or “Private number”, regardless of the settings of the phone itself.
☑️ Checking the service connection
Specific settings on different smartphone models
The variety of Android devices leads to the fact that standard configuration paths can be changed by manufacturers. Owners of popular brands are often faced with unique interfaces where the necessary parameters are hidden in unexpected places. Understanding the logic of a specific manufacturer will help you quickly find the required function.
On smartphones Xiaomi, Redmi and Poco with a shell MIUI or HyperOS call settings are often integrated into the system "Security" application or have a separate menu in "Phone." Sometimes you need to switch to the "SIM Card Settings" mode to see the option to display the number. If the standard path does not work, try using the search in the settings by entering the phrase “number” or “caller”.
Devices Huawei and Honor with a shell EMUI also have their own characteristics. There, the path often lies through “Settings” -> “All” -> “Calls” -> “Advanced”. In some firmware versions, the option may be hidden if there is no SIM card inserted into the phone or if airplane mode is activated.
Below is a table summarizing the approximate paths for popular brands, which will help you navigate the maze of menus:
| Brand / Shell | Path to settings | Nuances |
|---|---|---|
| Samsung (One UI) | Phone → 3 points → Settings → Additional | May require a reboot |
| Xiaomi (MIUI) | Phone → Settings → Accounts / SIM | Often hidden in a submenu |
| Huawei (EMUI) | Settings → All → Calls → Advanced | Depends on Android version |
| Pixel / Motorola | Phone → Settings → Calls → Advanced | Android standard path |
If you can't find the setting in any of the places listed, it may be your carrier blocks the ability to change this parameter at the device level, requiring the connection of a paid service. In this case, changing the phone settings will not work without operator intervention.
What to do if the “Hide number” item is not in the menu?
If the phone menu does not have the option to change Caller ID, this means that the device manufacturer or telecom operator has limited this function. Try using USSD codes or contact Yota support to connect the service on the network side.
Third-party applications and their limitations
In the store Google Play you can find many applications that promise to hide the number or make an anonymous call. However, users must understand the technical limitations of the operating system Android. Applications do not have the right to directly control the communication module to spoof or hide an identifier without root access, since this is a network level function.
Most of these applications work on the principle of a “proxy call”: you call through the app server, it connects to the subscriber, and he sees the server number or hidden number. This is often a paid service, requires stable internet and may have a delay in establishing a connection. In addition, such methods may arouse suspicion among the telecom operator.
Using third-party software for these purposes carries certain risks. You trust your conversations to third parties, which contradicts the very idea of privacy. In addition, many “secret” apps contain advertising or collect contact data.
- 🛑 Don't trust apps that require root access to hide your number.
- 💸 Be prepared for the fact that the service may be paid.
- 📶 To operate such applications, you often need the Internet (VoIP).
The most secure and effective method remains the use of built-in Android functions or operator services Yota. This guarantees stable communication and the absence of unnecessary software in your phone that could slow down the system.
Third-party applications for hiding your number are often less reliable and secure than standard phone settings or operator services.
Possible problems and ways to solve them
Even if all instructions are followed, users may encounter with situations where the number continues to be displayed. This may be caused by technical failures, tariff features, or actions of the subscriber himself. Understanding the reasons will help you quickly troubleshoot problems.
One of the common reasons is a settings conflict. For example, if you have “Hide number” set in your phone, but in your personal account Yota the “Anti-identifier” service is disabled or, conversely, the “Open number” service with priority is activated. The network always takes precedence over the phone settings, so check the service status in the operator's application.
Also, the problem may occur when calling short numbers or emergency response services (102, 103, 112). In these cases, hiding the number is technically impossible and prohibited by law. Your number will always be identified by the emergency operator.
⚠️ Attention: If you change your phone or SIM card, your number hiding settings may be reset. Always check that the settings are up to date after replacing equipment or moving to another region.
If all else fails, try rebooting the device. This will update your online registration and apply the new settings. As a last resort, you can remove the SIM card, wipe the contacts and insert it back to initiate a complete reconnection to the network Yota.
Why is the number seen if the service is connected?
This can happen if you call a subscriber who has the Anti-Anti-Identifier service activated. It allows you to see the numbers even of those who hide them. In this case, it is technically impossible to hide the number.
