In the modern world, privacy is becoming an increasingly valuable resource, and there is often a need to hide your subscriber status from your interlocutor. A hidden number allows you to make calls without revealing personal information, which is convenient for business negotiations, calls to advertisements, or simply to protect yourself from unwanted attention. The operating system Android provides users with flexible tools for managing these settings directly in the device interface.
However, the process of hiding numbers may vary depending on smartphone modelsthe firmware version and even the conditions of your telecom operator. Sometimes the built-in options do not work, and then you have to resort to more complex methods, such as entering special commands or changing the SIM card configuration. Let's look at all the available methods so that you can choose the most suitable option for your situation.
It is important to understand that disabling the function does not always work: emergency services and some large organizations can see your Caller ID regardless of the settings. Additionally, if you are calling a landline, hiding may not work due to call routing features on older networks. Below we will look at the action algorithms in detail.
Standard call settings in the smartphone menu
The easiest way to hide your data when making a call is to use the built-in settings of the Phone application. This method does not require the installation of third-party software and works on most modern devices. You need to open the standard “dialer” and find the section responsible for additional communication options.
The interface may differ depending on which launcher or shell your gadget uses. In most cases, the path looks like this: open the menu, select Settings, then go to Additional Call Services or More. Here you will find the option Number identification.
Click on this item and the system will offer three options: “Show number”, “Hide number” and “Default settings”. Select mode "Hide number". If this item is inactive or disappears, it means that the telecom operator is blocking changing this option through the phone menu, and a different approach will be required.
⚠️ Attention: If the "Number Identification" item gives the error "Request not completed" or "Not supported by the network", this means that your cellular provider does not allow you to change this parameter yourself. In this case, you need to contact the operator's support.
It is worth noting that on some models Samsung or Xiaomi the menu may be hidden deeper. Sometimes you need to first select a specific SIM card, if there are two of them in the device, and only then look for identification settings. Do not forget to return to the initial state after completing anonymous calls so as not to miss important calls from colleagues.
Using USSD codes for quick hiding
If the settings menu does not give the desired result, you can use universal commands that are sent directly to the operator’s network. These USSD requests are the GSM standard and work on almost all devices, regardless of the Android version. This is a quick way to temporarily change your status.
For one-time hiding of a number before a specific call, a prefix is used. You need to dial the code, then the subscriber's number and press the call button. The most common command format looks like this:
#31#phone_numberFor example, if you want to call the number 89001234567, dial #31#89001234567. In this case, your Caller ID will be hidden only for this specific call, and will remain visible for all subsequent calls. This is convenient when you need to make just one anonymous call.
There are also codes for completely disabling or enabling the function on a permanent basis, but their operation depends on the tariff plan. Try entering the command #31# and press call - this is an attempt to globally hide the number. To return visibility, the code is usually used *31#.
If the code #31# does not work, try replacing it with *67# before the number. This format is often used in roaming or on specific tariffs of some operators.
Remember that entering commands must be accurate. An extra character or space may cause the request to fail. If, after entering the command, you see an error message on the network, it means that the service of hiding the number on your SIM card is not activated or blocked by the provider.
Contacting your telecom operator for permanent blocking
The most reliable way to permanently remove your number from the field of view of your interlocutors is to activate the service directly from the operator. Many providers offer the “Anti-AON” or “Hidden Number” option as a paid or free additional feature. This ensures that the setting is applied at the network level, and not just on the device.
The connection process may vary from company to company. This is often done through a personal account in a mobile application or on a website. You need to find the section with communication services and activate the corresponding item. In some cases, confirmation via SMS code is required.
- 📞 MegaFon: The Anti-Caller ID service is activated through an application or a command in your personal account.
- 📞 MTS: The "Anti-Caller ID" option is available in the communication services section.
- 📞 Beeline: Service "AntiAON" allows you to hide the number for outgoing calls.
- 📞 Tele2: Offers the "AntiAON" service for complete confidentiality.
Please note that with the active number hiding service, you yourself will not be able to see who is calling you if the interlocutor also has protection. This creates a “mirroring” situation where both subscribers remain anonymous to each other. Also, some services may block entry to personal bank accounts if the call comes from a hidden number.
⚠️ Attention: Activating the service with the operator may require a fee. Be sure to check the tariff conditions in your personal account before connecting to avoid unexpected debits from your account.
What to do if the operator refuses to connect?
Some corporate tariffs or special offers do not allow you to disable number identification. In this case, the only solution is to change the tariff plan to a standard one or use third-party dialer replacement applications that replace the data before sending it to the network, although the effectiveness of this method is lower.
Hide the number for a specific SIM card on dual-SIM devices
Owners of smartphones with support for two SIM cards often encounter confusion in the settings. It is important to understand that the caller ID parameters are tied to a specific SIM card, and not to the phone as a whole. You can set the number visibility for one SIM card, leaving the second open.
When making a call, the Android system always asks (or uses the default setting) which card to call from. Go to call settings and select the SIM card slot for which you want to change the settings. The algorithm of actions is similar to that described above: find the “Number identification” item for the selected slot.
If you use different SIM cards for work and personal purposes, it is logical to hide the number only on the work SIM card. This will allow you to maintain a professional distance without losing touch with friends and family on a personal line. Make sure that the switch in the settings menu is set to the correct position.
| Parameter | SIM card 1 (Work) | SIM card 2 (Personal) |
|---|---|---|
| Number status | Hidden | Displayed |
| Service type | AntiAON | Standard |
| Cost | Paid/Free | Free |
| Availability | Always | Always |
Do not forget to periodically check the settings, especially after updating the system. Sometimes resetting the network settings can return the settings to factory defaults, and your number will again become visible for all incoming and outgoing connections.
Caller ID settings are applied individually to each SIM card. Changing the setting for one slot does not affect the operation of the second slot.
Third-party applications for data substitution and protection
When standard methods do not work or require payment, applications from the store come to the rescue. Google Play. There are apps that act as an intermediate link: you call through an application, it connects to the server, and the server makes a call to the subscriber, replacing your number with a temporary or hidden one.
Such applications are often called “second numbers” or virtual PBXs. They allow you not only to hide your real number, but also to use an additional virtual number to register on websites or communicate with couriers. This increases the level of digital security and reduces the amount of spam.
However, this method has its drawbacks. Firstly, the quality of communication may depend on the speed of the Internet, since the call is often made using VoIP technology. Secondly, most good services are paid or operate on a subscription basis. Free versions usually have limitations on call time.
- 🛡️ Privacy: The real number remains secret.
- 🌐 Network dependence: A stable Internet connection is required for the application to work.
- 💰 Cost: Payment for minutes or a subscription is often required.
- 📱 Convenience: No need to go into deep phone settings.
Before installing such software, carefully read the permissions that the application requests. Some apps may require access to contacts or call history, which in itself is a risk of data leakage. Choose only proven solutions with a high rating.
Possible problems and ways to solve them
Even if all instructions are followed correctly, situations may arise when the number is still displayed to the interlocutor. This may be due to technical features of the network or settings of the receiving party. For example, if a subscriber has installed a special caller ID (like Yandex or GetContact), he can see your name even if the number is hidden, using his databases.
Problems may also arise when calling abroad. In roaming, call routing rules are different, and hiding prefixes may be ignored by foreign operators. In this case, the only guaranteed way is to activate the service with your home provider before the trip.
If all else fails, try resetting your call settings. To do this, go to the settings of the “Phone” application, find the “Reset settings” or “Restore defaults” item. This will clear the error cache and return the menu to its original state, after which you can try to configure hiding again.
☑️ Diagnosing the problem of hiding a number
⚠️ Attention: Remember that it is impossible to be completely anonymous. Intelligence agencies and telecom operators always see your real number, regardless of your phone settings. Hiding a number only works for an ordinary subscriber on the other end of the line.
Frequently asked questions (FAQ)
Will the interlocutor see my number if I hid it in the settings?
In most cases, “Unknown number”, “Hidden number” will be written on the interlocutor’s phone screen or "Anonymous". However, if he has a third-party caller ID installed with an extensive database, he may see your name, but not the phone number itself.
Is it possible to hide a number for free?
Yes, using a USSD code #31# in front of the number is usually free. Also, many operators allow you to hide your number forever for free through the settings in your personal account, although some tariffs require a monthly fee for this option.
Why is the “Hide number” setting inactive (gray)?
This means that your telecom operator prohibits changing this parameter through the phone menu. You need to call support or go to the operator’s personal account to activate the AntiAON service there.
Will the number be visible when calling the police or ambulance?
No. Emergency services (102, 103, 112) always see the caller's number, even if it is hidden. This is necessary for quick location determination and feedback in a critical situation.
How to return the number display back?
Go to the call settings and select the “Show number” or “Default settings” option. If you used a USSD code, enter the command *31# and press call. If the service is connected to an operator, disable it in your personal account.
