The situation when you urgently need to know your own phone number, occurs to owners of Xiaomi smartphones quite often. SIM-Unlike older button phones, where the number was often pasted on a battery, modern Xiaomi smartphones with fixed batteries require software methods to obtain this information.
Operating system MIUI And Android has a few built-in tools to display subscriber data, but depending on the firmware version, the device's regional binding, or the carrier's, the methods may vary. SIM-maps that require the use of alternative methods.
In this article, we will discuss in detail all the current methods, ranging from the standard settings menu and ending with special ones. USSD-We'll also look at the nuances of working with two. SIM-We can explain why in some cases the system writes "Unknown".
Checking the number through the MIUI system settings
The most obvious and secure way to know your number on a Xiaomi device is to access the built-in settings menu. MIUI It's designed so that the user can easily manage the communication settings, and you need to open the Settings app and find the section that's responsible for the work. SIM-map.
The path to information may vary slightly depending on the version of the operating system. In most current assemblies, the algorithm of actions is as follows:
- 📱 Open the main menu and launch the Settings app.
- 📡 Find and select the item About the phone or SIM-maps and mobile networks.
- 🔢 Click on the image or name you want. SIM-map (SIM 1 SIM 2).
The carrier window that opens should show your phone number, and if the field is empty or contains dashing, it means that the system failed to read the data directly from the chip.
⚠️ Note: If the settings menu does not show the number, do not rush to restart the device. Often the problem lies in the format of recording the contact on the device itself. SIM-map, not a smartphone software failure.
Importantly, some global firmware versions may have a deeper path to hide, so try searching by settings: click on the magnifying glass at the top of the settings screen and type in the word "SIM." The system will prompt you to go to the desired section where network settings are displayed.
Use of the USSD-number-code
If software methods do not give results, universal methods come to the rescue. USSD-These are special combinations of characters that are sent to the server of the mobile operator. SMS It works regardless of the phone model, whether it’s a budget Redmi or a flagship Xiaomi.
Each carrier uses its own unique combinations, and below is a table with codes for major Russian operators that are relevant to users of Xiaomi equipment:
| Operator. | USSD-code | The result |
|---|---|---|
| MTS | *100# or *100*0# | Pop-up window with number |
| Beeline | *110*10# | SMS-message |
| MegaFon | *558# or *558*0# | A pop-up window |
| Tele2 | *200# or *200*1# | A pop-up window |
| Yota | *103# | SMS-message |
To complete the request, open the Phone app (green handset) and dial the appropriate combination, then press the call button. Check the tariff plan if in doubt.
⚠️ Attention: When in use USSD-codes, make sure that SIM-The card you're sending the request from is active and has a network signal. 4G/LTE" Without VoLTE support, some old codes may not be handled correctly.
There are also common codes that can work across different operators, such as *2# or *199#. However, their effectiveness is lower than that of the specialized commands listed in the table above. If one code fails, try the next one from the list.
💡
Save it. USSD-Your operator's code in notes or make a contact in a phone book with the name "My number" so you don't search for it every time.
Determination of the number through calls and messages
When settings are hidden and codes are not working, the easiest way to call or text another subscriber is to call or text another subscriber, which requires no technical knowledge and works on 100% of devices, including the old Redmi Note series models or the new Xiaomi 13/14.
You can call a friend's phone, a relative's phone, or your second cell phone, and the number will show up on the screen of the receiving device, and if you don't have another phone, you can send it to the host. SMS-To do this, enter your number in the recipient field (if you know it partially), or select the contact "I" (if it is created), or simply send a message to any other phone.
Another option is to use instant messengers, if Telegram, WhatsApp or Viber are installed on a smartphone and an account in them is already registered to this service. SIM-map:
- 📲 Open the profile settings in the messenger.
- 👤 Click on the avatar or username.
- 📞 In the "Information" section or under the name will be indicated the associated phone number.
This method is especially convenient, since it does not require a second device or minutes / messages of the tariff plan.
However, you should consider (privacy): If you hide your number through the operator settings (definition), then when you call some phones you can define yourself as "Unknown number" or "Hidden number", in which case the method with messengers will be more reliable.

Working with two SIM-maps on Xiaomi
Xiaomi smartphones are famous for their support of two SIM-This creates some nuances when determining numbers, and users often confuse which card is being called from or which card the account is registered to. MIUI A convenient visual separation system is implemented.
In the settings SIM-You can see two separate tabs or cards, each of which is colored (usually orange and blue) and you can click on each of them and you can see the number information if it's read. If you insert two cards from different operators, the methods are: USSD They will be different for each of them.
To control the behavior of two cards, use the following settings:
- 📞 Calls: Select "Always Ask" or assign a primary call SIM-default-card.
- 💬 Messages: Similarly, you can set a priority card to send SMS.
- 🌐 Internet: Make sure that mobile internet is enabled on the map where there is traffic so that the codes of operators work correctly.
It is important to set up the names correctly. SIM-In the settings menu of each SIM there is a field "Name" SIM-Rename them, for example, "Worker" and "Personal" or enter the numbers in full, which will allow you to instantly active card in the top status bar.
⚠️ Attention: When actively transmitting data (4G/5G) one-on-one SIM-The second card can be switched to the second. 2G/3G Temporarily shut down (depending on the technology) DSDS). If the code *100# It does not work, try to temporarily turn off the mobile Internet or switch it to another SIM.

Why the number is not displayed: reasons and solutions
Quite often, users are faced with a situation where the "Phone Number" column is marked with the words "Unknown" or the field is empty. This is a common problem that is not a defect of the Xiaomi smartphone — SIM-map.
When you issue a card, carriers don't always write a number to a special memory field on the chip (MSISDN field), and if that cell is empty, the phone can't physically read the number because it has nowhere to get it, especially for cards that were released a few years ago or for corporate rates.
To correct the situation, you can try the following actions:
- Extract. SIM-map and gently wipe the contacts with a soft cloth.
- Put the card in another phone (preferably Android) and try to see the number there, and if there is one, the problem is in the map.
- Use it. USSD-The codes described above, as they request a number from the network, not from the chip.
If the number is critical to display in the menu, the only solution is to replace it. SIM-The phone number will be retained, and the new card will likely have the number field filled in correctly.
It's also worth checking if your phone has a third-party theme, and some custom MIUI themes may not display system fonts correctly or hide certain fields in the settings menu, and switch to the standard "Classic" or "Untitled" theme to check.

The absence of a number in the settings is not a breakdown of the phone, but a feature of recording data on a specific SIM-Use the map. USSD-quick-fix code.
Additional methods and expert advice
There are less obvious ways to get information about the number, which can be useful in specific situations, for example, if the phone is new and if the phone is not available. SIM-The card just activated, the number is often printed on a plastic basis, from which you squeezed the chip.
The number can also be found in the contract with the operator, if it is saved in paper or electronic form. For virtual operators and eSIM, the information is always available in the operator's mobile application in the "Profile" or "My data" section.
For advanced users familiar with the Android engineering menu, there is a technical way to view information:
##4636##If you type this command in the call, you can go to the test menu. If you select "Phone Information," you can see the technical parameters of the network. SIM-So if it's empty in the settings, it's probably empty here, too.
Use the *#06# command to receive only IMEI-Device code. Many users confuse these concepts. IMEI — This is a unique identifier for Xiaomi's device itself, not your SIM card. IMEI, You can find the phone model and its origin, but not the phone number.
