How to see Xiaomi phone number: full instructions

Owning a modern smartphone means constant communication, but sometimes even at the most inopportune moment we forget our own number, which must be urgently dictated. POCO Often, the interface is MIUI HyperOS hides this information in different places, especially if it is not a new one. SIM-The card was recently installed or transferred from another device.

There are several proven methods to instantly find out your SIM card data without having to go through a paper contract with the operator or waiting for a call from a friend. In this article, we will discuss in detail the regular system tools, hidden engineering menus and alternative ways that are guaranteed to help you in any situation.

No matter which version of the operating system you have installed on your gadget, the algorithms of actions remain similar, although the names of menu items may vary slightly depending on the regional firmware. SIM-cards, which is especially important for owners of two-symbol models.

Use of the regular settings menu SIM-map

The most reliable and secure way to find out your SIM data is to access system settings, where Android reads information directly from the chip. In Xiaomi shells, this section is as detailed as possible and allows you to manage both slots independently of each other, giving full access to technical data.

To start, you need to open the main app menu and find the Settings icon, which usually looks like a gear, then go to the About Phone section, which is often at the top of the list or in the System category, and then select the item. SIM-Maps and mobile networks. This is where all the key information about the connected operators is displayed.

In the window that opens, you will see a list of active SIM cards, where the full phone number will be listed under the operator name (for example, MTS, Beeline, Tele2). If the SIM card is not defined by the system or if the numbers are displayed “Unknown”, you may need to restart the device or clean the contacts of the metal chip.

💡

If the number does not appear in the settings, try to extract SIM-map, wipe the contacts with a soft cloth and insert back until the characteristic click.

It is worth noting that in some cases, especially when using old SIM cards or virtual mobile operators, the number field can remain empty even if there is a stable network signal, which is a technical feature of writing data to a chip, not a smartphone error, so in this situation you will have to use alternative methods.

Checking through the “Security” application

A unique feature of the Xiaomi ecosystem is the pre-installed system application Security, which combines the functions of antivirus, cleaner and device manager. Inside this application, a useful module is hidden that allows you to quickly (check) the status of SIM cards and find out the number without deep immersion in the system settings.

Run a green icon with a shield on your desktop, then scroll down to the Tools or Network block. You are interested in the SIM or SIM Management item, where the widget displays balance, traffic and, most importantly, the phone number associated with each slot.

The advantage of this method is that information here is often updated in real time through requests to the operator, which allows you to see the current data even if it is not in the standard menu, and from here you can quickly move to adjusting the tariff and traffic limits.

• 📱 Open the Security app on the desktop.
• 📶 Select the SIM card menu item in the bottom tool block.
• 👁️ Find the “phone number” line under your operator icon.
• 🔄 If necessary, click on the data update button for synchronization.

It is important to understand that the widgets in the Security app require an active Internet connection, since some of the data is downloaded from the MIUI servers. If you are in an uncoated area, the system may show data from the cache that may not be relevant after replacing the SIM card.

Use of the USSD-codes and engineering menus

For advanced users who need access to more in-depth technical information, there are special features for the user. USSD-These character combinations send a direct request to the operator's server or to the phone's modem module, returning a response in text or a special interface.

The easiest way to do this is to type in a universal code #1# or #100# (the code may vary between operators), which often displays basic subscriber information, but a more reliable method is to type in the command ##4636##, which opens the hidden test menu of the phone.

##4636##

Once you enter this combination, the screen will automatically switch to the Testing menu, where you need to select Phone Information. In the technical options list that opens, scroll down to the “My Phone Number” line, which will display your number read directly from the network register.

⚠️ Note: Do not change the radio settings or preferred network type in the engineering menu unless you understand their purpose, as this may cause a temporary loss of signal.

Note that on newer versions of Android (11, 12, 13 and above), access to some of the engineering menu items may be restricted by the manufacturer for security reasons. If the code does not work or the menu does not open, use standard settings or refer to the SIM card.

What to do if the number is written “Unknown”

When a phone number is labeled “Unknown” or the field is completely empty, it is quite common and usually does not indicate a device breakdown, the problem is that carriers have stopped writing the number directly to the SIM card chip at release, relying on automatic detection by the network.

The smartphone reads data from the SIM card memory, and if the cell is empty, it honestly tells the user about it, even though calls and the Internet work properly, which is standard behavior for most modern data plans released in the last 5-7 years.

In this case, you should not panic or carry the phone to the service, since it is impossible to “write” the number to the SIM card through the phone settings. You will have to use one of the workarounds that do not require access to the chip memory.

• 📞 Call or send. SMS to another phone to see your number in the call log of the interlocutor.
• 🌐 Go to the operator’s personal application (My MTS, My Beeline, etc.), where the number is always displayed on the main screen.
• 📦 Look at the plastic card from which you broke the SIM card, if it survived.
• 📄 Find a purchase agreement or check if the SIM card was officially registered with you.

It’s also worth checking if a third-party call manager is installed on the phone, which may not display system information correctly.Switching to a standard “caller” from Google or Xiaomi often solves the visual display problem.

Comparison of methods of obtaining information

For the convenience of users, we have systematized all the methods considered in a single table so that you can quickly choose the most suitable option depending on your situation and availability of Internet access or a second SIM card.

As you can see from the table, the most versatile method is to call another device, because it works even when the phone's settings are completely down, but for quick checks without unnecessary action, the standard settings of the MIUI system are best suited.

💡

The most accurate information is always provided by the operator’s network, so a call or a personal account are the reference data sources.

Nuances of working with two SIM-map

Xiaomi smartphone owners often use two numbers at the same time, and it is important not to confuse which one is recorded in which slot.In the settings interface, the slots are designated as SIM 1 and SIM 2, and visually they can differ in the color of the icon or the location in the list.

To accurately identify SIM cards, you can temporarily turn one of them off in the settings menu, leaving only the desired slot active. After that, any verification method will show the number of only the active SIM card, which will eliminate confusion when recording contacts or configuring messengers.

HyperOS also has the ability to give SIM cards custom names, such as “Work” or “Personal”, and by renaming them, you will see these tags in all system notifications, which will greatly simplify navigation.

Remember that when you have active call standby on two SIM cards, the number from which the outbound call is made depends on your default settings. You can check and change the priority number for calls in the Settings → SIM cards and mobile networks → Default for calls.
