Owners of Xiaomi smartphones often face a situation when it is urgent to know their own mobile phone number. SIM-Unlike button phones, where the number is often displayed on the greeting screen, modern Android shells require certain actions to display this information. Knowing where to look for this data will save you time and nerves.
There are several proven ways to get this information, ranging from standard system settings to special engineering codes. The MIUI or HyperOS shell provides users with flexible communication profile management tools. However, the location of the menu items may vary depending on the operating system version and regional firmware of the device. Below we will discuss each method in detail so that you can choose the most convenient one.
It is important to note that the correct determination of the number depends not only on the settings of the smartphone, but also on the actions of the operator. SIM-The card is new or has been recently replaced, the system may not have had time to read the data from the chip, in which case the automatic methods may not work, and you will have to resort to manual input or call.
Checking the number through system settings
The most reliable and secure way to find your number is to access the system settings menu. Xiaomi interface is structured logically, but the names of items can vary. You need to open the main menu and find the gear icon. Next, the path will depend on the version of MIUI installed on your device. In most current firmware, the algorithm of actions is unified for the convenience of users.
Once you enter the settings menu, you should find the section that handles networking, usually called "About the Phone" or "About the Phone «SIM-This is where all the technical information about the connected communication modules is stored. The system reads the data directly from the chip. SIM-card or profile stored in the device memory. If the operator has transmitted correct data when registering on the network, the number will appear in the appropriate field.
⚠️ Note: If the Phone Number field displays zeros or a set of characters "Unknown", this means that SIM-The card didn't send the number to the phone book of the device, so the system method won't work, so you have to use other options.

The number can only be displayed for one of the cards if the second one is not active or has no coverage. Make sure that the card activation slider is translated into the "On" position.
☑️ Checking in settings
Use of the USSD-operator
A universal method that works on any mobile device, regardless of the model and firmware version, is the use of USSD-These commands are sent directly to the carrier's server, which instantly returns the requested information, which is the fastest way, without requiring Internet access or deep immersion in the smartphone menu. Every major telecommunications company has its own unique number check code.
To complete the request, open the Phone app and go to the dial bar. Enter the combination of numbers and characters corresponding to your operator and press the call button. The answer will come in the form of a pop-up window or SMS-Below is a table with the most common commands for Russian operators, which are often used in Xiaomi devices.
| Operator. | USSD-team | Format of response |
|---|---|---|
| MTS | *111# or *100# | Pop-up menu |
| MegaFon | *105# | A pop-up window |
| Beeline | *110*10# | SMS or screen |
| Tele2 | *155# | Pop-up menu |
| Yota | *100# | Information window |
Once you type in a command, you may see a menu with different services on the screen, and you may need to select "Check the number" or the same, following the instructions on the screen. Sometimes the answer comes in the form of an incoming one, rather than an instantaneous one. SMS. Make sure you have a minimum balance on your account, although most often this service is free. USSD-The requests work even if there is no mobile Internet.
What to do if the team is not working?
Calling another phone
The most obvious, but sometimes forgotten, method is a simple call: If there's another phone or landline nearby, you can just call it from your Xiaomi, and your number will be displayed on the screen of the receiving device. This method guarantees 100% accuracy, as the number is broadcast through the operator’s networks in real time, and is especially relevant if the settings of the smartphone are lost or if the phone is not installed.

The path to setting up is usually: Phone → Settings → Accounts for → Additional settings → call ID. Here you should select “Show number”.
If you don't have another phone on hand, you can use online services or instant messengers, such as sending a WhatsApp or Telegram message to your favorites contact or asking a friend to dictate a number they have chosen, and calling your carrier's toll-free service number, where an automatic voice assistant often greets the caller by calling their number.
💡
Use messengers: If you can't call, open Telegram and send a message to Favorites. In some cases, the number may pull up from your profile if it's listed there, or you can see how others see you.
Engineering menu and hidden Android codes
For more advanced users, there is a way to get detailed technical information through the engineering menu, which is a hidden part of the system, designed to test equipment and diagnose networks. In Xiaomi devices, access to it is often closed or requires special rights, but the basic Android codes work on most models, through which you can see not only the number, but also the signal level, network type and IMEI.
To get into the test menu, open the dialer and enter the code ##4636##. If the code is entered correctly, the menu will open automatically, you do not need to press the call button. In the list that opens, select Phone Information. This may display a number, but on modern versions of MIUI this line is often hidden for security purposes or filled with zeros.
⚠️ Warning: Be extremely careful in the engineering menu. Changing settings in the "Set preferred network type" or other technical fields can lead to loss of communication or modem malfunction.
There are other codes that can be useful:
- 🔧 *#06# - displays IMEI and IMEI SV (equipment identifiers).
- 📡 ##3646633## - Entrance to the full engineering menu (not working on all firmware).
- 📶 ##4636## - Testing menu (main method).
If standard codes don’t open the menu, your firmware may be limiting this functionality, so you can try installing a third-party IMEI checker or engineering menu from the Google Play store, although newer versions of Android also have limited access.
Definition through applications and messengers
The digital ecosystem today is closely linked to your phone number, and many of the apps that are installed on Xiaomi already have access to that data or can display it in a user profile, a convenient way to find out if you forget it but use your smartphone regularly, most often stored in instant messengers, social networks or Google accounts.

Also, the number is often saved in your Google account. Go to your phone settings, select Google» → «Go to the Personal Information tab, if a number was added during registration or restoration of an account, it will be listed there.

What to do if the number is not determined
The situation where Xiaomi smartphone does not see the phone number is quite common.This can be due to damage to contacts. SIM-If none of these methods worked, and the settings are zero, you need to do a diagnostic, and often the problem is solved by simply cleaning the contacts or replacing the SIM with a new one in the operator's cabin.
Try to get it out. SIM-If you have a two-sym phone, you can move the card to another slot, and you can wipe it with a soft dry cloth, and you can put it back in, make sure it's sitting tight in the tray, and if you have a two-sym phone, you can try to move it to another slot, and that will help you to avoid the malfunction of the reader in the smartphone, and it's worth checking if the card is on the card.
