Xiaomi Redmi 10 smartphone owners often face the need to quickly find out their own phone number directly from the device screen. This is especially true when you insert a new SIM card, change the operator or simply do not remember your number recorded in the contract. Unlike older button phones, where the number was often “sewn” on the plastic card itself, in modern smartphones this information is stored in a software profile that reads the MIUI or HyperOS operating system.
Understanding how to access this data is a basic skill for any Android device user. In Xiaomi Redmi 10, the search process can vary depending on the firmware version, the regional binding of the device, and even how many SIM cards are installed in the slot right now. Sometimes the system cannot automatically count the number, and then the user has to resort to manual input or use special devices. USSD-code.
In this article, we will take a closer look at all the ways you can get your SIM card number in your Redmi 10 settings. We will look at the standard interface tools, hidden engineering menus, and alternative methods that will help you, even if the standard path is blocked or does not display the necessary information.
Standard path through the settings menu
The most obvious and safe way to find out the SIM number on Xiaomi Redmi 10 is to use the built-in settings interface. The logic of the MIUI shell involves grouping all communication parameters in one section, which makes navigation intuitive. However, the path to the information you need can vary slightly depending on whether you are using the global version of the firmware or the Chinese version.
First, you need to unlock your smartphone screen and find the standard Settings app, which usually looks like a gear, and then you have to scroll down to the section that handles wireless networks, and depending on the software version, it can be called About Phone», «SIM-Maps and mobile networks, or just Profile, is where the basic information about your mobile connections is hidden.
When you go to the SIM management section, you will see a list of all the modules installed. If your Redmi 10 has two SIM cards installed, the system will display them as "SIM 1" and "SIM 2." By clicking on a specific card, you will be taken to the detailed information menu, where your current number should be displayed in the Phone Number field. If the field is empty, this means that the operator did not transfer data to the device, and the number will have to be manually registered.
⚠️ Note: If you see an unknown number or a blank field, don't rush to restart the phone. Often it's just a feature of the carrier that doesn't transmit the ID. MSISDN when registering.
It’s worth noting that in some versions of the MIUI shell, the path can be slightly changed by developers to optimize the menu, for example, in new updates for Redmi 10, information can be hidden inside the About section, at the top of the list, next to the phone model and the Android version, so that the user immediately sees key information about his gadget.
💡
If the number doesn't automatically show up, try removing the SIM card, erasing the contacts and pasting them back in, and sometimes the oxidation of the contacts interferes with reading the full profile data.
Use of the Phone application and contacts
An alternative and often faster way is to check information through a standard call app. In Xiaomi smartphones, the app often combines dialing, call history and contact management functions, and has direct access to SIM card data, as it is the system component responsible for voice communication.
Open the Phone app (green handset) and go to the Contacts tab. At the top of the screen, often under the account avatar or in the contact settings menu, information about the current SIM card may be displayed. In some cases, if you click on three dots in the upper right corner and select Settings and then "Additional," the system may show a number tied to the profile.
Another MIUI-specific method is the Business Card function, which is to make contacts, find your business card (usually the first one on the list or marked with a user icon), and the details of the business card can include the number that the system considers to be the primary number for the device, which is especially useful if you have previously synced data with your Mi Account or Google account.
- 📞 Open the Phone app and check the top status bar.
- 👤 Go to Contact» → «Settings» → search.
- 🆔 Check your “Business card” in the contact list for the displayed number.
- ⚙️ Use search by settings by typing in “phone number».
It’s important to understand that the Phone app takes data from the same source as the settings menu, but sometimes the information is caching differently. If the number is not visible in the settings, it’s unlikely that it will magically appear in contacts, but it’s worth checking out, especially on devices with custom themes that can hide standard interface elements.
Problem of missing number and manual entry
A fairly common situation for Xiaomi Redmi 10 owners is that there is no number in the appropriate settings field. This is not a phone breakdown or an operating system error. The fact is that technically, the phone number (MSISDN) is not stored on the SIM card chip necessarily for display to the user. The SIM card primarily contains IMSI (Subscriber Identifier) and encryption keys, and the number is just an entry in the operator's database that is associated with the IMSI.
When you insert a new SIM card, the phone reads IMSI and sends the request to the operator's network. The operator authorizes the device, but does not always send back the text string with the phone number to display in the menu. Which is why in many cases the field remains empty. The solution to this problem is manually entering the number, which does not affect the communication, but makes using the smartphone more convenient.
To write the number manually, go along the Settings path. → SIM-maps and mobile networks. Select the SIM card you want (e.g, SIM 1) Find the Phone Number field and click on it, open a keyboard that allows you to enter any number, enter your number in an international format or format familiar to your region.
Manual entry path:
Settings → SIM- Maps and Mobile Networks → [Select SIM] → Phone Number → EnterOnce saved, the number will be displayed in settings, in the SIM management widget in the notification curtain, and can be used by some forms autocomplete applications.This is a purely local setting of the Redmi 10 interface, it does not pass to subscribers when you call them, and does not affect charging.
⚠️ Warning: Manually entering a number does not activate the SIM card or change the operator's data. It's just a shortcut for your convenience. If you enter the wrong number, it will not affect the communication work, but it may confuse you when choosing a SIM card to call.
Check through USSD-codes and service commands
If the software methods do not give results or seem too long, you can always take advantage of the time tested. USSD-These are special commands that are sent directly to the operator's server, bypassing the smartphone menu. Xiaomi Redmi 10 supports all standard codes accepted in the phone. GSM-network.
Each mobile operator has its own unique code to check the number. For example, MTS has *100#, Beeline has *102#, MegaFon has *558#, and Tele2 has *155#. Yota devices often use *103#. You just need to open the Phone application, dial the appropriate combination and press the call button.
Once you send a request, you'll see a pop-up window with information from the operator, which usually shows your number, your current balance, and possibly the rest of the traffic, which is the most reliable method, since the information comes directly from the operator's database, eliminating any read errors by the phone.
| Operator. | USSD-code | The result |
|---|---|---|
| MTS | *100# | Balance and number |
| Beeline | *102# | Phone number |
| MegaFon | *558# | Info on the room |
| Tele2 | *155# | Balance and number |
| Yota | *103# | Tariff data |
There are also generic Android engineering codes, such as ##4636##. Once you enter the Testing menu, you can select Phone Information. MIUI With security protection, this access is often closed or does not display a phone number, showing only technical information. IMSI. Therefore USSD-Operator codes remain the preferred choice.
What is IMSI and why is it not a number?
Working with two SIM cards on Redmi 10
Xiaomi Redmi 10 is equipped with a hybrid slot that allows you to use two physical SIM-cards Nano-SIM format.
