Owners of smartphones Xiaomi, Redmi and Poco often face a situation when you need to urgently find out your phone number recorded on the phone. SIM-This can happen when you change your device, when you buy a new SIM card without packaging, or when you're just forgetful. MIUI The new HyperOS has its own features that sometimes hide this information from the user, making the standard path unobvious.
There are several proven methods to quickly access subscriber data. You can use system settings, USSD-operator requests or third-party utilities. In this article, we will discuss each method in detail, paying special attention to cases where the number does not automatically display due to the features of the firmware or SIM card format.
Before you get to the complicated manipulations, you should try the simplest and most logical option - checking through the Android settings menu. The system tries to read data directly from the SIM card chip, but the success of this operation depends on the quality of the recording of information by the operator.
Search for numbers in the system settings of Android
The first and most obvious way is to look at your device's Settings. The algorithm may vary slightly depending on the version of the Android operating system and the version of the MIUI shell, but the overall menu structure remains similar. You need to find the section responsible for managing SIM cards and mobile networks.
On most current models, navigation is like this: open the Settings app, then go to About Phone. Here, on the home page, SIM card data is often displayed. If the number is not visible immediately, click on the SIM card icon (SIM 1 SIM 2) or select Settings SIM-In the menu that opens, look for the field "Phone number».
Sometimes the system can't read the number automatically, and that happens if the operator doesn't write it into a special SIM card memory section when it's released, so instead of numbers, you'll see a dash, a zero, or a message, "Not known." Don't panic, it doesn't mean the phone is malfunctioning.
⚠️ Note: If the number field displays unreadable characters or a dash, this does not indicate a breakage of the smartphone. SIM-Map, not in Xiaomi software.
It is important for dual-symbol owners to check the data for each card separately. The system can successfully count the number from one SIM card and not see it on the other. It is also worth considering that on some global firmware, the path may differ: Settings → SIM cards and mobile networks → the choice of a specific card.
💡
If the number doesn't show up in the settings, try removing the SIM card, erasing the contacts with a pin and pasting them back in, and sometimes the contact oxidation interferes with reading.
Use of the USSD-call-and-call
When the system menu is silent, universal commands working at the operator network level come to the rescue. USSD-The search results are directly from the cell company, and this method works even on button phones, and it doesn't depend on your Xiaomi model.
Each major operator has a short code to verify the number, usually a combination of asterisks and numbers, typed in the Phone app, and below is a list of popular commands for Russian operators that are often used with Redmi and Poco devices:
- 📞 MTS: Dial *111*0887# or *111# and follow the menu instructions.
- 📞 Beeline: Team *110*10# It will instantly display the number on the screen.
- 📞 MegaFon: Use the request *105# or *105*00#.
- 📞 Tele2: type *155# or *155*00#.
- 📞 Yota: command *101# or *100#.
After dialing the command, press the call button. A pop-up will appear on the screen (USSD-Some operators also send information. SMS-a greeting and number message when you first activate your SIM card in your new device. Check the inbox in the Messages app.
Another easy way to do this is to call or send SMS You can go to a friend's phone, a relative's phone, or your second number, and the person's screen will display your current number. If you only have one phone on hand, you can use the numbering service if it is activated by the operator, or simply save your contact to the phone book under the name “I”, and then see the details of the contact.
The format problem SIM-map (2G/3G)
One of the most common reasons Xiaomi doesn’t show a number in the settings is the outdated SIM card format. If you use a SIM card that was released many years ago (the 2G standard or early 3G), it may not support writing the “MSISDN” field (your number) in the format that modern smartphones read.
Older SIM cards often have less memory and a simplified file system. When installed in a modern Redmi Note or Xiaomi Mi, the phone reads the basic data to register on the network (IMSI, encryption keys), but the field with the phone number remains empty, since in the old standards it was not required to transfer to the device.
The only solution is to replace the SIM card with a new one, which can be done in the carrier's cabin, keeping your current number and tariff. The procedure takes 10-15 minutes and is usually free or costs a symbolic amount. The new SIM card will be 4G/LTE standard (USIM), which is guaranteed to correctly transfer all data, including the number, to the Android system.
⚠️ Note: When you replace the SIM card from the operator, all contacts stored directly in the memory of the old SIM card will be lost. Before going to the salon, be sure to export the contacts to your Google account or save them to the internal memory of the phone.
Once you replace, you will notice that the phone number is automatically determined in the About settings, and the new SIM cards also provide more stable signal and support for modern communication standards, which will positively affect Internet speed and the quality of voice calls via VoLTE.
☑️ Checklist before replacement SIM-map
Management applications SIM-card
Many major carriers develop their own tariff management apps that are available on the Google Play Store.These apps often have access to SIM card information and can display your number in a user profile immediately after logging in.
To use this method, you need to connect your smartphone to a Wi-Fi network or mobile Internet. Download your operator’s official application (for example, “My MTS”, “My Beeline”, “MegaFon”, etc.). When you first start, the application usually automatically authorizes you by the SIM card number (via SMS or background request).
Once you log in, the phone number is often displayed in the top corner of the screen or in the Profile section, a convenient way to not only find out the number, but also monitor costs, connect services and change rates without calling in support.
| Operator. | Title of the annex | Substantive function | Demands the Internet. |
|---|---|---|---|
| MTS | My MTS. | Tariff management | Yes. |
| Beeline | My Beeline. | Balance and services | Yes. |
| MegaFon | MegaFon | Personal office | Yes. |
| Tele2 | My Tele2. | Tariffs and bonuses | Yes. |
Using carrier apps is especially important for users who change rates or add additional options, but it is worth remembering that these applications can consume battery power and background traffic, so once you receive information about the number, they can be temporarily disabled or removed.
Specifics of working with Dual SIM and VoLTE
Xiaomi smartphones are famous for their support for two SIM cards, but sometimes this creates confusion when determining the number. In the settings, it is important not to confuse the slots: SIM 1 and SIM 2. If you have two cards inserted, check the number for each of them separately, switching between tabs in the settings menu.
VoLTE (Voice over LTE) technology deserves special attention, allowing voice calls over 4G networks. On some models Poco and Xiaomi, when VoLTE is activated, there may be conflicts with the definition of a number if the firmware is not fully adapted for a particular operator, in which case the number may “disappear” from the settings, although the communication works.
If you are faced with this situation, try temporarily disabling 4G/LTE mode by switching the network to 3G Only or 2G/3G in the SIM card settings. After rebooting your phone, check if the number appears. If so, the problem is precisely VoLTE compatibility. Permanent solution may require updating the firmware or changing the region in the phone settings (for example, India or Global).
What is the phone region and how does it affect it?
It's also worth noting that when you use Flight Mode, you can temporarily not read your number. Make sure your flight mode is off and your SIM card is active. Sometimes it helps to just restart the communication module: turn on the flight mode for 10 seconds, then turn it off and wait for the network icons to appear.
Resetting network settings as a last resort
If none of the above methods worked and the number still doesn't show up, even though the SIM card is new and working, you can try resetting your network settings.This operation will return mobile internet, Bluetooth and Wi-Fi settings to factory values, but won't delete your personal files, contacts or apps.
To perform the reset, go along the path: Settings → Connection and Sharing (or “More”) → Reset Wi-Fi, mobile networks and Bluetooth. Press Reset button and confirm the action with a screen unlock password. After the reset, the phone will re-register in the operator’s network.
When you re-register, the system will re-request the SIM card, which in most cases helps to revive the phone number field in the settings, but if the number does not appear after that, the probability that it is not recorded on the SIM card by the operator is 99%.
⚠️ Note: After resetting your network settings, you will need to re-enter your Wi-Fi passwords and re-address Bluetooth devices such as headphones or watches.
In rare cases, cleaning the cache of the Phone or Contacts application can solve the problem, but this is less effective than completely resetting the network settings. If the problem persists on the new SIM card after all the manipulations, it makes sense to contact the operator's technical support with a question about the correctness of the subscriber profile record.
💡
Network resetting is a secure procedure that often solves number-detection problems, but requires reconfiguration of Wi-Fi and Bluetooth.
