In this case, the screen displays the words "Unknown number" or just an empty field.

Search for numbers in the system settings MIUI and HyperOS
The simplest and most obvious way, often overlooked, is to go deep in the system menu. The MIUI shell traditionally provides detailed information about the SIM cards connected. You need to open the Settings app and scroll down the list or find the section related to SIM card management. Depending on the system version, this item may be called differently, but the logic remains the same.
Click on the About Phone section and then select the Status subsection or go straight to the menu. SIM-And this shows you the data for each card you've installed, and if the operator has transmitted the data correctly, you'll see your number next to "Phone Number." In the new versions of HyperOS, the path may look like Settings. → The phone. → General information → SIM-map.
Sometimes this menu doesn't show the number itself, but it shows a pseudonym you might have given earlier, like "Personal" or "Worker."

If it's empty, then the information wasn't automatically counted, and you'll have to use the other methods described below, which is good because it doesn't require the Internet or balance in your account.
⚠️ Note: If the settings show "Unknown number", it does not mean that the phone malfunctions. Most often the problem lies on the side of the carrier who did not write the data in the profile. SIM-map-out.
Use of the USSD-commands and service codes
A universal tool for interaction with the operator's network is USSD-They work even when there is no money on the balance sheet or no mobile Internet, and each major operator has its own unique code that instantly displays the number information on the smartphone screen. This is one of the most reliable ways, independent of the Android version or shell. MIUI.
To use this method, open the Phone app and enter the appropriate number combination. Once you have dialed the last digit or # symbol, the request is usually sent automatically. If this does not happen, click the call button. A pop-up with your number and possibly additional tariff information will appear on the screen.
Here is a table of basic codes for popular Russian operators. Keep this list so you don't search the web every time. Please note that codes can change by operators, so it's best to check the relevance on official websites.
| Operator. | USSD-team | Note |
|---|---|---|
| MTS | *100# or *100*10# | The information will come in SMS or on the screen |
| MegaFon | *500# | Instant screen output |
| Beeline | *110*10# | Requires confirmation of call |
| Tele2 | *155# or *61# | It works in most regions |
| Yota | *107# | Similar to the MegaFon network |
In some cases, after you enter the code, you may need to press the call button. If the request is not processed, check if the combination is correctly typed. SIM-The card is active and has a network signal, and this is ideal when you need to quickly find out the number on someone else's phone or a new device.
Determination of the number by sending messages

The text can be anything, such as "Verification." After sending, look at the interviewer's screen or your second phone, the sender's number will be listed in the message that came.
There is a more ingenious way that doesn't require a second phone, and some operators allow you to send a special service message with text, such as "My number" to a short service number, and an SMS will come back with your data, and the exact text and number for such a request should be clarified on your carrier's website, as they often change.
⚠️ Note: When sending messages to other carriers' numbers or to short service numbers, you may be charged according to your plan.
This is especially useful if you're in a low-reception area where voice calls are impossible, but SMS is not possible, and it's also useful when the person's phone is in Do Not Disturb mode and you just want to see your number in their call log or message log.

On Telegram, the path is similar: Settings - at the top, the name will be written number.
This method has one important advantage: it shows the number in an international format, which is useful if you need to tell it to a foreign contact, and it allows you to check which number is associated with your main messenger, which is important for security and two-factor authentication.

If you're not around, you can call your second phone, if you have one. In today's world, many people have two devices or the ability to take a call to a tablet/laptop using the same messenger, and the number will appear in the incoming call log.
Another option is to call the answering machine number or the numbering service, if it is connected. Some operators provide the service "Antispam" or "Number Defineer", which when calling a special service number, call your own number with a voice.
