In some cases, the number field can be empty because of operator reading or memory incorrect recording. SIM-Knowing where to look for this information will eliminate the need to call friends or look for a check with a contract.
There are several proven methods of obtaining this data: from standard system settings to engineering menus and USSD-Each method has its own nuances, depending on the firmware version and device model. In this article, we will discuss all options in detail so that you can quickly find the information you need, regardless of what kind of Xiaomi you have.

Use of the USSD-codes and calls
If you can't find information through the menu, you can use universal commands that work at the operator's network level, which is the most reliable method, since the data is requested directly by the mobile operator's database, rather than being read from a plastic card.

☑️ Checking the number display
Solving the problem of number determination

When you release new cards, carriers often don't write a number in the MSISDN (Mobile Station International Subscriber Directory Number) field on a chip, relying on network authorization. The smartphone reads the card, sees that the field is empty, and writes "Unknown." This can only be solved by manually entering the number into the phone's settings, which does not change the data to SIM, but allows the system and applications to "see" the number.

1. Go to Settings.
2. Go to About the Phone → Status (or immediately in settings) SIM-map).
