Modern smartphones of Xiaomi, working on shells MIUI or new HyperOS, which have a complex data management system that often baffles new users. SIM-You want to see your phone numbers, but unlike older push-button phones, modern Android phones don't always automatically display the contents of the chip in the main phone book.
The problem is that by default, Xiaomiโs security and privacy system hides SIM contacts from direct access to avoid duplicate records. You need to manually activate the display or perform the import procedure. This is not a device error, but rather a feature of the Android architecture, where the main storage is considered to be a cloud account or internal memory of the phone.
In this article, we'll go into detail about all the ways you can access the numbers that are written on the chip, and we'll look at the system's standard tools, the hidden engineering menus, and third-party utilities. SIM-The card has limited memory and often crops long names or numbers with extra codes, so full porting to the phone's memory is a priority.
Why SIM contacts are not visible on the standard list
The main reason you donโt see numbers immediately after you install the card is because of the priorities of the Contacts app display.In the default settings, Xiaomi often chooses only the Mi Account or Google account to display the source.The carrierโs chip is ignored until the user explicitly tells the system to show it.
There is also a technical limitation to the format of storage on the card itself: Old GSM standards allowed only a base number and a short name to be stored, often without supporting Cyrillic or special characters. Modern Xiaomi smartphones can misinterpret name encoding if the correct display filter is not configured.
Also, the company has stepped up its privacy protection measures with newer versions of MIUI 14 and HyperOS, and accessing SIM reading now requires explicit permission or user action, which is part of Androidโs security policy, and it doesnโt want malware to stealthily copy your phone book.
โ ๏ธ Note: If you just inserted a card and see a request to enter PUK-code PIN, Do not enter random combinations. PIN-The code will block the card, and ten attempts with the PUK This will result in a complete lock without the possibility of recovery.
Configure the display of contacts in the phone application
The easiest and safest way to see the numbers you want is to change the filter in the standard application. You do not need to install additional software, since all the functionality is already built into the MIUI shell. First, open the standard Contacts app (usually an orange icon with a human silhouette).
In the interface that opens, look at the three dots in the top right corner or the menu button (three horizontal bars) and click on them, you will be taken to the display settings. Find the option "Display settings" or "Contacts for display." Here you will be asked to choose the source: All contacts, only Phone or SIM only.
Select an option that includes your SIM card, which is usually signed as SIM 1 or the carrier name (e.g. MTS, Beeline), and once you activate this slider, the list will instantly update, and you will see all the entries that are physically on the chip, and now you can not only see them, but also edit or copy them.
It's important to understand the difference between "display" and "import." As long as you just turn on the display, the numbers stay on the chip. If you delete them from the SIM card through the phone's menu, they disappear forever.
Step-by-step import of numbers in the memory of the phone
In order to secure your data and access all the functions of the smartphone (search by name, photo caller ID, integration with messengers), contacts must be transferred to internal memory or the cloud. The import process on Xiaomi is unified and executed through the management menu.
Go to the Contacts app, click three dots in the corner, and select Import/Export Contacts. The system will tell you to select a source. From the source list, find and click on your source. SIM-And then the system will scan the chip.
In the next step, you need to choose a destination, and it is recommended to choose โPhoneโ or, better yet, your Google account, and Google account selection will provide automatic synchronization: if you lose your phone, the numbers will be saved to the cloud.
โ๏ธ Import checklist
Once you've selected your destination, the system will ask you to confirm that you've copied all the records you've found, click OK or Import, and it'll take you seconds to a minute, depending on the number of records, and you'll see a successful copy notification when you're done.
Using the Engineering Menu for Diagnostics
In some cases, standard menus may not work properly due to software failures. To deeply diagnose the state of the SIM and check its readability, you can use the Xiaomi engineering menu, which is a hidden part of the system designed for testing equipment.
To get there, open the Phone app and enter a special combination: ##6484##. Immediately after entering the last star, the CIT menu (Customer Interaction Test) will open.
In the test list, find a SIM or Telephony item, and when you run the test, the system will try to read the card data and check its response, and if the test is successful, then the card is physically correct, and the problem lies in the software or display settings.
โ ๏ธ Warning: Do not change the settings in the engineering menu unless you are sure of their purpose. Accidental activation of certain modes (for example, disabling the radio module) can lead to loss of communication, which is difficult to restore without resetting the settings.
Third-party applications for contact management
If MIUI is not suitable or seems inconvenient for some reason, you can use the proven third-party solutions from the Google Play store. These applications often have more flexible filtering settings and allow you to work with multiple maps at the same time.
One popular solution is Contacts Optimizer, or similar utilities from trusted developers, which allows not only importing but also combining duplicates, clearing empty records and formatting numbers into an international standard.
When installing such an application, be sure to give it the necessary permissions to access contacts and telephone. Without these rights, the program will not be able to read data from the Internet. SIM-Once you've scanned, you can export the data in a format. VCF backup.

| Google Account | 25,000+ units. | Automatic. | High (2FA, cloud) |
| Mi Account. | No restrictions. | Automatic. | High (Xiaomi ecosystem) |

Frequent problems and their solution
Xiaomi users often experience a situation where names are displayed after importing but numbers are not dialed, or vice versa. This may be due to the format of recording the number. For example, if the number is written in an international format and you type in a local one, the phone may not find matches in the database.
Another common problem is broken records, where when you transfer from very old maps, some characters can be miscoded, turning into question marks or empty characters, in which case manual editing through the Change Contact menu helps.
If the phone doesn't see SIM-The card is in the import menu, try rebooting the device. In rare cases, it helps to remove the tray, wipe the contacts of the card with soft cloth and re-installe.
