Many Xiaomi smartphone users, when switching from button phones or other Android devices, face an unexpected limitation of the MIUI interface. The default system often hides the contents of the SIM card itself, displaying only numbers stored in the phone's memory or Google's cloud account. This creates the illusion of data loss, although in fact the contacts are simply not synchronized with the main storage of the smartphone.
This problem doesn't require root rights or complex reprogramming of the device, but rather to properly configure the source mapping in the standard Contacts app or use proven import methods, and understanding the logic of how the MIUI shell works will help you quickly restore access to the desired numbers.
In this article, we will discuss in detail how to force the display of data from the SIM card, how to transfer them to the cloud for security and what nuances should be considered by owners of dual-sim devices. SIM card has a limited amount of memory and does not support the storage of additional fields such as email or address, so transferring to the memory of the phone is a must-have for full use.
Why Xiaomi is hiding contacts from the SIM card
The main reason you don't see the numbers is because of the MIUI design philosophy, which is that Xiaomi's developers believe that plastic-based contact storage is an archaic method that carries the risk of data loss when a card is broken or lost, so the interface is tailored to work with cloud services.
The standard contact app, by default, filters out sources that are synchronized, and if you just inserted a SIM card from an old phone, the system sees new records, but it doesn't want to share them without your direct permission, and it's not a bug, it's a feature of the sorting algorithm.
In addition, the technical limitations of the storage format on the SIM card do not allow the display of avatars, additional numbers or social profiles, which also affects the priority of output.
⚠️ Note: Do not try to edit contacts directly on the SIM card through third-party menus. The format of storage on the chip is extremely primitive and can lead to the trimming of long names or the loss of some numbers when writing.
Understanding these limitations helps you to build a proper strategy for dealing with the phone book, so instead of fighting the system, it is better to correctly import all the data into a convenient digital format.
Display settings in the Contacts app
The first and easiest way to see hidden numbers is to change the filtering settings in a standard application, which doesn't carry data, it just makes it visible in a shared list. To start, open the Contacts app (a yellow icon with a human silhouette).
At the top of the screen or in the menu (three dots or three bars), find Settings or Contact Filter. In some versions of MIUI, this item is hidden in the Display submenu. You need to find the option responsible for contact sources.
By default, there's a checkmark just opposite to "Phone" or "Google." You have to manually activate the item. SIM-And then the list will be instantly updated, and you'll see all the numbers saved on the chip, often marked with a specific icon.
- 📱 Open the Contacts app on the main screen.
- ⚙️ Click on three dots in the corner and select Settings. → Contact filter.
- ✅ Put a tick in front of yours. SIM-map (SIM 1 SIM 2).
- 🔄 Click “Ready” or go back to update the list.
Once you do this, all the numbers will be available for viewing and calling, but remember that this is only a temporary visualization solution, and for reliable storage, you'll better move the data.
☑️ Checking the display settings
Importing contacts with phone memory
To make numbers a part of your digital life on Xiaomi, you need to transfer them from your SIM card to your internal memory or account, a process called importation, which ensures that you don't lose important information when you change your phone or lose your SIM.
Go to the contact settings as described in the previous section and find "Import contacts." The system will prompt you to select a source. SIM-Next, you will need to specify the destination: it is recommended to choose a Google or Mi Account for automatic synchronization.
Way to import: Contacts → Settings (three points) → Import / Export contacts → Import from SIM-cardIt takes a few seconds. Once completed, the system can suggest that you remove the originals from the SIM card, which is a safe operation if you're convinced that the import was successful, and now your contacts are protected from mechanical damage to the plastic.
| Parameter | SIM-map | Phone Memory / Google |
|---|---|---|
| Name limit | Up to 14 characters | No restrictions. |
| Supplementary fields | No (only number) | Email, address, website |
| Avatar | Not supported | Supported |
| Security | Low (physical carrier) | High (cloud) |
| Number of fields | 1 number in name | Lots of numbers in the name |
Using cloud storage offers another advantage: the ability to edit contacts from a computer, you can conveniently assign people to groups, add photos and clarify names, which is impossible to do through the SIM card menu.
💡
Tip: Make sure to back up after importing. Go to contacts.google.com and make sure all the numbers are there.This is your insurance policy against any technical failures.
Use of the application SIM-management
In the new versions of the shell MIUI Xiaomi has introduced a separate system application for managing SIM cards. SIM-maps and mobile networks or simply SIM-It's a more powerful tool than the standard contact menu.
Not only can you see the list, but you can also control the behavior of each SIM card separately, and this is especially true for dual-symbol devices, where contacts can be shared between two chips, and the app allows you to copy data in batches.
To find this tool, go to the general phone settings, then to the About Phone section (in some versions) or immediately to the phone. SIM-maps and mobile networks. The SIM card management menu often has a "Contacts to" button. SIM-map that opens a native interface to work with them.
- 📂 Go to Settings. → Annexes → All applications.
- 🔍 Find the system application in the list SIM-map.
- 📋 Select the Contact Management option SIM.
- 📥 Use the Copy button for mass transfer.
The interface is more ascetic, but functional, and allows you to work with contacts even if the main Contacts app is not correctly displaying sources for some reason.
⚠️ Note: When copying contacts through SIM-Management watch for duplicates carefully, and the system may not warn you of a repeat record if the names are written with different encodings or spaces.
Using this system tool is preferable, as it has higher access rights to the modem hardware than third-party programs from the app store.
What to do if the menu SIM-blank?
Working with two-symbol devices
Owners of Xiaomi smartphones with two SIM cards are often confused about the sources of contacts. The system can label numbers differently: the SIM 1 or SIM 2 icon next to the subscriber's name helps to understand where the record is physically stored.
When importing, it's important to choose the right SIM card as the source, and if you insert two old SIMs, you'll have to import twice, first for one, selecting it as the source, then for the second, and remember to switch the filter or source to the settings menu after the first import.
You also need to look at the call settings, and you can use the call settings menu to ask which SIM card to use if the caller's number is not connected to a particular network, and that will eliminate the constant system questions when dialing.
Duplicates are a common problem when working with two SIMs. If the same number is written on both cards, after importing into the phone, you will have two identical records. MIUI is able to combine them, but it is better to do it manually for the sake of cleanliness of the base.
💡
The main rule of two sims: Always check which SIM card you are importing from so that you don’t miss half the contacts stored on the second chip.
Solution and alternative methods
Sometimes standard methods don’t work: contacts aren’t imported, the list is empty, or there is a read error, which can be due to damage to the SIM card file system or incompatibility of the storage format.
In such cases, you can use third-party apps from Google Play, such as “Copy My Contacts” or “SIM Card Manager”, which often have more flexible settings and can “pull out” data that the standard interface of Xiaomi ignores.
Another reliable method is to use an old phone as an intermediary: insert a SIM card into a device based on pure Android or iOS, export contacts to a.vcf file, transfer the file to Xiaomi via Bluetooth or messenger and open it. The system automatically prompts you to import all records.
- 📲 The system will ask where to save: choose Google or Phone.
This method is considered the “gold standard” because the.vcf format is universal and retains the entire data structure, including avatars and additional fields, if they were on the source device.
