How to transfer all the numbers to SIM-Xiaomi

Changing a mobile device or recovering data after a system reset is often stressful for smartphone owners.Saving important phone numbers has always been a priority, and in the Xiaomi ecosystem, this process has its own peculiarities that need to be considered.

Modern smartphones offer several ways to store information: internal memory of the device, cloud services and a physical chip. SIM-Despite the ubiquity of cloud technology, many users still prefer to store their contact database on a SIM card for rapid migration between devices without being tied to the Internet.

In this guide, we will discuss in detail the algorithms for moving numbers, discuss the limitations of the storage format, and answer frequent questions that arise when working with the MIUI.

Preparation for data portability and format verification

Before you start taking action, you need to make sure that the source data is available and correct. Often users try to copy numbers that are already on the SIM card, or search for them in the wrong storage. Open the standard Contacts app and go to the display settings.

Make sure you see all the records. Xiaomi’s interface may include a filter that hides certain groups or accounts. If you plan to transfer data from another device, import it into your phone’s memory first via Bluetooth or a.vcf file.

⚠️ Attention: SIM-The card has a strict limit on the length of the contact name (usually up to the 14-20 Long names will be cropped off when written, which may lead to confusion in the future.

It's also worth checking the space on the SIM card itself. Older chips can hold as little as 250 records, whereas modern USIM standards allow you to store more, but there's still a limit. If your phone book exceeds that volume, a full transfer is impossible without losing some data.

Exporting contacts from internal memory to SIM-map

The main method of transfer involves the use of built-in functionality of the MIUI shell. This method does not require the installation of third-party software and works even without access to the network. The process begins with opening the Contacts application on the home screen or in the Tools folder.

Then go to the control menu. Click on the three dots or menu icon in the corner of the screen and select Import/Export contacts. SIM-The system will automatically analyze the number of available records and free cells on the chip.

Once you have selected the contacts to copy (you can mark all or select specific ones), the system will request confirmation of the operation. Press OK and wait for the process to be completed. The speed of writing depends on the number of numbers, but usually takes no more than a minute for a standard phone book.

It's important to understand the difference between formats. When exporting, additional fields like email, address, photo of contact and additional numbers are lost, and only the primary name and one phone number are saved.

Import numbers from SIM-card in the memory of the smartphone

The reverse is when you insert a new SIM card with a ready-made number base into your Xiaomi and want to save that data to your phone’s memory or the cloud, which is a safer storage method, since it is not subject to physical wear and tear on the chip and allows you to store complete contact profiles.

The algorithm is similar to export, but requires the selection of another command. From the Import / Export contacts menu, select Import with SIM-The system will suggest selecting the target storage: Google account, Mi Account or device memory.

It is recommended to choose sync with your Google account, which will provide automatic backup. If you select Device Memory, the data will be tied only to that particular device, and if you lose or break your smartphone, it will be more difficult to restore it.

Using Mi Mover to Use Mass Migration

For users who have just purchased a new Xiaomi smartphone, there is a more powerful tool – Mi Mover. This system application allows you to transfer not only contacts, but also messages, photos, apps and settings from the old device to the new one.

Run the Mi Mover app on both devices, and on the new phone, select "I'm the recipient" and on the old phone, "I'm the sender." QR-code and connection establishment select Contact category in the list of transmitted data.

The main advantage of this method is that it does not copy the contacts to the SIM-A card is intermediate, and immediately places them in the selected storage of the new device, which allows you to bypass the length limitations of the name and save profile photos, if they are in the original database.

Wi-Fi Direct data transfer is much faster than writing to a SIM card chip, and for large phone books (over 1,000 numbers), this is the only reasonable way to avoid long waits and potential write errors.

💡

Use Mi Mover even if you have Android of a different brand.The app works with most Android 4.0 and higher devices, making it easy to upgrade to Xiaomi with Samsung, Huawei or LG.

Sync with your Google account and Mi Cloud

The most modern and reliable way to manage a contact book is cloud synchronization. SIM-The cloud has no physical limitations and protects data from loss when plastic or magnetic fields are damaged.

To set up Google sync, go to Settings → Accounts and Sync → Google. Make sure the switch opposite Contact is activated. Similar actions can be performed in the Mi Cloud app for Xiaomi ecosystem users.

When synchronization is enabled, any change in the phone book (add, delete, edit) is instantly reflected on all devices where the account is logged in, eliminating the need to flip numbers every time you change the phone.

⚠️ Warning: Before performing a full Hard Reset, be sure to check the sync status. If contacts do not have time to load into the cloud, they will be irretrievably lost after cleaning the memory.

Recovery from the cloud occurs automatically when you first start your smartphone after a reset or when you enter an account on a new device. You will not need to search for backup files or insert an old SIM card.

Frequent problems and methods of their solution

Users may encounter technical difficulties in the process of transferring data. One of the most common problems is the error "Memory" SIM-This means that the physical limit of the chip has been exhausted, in which case you need to delete some of the old or duplicate entries directly from the SIM card through the contact menu.

Another problem is name encoding: When you transfer from other devices (such as iPhones or old button phones), the names can be displayed by cranks, the solution is to export contacts to a.vcf file through a third-party application, and then import this file into the standard Xiaomi ledger.

If you've lost your contact photos after the transfer, don't panic. SIM-The cards do not support graphics, and photos must be restored separately if they were saved in an account profile or gallery.

💡

A SIM card is an aging media designed primarily for network identification, rather than storing multimedia data or large amounts of text.

Comparison of storage methods and final recommendations

So to sum up, it depends on your goals, if you want to quickly transfer numbers to a button phone or a device without internet, SIM-The map remains the only option, but for constant use of a Xiaomi smartphone, this is not the most efficient way to go.

Cloud services provide flexibility and security: you can clean your phone’s memory or change your SIM operator at any time without losing a single number. Local storage is suitable for those who strongly distrust the Internet, but require regular manual reservations.

Remember, regular backups are a rule of digital hygiene, and don't rely on just one method of storage, and the combination of cloud synchronization and periodic export of important numbers to a third-party medium will ensure that your contact information is as safe as possible.
