Switching to a new smartphone Xiaomi, Redmi or POCO This is often accompanied by the need to migrate user data, and the most critical element is the phone book. Many users, either for habit or compatibility reasons, prefer to store numbers directly on the phone. SIM-It's a card that you can access from any device without having to link to cloud services or the internal memory of a particular gadget. MIUI HyperOS has its own nuances that can put an inexperienced owner in the head.
Unlike some other manufacturers, Xiaomi uses its own implementation of the contact interface, which is not always intuitive when trying to mass transfer. You will have to navigating through several menus to find the hidden import function, since it is often hidden in the depth of the settings of the Contacts application. Understanding the logic of the Android address book will help avoid duplication of records and loss of important data during the movement.
In this article, we will take a closer look at all the available ways to transfer numbers, look at the common errors when the system refuses to copy data, and explain why storing contacts on a SIM in 2026 may not be the most reliable option. You will learn how to properly prepare a database before exporting and what restrictions you impose yourself. SIM-map of length and format of retained names.
Preparation of the telephone book for transfer
Before you start copying directly, you need to audit the existing records. Often users do not suspect that their contacts are scattered across different sources: some is stored in the memory of a Google account, some is stored locally in the memory of the phone, and some may already be on a SIM. To successfully perform the operation, all the target numbers must be in a single storage available for export.
Open the Contacts app and go to edit or group management mode. If you see numbers scattered, first synchronize or manually transfer all records to the device's internal memory. This is a critical step, as the export function is to be used to control the data. SIM-Xiaomi card usually only works with the phone’s local database, ignoring cloud records before they are downloaded.
💡
Before mass transfer, remove all duplicate contacts, otherwise on the SIM-The card may appear repeating records with the same numbers, but different names.
Pay attention to the format of names. SIM-The card has strict limits on the number of characters in the contact name (usually up to the end of the contact date). 14-16 Long names will be cropped and special characters or emojis may be incorrect or cause an error of entry. It is recommended to shorten long company names or full names to last names in advance.
The standard way to copy through the contact menu
The main method of transfer is built directly into the regular application of the phone book MIUI. This method does not require the installation of third-party software and works on all current models, from the budget Redmi Note to the flagship Xiaomi 14. The algorithm of actions may vary slightly depending on the version of the operating system, but the overall logic remains the same.
To start, open the Contacts app. In the upper right corner of the screen, find the menu button, which often looks like three dots or three horizontal bars. When you click on it, you will see a drop-down list of actions. You are interested in Import/Export contacts (or simply Export/Import).
In the menu, select the option Export to SIM-The system automatically tells you to choose a source if you have multiple accounts or storage facilities. Choose a phone or a Device. Then the process of checking and copying begins. If there are many contacts, the process can take several seconds.

It's worth noting that in some versions of the HyperOS shell, the interface can be slightly altered. If you don't see the direct "Export to SIM" item, look for the Settings button inside the contacts app, and then the Contact Management section, which is where advanced storage features often hide.
Alternative methods and third-party applications
If Xiaomi’s standard tools fail to perform the operation (for example, the menu is blocked or the function is buggy), you can use proven third-party utilities from Google Play. They often provide a more flexible interface for working with the address book and allow you to filter contacts before copying.
One of the most popular solutions is the Copy My Data application or specialized managers. SIM-They allow you to visually see which numbers are being moved and edit them on the fly, which is especially useful if you want to adapt names to the limitations of the SIM.
Why can third-party applications not work?
There is also a method of copying through an intermediate.vcf file. You can export all contacts to a file, save it, and then try to import that file by selecting as the recipient. SIM-However, this method does not work on all devices, since Android often defaults to save imported data to internal memory or Google account, ignoring the SIM.
Common problems and mistakes in export
Xiaomi users often face a situation where, after pressing the export button, the process is completed instantly, but contacts on the SIM do not appear. SIM-Old SIMs can only store 250 contacts, and if you try to flip 500 numbers, the system will either give you an error or only copy a fraction of it.
Another common problem is the format of the numbers, if the phone book has numbers in an international format (via the phone book). +7 or 8), and the SIM card has encoding limitations or conflicts, the entry may not pass, and it is also worth checking whether the entry on the SIM card is blocked through the security settings of the communication module itself (PIN-simplifier).
⚠️ Note: When copying contacts to SIM-However, if you subsequently delete contacts from your phone hoping they remain on the SIM, make sure that the export is successful, as the reverse process (from SIM to phone) sometimes takes place with the loss of some data.
Another mistake is trying to keep contacts with long names or photos. SIM-The map doesn't technically support storing images and long lines of text, and the photos will be lost and the names will be cropped, and it's not a system failure, it's a physical limitation of the technology of the old chips.
Comparison of storage: SIM, Phone or Google?
In the cloud age, physical mapping is archaic, but it has its advantages. To understand what works best for you, let’s compare the basic characteristics of different types of storage in the Android ecosystem.
| Parameter | SIM-map | Phone memory | Google Account |
|---|---|---|---|
| Memory capacity | Limited (250-500 contacts) | Depends on the model (thousands) | Almost unlimited. |
| Length of name | Up to 14-16 characters | No restrictions. | No restrictions. |
| Photo preservation | Not supported | Supported | Supported |
| Availability | On any phone with this SIM. | Only on this device. | On any device with the Internet |
As you can see from the table, Google Account is the most functional solution, allowing you to restore contacts even if you lose or steal your smartphone completely, which a SIM card can not do. SIM-The card remains indispensable for users who often change phones to buttons or work in areas without network coverage where synchronization is impossible.
Re-establishment of contacts with SIM-map
If you do decide to store numbers on a SIM or just bought a new Xiaomi and want to download old numbers, the import procedure is also simple: insert the SIM card into the device slot and make sure that it is determined by the network.
Go to the Contacts app, click on the settings menu and select Import/Export Contacts. This time you need the Import with option. SIM-The system will suggest you to choose a destination where to save the data. It is best to choose a Google Account or a Phone, but not the phone itself. SIM-map to avoid creating duplicates.
⚠️ Note: When importing with SIM-If you have two SIMs, the system will ask you which data to count from, and if you choose a slot, you will not start importing or copy the wrong contacts.
Once the process is complete, it is recommended to check several random numbers by calling them or opening a contact card. Make sure the numbers are correctly recognized and have the correct international format. If the numbers are written without a country code, which you need, they can be edited in batches through Google Contacts services on your computer.
