Buying a new smartphone, particularly the popular Xiaomi Redmi Note 10, is always accompanied by a desire to start using the device faster without being distracted by routine settings. The most critical task for most users is to migrate a personal database, because losing important numbers can lead to serious problems in communication or business. Fortunately, the MIUI ecosystem offers many built-in tools for quickly and securely copying information.
In this guide, we will take a look at how to transfer contacts from your phone to another Xiaomi Redmi Note 10 phone using a variety of methods, from cloud services to direct transmission by cable. You will learn how to work with vCard files, how to properly sync a Google account and what to do if old numbers are stored on a SIM card.
Before you start active, make sure that both devices are at least 50-60% charged; sudden power surges or discharges at the most inopportune moment can interrupt the process of writing data to the memory of a new gadget; and check whether you have a stable Internet connection if you plan to use cloud sync methods through Mi Cloud or Google servers.
Using the Mi Mover app for quick migration
The most efficient and modern way Xiaomi offers is to use the Mi Mover app, which is pre-installed on all new MIUI devices, and allows you to transfer not only contacts, but also photos, applications, system settings and even the location of icons on the desktop. For older Android devices, the application can be downloaded from the Google Play store, which makes the method universal.
The process starts quite simply: on the new Redmi Note 10, you need to open the application through the settings menu or find it in the Tools folder. Once the terms of use are accepted, the system will prompt you to choose the role of the device: “I am the sender” (old phone) or “I am the recipient” (new Xiaomi). It'll be on the screen next. QR-code that must be scanned by the camera of an old smartphone, having previously connected to the created Wi-Fi network.
⚠️ Warning: While running Mi Mover, do not switch to other applications or block the device screen, as this can break the connection and interrupt the transfer of large amounts of data.
Once the connection is established, the user is asked to select data categories for transfer. In this case, the main interest is Contacts, but you should also pay attention to Messages and Calls, so that the communication history is preserved completely. The speed of transfer depends on the volume of data and the version of Wi-Fi modules in the devices, but for text information this process takes seconds.
☑️ Preparation for transfer via Mi Mover
Synchronization through Google account
Android device owners often underestimate the power of cloud sync, which allows you to store contacts securely and access them from any device. If your old smartphone was enabled sync, then when you enter the same Google account on the new Redmi Note 10, all numbers will load automatically in the background, which is the most reliable way to prevent data loss in the physical breakdown of the phone.
To check the sync status on your old device, go to the settings, find the Accounts or Users and Accounts section, select your Google profile, and make sure the switch opposite the Contacts item is activated. If the sync has been disabled, you need to turn it on and press the Forced Update button until the process is over. On a new phone, it is enough to simply add the same account when you first set up the system.
The advantage of this method is the ability to edit contacts through the Google Contacts web interface from a computer, which is convenient for cleaning duplicates and sorting. However, it is worth remembering that the free version of the account has a storage limit that is shared between mail, photos and documents, although for text recordings of this place is more than enough. If you have problems with displaying numbers, you can try to clear the cache of the Contacts application through the application settings.
What to do if your contacts are not synchronized?
Transfer of contacts from SIM-card
Despite the development of digital technologies, many users still store phone books directly on the Internet. SIM-This creates certain limitations, since the SIM has a small amount of memory and often crops long names or does not support saving multiple numbers for a single contact. However, for Xiaomi Redmi Note 10, the process of importing from the SIM card is implemented as simple as possible and does not require third-party software.
To transfer the records, insert yours. SIM-card to the new smartphone slot (or use an adapter if the dimensions don’t match, although the Redmi Note 10 uses the standard nano-SIM). Once the network is up, open the standard Contacts app, click on the three dots in the upper right corner to enter the menu, and select Import Contacts «SIM-Map and target folder, it is best to choose your Google account for later sync.
| Parameter | SIM-map | Google Account | Phone memory |
|---|---|---|---|
| Capacity | Limited (usually 250) | Almost unlimited. | Depends on free memory. |
| Length of name | Limited by symbols | No restrictions. | No restrictions. |
| Supplementary fields | Only number and name. | Photo, email, address, notes | Photo, email, address, notes |
| Security | Low (when the SIMKA is lost) | High (cloud storage) | Average (lost when discharged) |
After importation is completed, it is strongly recommended that SIM-If some of the records are missing or are not displayed correctly, it may have been recorded with errors on the chip itself, in which case manual correction or re-importation may be required using an intermediate device.
💡
For importation with SIM-Select saving your cards to your Google account instead of your phone memory, which will protect your contacts from loss in the event of a reset or breakage of your Xiaomi smartphone.
Export and import via vCard (.vcf)
The universal language for sharing contact information is the vCard format (files with the extension.vcf). This method is ideal in situations where you need to transfer contacts to the Xiaomi Redmi Note 10 from a device that does not support direct transmission, or if you want to make a backup on your computer. The vCard file can contain one contact or thousands of records in one archive, while maintaining the data structure.
On an old phone, you need to go to the contact app, select the export option, and specify the location of the save. The resulting file can be transferred in any convenient way: via messengers (Telegram, WhatsApp), via email or via Bluetooth. On the new device, you just open the resulting file, and the MIUI system automatically prompts you to import the entries contained in it into the selected directory.
⚠️ Note: When transferring a vCard file via messengers, make sure you send it as a document, not as a media file, so as not to damage the encoding structure and lose some of the data.
This method is also useful for cleaning the phone book from duplicates. By downloading the vCard file to your computer, you can open it in special editor programs or even in a notebook (for experienced users) to delete unnecessary entries before downloading to the new Redmi Note 10.
Transmission via Bluetooth and Mi Share
If you don't have the Internet at hand, and the Mi Mover application for some reason does not run, you can use the classic Bluetooth protocol or its modern version from Xiaomi - Mi Share. These technologies allow you to transfer vCard files directly between devices without using intermediate servers. The transfer speed over Bluetooth is low, but for text files with contacts it is quite acceptable.
To implement this method, both devices need to enable visibility for other devices and pair. In the old phone's contact app, select the desired entries (or all at once), click the Share button and select Bluetooth. Redmi Note 10 will request acceptance of the file, after which the download will begin.
Mi Share technology is much faster, and uses a combination of Bluetooth for detection and Wi-Fi Direct for data transfer. It is built into the MIUI shell and allows you to transfer contacts simply by selecting them from the list and clicking the “Send” button in the notification curtain. This is especially useful if you are transferring data from another Xiaomi smartphone or device with the Mi service framework installed.
Addressing problems and duplicates
After the transfer process to Xiaomi Redmi Note 10, users often face the problem of duplication of records. SIM-It's a map, and it's a phone memory, and it's a cloud. MIUI has a built-in tool for combining such records, which can be found in the contact management menu.
To clear the list, open the Contacts app, go to the settings, and find the "Combine Repeated Contacts" item, and the system will analyze the database and suggest entries with the same names or phone numbers, which will significantly streamline the phone book and make it easier to find the right subscribers in the future.
Sometimes contacts don’t show up even though they’ve been successfully transferred, so check the display settings: select Contact Filter from the contacts menu and make sure that the “All Contacts” check box is in place or the accounts that have been imported are selected. It is also important to check if the contact with SIM-maps in display settings.
💡
Regular synchronization with Google account is the best prevention of contact loss and the appearance of duplicates when changing devices.
