Changing a smartphone is always stressful, not so much with getting used to a new interface as with the risk of losing important data. Xiaomi Redmi Note 9 owners often face the need to quickly and error-free to throw the phonebook from an old device. Fortunately, the Android ecosystem offers many flexible tools for data migration that work steadily and do not require deep technical knowledge.
In this article, we will take a look at all available sync methods, from cloud services to local file transfers. You will learn how to use a regular Mi Mover, how to set up a Google account correctly, and what to do if your old phone does not support modern transfer protocols. A competent approach will allow you to start using a new gadget immediately, without much settings and manually entering numbers.
Whether you’re moving from a budget device or a flagship brand, the algorithms will be similar, and the key is to choose the method that best suits your current situation and the state of both devices. Below are proven methods that ensure that your address book is safe.
Preparing devices for data migration
Before you start copying directly, you need to make sure that both smartphones are ready to go. First of all, check the battery level on both devices. If the charge is less than 30%, it is better to connect them to the power source so that the process does not interrupt halfway due to the discharge.
It is also critical to ensure a stable internet connection if you plan to use cloud services. For local transmission via Wi-Fi Direct or Bluetooth, make sure that the appropriate modules are activated in the notification curtain. The old phone should not be in power saving mode, as this may limit the background activity of applications.
⚠️ Note: Before starting any transactions with contacts, it is strongly recommended to make a backup copy of them to the SIM-card or file.vcf. This will protect you from accidental data loss in the event of a software failure during transmission.
Clear some free space on the new Redmi Note 9. Although contacts take up little memory, system sync processes may require a temporary buffer.Delete unnecessary screenshots or heavy files if the device's memory is almost full.
☑️ Ready for transfer
Method 1: Sync through a Google account
The most reliable and versatile method for Android users is to use Google cloud storage. If your old phone has been synced, then all contacts are already in the cloud. You just need to enter the same Gmail account when you first set up Xiaomi or add it later to the settings menu.
Automatic recovery is done in the background, and after you enter your password, the system will ask you what data to recover, make sure the switch opposite the Contacts item is activated, and depending on the number of entries in the phone book, it can take anywhere from a few seconds to a couple of minutes.
If automatic sync is not running, you can manually speed the process. To do this, go to the settings, find the account section and select the Google profile you want. In the menu that opens, click Sync and make sure the tick is next to the phone book.
What to do if contacts do not appear?
The advantage of this method is that your data will always be accessible from any device, whether it is a computer or a new smartphone, you can manage it through the Google Contacts web interface, delete duplicates and edit information in a convenient format.
Method 2: Use the Mi Mover application
Xiaomi has developed its own Mi Mover app, which is ideal for migrating from any Android or iOS device, allowing you to transfer not only contacts, but also photos, apps and system settings. The new Redmi Note 9 already has the default app installed.
To get started, open Mi Mover on both phones. On the old device, you may need to download the app from the Play Market or scan it. QR-code that will appear on the screen of the new smartphone. After connecting to Wi-Fi Direct, select the category "Contacts" and click the transfer button.
The data transfer speeds over Mi Mover are much faster than Bluetooth, because it uses a direct link between devices, and you can see the progress in real time, and once you've done that, the system automatically integrates the new entries into the general phone book.
- 📱 Cross-platform: Works between Android and iOS without losing data quality.
- ⚡ High speed: Uses a local Wi-Fi channel without consuming mobile traffic.
- 🔄 Full migration: transfers not only numbers, but also call history and SMS.
💡
When using Mi Mover, keep the screens of both smartphones on and don’t switch to other apps to avoid breaking the connection.
Importantly, when you transfer your contacts via Mi Mover, you should save them in your phone’s memory and copy them to your Google account for security, using the built-in contact management features.
Method 3: Transfer via Bluetooth and VCF file
If the Internet connection is unstable or you prefer local methods, you can use the export of contacts to a.vcf file. This method is universal and works even on very old phone models where there is no access to cloud services.
On the old device, open the contact app, select the menu, and click "Import/Export." Select "Export to Drive" or "Export to File." The system will create a file with all the numbers, which you then need to transfer to the Redmi Note 9 via Bluetooth or messenger.
Once you have a file on your new smartphone, just open it, and the system automatically prompts you to import the contacts you find, and you can choose where to store them: in your phone's memory, in your phone's memory. SIM-map or Google account.
| Method | Speed. | We need the Internet. | Risk of loss |
|---|---|---|---|
| Google Sync | Tall. | Yes. | Minimum |
| Mi Mover | Very high. | No. | Minimum |
| Bluetooth (VCF) | Low. | No. | Medium. |
| SIM-map | Medium | No. | High-pitched |
VCF files are convenient because they can be stored on a computer or flash drive as an archive, but when transmitted over Bluetooth, large files can be transmitted for a long time, and the process itself requires confirmation on both devices.
Method 4: Import with SIM-map
The oldest, but still relevant method is the use of SIM-It's a good idea if all the contacts are stored on a SIM instead of in the memory of an old phone, which is common in people with push-button phones or old smartphones.
Put it in. SIM-Map in Xiaomi Redmi Note 9. After registering on the network, open the Contacts app. In the settings menu (usually three dots or gear), find the item "Import / Export" and select "Import from" SIM-map".
The system will suggest you choose your destination, and the best way to choose your Google account is to not depend on a physical SIM in the future, and if you choose Device Memory, your contacts will only be linked to that phone.
⚠️ Note: When importing with SIM-cards may be cut off long names or additional numbers (working, home), as the storage format on the SIM card has serious limitations on the amount of data.
After importing, do not rush to delete the numbers from the SIM card, make sure that they are correctly displayed in the phone book of the new device and you can make a call to them.
Solving and eliminating duplicates
Often, after the transfer, users are faced with the problem of duplication of records, this occurs when the same contact is stored in the memory of the phone, in the Google account, and on the Internet. SIM-Xiaomi has a built-in tool to solve this problem.
Open the contact app, go to the settings, and find the item "Combine duplicate contacts." The system automatically analyzes the database and suggests combining records with the same names or numbers, which will clear the list and make it neat.
If some contacts are not transmitted or are displayed incorrectly (for example, instead of a number name), check the file encoding when importing or try to restart the smartphone.
💡
Regularly cleaning up duplicates and saving contacts in the Google cloud is the best way to prevent data loss when changing devices.
In rare cases, manual import may be required. To do this, select a file from the import menu that previously saved backup. Make sure the file format is supported by the system (standard.vcf or.csv).
Safety outcomes and recommendations
Transferring contacts to the Xiaomi Redmi Note 9 is a simple procedure, if you know the right procedure, the most effective and modern way is synchronization through Google, which provides instant access to data from any device in the world.
However, having a local VCF copy or using Mi Mover provides additional insurance, and combining these methods to maximize reliability, and don’t neglect regular backups, even if you don’t plan to change your phone anytime soon.
Remember that digital hygiene is important for personal data security: periodically check which apps have access to your phone book, and remove unnecessary permissions in your privacy settings.
