Changing your smartphone is always stressful, not so much with getting used to a new interface as with the risk of losing important data. Owners of the Xiaomi Redmi Note 10 model often wonder how to migrate a phone book from an old Android device as quickly and without loss. Fortunately, the Google ecosystem and proprietary MIUI tools offer several reliable ways to solve this problem.
In this article, we will take a look at all the available methods, from cloud sync through a Google account to using a specialized Mi Mover app. You will learn how to avoid duplication of records and why it is important to check the format of saving numbers before starting the procedure.
Before you start, make sure both devices are at least 50 percent charged, data transfers can take time, especially if you have photos or additional notes on your contact list, and a stable Internet connection will also be a key success factor for cloud services.
Preparing the old device and Redmi Note 10
The first step is always to carefully prepare the source material. On an old smartphone, you need to make sure that all the numbers are stored in the account memory or on the account. SIM-map, not in the phone's local storage, which may not be available after a reset. Open the Contacts app, go to settings and select Import/Export to check the current location of records.
The new Xiaomi Redmi Note 10 should perform an initial setup, and the first time you turn on, the setup wizard will prompt you to log into your Google account. This is a critical point: if you use the same account as on your old phone, some of the data can be pulled up automatically, but to ensure the result, it is better to perform a full transfer through special tools.
⚠️ Warning: Do not start the transfer process if both devices are power-saving mode.It can limit the background activity of applications, which will cause the connection to break in the middle of the procedure.
It’s also worth checking the amount of free memory. Although text contacts take up minimal space, synchronizing them with avatars may require additional space. Make sure that at least 500 MB of free memory is available on the Redmi Note 10 for the proper operation of system import processes.
Synchronization through Google Account
The most versatile and reliable way to run any version of Android is through Google’s cloud sync, which requires no additional software installation and works even if you’re switching from a device of another brand, such as Samsung or Huawei, and the main condition is that you have an active Internet connection on both devices.
On your old phone, open Settings, search for Accounts or Users and Accounts. Select your Google profile and make sure the switch next to Contacts is active. Click on the menu (three dots) and select Sync. Once the process is complete, the data will be uploaded to the corporation's servers.
On the Xiaomi Redmi Note 10, the same thing happens: log in to the same account, activate contact sync, automatically detect new entries and add them to the phone book, and if that doesn't happen, you can force the update through the account menu.
- 📱 Open the settings on the old device.
- ☁️ Check the sync status of Google Contacts.
- 🔄 Sign in to the same account on Redmi Note 10.
- ✅ Wait until the automatic list update is completed.
The advantage of this method is that your contacts will always be safe in the cloud. Even if you lose your phone, just enter your username and password on any device to restore the entire database. For owners of Redmi Note 10, it also means that contacts will be accessible through Google's web interest on your computer.
💡
If there are many contacts (more) 2000), synchronization may take up to 15-20 Do not close your account settings until you have a successful termination message.
Use of the Mi Mover app
Xiaomi’s Mi Mover utility is designed specifically to quickly migrate data to the brand’s devices, allowing users to transfer not only contacts, but also SMS, call history, apps and media files over Wi-Fi Direct without consuming mobile traffic. The app is pre-installed on Redmi Note 10 and available for download on other Android smartphones.
Run the app on both devices. Select Receiver status on the new phone and Sender on the old one. The new phone's camera will offer scanning. QR-code displayed on the screen of the old device, or you can choose to connect through the search for devices in the list of Wi-Fi networks.
Once you've established the connection, you'll see a data selection screen, and you'll check the box against Contacts, and you can deselect from the other categories if you only need phone numbers, and then you'll click Send and wait until the progress bar is complete.
☑️ Checklist for Mi Mover
The speed of transmission through Mi Mover is much faster than through Bluetooth or the cloud, because it creates a direct local connection, but it is important to keep the phones close to each other, and interruption of communication can lead to the fact that some contacts will not be recorded, and the procedure will have to be repeated.
⚠️ Note: When using Mi Mover on an older Android device (such as custom firmware), the application may request extended permissions. Grant all the rights requested, otherwise access to the database will be blocked by the system.
Transfer through SIM-map and Bluetooth
If the internet is not available or you prefer classical methods, you can use the Internet. SIM-This is suitable for basic contacts, but has limitations: usually only the name and number are saved, without additional fields such as email, address or multiple numbers per subscriber.
On your old phone, go to the Contacts app, select the settings and Import/Export. Select Export to Export. SIM-The system will warn you of possible loss of data. Confirm the action. Once completed, remove the card and paste into the Xiaomi Redmi Note 10 (using a paper clip for the tray).
On the new device, go back to Contacts» → «Import/Export and select “Import with” SIM-Indicate where to save data: it is recommended to choose a Google account or phone memory, but not the phone itself. SIM-map to avoid creating duplicates.
| Method | Speed. | Data stored | Requirements |
|---|---|---|---|
| Google Account | Medium | Everything (photo, email, notes) | Internet |
| Mi Mover | Tall. | All + apps and SMS | Mi Mover appendix |
| SIM-map | Low. | Name and number only | Physical access |
| File.vcf | Medium | All data. | File manager |
The alternative is Bluetooth transmission. On an older device, select all contacts, click Share, and select Bluetooth. On the Redmi Note 10, accept the file. The system will suggest importing data from the resulting.vcf file. This method is convenient if you want to transfer contacts to someone else, not yourself.
What to do if your contacts are not readable with SIM?
Work with VCF files and local import
VCF (vCard) is the industry standard for storing contact information, which allows you to save your entire profile in one file, and this is ideal if you want to back up before any manipulation or transfer data without linking to your accounts in real time.
On an old phone, export contacts to internal memory. The file is usually called contacts.vcf and is stored in the root of the memory or Downloads folder. Pass this file to the Xiaomi Redmi Note 10 in any convenient way: via messenger (Telegram, WhatsApp), email or USB-cable.
Once you have a file on a new device, just open it. Android automatically recognizes the format and runs the import wizard. You will be prompted to select an account to which entries will be added. Select your primary Google account to automatically sync in the future.
- 📂 Create a backup in.vcf format on your old device.
- 📤 Transfer the file to Redmi Note 10.
- 📥 Open the file and confirm the import.
- 💾 Select a target account to save.
The good thing about this is that it's independent of the Internet speed at the time of transfer, so you can prepare a file at home on fast Wi-Fi, and import it on the way, using only the phone's local storage. For the Redmi Note 10, it's a standard feature that doesn't require superuser rights.
💡
The.vcf file is a universal format that opens on any smartphone, tablet or computer, making it the best choice for long-term phone book archiving.
Solutions (often encountered problems)
Sometimes, the transfer process can be technically difficult, and one of the most common problems is duplicate contacts, which happens when you import data that has already been partially synchronized, or when the numbers are stored on both the SIM and the phone's memory simultaneously.
MIUI has a built-in tool to solve this problem: Go to the Contacts app, click on the menu or profile icon, and find the item "Merge duplicates", the system will analyze the database and suggest combining entries with the same numbers or names into one card.
Another problem is that there are no fields after importing, so if you were migrating data from a very old phone (like Android 4 or 5), some fields might not be supported by the new format, which can be done by manually inspecting important contacts and adding information.
⚠️ Warning: If contact photos are missing after transfer, don't panic. Often they are uploaded separately. Go to your Google account settings on Redmi Note 10, turn off and turn on contact sync again to initiate downloading media attachments.
Also, users sometimes encounter an error “Not enough space” even when there is free memory, which may be due to a crowded cache of the Contacts app. Go to Settings → Apps → All Apps → Contacts → Memory and click “Clear Cache” (do not confuse “Clear Data” if you do not want to delete the current database).
