Changing a mobile device often involves the need for fast and reliable transfer of user data, among which the first place in the importance is the phone book. For owners of Xiaomi smartphones, in particular the popular line of Redmi Note, the procedure of transferring contacts from another Android device can be done in several ways, but the use of Bluetooth remains one of the most versatile methods that do not require an Internet connection or the use of cloud services.
This method is especially relevant in situations where there is no stable Wi-Fi connection, or the user prefers local data transfer for security and privacy. Despite the fact that the speed of transmission over Bluetooth is lower than over Wi-Fi Direct, for text recordings, this parameter is not crucial, the main thing is to ensure the right sequence of actions to avoid losing numbering or duplication of records in the new system.
In this article, we will take a closer look at all the nuances of the process, from preparing files on an old device to importing them into the standard Contacts app on Xiaomi. We will look at possible pairing errors and how to fix them, which will allow you to successfully complete the data migration even when using devices of different generations.
Preparation of devices for data transmission
Before any data transfer operation is initiated, it is critical to properly prepare both devices. On the old smartphone from which the export will be made, you need to make sure that all contacts are stored in the device memory or on the device. SIM-The new Xiaomi Redmi Note should enable the wireless module in advance and make the device visible to external search.
The process of activating visibility on Android usually requires switching to Bluetooth settings. It is important to understand that just switching on is not enough: the system must allow detection by the device within a certain time, usually 2-5 minutes. If the screen goes out or the device goes into sleep mode, visibility may be lost and the procedure will have to start again.
Make sure both smartphones are geolocated. In modern versions of Android (starting at 6.0 and up), scanning Bluetooth devices is closely linked to work. GPS-Without active permission to access the location, your Redmi Note may not see the old phone in the list of available devices, which will cause confusion among inexperienced users.
⚠️ Note: When pairing devices, pay attention to the digital code that appears on the screens of both smartphones. If the codes do not match, the pairing process cannot be interrupted, as this can lead to a security error or connection to someone else's device in crowded air.
Export contacts to vCard format on the original device
The key step before direct transmission is to form a container file. In the Android ecosystem, the de facto standard for storing contacts is the vCard format (.vcf extension), which allows you to package not only the name and number, but also additional fields: addresses, emails, photos and notes, keeping the data structure unchanged during transfer.
To create such a file, you need to open the Contacts app on your old phone. The control menu (often three dots in the corner or the "More" button) should select the "Import/Export" or "Contact Management" option, then select the "Export to Device Memory" or "Export to.vcf" action. The system will suggest you choose a save location; by default, this is an internal memory or a root directory.
Once the export is complete, a file will appear in the phone's memory, commonly called 00001.vcf or contacts.vcf. This is the object that will be transmitted. If the phone book is large, the system can create multiple files or one large archive, which is perfectly normal for subsequent transfer via Bluetooth, the size of such a file, even for a thousand contacts, rarely exceeds a few megabytes.
The process of pairing and transferring a file
Direct data transfer starts with a search for the recipient device. On the new Xiaomi Redmi Note, go to Bluetooth settings and wait for the old phone's name to appear in the "Available Devices" list. By clicking on the name, you initiate a pairing request. Both screens will have a confirmation request — it must be accepted on both devices simultaneously.
Once the pairing is successful, the status will change to Connected. Now, on the old device, you need to find the previously formed contact file through the file manager. Select the.vcf file, select the Share option and select Bluetooth from the list of available protocols. The system will suggest selecting the recipient device - select your Redmi Note.
The receiving device will pop up a file request window. You need to confirm reception. The transfer speed depends on the Bluetooth version and the distance between the devices. For hundreds of contacts, the process can take from 30 seconds to several minutes. It is strongly discouraged to interrupt or turn off the device screens at this point.
☑️ Transfer checklist
Import contacts to Xiaomi Redmi Note
Once the transfer is complete, the file is saved to the Downloads or Bluetooth folder on the new smartphone. However, just having a file does not mean that the contacts have appeared in the phone book. The MIUI system (the Xiaomi shell) requires manual initiation of import from the received file.
Open the standard Contacts app on Xiaomi. Select Import/Export contacts from the menu, then select the source, in this case Import from storage, and automatically scan the memory and find the transmitted.vcf file.
At the last stage, the system will ask where to keep contacts: SIM-The most reliable option is to choose a Google account, as this provides synchronization and protection against data loss in the event of a device breakdown. Once you select the target storage, the process of reading the file and adding records to the database will begin.
| Parameter | Phone memory | SIM-map | Google account |
|---|---|---|---|
| Limit of records | Depends on memory. | Usually 250. | No restrictions. |
| Photo preservation | Yes. | No. | Yes. |
| Synchronization | No. | No. | Automatic. |
| Supplementary fields | All fields. | Name and number only | All fields. |
Solving typical transmission problems
Despite the simplicity of the protocol, users often face technical difficulties, and one of the most common problems is "Device not found." This often involves the cache of a Bluetooth service, in which case it helps to clear the cache of the Bluetooth application in the application settings or simply restart both smartphones, which resets the errors of the communication stack.
Another common error is “File is not supported” or “Imported failed.” This can occur if the contact file is corrupted during transmission or has a non-standard encoding, in which case it is recommended to try transferring the file through a file manager rather than a standard interface, or to break the phone book into several smaller files before sending.
If the process is stuck in the “Send...” phase, check the battery level. Xiaomi’s energy-saving algorithms can aggressively limit background Bluetooth activity at low charge. Also make sure there are no metal barriers or sources of strong radio interference between the devices, such as a running microwave oven.

Alternative methods and conclusion
While Bluetooth is a reliable tool, it can be slow to transfer huge amounts of data (thousands of contacts with photos), and Xiaomi owners should pay attention to the built-in Mi Mover app. It uses Wi-Fi Direct and allows you to transfer not only contacts, but also applications, settings and media files many times faster, creating a direct connection between devices.
However, knowing the classic method via Bluetooth remains an important skill: it doesn’t depend on the MIUI version, whether you have a Mi or Google account in the setup stage, and works even on the most budget-friendly Redmi models without Internet access.
When you finish the process, be sure to check the integrity of the data. Go through the contact list, make sure the numbers are displayed correctly, and the names are not turned into a character set. If everything goes well, the old.vcf file can be deleted to free up space, since the data is now securely secured in the new system.
💡
Expert advice: Before starting a large-scale transfer, try sending a test contact (e.g. yourself) with a minimum set of fields to make sure the encoding and import path are set up correctly without risking the entire database at once.
💡
Using Bluetooth to transfer contacts is a versatile, secure and internet-free way, ideal for fast mobile phone book migration between any Android device.
