Changing a smartphone is always an exciting process, which is often overshadowed by the fear of losing important information. The most valuable asset for most users is their phone book, which contains the numbers of friends, colleagues and business partners. The loss of this data can paralyze business activity and personal communication, so the issue of migration comes first before activating a new device.
Fortunately, the ecosystem Android offers many built-in and third-party tools for seamless data transfer. You don't have to manually search through hundreds of numbers or frantically search through old notebooks. Modern methods allow you to clone the entire database in a matter of minutes, while preserving the group structure, contact photos and additional notes.
In this guide, we will examine in detail all the current transfer methods, from cloud synchronization to using the good old one. Bluetooth. We will look at the nuances of working with Google account, features of exporting through files VCF and specific functions of manufacturers like Samsung Smart Switch or Xiaomi Mi Mover. The correct choice of method depends on the condition of your old device and the availability of Internet access.
Synchronization via Google account: the most reliable method
The most preferred and modern method is synchronization through cloud services Google. This method ensures that your contacts will be safe even if both phones physically break. To get started, make sure that you are logged into your main Gmail mailbox on your old device.
Go to your phone settings and find the Accounts or Users and accountssection. Select your Google profile and make sure the slider next to Contacts is activated. If the switch is turned off, turn it on and click the "Sync" button. This action will send all local records to the corporation's servers.
After the data download is complete, take a new smartphone. During initial setup, simply enter the same login and password for your Google account. The system will automatically add all saved numbers to the local phone book of the new device. This process occurs in the background and does not require user intervention.
⚠️ Attention: If on your old phone contacts are saved exclusively in the device memory or on the SIM card, and not in your Google account, automatic synchronization will not work. First, you need to manually export to the cloud.
Before buying a new phone, go to your contacts on your old device and check where exactly they are saved. The best option is a “Google Account”, as this provides instant access from any device.
Export and import via VCF file
Sometimes using the Internet is impossible or undesirable for privacy reasons. In such cases, the old proven method using a business card file comes to the rescue. This universal format is supported by absolutely all operating systems and applications for working with the address book. .vcf. This universal format is supported by absolutely all operating systems and applications for working with the address book.
Open the Contacts application on your old device. From the menu (usually three dots in the corner), select "Manage contacts" or "Import/export". You need to select the "Export to .vcf file" or "Export to storage" option. The system will create a single file containing your entire phone book.
Next, this file needs to be transferred to a new phone. This can be done through instant messengers, email, or simply by connecting the phone to the computer as a flash drive. On a new device, open the received file - the system will offer to import data into an existing database or create a new one.
- 📂 The file
.vcfmay contain not only numbers, but also addresses, birthdays and photos. - 🔄 When importing a large file (more than 1000 contacts), the process may take several minutes.
- 💾 It is recommended to store a backup copy of the file on your computer or in a cloud drive.
It is important to understand the difference between data storage. If you export contacts that are physically on a SIM card, the file may be truncated because the SIM card's memory is limited and does not support long names or additional fields. Always try to copy data from the phone memory.
☑️ Preparing to export VCF
Using a SIM card for transfer
This method is considered obsolete, but it remains the only working option if the old phone is broken, does not turn on, or is a push-button device without support for modern data transfer standards. The SIM card acts as a physical storage medium.
On your old device, go to the contacts settings and select the “Copy to SIM card” function. Be prepared that the number of stored numbers is limited by the capacity of the chip (usually from 200 to 500 records). Also, names may be trimmed to 10-12 characters due to technical limitations of the storage format on the SIM card.
After copying, remove the card and insert it into a new one Android-smartphone. Go to the contacts application, select the import menu and select the source "SIM card". The system will prompt you to select an account to save where the data will be copied. After completing the procedure, the contacts will appear in the memory of the new phone.
| Parameter | Phone memory | Google Account | SIM card |
|---|---|---|---|
| Contacts limit | Thousands | 25 000+ | 200-500 |
| Saving photos | Yes | Yes | No |
| Additional. fields (email) | Yes | Yes | No |
| Network dependence | No | Yes | No |
Why are names truncated on the SIM card?
The standard for storing data on SIM cards was developed several decades ago and has strict restrictions on the length of the name string (usually 14 bytes). Modern smartphones ignore these restrictions when stored in memory, but when writing to a SIM card they are forced to adapt to the old standard.
Branded utilities from smartphone manufacturers
Large vendors, such as Samsung, Xiaomi, Huawei and others, develop their own applications for data migration. These tools are often the most convenient, as they allow you to transfer not only contacts, but also SMS, call logs, Wi-Fi settings and even the arrangement of icons on the desktop.
For devices Samsung use the application Smart Switch. It is available on Google Play for any Android smartphone, but it reveals its fullest potential when transferring data between two Samsung devices. The connection can be made via a USB-C to USB-C cable or via Wi-Fi Direct.
Users Xiaomi and Poco can use the built-in application Mi Mover. It works on a similar principle: on the old phone the “Sender” mode is selected, on the new one – “Recipient”. The devices scan the QR code to create a secure communication channel and begin transmitting data packets.
The main advantage of such utilities is their deep integration with the system. They can even transfer data between different versions of Android, automatically converting settings formats if necessary. This saves the user from manually setting each parameter in a new location.
⚠️ Attention: When using wireless transmission through proprietary utilities, make sure that both phones are charged at least 50%. The process can be energy-intensive and drain the battery of an old device to a critical level.
Third-party applications for migration
If the built-in tools for some reason are not suitable or do not work correctly, you can use solutions from independent developers. The store Google Play presents many applications that specialize exclusively in transferring contacts and media files.
One of the popular solutions is the application Copy My Data. It works by connecting both phones to the same Wi-Fi network. The app scans the network, finds the second device and allows you to select the types of data to transfer. The interface is as simplified as possible and understandable even for beginners.
Another option is to use file managers with a backup function, such as Super Backup. These apps create a complete copy of your contacts database as a file, which you can then restore to any device. They often offer an automatic scheduled backup feature.
When choosing third-party software, pay attention to the permissions that the application requests. To work with contacts, he really needs access to the phone book, but a request for access to the microphone or geolocation should alert him. Always download apps only from the official application store.
Third-party applications are an excellent solution if you change your phone between different brands (for example, from Huawei to Samsung), where proprietary utilities may be incompatible.
Solving common problems and errors
During the process of transferring data, users may encounter various technical issues failures. One common problem is the appearance of duplicate contacts. This happens when you import data on top of an existing synchronized database.
To eliminate duplicates, modern versions of Android have a built-in merging function. Go to the Contacts app, open Settings and find Manage Contacts → Merge Duplicates. The system will analyze the database and offer to merge records with the same names or numbers.
Another problem is the absence of some contacts after the transfer. This is often due to the fact that on the old phone the numbers were saved in instant messengers (for example, in Telegram or WhatsApp bookmarks) or in the SIM card memory, which they forgot to check. It's also worth checking the display filters in the contacts app - contacts without numbers or from certain accounts may be hidden.
If the transfer is interrupted in the middle, try turning off power saving on both devices. Power saving mode can aggressively shut down background data transfers, breaking the connection between phones. Also make sure that geolocation is enabled on both devices, as it is required for the Wi-Fi Direct protocol to work.
⚠️ Attention: Settings interfaces and menu item names may differ depending on the version of Android and the manufacturer's shell (MIUI, OneUI, ColorOS). If you do not find the item you need, use the search in your phone settings.
☑️ Diagnosis of transfer problems
Frequently asked questions (FAQ)
Will photos linked to contacts?
Yes, when using Google synchronization, export to VCF or proprietary utilities, photos are saved. However, when transferred via a SIM card, the images will be lost, since this medium does not support graphic data.
What should you do if the contacts are displayed in hieroglyphs on a new phone?
This is an encoding problem that is rarely encountered on modern Android, but is possible when importing from very old devices. Try opening the VCF file on your computer in a text editor and saving it in UTF-8 encoding, then repeat the import.
Is it possible to transfer contacts if the screen of your old phone is broken?
If the sensor does not work, but there is an image, connect a USB mouse via an OTG cable for control. If the screen is black, but the phone is working, try connecting to it from a computer via USB debugging or remove the SIM card if the numbers are there.
How long does it take to transfer 1000 contacts?
When using cloud synchronization or Wi-Fi Direct, the process takes from 1 to 5 minutes depending on the Internet speed and the presence of photos of the contacts. Via Bluetooth this can take up to 15-20 minutes.
Do you need to delete contacts from your old phone after transferring?
No, it is not necessary. A transfer creates a copy of the data rather than moving it. You can reset your old phone to factory settings only after you make sure that all data is displayed correctly on the new device.
