Changing a mobile device is always a little stressful, associated not so much with getting used to a new gadget, but with the need to restore the digital environment. The most critical element in this process is often telephone directorycontaining hundreds of important numbers of colleagues, friends and delivery services. The loss of this data can paralyze business activity or personal communication, so the issue of their safe migration comes first when purchasing a new smartphone.
Fortunately, the ecosystem Android offers many built-in and third-party tools to solve this problem without losing information. Modern versions of the operating system automatically create backups in the cloud, but older models or specific settings may require manual intervention. In this article, we will analyze in detail all the available methods, from cloud synchronization to physical file transfer, so that you can choose the best option for your situation.
We will consider the nuances of each method, possible errors and ways to eliminate them. Regardless of whether you switch from Samsung to Xiaomi or from Google Pixel to OnePlus, the principles of working with the contact database remain universal, although the interfaces may differ slightly.
Synchronization through a Google account: the most reliable method
The most effective and modern way to save a contact book is to link to an account Google. This method ensures that your data is not only transferred to the new phone, but also protected from physical loss of the SIM card or damage to the device. The synchronization process occurs in the background and does not require constant user interaction after the initial setup.
First, you need to make sure that contact synchronization is enabled on your old device. Go to your phone settings, find the section Accounts and synchronization or Users and accounts. Select your Google profile and check if the "Contacts" checkbox is checked. If the switch is turned off, activate it and wait until the update process is completed.
After the data is sent to the cloud, we move on to the new smartphone. When you turn on the device for the first time, the system will prompt you to enter your account information. Use the same email address as on the old phone. After authorization, the system will automatically pull all saved numbers into the local phone book of the new gadget.
⚠️ Attention: If you use several Google accounts, make sure that the contacts are saved in exactly the profile that you plan to use on the new device. Contacts saved in the phone memory or on the SIM card are not automatically synchronized.
Sometimes a situation arises when contacts do not appear immediately. In this case, it is worth checking the display settings in the Contacts application. It is possible that the filter is set to only display numbers from the SIM card. Change the setting to "All contacts" or select a specific Google account to display.
Before purchasing a new phone, visit contacts.google.com from your computer. If you see all your numbers there, it means that the synchronization was successful and the data is securely saved in the cloud.
Export and import via VCF file
Export method to file format VCF (vCard) is a universal solution that works even without access to the Internet. This method is ideal for bulk transfer of a large number of records between devices from different manufacturers, where cloud services may not work correctly or be unavailable.
The process begins on the old device. Open the Contacts app, tap the menu (usually three dots or lines) and select Manage Contacts or Import/Export Contacts. We need a function Export to .vcf file. The system will prompt you to select a save location: internal memory or SD memory card.
After creating the file, it must be transferred to the new phone. This can be done in several ways:
- 📤 Send the file via instant messengers (Telegram, WhatsApp) to yourself.
- 📧 Send the file as an attachment by email.
- 📂 Copy the file to your computer, and then transfer it to a new smartphone via a USB cable.
- 📡 Use fast transfer technologies, such as Nearby Share or Quick Share.
On the receiving device, just open the received file. The Android system will automatically recognize the vCard format and offer to import the content into the phone book. You can choose which account to save the data in: to the phone's local storage or to a Google account for future synchronization.

Using a SIM card for transfer
Although this method is considered obsolete due to serious limitations, it is still the only working option for very old phone models or in emergency situations when other methods are not available. The main limitation of a SIM card is the amount of memory and data storage format.
Most modern SIM cards can store no more than 250–500 contacts. In this case, only the name and one phone number are saved. Additional fields, such as address, email, contact photo or second number, will be irretrievably lost when copied to the card.
To perform the transfer, go to the contacts settings on your old phone and select the function Copy from phone to SIM card. The process may take some time depending on the number of entries. Once completed, remove the card and insert it into the new smartphone.
On the new device, go to the contacts application, select the import menu and specify the source SIM card. The system will prompt you to select a target folder for saving - it is recommended to immediately select a Google account so as not to depend on physical media in the future.
⚠️ Attention: When copying to a SIM card, long names may be trimmed to 10-12 characters. It is also possible that duplicates may appear if old entries have already been saved on the card.
Data transfer applications from manufacturers
Large smartphone manufacturers are developing their own utilities for seamless data migration, which are often more convenient than standard Android tools. These applications allow you to transfer not only contacts, but also call history, SMS, installed applications and even the desktop layout.
For devices Samsung the application is used Smart Switch. It allows you to connect two phones via a USB-C-to-C cable or over Wi-Fi. The process is fully automated: you simply select the type of data to transfer and press the start button.
Smartphone owners Xiaomi, Redmi and Poco can use the utility Mi Mover. Similar solutions exist for other brands: Clone Phone for OnePlus and Realme, Phone Clone for Huawei. The principle of operation is similar: on the old phone the “Sender” mode is selected, on the new one - “Recipient”, after which the devices are connected via a QR code.
Why are manufacturers' applications better than standard ones?
Proprietary utilities have access to deep system settings, which allows you to transfer data hidden from third-party applications, for example, alarm clocks, alarm settings and Wi-Fi passwords.
The use of such apps minimizes the risk of user error. The interface is usually intuitive and contains step-by-step tips. However, it is worth considering that for some functions to work, both devices must be plugged in or have a high battery charge.
Solving problems with duplicate contacts
A common problem after data transfer is the appearance of duplicate records. This happens when the same contact is saved in the phone memory, SIM card and Google account at the same time. The presence of duplicates makes it difficult to find the desired number and clogs the device's memory.
Modern versions of Android have a built-in tool for merging records. In the Contacts app, find the "Manage Contacts" section and select the Merge duplicates or "Merge and Export" option. The system will automatically scan the database, find records with the same names or numbers and offer to merge them.
If the automatic merge did not work correctly, you can use the web version of Google Contacts. On your computer, log into your account and select “Merge and Fix” in the menu on the left. There you will see a list of all found duplicates and can manually confirm their merging.
| Transfer method | Speed | Saving photos | Network dependence |
|---|---|---|---|
| Account Google | High | Yes | Required |
| VCF file | Medium | Yes | Not required |
| SIM card | Low | No | Not required |
| Applications (Smart Switch) | Very high | Yes | Not required (Wi-Fi Direct) |
Regular cleaning of duplicates not only frees up space, but also speeds up the phone book search, making it more responsive.
Frequently asked questions (FAQ)
What to do if contacts are not synchronized with Google?
Check your Internet connection and make sure that synchronization for contacts is enabled in your account settings. Also try deleting and adding the account again, after making sure that the data is saved in the VCF file.
Is it possible to transfer contacts if the screen of the old phone is broken?
Yes, if the phone had USB debugging mode enabled or synchronization with the cloud was previously configured. Otherwise, you will need to connect a mouse via a USB-OTG adapter to control the device and create a backup.
Is it safe to transfer contacts via Bluetooth?
Transferring individual contacts via Bluetooth is safe, but for bulk transfer of hundreds of numbers this method is extremely inconvenient and slow. It is better to create one common VCF file and transfer it.
Where is it better to save contacts: to your phone or to the cloud?
Definitely to the cloud (Google account). If your phone is lost or broken, you will instantly restore the entire database on any other device by simply entering your username and password. Local storage carries a high risk of data loss.
