Buying a new smartphone series Samsung Galaxy is always accompanied by pleasant anticipation, but the process of data migration often raises questions. A particularly critical point is the preservation of the phone book, because the loss of important numbers can lead to serious inconvenience in work and personal life. Fortunately, the ecosystem Android and the Korean giant's proprietary utilities offer many reliable ways to solve this problem.
There are several proven methods for syncing contacts, each of which has its own advantages depending on the source device and your preferences. You can use cloud services, a physical SIM card, a direct connection via Wi-Fi, or even the good old Bluetooth. In this article, we will analyze each action algorithm in detail so that you can choose the best option for your situation and complete the transfer without losing data.
Before you begin active actions, make sure that both devices are charged at least 50-60%. This is a basic security requirement that will allow you to avoid interruption of the data transfer process at the most critical moment. It is also recommended to check the availability of free space in the internal memory of the new device.
Using the Smart Switch application for complete migration
The most effective and modern way to transfer information between smartphones is a proprietary utility Samsung Smart Switch. This application is pre-installed on all new devices of the brand and is available for download on other Android and even iOS models. The app allows you to broadcast not only contacts, but also photos, messages, system settings and installed applications in a holistic form.
To get started, you need to launch the application on both devices. On the new phone, select the “Receive data” mode, and on the old phone, select “Send data”. The system will automatically prompt you to select a connection method: wireless connection, USB cable or external drive. The wireless method is the most convenient, as it does not require searching for adapters, but the cable provides higher speed and stability when transferring large amounts of information.
After the connection is established, you will be asked to select the types of data to transfer. In the list of available options, be sure to check the item Contact. You can deselect (uncheck) other categories if you plan to set up a new phone from scratch, leaving only the phone book. The synchronization process will take from a few seconds to a couple of minutes depending on the number of records in your database.
- 📱 Make sure that Wi-Fi and Bluetooth are turned on on both devices for a wireless connection.
- 🔌 If using a cable, you may need a USB-C to Micro-USB or Lightning adapter.
- ✅ Confirm permission to access data on the old device in a pop-up window.
- 🔄 Do not minimize the Smart Switch application until the copying process is complete.
⚠️ Attention: When transferring data via Smart Switch from an Android device to Samsung, duplicate contacts may be automatically merged, but it is recommended to check the phone book after the procedure is completed.
☑️ Preparing to work with Smart Switch
Synchronization via Google account: cloud method
If your previous device ran Android, then your contacts are most likely already saved in cloud storage Google. This is the most reliable method, which does not depend on the physical condition of the SIM card or the availability of cables at hand. The entire phone book is linked to your Gmail account and is automatically downloaded to any device after entering your username and password.
To use this method, first check the settings on your old phone. Go to the section Settings → Accounts and archiving → Account management. Select your Google profile and make sure that the switch next to Contact is active. If synchronization was disabled, turn it on and click the “Synchronize” button to make sure that all numbers are uploaded to the company’s servers.
On a new smartphone Samsung the procedure is even simpler. During initial setup, the system will prompt you to enter your Google account information. After successful authorization, the phone will automatically begin to retrieve all saved data, including the phone book. If the device is already set up, you can add an account manually through the settings menu, and the contacts will appear in the Contacts application within a few minutes.
What to do if the contacts do not appear?
Sometimes forced synchronization is required. Go to Settings → Accounts → Google, click on the three dots in the corner and select “Sync.” Also check whether contacts are hidden in the phone book application itself through the filter menu.
Therefore, before buying a new gadget, you should audit your phone book and, if necessary, export local entries to the cloud.
Synchronization via Google is the “gold standard” for Android users, providing automatic backup and instant access to numbers from any devices.
Transferring contacts via SIM card: classic option
Despite the development of cloud technologies, the transfer method via a physical SIM card remains relevant, especially when switching from old push-button phones or devices not connected to the Internet. This method is universal and works regardless of the brand of smartphone, but has significant limitations on the amount of information stored.
First, you need to export contacts on your old device. Go to the Contacts application, open the control menu (usually three dots or the More button) and select Import/Export contacts. In the menu that appears, select the “Export to SIM card” option. The system will warn you about the possible loss of some data if the record contains additional fields not supported by the SIM standard.
⚠️ Attention: The SIM card has a limited memory capacity (usually up to 250 numbers) and does not support saving photos, email addresses and long names. Long names may be truncated during recording.
After the export is complete, remove the card from the old phone and insert it into the new one Samsung Galaxy. If the sizes do not match, use an adapter or contact a communication store to replace the card with a Nano-SIM format without losing data. On your new device, go back to the Contacts app, select Import/Export, and tap Import from SIM. You will be asked to select a storage location: we recommend choosing a Google account or the internal memory of the phone, and not the SIM card itself.
| Characteristics | SIM card | Google Account | Smart Switch |
|---|---|---|---|
| Transfer speed | Low | High | Very high |
| Saving photos | No | Yes | Yes |
| Internet required | No | Yes | Only for downloading the application |
| Contact limit | ~250 pcs. | Unlimited | Unlimited |
This method is ideal for quickly transferring a basic list of numbers when other methods are not available. However, for a complete migration of a modern phone book with avatars and groups, it is better to use digital methods.
Import via VCF file: universal format
Format VCF (vCard) is a universal standard for storing contact information. In fact, this is a text file containing structured data about each subscriber. This method is especially useful if you need to transfer contacts from iPhone to Samsung or if you want to create a physical backup on a computer or flash drive.
On the source device, export contacts to a file. In the phone book menu, select the “Export” option and specify the storage location - internal memory or microSD card. The system will create a file with the extension .vcf, which can contain either one contact or the entire phone book in the form of one archive. The file name is usually generated automatically, for example 00001.vcf or contacts.vcf.
Next you need to transfer this file to a new smartphone Samsung. This can be done in any convenient way: send it to yourself by email, send it via instant messenger, use Bluetooth, or simply copy the file to your computer and then to a new phone via cable. Once the file is in the internal memory of the new device, simply click on it in the file manager.
The system will automatically recognize the format and offer to open it through the Contacts application. Confirm the import and all entries from the file will be added to your phone book. If the file contains duplicates of existing numbers, the system may offer to merge them or create new records.
Before importing a large VCF file, it is recommended that you make a copy of it on your computer. This will avoid data loss if the recording process on a new device fails.
Using Bluetooth for transfer without the Internet
In situations where there is no cable at hand, there is no access to Wi-Fi, and the amount of data is small, technology comes to the rescue. Bluetooth. Although the transfer speed of this protocol is much lower than that of Wi-Fi Direct, it is quite enough to send one phone book file. The method requires minimal preparation and works on the vast majority of mobile devices.
Activate Bluetooth on both phones through the notification shade or in the settings. Pair your devices: on one of them, find the name of the other in the list of available devices and click on it to connect. You may need to confirm the pairing code on both screens. Make sure the connection status shows as “Connected.”
Go to the contacts application on your old phone, highlight all the required entries or select the “Select All” option from the menu. Click the Share button and select the Bluetooth icon from the list of available methods. Indicate your new smartphone Samsungas the recipient. The receiving side will ask you to confirm receipt of the file - agree to it.
After the transfer is completed, the file will automatically open or be saved in the downloads folder. As with the VCF method, all you have to do is confirm the import of data into the phone book. This method is good for its autonomy, but can be slow when transferring several thousand contacts with photos.
⚠️ Attention: When transferring via Bluetooth, make sure that the screens of both phones do not go dark and the connection is not broken. Interrupting the transfer can lead to damage to the VCF file.
Solution: duplicates and missing numbers
After completing the transfer procedure, users often encounter two main problems: duplicate entries or missing numbers. Duplicates occur when the same contact is saved on the SIM card, phone memory and Google account at the same time. Modern versions of the shell One UI Samsung have built-in tools to solve this problem.
To merge duplicates, open the Contacts application, click on the menu (three horizontal lines) and select Contact management. Next, find the “Merge duplicate contacts” option. The system will analyze the database, find records with the same names or numbers and offer to combine them into one card, summarizing all available information (photos, mail, addresses).
If some numbers are not displayed, check the display settings. From the Contacts menu, select Display Settings or Contacts to Display. Make sure that the “All contacts” checkbox is checked or that the exact accounts (SIM, Phone, Google) where the import was made are selected. Sometimes contacts are simply hidden by a filter and not deleted.
Regularly cleaning duplicates and checking display settings is a mandatory step after data transfer, ensuring order in the phone book.
In rare cases, especially when switching from specific models of other brands, some contact fields may not be read correctly. If you notice that the missing numbers had notes or specific ringtones saved, this information may not have been transferred due to differences in database formats. In such a situation, all that remains is to manually fill in the missing details.
⚠️ Attention: The menu interface and item names may vary slightly depending on the version of Android and the One UI shell. If you do not find the specified option, use the search in the settings.
Frequently asked questions (FAQ)
Is it possible to transfer contacts if the old phone does not turn on?
If the phone does not turn on, but the SIM card is working, you can insert it into the new device and import the numbers, saved on the card. If the contacts were in the phone's memory, it is almost impossible to restore them without turning on the device, unless they were synchronized with a Google account in advance.
Is it safe to transfer contacts through third-party applications?
Using proprietary utilities such as Smart Switch is completely safe. Third-party apps from untrusted sources may pose a privacy risk by accessing your personal phone book. It is recommended to use only proven system tools.
What to do if contacts were imported with hieroglyphs instead of letters?
This problem occurs due to an encoding mismatch when importing a VCF file. Try opening the file on your computer using Notepad and saving it in UTF-8 encoding, then import again. Also make sure that both phones are set to the same system language.
How long does it take to transfer 1000 contacts?
When using Smart Switch or Google synchronization, the process takes from 30 seconds to 2 minutes. Transferring via SIM card or Bluetooth may take from 5 to 15 minutes depending on the card's writing speed and Bluetooth protocol version.
Do you need to delete contacts from your old phone after the transfer?
No, this is not necessary. However, if you plan to sell or give away your old device, it is recommended to perform a Factory Reset to delete all personal data, including contacts, photos and messages, before transferring it to the new owner.
