Changing a mobile device almost always causes a slight panic associated with the fear of losing important information. Among all the data stored in the gadget’s memory, contacts are the most critical for everyday life and work. Losing the number of a colleague, doctor or close friend is much more painful than losing a couple of downloaded games or wallpaper settings.

Fortunately, the ecosystem Android offers many built-in and third-party solutions for data migration. Modern smartphones from Samsung, Xiaomi, Huawei and other manufacturers have pre-installed tools that make the process almost automatic. However, it is important to understand the differences between methods in order to choose the best one for your specific situation.

In this article we will analyze in detail all the current methods of transferring a phone book. We will consider both cloud synchronization, which requires an account, and local transfer methods without using the Internet. You will learn how to avoid duplicating records and what to do if standard methods do not work.

Synchronization through a Google account: the most reliable method

The most universal and recommended method is to use cloud storage Google Contacts. This method ensures that your phone book will be accessible from any device; you just need to enter your username and password. The data is stored on the corporation's servers, which prevents its loss in the event of a physical breakdown of the smartphone.

To start the procedure, you need to make sure that synchronization is enabled on your old device. Go to the system settings, find the section Accounts or Users and accounts. Select your Google profile and make sure the switch next to Contacts is active. If it is turned off, turn it on and wait for the synchronization to complete.

After that, take a new smartphone and log into the same one Google account. The system will automatically pull up all saved numbers from the cloud. Typically this process takes from a few seconds to a couple of minutes, depending on the number of entries and the speed of the Internet connection.

  • 🔄 Automatic update: any changes on one device are instantly displayed on all others.
  • ☁️ Memory independence: contacts do not take up space in the internal storage phone.
  • 🔒 Security: access to data is protected by two-factor authentication.
  • 🌐 Web interface: the ability to edit numbers directly through the browser on your computer.

⚠️ Attention: Before buying a new phone, make sure that the contacts are saved in your Google account and not in the phone memory or SIM card. Entries stored locally (“Only on the device”) are not automatically synchronized.

💡

Using a Google account is the only way that allows you to restore contacts even if your old smartphone is completely lost or stolen.

Export and import via VCF file (business card card)

If you do not have access to the Internet or do not want to use cloud services, creating a backup file is an excellent solution. In the Android system this format is called VCF (vCard). It is a single file containing all the information about your contacts, including names, numbers, email addresses and even photos.

To create such a file, open the Contacts application on your old phone. In the settings menu (often hidden behind three dots in the corner of the screen), select Import/export contacts. Next, click Export to .vcf file. The system will prompt you to select a save location, usually this is internal memory in the downloads folder.

The resulting file must be transferred to a new device. This can be done via instant messengers, email, Bluetooth, or simply by copying the file to your computer and then to a new phone. On the receiving device, just open the VCF file, and the system will offer to import all found entries into the phone book.

💡

When exporting a large number of contacts (more than 500), the file can become quite large. In this case, it is better to use Wi-Fi Direct or a cable rather than Bluetooth for faster transfer.

This method is especially useful when moving between devices of different ecosystems, for example, if you are temporarily using a phone on a different platform. The VCF file is a universal standard that is understood by almost all modern operating systems.

Using a SIM card to transfer data

Although this method is considered outdated, it is still relevant in situations when the smartphone does not turn on, and information needs to be retrieved urgently. SIM card has its own small memory capable of storing basic information about contacts. However, this method has significant limitations in terms of data volume and format.

The copying process to SIM begins by opening the contacts application on the old device. In the control menu, select the option Copy contacts or Export to SIM card. You will be asked to select sources (for example, Google account or phone memory) and check the boxes for the entries you want to transfer.

After copying is complete, move the SIM card to the new smartphone. In the Contacts application of your new device, go to settings and select Import from SIM card. The system reads the data and will offer to save it to the selected storage, for example, to phone memory or a cloud account.

Characteristics SIM card memory Phone memory / Google
Maximum number Usually up to 250 records Unlimited
Name length Limited (often truncated) Full support for long names
Add. fields Number and name only Photo, email, address, notes
Reliability Low (risk of chip damage) High (backup)

⚠️ Attention: When importing from a SIM card, additional numbers (work, mobile, home) are often lost, since the card only supports one field for phone. All second numbers may be recorded as a note or lost.

Why may contacts not be displayed after rearranging the SIM?

Sometimes new smartphones hide contacts stored on the SIM card by default, so as not to clutter the list. Go to the contact display settings and make sure that the checkbox next to “SIM card” is active.

Applications from smartphone manufacturers

Large vendors understand the importance of seamless migration for their clients, so they develop their own utilities for data transfer. Applications such as Samsung Smart Switch, Xiaomi Mi Mover or Huawei Phone Cloneallow you to transfer not only contacts, but also messages, photos, system settings and even the home screen layout.

The operation of these applications is usually based on creating a direct wireless connection between two devices. You need to install the application on both smartphones (new ones often have it pre-installed). Launch the app, select the “Sender” role on one device, and “Recipient” on the other.

Scanning a QR code or connecting via a Wi-Fi access point will unite gadgets into a single network. Next, you can select categories of data to transfer. The process is much faster than via Bluetooth, since a high-speed data transfer protocol is used.

  • 📱 Full copy: not only the phone book is transferred, but also the call history.
  • High speed: transfer gigabytes of data in a matter of minutes.
  • 🛠 Saving settings: alarm clocks, wallpapers and Wi-Fi settings are transferred automatically.
  • 🔋 Energy efficiency: less battery consumption compared to constant downloading from the cloud.
📊 Which method do you most often transfer data?
Via Google account
VCF file
Manufacturer's application
SIM card
Bluetooth

It is worth noting that some features may not be available when switching between devices of different brands. For example, specific interface settings One UI from Samsung will not be applied to the phone Xiaomi. However, basic data such as contacts and media files are transferred without problems, regardless of brand.

Transfer via Bluetooth and Nearby Share

For transferring a small number of contacts or in situations where other methods are not available, you can use Classic Bluetooth. In modern versions of Android, this technology has evolved into a function Nearby Share (Close sharing), which works similar to Apple's AirDrop, providing higher speed and convenience.

To send a contact via Bluetooth, open an entry in the phone book. Click on the menu (three dots) and select Share. Select the Bluetooth icon from the list of available methods. On the receiving device, you must confirm the request to pair and receive the file.

The function Nearby Share works even easier. It automatically searches for nearby devices that have Bluetooth and geolocation enabled. You don't need to do manual pairing. Just select a contact, click “Share” and tap on the Nearby Share icon, then select a device from the list.

Sequence of actions for Nearby Share:

1. Open a contact.

2. Click "Share".

3. Select "Nearby Share".

4. Confirm receipt on the second device.

⚠️ Attention: For Nearby Share to work, the screen must be turned on on both devices and the phone must be unlocked. Also make sure that the visibility settings are set to “All contacts” or “Some contacts” and not “Hidden”.

Solving problems with duplicates and merging

A common problem after transferring contacts is the appearance of duplicates. This happens when the same entry is saved simultaneously in the phone memory, on the SIM card and in the Google account. The system sees them as different objects because they have different unique identifiers in the database.

Fortunately, modern smartphones have built-in tools for clearing the list. Google's Contacts app or manufacturers' shells often have a function Contact management or Merge duplicates. The algorithm automatically finds records with the same names or numbers and offers to merge them into one card.

If automatic merging does not work, you can use the web version of Google Contacts. Visit contacts.google.com from your computer. In the menu on the left, find the section Merge and correct. The service will show a list of potential duplicates and allow you to combine them en masse in one click.

☑️ Checking the quality of the transfer

Completed: 0 / 5

Regular cleaning of the phone book not only improves visual perception, but also speeds up the search. A database with thousands of duplicate entries may not work correctly when trying to find the desired number through the system's global search.

Frequently asked questions (FAQ)

What to do if contacts do not sync with Google?

First of all, check your Internet connection. Then go to your account settings and try unchecking contact synchronization, wait a couple of seconds and turn it on again. If this does not help, delete the account from the system and add it again, after making sure that the data is saved on the server via the web interface.

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 trust in the computer was previously established, you can use apps to control Android from a PC (for example, ADB or specialized software). You can also remove the SIM card if the numbers were stored on it, or connect the phone to the monitor via USB-C (if the model supports video output) and control it with the mouse.

Is it safe to use third-party applications for transfer?

Most popular applications from the official store Google Play are safe. However, avoid apps that require suspicious permissions, such as SMS or microphone access to simply transfer contacts. It is better to use official utilities from manufacturers or built-in system tools.

How long does it take to transfer 1000 contacts?

When using cloud synchronization or a VCF file, the process takes from 30 seconds to 2 minutes. When transferring via Bluetooth, this may take 5-10 minutes. Branded utilities cope with this volume in a matter of seconds, since most of the time is spent establishing a connection rather than transferring text.
