Changing a smartphone is always an exciting process, which is often overshadowed by the fear of losing important data. The most valuable asset for many users is their phone book, containing the numbers of colleagues, relatives and friends. Fortunately, the ecosystem Android offers many ways to migrate data, making this process as simple and automated as possible.
Previously, migrating contacts required manual entry or complex manipulations with memory cards. Today data synchronization happens in the background or with a couple of taps on the screen. However, the variety of manufacturers and versions of the operating system sometimes introduces confusion into standard procedures.
In this article we will analyze in detail all the current methods for copying a phone book from an old device to a new one. We will consider both built-in system tools and specialized applications that guarantee the safety of your information in any gadget replacement scenario.
Synchronization through a Google account: the most reliable method
Using Google cloud storage is the “gold standard” for Android users. This method does not require the installation of additional software and ensures that your data will be safe even if the physical device is lost or damaged.
To get started, you need to make sure that contact synchronization is enabled on your old phone. Go to the settings, find the section Accounts and synchronization or simply Users and accounts. Select your profile Google and make sure that the switch opposite the "Contacts" item is in the active state.
After synchronization is enabled, the system will automatically upload all records to the corporation's servers. This process may take from a few seconds to a couple of minutes, depending on the size of your phone book and the speed of your Internet connection.
- 🔄 Open the system settings on your old smartphone.
- 🔐 Enter the Google account management section.
- ✅ Activate the contact synchronization slider.
- ☁️ Wait for a message about the successful update of data in the cloud.
On the new device, just log in to the same Google account. The system will automatically pull all saved numbers into the local address book. This solution is ideal for those who value process automation and do not want to waste time on manual file management.
Periodically visit contacts.google.com from your computer to check the relevance of your backup and, if necessary, merge duplicate entries.
Use built-in applications from manufacturers
Many large brands are developing their own utilities for seamless transition between devices of the same brand or even from different manufacturers. These applications often have advanced functionality, allowing you to transfer not only contacts, but also call history, messages and system settings.
For example, device owners Samsung can use an application Smart Switchthat creates a direct communication channel between phones via Wi-Fi Direct or cable. Similar solutions exist from Xiaomi (Mi Mover), Huawei (Phone Clone) and other vendors.
The process usually looks like this: you install the application on both devices, select the “Sender” role on the old phone and “Receiver” on the new one. After scanning the QR code or entering a special key, data transfer begins.
| Manufacturer | Application name | Connection type | What it carries |
|---|---|---|---|
| Samsung | Smart Switch | Wi-Fi / Cable | Contacts, photos, applications |
| Xiaomi | Mi Mover | Wi-Fi Direct | Contacts, SMS, settings |
| Huawei | Phone Clone | Wi-Fi Hotspot | Entire system, contacts |
| Device settings | Cable / Wi-Fi | Basic data, accounts |
The main advantage of such utilities is their deep integration with the operating system. They can correctly process specific fields of a contact card that may be lost during standard export to a file .vcf.
What to do if branded applications do not see each other?
Make sure that both phones are connected to the same Wi-Fi network or that the receiving device has an enabled hotspot. Sometimes rebooting both smartphones before starting the pairing procedure helps.
⚠️ Attention: When using proprietary utilities from different brands (for example, transferring from Samsung to Xiaomi), the functionality may be limited to only basic data, such as contacts and media files, without transferring system settings.
Export and import via VCF file format
A universal method that works on any smartphone, regardless of model and year of manufacture, is to create a backup file. The VCF (vCard) format is the industry standard for storing contact information and is supported by all email clients and address books.
To create such a copy, open the standard Contacts application on your old device. In the settings menu (often hidden behind three dots in the corner of the screen), look for Contact management or Import/export. Select the option to export to internal memory.
The system will create a file with the name type contacts.vcf or 00001.vcf. This file can be transferred to a new phone in any convenient way: via instant messenger, email, Bluetooth, or simply by copying it to a computer and then to a new device.
On the receiving smartphone, just open the received file. The system will automatically recognize the format and offer to import the found entries into the phone book or into the selected account. This is an excellent method for one-time transfer of a large amount of data without being connected to the Internet.
- 📂 Open the "Contacts" application on the source device.
- 💾 Select the "Export" function in the control menu.
- 📤 Send the created file to a new smartphone.
- 📥 Open the file on the new device and confirm the import.
Always check the result after completing the procedure.
The VCF file is the most universal transfer method, which guarantees compatibility even between devices of different operating systems, for example, when moving from iOS to Android.
Transfer data from a SIM card: the old proven method
Despite the development of cloud technologies, many users still store numbers on a SIM card. This method has its limitations, but can be a salvation in situations when the smartphone does not turn on or there is no access to the Internet.
The main disadvantage of storing contacts on a SIM card is the limitation on the length of the number and the lack of additional fields. Typically, only a name and one phone number can be stored on one memory cell, without an address, mail or notes.
To transfer, insert the SIM card from the old phone into the new one (or use a second SIM card if the device supports Dual SIM). Then go to the contacts application, select the menu and find the item Import from SIM card.
The system will prompt you to select a destination for the imported entries: the device’s phone book or a Google account. It is recommended to immediately save them to your account so that in the future you do not depend on the physical card of the telecom operator.
⚠️ Attention: When copying from a SIM card, long names may be cut off, and Cyrillic characters in some old card standards may not be displayed correctly.
This method is best suited as a temporary solution or for transferring the most important numbers when other methods are not available. For a complete database migration, it is considered obsolete due to the low quality of the stored information.

Third-party applications for data migration
If the built-in tools for some reason do not work or you need to transfer data between devices with very different versions of Android, applications from the store Google Playcome to the rescue. There are many free utilities that specialize in this task.
Popular solutions, such as Copy My Data, SHAREit or Send Anywhere, use Wi-Fi Direct technology to create a high-speed transmission channel. They do not require a connection to the same Wi-Fi router network; the devices connect directly to each other.
The interface of such apps is usually extremely simple: you select the type of data to transfer (in our case, Contacts), scan the code on the second device and start the process. The transmission speed is limited only by the capabilities of the wireless module of smartphones.
Using third-party software provides flexibility, but requires attention to permissions. When installing, be sure to check what rights the application requests so as not to provide access to personal information to third-party developers.
- 📲 Download the selected application on both smartphones.
- 🔗 Connect devices via Wi-Fi Direct or QR code.
- 📋 Select a category “Contacts” for transfer.
- 🚀 Start the process and wait for a notification of success.
This approach often helps when transferring data from older models, where modern synchronization protocols may not work correctly or be absent altogether.
Why is transfer via Wi-Fi Direct faster than Bluetooth?
Wi-Fi Direct technology provides significantly higher channel throughput, allowing you to transfer thousands of contacts in a matter of seconds, while Bluetooth can take several minutes.
Solving problems with duplicate and broken records
After transferring contacts, users often encounter the problem of duplicate records. This happens when the same number is stored in both the phone memory and in the Google account, or has been imported several times in different ways.
Modern versions of Android and the Google Contacts application have a built-in duplicate merging feature. It automatically finds entries with the same names or numbers and offers to combine them into one card, saving all available information.
To manually clear, go to the contacts application settings and select Contact management, then Merge duplicates. The system will show a list of suspicious pairs that you can confirm or reject at your discretion.
It is also worth paying attention to broken records that may contain unreadable characters or empty fields. Such artifacts often appear when transferring from older devices or through incompatible file formats.
⚠️ Attention: Before mass deleting or merging entries, be sure to create a backup copy of the current phone book in order to be able to roll back changes in case of an error.
Regular cleaning of the address book not only frees up space, but also speeds up the search for contacts, making using the smartphone more comfortable.
Automatic merging of duplicates in Google Contacts is based on machine learning algorithms, so sometimes it is worth checking the result manually so as not to lose unique notes.
Frequently asked questions (FAQ)
Will photos of contacts be transferred during synchronization?
Yes, if you If you use synchronization via a Google account or modern proprietary utilities (Smart Switch, Mi Mover), photos are linked to the contact and transferred with it. When exporting to a VCF file, photos can be saved if they are embedded in the file, but when transferred from a SIM card, the images are always lost.
What to do if contacts have been transferred, but are displayed in hieroglyphs?
The problem with encoding often occurs when importing from old files or from SIM cards. Try changing the file encoding when exporting (select UTF-8) or use converter applications. As a last resort, it’s easier to upload contacts to Google Sheets, correct the encoding there and upload them back.
Is it possible to transfer contacts if the screen of an old phone is broken?
If the sensor does not work, but there is an image, try connecting a USB mouse via an OTG cable for control. If the screen is completely black, but the phone turns on, the only chance is to remove the SIM card or try remote access through services like Find My Device, if they were configured earlier.
How many contacts can you save in a Google account?
Google Contacts limits are very high and almost unattainable for the average user. You can store tens of thousands of contacts without any problems. Limitations may only arise with bulk imports at one time (usually up to 5000 records per operation), which must be broken into parts.
How to delete contacts from your old phone after transfer?
After successfully testing the contacts on your new device, you can reset your old phone to factory settings. This will automatically delete all data. If you want to keep your phone, go to your account settings and turn off synchronization, then delete contacts locally so that they are not deleted from the cloud.
