Changing a smartphone is always an exciting process, but transferring the phone book often becomes the main stumbling block for users. Losing important numbers, duplicate entries, or mixing contacts from different SIM cards can create real chaos in your address book. Fortunately, the ecosystem Android offers a variety of built-in and third-party tools that allow you to migrate data in minutes without losing quality.
In this article we will look in detail at all available methods: from cloud synchronization via Google Account to local transfer via Bluetooth or NFC. You will learn how to avoid common mistakes, save call history and correctly configure the display of names on a new device. Whether you're upgrading from a budget device to a flagship or simply upgrading to a different model, these instructions will help keep your connections intact.
Preparatory stage: check and backup
Before you begin any active actions, you need to make sure that both devices are ready to go. Charge your old and new phone at least to 50%so that the process is not interrupted at the most crucial moment due to low battery. Also check the availability of free space in the memory of the new gadget, although contacts take up a minimum of space, system backup processes may require a buffer zone.
Open the application on your old device and view the list. Remove obvious duplicates or empty entries so as not to transfer “garbage” to the new device. If you have multiple accounts, determine where your primary numbers are stored: in your phone's memory, on your SIM card, or in the cloud. This is critical to choosing the correct export method.

Make a manual backup through your system settings. Go to Settings → System → Backup and make sure that the switch opposite the “Contacts” item is active. Click the “Start copying” button to save the current state of the database to the cloud before starting manipulations. This is your insurance in case of unexpected failures.
☑️ Preparing for transfer
⚠️ Attention: If you use a corporate account or specific instant messengers to store numbers, make sure you have rights to export data. In some cases, administrators limit the ability to upload an address book.
Synchronization via Google Account: the most reliable method
Using cloud services Google is the “gold standard” for Android users. This method requires no cables and works automatically as long as both devices are signed in to the same account. All data is stored on the company’s servers, which eliminates the risk of losing information if the physical media breaks down.
On your old phone, go to the section Settings → Accounts and select your Google profile. Click on “Account Synchronization” and make sure that the slider next to the section Contact is turned on. If the switch was turned off, turn it on and wait a few minutes until the download icon disappears, confirming the completion of data transfer to the server.
Now take a new smartphone. During initial setup, enter the same Google username and password that you used on your old device. The system will automatically offer to restore data from a backup copy. If your phone is already set up, just add your account to the settings menu and force synchronization. In a couple of minutes, the entire phone book will appear in the application.
Use the web version of contacts.google.com for a quick check: if the numbers are visible in the browser on your computer, it means they have been successfully uploaded to the cloud and will soon appear on your phone.
It is important to understand the difference between storage on SIM and in the cloud. Contacts saved in Google Contactshave extended fields for notes, photos and additional numbers, which the SIM card does not support. Therefore, it is recommended to always keep your main database in the cloud, and not on a physical chip.
Synchronization through Google is the only method that provides automatic real-time contact updates on all your devices at the same time.
Using the Quick Start feature data-i="68">Modern versions of Android are equipped with a built-in migration wizard that allows you to transfer contacts from an old phone to a new Android directly, without the Internet. This method is ideal when you don't have access to Wi-Fi or want to transfer data from an old device that has already been reset to factory settings but not yet activated.

This method is ideal when you don't have access to Wi-Fi or want to transfer data from an old device that has already been factory reset but not yet activated.
Turn on your new smartphone and begin the setup process. When the system prompts you to connect a cable or use a wireless connection, follow the onscreen instructions. Often you need to connect both phones with a cable USB-C to USB-C or use an adapter. If a cable is not available, select wireless mode and scan the QR code displayed on the new device with the camera of the old one.
After the connection is established, the system will prompt you to select the type of data to transfer. In the list, be sure to tick the item Contact, as well as, if desired, the history of calls and messages. The process can take from 5 to 30 minutes depending on the amount of information. Do not disconnect or lock your phone screens until the operation is completed.
| Transfer method | Speed | Internet required | Difficulty |
|---|---|---|---|
| Google Account | High | Yes | Low |
| USB cable (Quick Start) | Very high | No | Medium |
| VCF file (Bluetooth) | Low | No | Medium |
| SIM card | Medium | No | Low |
What to do if the transfer is stuck?
If the process is stuck at 90%, don't panic. This often happens when transferring large media files. Try interrupting the process, rebooting both phones and starting the transfer again, selecting only contacts and messages, turning off photos and videos.
Export and import via VCF file
The method using a file format VCF (vCard) is a universal solution when cloud services are not available or you want to transfer contacts to a specific person. A VCF file is a text document containing structured information about contacts, which is understood by almost all email clients and instant messengers.
Open the contacts application on your old device. From the menu (usually three dots or bars), select “Manage contacts” or “Import/export”. Click Export to .vcf file. The system will prompt you to select a save location: internal memory or memory card SD. Remember the path to the file, it is usually called 00001.vcf or contacts.vcf.
Now you need to deliver this file to the new phone. The easiest way is to send it via instant messenger (Telegram, WhatsApp) or email to yourself. Once you have the file on your new device, simply click on it. The system will automatically prompt you to open it through the Contacts application and ask where to save the imported entries. Select your main Google account for automatic synchronization in the future.
- 📂 A VCF file can contain hundreds of contacts in one document, which is convenient for mass transfer.
- 📧 You can even send such a file from iPhone to Android and vice versa, the format is cross-platform.
- 🔒 The file is stored locally, which increases data confidentiality compared to the cloud.
If you are using a memory card, just move microSD from the old phone to the new one. Go to the file manager of the new device, find the file and tap on it. This is one of the fastest methods for users who prefer a physical storage medium.
Transfer via SIM card: the classic method
Despite the development of technology, transfer via SIM card remains popular because of its simplicity and independence from software. This method is especially relevant for older phone models or when you need to quickly transfer a basic list of numbers without unnecessary settings.
On your old phone, go to the contacts settings and select the function Copy contacts to SIM card. Please note that the SIM card has limited memory (usually up to 250 entries) and only supports a name and one phone number. Long names will be truncated, and additional numbers (work, home) may be lost or merged.
After copying, turn off the old phone, remove the SIM card and insert it into the new device. Turn on the device, go to the contacts application, open the menu and select Import from SIM card. The system will prompt you to select a destination: save contacts to your phone memory or to your Google account so as not to lose them the next time you change SIM cards.
⚠️ Attention: When importing from a SIM card, duplicates are often created if some of the numbers have already been synchronized via the cloud. Once the import is complete, be sure to use the Merge Duplicates option in Contacts Settings.
This method is not suitable for transferring contact photos, email addresses, or detailed information. Use it only as a temporary solution or to create an emergency copy of your main numbers.
Why are names truncated?
The data storage standard on SIM cards is outdated and is limited to 14-16 characters per name. Anything longer is simply cut off when writing to the chip, so long names like “Alexander Sergeevich” will turn into “Alexander Serg.”
Solving problems with duplicates and display
After you managed to transfer contacts from your old phone to a new Android, you may encounter the problem of clutter in your address book. Duplicates occur frequently, especially if you used several transfer methods at the same time or previously synchronized data from different sources (for example, social networks and SIM cards). Modern Android skins, such as clean or clean, have built-in cleaning tools. Go to the Contacts app settings and look for Manage Contacts or Merge Duplicates. The system will automatically scan the database, find records with the same names or numbers and offer to combine them into one card.
Modern Android skins such as MIUI, One UI or clean Pixel UI, have built-in cleaning tools. Go to the Contacts app settings and look for Manage Contacts or Merge Duplicates. The system will automatically scan the database, find records with the same names or numbers and offer to combine them into one card.
Also check your display settings. Sometimes it seems that the contacts are missing, but in fact the filter is turned on. In the contact list, click on the menu and select Contacts to display. Make sure that the “All contacts” checkbox is checked or the required accounts are selected. If you select "Phone only", you will not see numbers saved in Google.
- 🧹 Clean duplicates regularly to speed up your phone book search.
- 👁️ Check your display filters if, after transferring, the list seems to be empty.
- 📸 Add photos manually after merging, since when merging records, the photo may be reset.
If the built-in tools do not cope, you can use specialized applications from Google Play, for example, “Contacts Optimizer”. They allow you to flexibly configure merge rules and delete contacts without numbers or names.
The correct organization of contacts after the transfer is more important than the transfer process itself: a clean database saves time when searching for numbers in the future.
Frequently asked questions (FAQ)

Check your internet connection and make sure contact synchronization is enabled in your account settings. Try deleting your account from your phone and adding it again. Also clear the cache of the Contacts application via Settings → Applications → Contacts → Storage → Clear cache.
Is it possible to transfer contacts if the old phone is broken and does not turn on?
If the phone does not turn on, but The SIM card is intact, move it to the new device and import the numbers. If the contacts were stored in the phone memory or the cloud, log into your Google account from a computer or a new phone - the data should be updated automatically if synchronization was previously enabled.
How to transfer contacts from iPhone to Android?
The easiest way is to install the application Google Drive or "Transfer to Android" on iPhone, back up your contacts to your Google account, and then log into that account on your new Android smartphone.
Will contacts disappear from the old phone after the transfer?
No, when using synchronization methods, VCF or Quick Start, the data is copied rather than moved. The old phone will save all records. Deletion occurs only when transferring from a SIM card, if you select the “Move” option instead of “Copy”, but modern systems copy data by default.
