Buying a new smartphone is always a joyful event, but it is often overshadowed by the need to recover important data. The most critical asset for most users is their phone book, the loss of which can be a nightmare. Fortunately, the ecosystem Android offers several reliable and proven ways to transfer records from an old device to a new one.
In this article we will look in detail at how to synchronize contacts to a new Android phone using cloud services, local files and a direct connection. You'll learn how to avoid duplicate entries and why storing data on a SIM card is considered an outdated method today. Getting this procedure right will save you hours of manually entering numbers.
Preparing your old device for migration
Before you begin the migration process, you need to make sure that all the records on your old device are in order and available for export. Often, users do not even suspect where exactly their numbers are stored: in the phone’s memory, on a SIM card or already in the cloud. Checking the current status is the first and most important step.
Go to the Contacts application and open the display settings. Make sure that the mode to show all available sources is selected. If you see numbers stored only in the device memory or on the SIM, they must first be combined or exported. For reliable synchronization, it is best to use Google account as a central storage.
Open your phone settings and find the “Accounts” section. Select your Google profile and click Sync. Make sure the slider next to Contacts is active. This action will forcefully upload all local records to the Google cloud, making them available to any device where you sign in.
⚠️ Attention: If on your old phone contacts are saved in the manufacturer's proprietary format (for example, only in Samsung or Xiaomi memory without linking to Google), automatic synchronization may not work. In this case, you must manually export them to a .vcf file.
Before starting the transfer, clear the phone book of duplicates. Many modern smartphones have a built-in “Merge duplicates” function in the contacts settings menu.
Synchronization via Google Account
The simplest and most effective method is to use the Google cloud infrastructure. When you turn on your new smartphone for the first time, the system will prompt you to sign in to your existing account. As soon as you enter your username and password, all data will be automatically retrieved, including call history, calendar and, of course, contacts.
The process occurs in the background and does not require your constant participation. However, the speed at which numbers appear in the phone book of a new device depends on the speed of the Internet connection and the number of entries. This usually takes from a few seconds to a couple of minutes.
If contacts do not appear immediately, check the synchronization settings on the new device. Go to Settings → Accounts → Google and make sure that the checkbox next to “Contacts” is checked. You can also click on the three dots in the corner of the screen and select “Sync now” to force an update.
- 🔄 Automation: All new contacts created on any device will instantly appear on all other gadgets.
- 🛡️ Security: Data is stored on secure Google servers and will not be lost even if the phone breaks or is lost.
- 🌐 Availability: You can view and edit numbers even from your computer through the service Google Contacts.
Transfer via vCard file (VCF)
Sometimes using the cloud is impossible due to lack of Internet or the desire to maintain complete confidentiality of data without uploading to third-party servers. In such cases, the ideal solution is to use a file format vCard (.vcf extension). This universal format is supported by all versions of Android and most other operating systems.
To create a backup, open the Contacts app on your old phone. From the control menu (usually three dots or a line), select Import/Export or Manage Contacts. Click Export to File or Export to Storage. The system will create a single file containing all your entries.
The resulting file must be transferred to the new phone. This can be done via Bluetooth, instant messengers (Telegram, WhatsApp), email, or simply by copying the file to your computer and then to a new smartphone. On a new device, just open this file, and the system will offer to import the contents into the phone book.
Settings → Contacts → Import/export → Import from .vcf fileThis method is especially useful for mass transfer of thousands of entries, when cloud synchronization may be unstable due to traffic limits or session time. The vCard file ensures that you transfer exactly the set of data you selected.
What to do if the file does not open?
Make sure the file has a .vcf or .vcard extension. If the file is damaged or has a non-standard extension, try renaming it manually or using a third-party import application, such as Copy My Data.
Using a SIM card for migration
Although this method is considered obsolete, it is still relevant for users of push-button phones or in situations where the smartphone is completely inoperable, but the SIM card is intact. The main limitation of a SIM card is the amount of memory. It usually holds from 250 to 500 entries.
In addition, only the name and phone number are stored on the SIM card. All additional information such as email addresses, photographs, titles and addresses will be permanently lost during this transfer. Therefore, it is recommended to use this method only as a temporary solution or for the most important numbers.
To copy the data, insert the SIM card into the old phone (if it is not already there) and select the “Copy from phone to SIM card” option in the contacts menu. After that, move the card to the new smartphone and perform the reverse operation: “Copy from SIM card to phone” or “Import from SIM card.”
| Characteristics | Google Account | VCF file | SIM card |
|---|---|---|---|
| Memory capacity | Unlimited | Depends on storage | 250-500 records |
| Saving photos | Yes | Yes | No |
| Internet required | Yes | No | No |
| Complexity | Low | Medium | Low |
⚠️ Attention: When importing from a SIM card, contact names may be cut off or displayed incorrectly if an encoding other than the GSM standard was used. Always check the import result.
Restoring from a local backup
Many smartphone manufacturers, such as Xiaomi, Samsung and Huawei, have their own cloud services and backup tools. If you have previously used these functions, you can restore contacts through the manufacturer's proprietary application.
For example, Samsung owners can use the service Samsung Cloud or application Smart Switch. Xiaomi users rely on Mi Cloud. The process is similar to working with Google: you need to log in to your manufacturer account on the new device and select “Restore data.”
Local backups can also be stored in the phone’s internal memory in hidden folders. If you regularly made backups through the standard Backup and Restore application, the data file may be located in the directory /backup/. It can be transferred to a new phone and deployed through the same settings menu.
☑️ Check before restoration
Solving problems with duplicates
A common problem after synchronizing contacts to a new Android phone is the appearance of duplicates. This happens when the same number is saved in both the Google account, the phone memory, and the SIM card. The system perceives them as different entries, creating chaos in the phone book.
Modern versions of Android have built-in algorithms to combat this phenomenon. Open the Contacts app, go to Settings and look for Manage Contacts or Merge Duplicates. The system will offer to automatically find and merge duplicate entries.
If the automatic tool does not work, you can use the web version of Google Contacts. In the interface on the computer, there is a menu on the left where the “Merge and Fix” option is located. This tool works much more accurately and allows you to manually control the process of merging cards.
It is also worth paying attention to the display settings. Log in Settings → Display contacts and select “Only with phone” or “Only with Google account” to temporarily hide unnecessary entries and understand the source of duplication.
Regularly cleaning duplicates through the Google Contacts web interface is the most effective way to keep your phone book in perfect condition condition.
FAQ: Frequently asked questions
Why are contacts not synchronized after logging into your account?
Most often the problem lies in disabled synchronization in the account settings or lack of Internet. Check to see if the contact sync slider is active. Also try deleting the account from the phone settings and adding it again.
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, you can transfer only those numbers that are stored on it. If the data was stored in the phone's memory or in the Google cloud, it is impossible to retrieve it from a non-working device without repair, but cloud data is available from any other gadget.
Is it safe to store contacts on Google servers?
Yes, Google uses modern encryption protocols to protect user data. The risk of leakage is minimal compared to the risk of losing a physical SIM card or breaking the phone without a backup.
How to transfer contacts from iPhone to Android?
The easiest way is to log into your iCloud account through a browser on your computer, export contacts to vCard format, and then download this file to your Android smartphone. You can also use the “Move to iOS” application in the opposite direction or third-party utilities.
What should I do if, after importing, names are displayed as numbers?
This means that the matching of numbers and names did not occur correctly. Check if you have imported the entire file. Try clearing the phone book and repeating the import, making sure that the file is not damaged.
