Buying a new smartphone is always an exciting event, but the process of migrating personal data can cause certain difficulties. The most critical element for most users is the phone book, the loss of which is tantamount to breaking ties with business partners and loved ones. Fortunately, the ecosystem Android offers many built-in and third-party tools for seamless information transfer.
In this article we will examine in detail all the current methods of number transfer, from cloud synchronization to classic methods via a SIM card. You'll learn how to avoid duplicate entries and save additional fields such as email addresses and subscriber photos. The correct choice of method depends on the size of your database and the technical compatibility of the devices.
Before taking active steps, you need to make sure that both devices are charged and in working condition. Modern versions of the operating system have greatly simplified this process, making it intuitive even for beginners. Let's look at step-by-step algorithms for each available option.
Synchronization via Google account: the most reliable method
Using cloud storage Google Contacts is the most preferred method for owners of Android smartphones. This method ensures that your data will be saved even if the physical device is lost or damaged. The principle of operation is based on linking records to your unique identifier in the system.
First, you need to check the settings on your old phone. Go to the Settingssection, find the item Accounts or Users and accounts. Select your Gmail email address and make sure the switch next to Contact is in the active position. If synchronization was disabled, turn it on and wait for the update process to complete.
After the data has been sent to the cloud, we proceed to setting up the new gadget. When you first start Android the system will prompt you to enter your Google account login and password. It is enough to enter the same data that was used on the old device, and the phone book will download automatically in the background.
If you have several Google accounts, make sure that on the new phone, the one where your database is stored is selected as the main one for synchronizing contacts.
It is important to note that this method transfers not only phone numbers, but also all related information: addresses, birthdays, notes and linked photos. This makes the method of synchronization via Google Cloud the most complete solution for migrating data between devices from different manufacturers.
Synchronization via a Google account allows you to restore contacts on any device, just enter your login and password.
Transfer via SIM card: the classic universal method
The method of copying data to a SIM card is considered outdated in terms of technology, but it remains the only universal solution that does not require the Internet or complex software setup. This option is ideal if you need to quickly transfer numbers between phones of different operating systems, for example, with iPhone to Android or vice versa.
The main disadvantage of this approach is the serious limitation on the amount of information stored. A standard SIM card can hold a limited number of entries, usually between 250 and 500, depending on the operator and chip type. In addition, when exporting, the contact name is often cut off if it is too long, and additional fields are completely lost.
The transfer process is as follows: on the old device, open the application Contact, go to the settings menu and select Import/Export. Click on the option Export to SIM card. After the operation is completed, move the chip into a new smartphone and perform the reverse procedure - Import from SIM card.
Why may contact names be displayed incorrectly?
SIM cards use an old encoding standard that often does not fully support Cyrillic or special characters, which is why names can turn into a series of question marks or hieroglyphs.
⚠️ Attention: Before removing the SIM card, make sure that the phone is turned off to avoid damage to the chip contacts or a software failure in the communication module.
If your new phone has a SIM card slot combined with a memory card tray, be extremely careful when removing it. Use the special clip included in the package to avoid damaging the tray mechanism. After importing, be sure to check several random entries for the correct display of names.
Using the Bluetooth function for wireless transfer
Technology Bluetooth allows you to transfer contacts directly between devices without using the Internet and intermediate media. This method is convenient when you need to transfer not the entire book at once, but only a few specific numbers or a group of selected contacts to a nearby interlocutor.
To carry out the transfer, open the phone book application on the sending device. Highlight the desired entries with a long press (you can select several contacts at the same time). In the menu that appears, select the option Share or Send contact, and then specify the transfer method via Bluetooth.
On the receiving device, you must first enable visibility for other devices in the Bluetooth settings. After sending format files .vcf a notification about the incoming file will appear on the new phone. Agree to receive and save, after which the system will automatically offer to import data into the address book.
It is worth considering that the transmission speed via Bluetooth is relatively low, so sending the entire phone book containing thousands of entries can take considerable time. In such cases, it is more advisable to split the process into several stages or use other, faster synchronization methods.
Specialized applications and tools from manufacturers
Large smartphone manufacturers are developing their own utilities to facilitate data migration when changing devices. These apps often have advanced functionality compared to standard system tools, allowing you to transfer not only contacts, but also call history, messages and settings.
For example, equipment owners Samsung can use an application Smart Switchthat creates a direct connection between the old and new phone via Wi-Fi Direct or cable. Users Xiaomi have a similar tool Mi Mover, and the company Huawei offers a solution Phone Clone. These applications automatically detect the type of data being transferred.
Third-party developers also offer powerful solutions such as Copy My Data or Send Anywhere. Such applications work on the principle of generating a QR code or digital key: you scan the code on a new phone, and the devices are connected into a single network for exchanging files.
| Application | Manufacturer | Connection type | Features |
|---|---|---|---|
| Smart Switch | Samsung | Wi-Fi / Cable | Transferring system settings |
| Phone Clone | Huawei/Honor | Wi-Fi Direct | High transfer speed |
| Copy My Data | MediaTech | Wi-Fi network | Cross-platform (iOS/Android) |
| SHAREit | Smart Media4u | Hotspot | Transferring any files |
When using third-party software, it is important to monitor the permissions that the app requests. Make sure that the application has access only to the necessary sections of memory and contacts to prevent leakage of personal information to the network.
☑️ Preparing to use carrier applications
Manual export and import via VCF file
Format VCF (vCard) is a universal standard for storing contact information. It is a plain text file that can be opened and read by almost any device, including computers and tablets. This method gives the user complete control over the backup process.
To create a backup, go to the contacts application, select the menu and press Settings. Find the item Export and indicate the location to save the file. The system will create a file with the extension .vcfcontaining all selected records. This file can be saved to internal memory or to a microSD card.
Next, the file must be physically moved to a new device. This can be done via a computer by connecting phones with USB cables, or by sending the file to yourself via email, instant messenger or cloud storage. On a new phone, just click on the file, and the system will offer to import the data it contains.
⚠️ Attention: The VCF file can take up a significant amount of memory with a very large number of contacts with photos, so make sure that there is enough free space on the receiving device.
The advantage of this method is the ability to edit the file on your computer before importing. You can open it in a text editor, remove duplicate entries, or correct misspelled names using the search and replace feature. This is especially true when clearing the database of outdated numbers.
Solving problems with duplicates and merging records
A common problem after transferring contacts is the appearance of duplicates, when the same person appears in the list several times. This happens if data was imported from different sources at the same time, for example, from a SIM card and from a Google account. Modern smartphones have built-in tools to solve this problem.
The application Google Contacts has an automatic merge function. If records with the same names or numbers are detected, the system will offer to combine them into one card. For manual control, go to the application menu and select Fix and manage, then Merge duplicates.
If automatic merging did not work correctly, you can perform the procedure manually. Open the contact card, click on the menu (three dots) and select the option Merge with another. The system will show a list of similar contacts from which you can select the one you need to merge. All data from both cards will be saved in the final record.
What to do if contacts are missing after the update?
Most often they are not deleted, but simply hidden from display. Go to the contact display settings and make sure that the checkbox next to the desired account or storage source is checked.
Regularly cleaning the phone book from duplicates not only improves the visual perception of the list, but also speeds up the operation of the device when searching for the desired subscriber. It is recommended to carry out such a check immediately after completing the process of transferring data to a new gadget.
The function of merging duplicates in Google Contacts works automatically, but requires manual verification for complex cases with different names of one person.
⚠️ Attention: The menu interface and item names may vary slightly depending on the version of Android and the manufacturer's shell (MIUI, OneUI, ColorOS). If you do not find the specified option, use the search in the settings.
Frequently asked questions (FAQ)
How to transfer contacts if the old phone is broken and will not turn on?
If the device does not turn on, but the SIM card is working, remove it and insert it into the new phone to import numbers. If the contacts were saved in the phone's memory and not on the SIM card, try connecting the broken device to the computer via USB in debugging mode (if the screen responds) or remove the memory card if the data was stored there. In case of complete failure, data can only be restored from the latest backup in the Google cloud.
Is it safe to transfer contacts through third-party applications?
Using popular applications from well-known developers (Samsung, Xiaomi, Google) is absolutely safe. When downloading third-party software from the Play Market, pay attention to the rating and number of downloads. Avoid apps that require excessive permissions not related to data transfer, and do not transfer confidential information through unverified services.
Is it possible to transfer contacts from iPhone to Android?
Yes, this is possible in several ways. The easiest one is to install the application Copy My Data to both devices and transfer data via Wi-Fi. You can also export contacts from iCloud to a VCF file on your computer, and then upload this file to your Google account, which is synchronized with your new Android smartphone.
Why, after transfer, contacts are displayed without names, only numbers?
This often happens when transferring via a SIM card due to limitations in the data storage format on the chip. The problem may also occur if the contacts were saved in a format that is incompatible with the new version of Android. The solution is to repeat the transfer through the Google cloud service or VCF file, which support full name encoding.
How to back up your contacts before selling your phone?
The best way is to make sure that synchronization with your Google account is enabled and complete. Additionally, you can export all contacts to a VCF file and save it to your computer or send it to yourself by email.
