Moving to a new smartphone or the need to use one SIM card in different devices often requires transferring the phone book. Device owners Samsung may be faced with a situation where all records are stored in the device’s memory or in the cloud Google, and the standard import procedure is not obvious. This is especially true when changing an operator or temporarily installing a card in a push-button phone.
The process of copying numbers to SIM card in the ecosystem Android has its own characteristics related to the limitations of the chip's memory capacity. Unlike internal memory, a SIM card cannot store additional data such as photos, email addresses or notes. Therefore, before starting the procedure, it is important to understand that you are transferring only names and main phone numbers.
In this article we will analyze in detail the algorithm of actions for smartphones Samsung Galaxy with a shell One UI. You'll learn how to safely migrate data, what risks exist, and how to avoid losing valuable information. Follow the instructions to ensure your contacts are always at hand, regardless of device.
Prepare data before transfer
Before you begin the active phase of moving records, it is critical to create a backup copy of them. Any manipulation of the contact database carries the risk of accidentally deleting or corrupting files. If something goes wrong during the process, you should be able to quickly restore the list of numbers.
The most reliable way is to export contacts to an internal drive or send the file by email. To do this, open the application Contact, go to the control menu and select the file creation function .vcf. This format is universal and supported by all modern operating systems.
It is also recommended to check the quality of entries in the phone book. Make sure that important numbers are not duplicated and are written in international format. This will make them easier to use after transferring to another medium.
⚠️ Attention: If you have more than 500 contacts, the process may take several minutes. Do not interrupt the application or remove the SIM card until the operation is completed.
Take a screenshot of the most important number (for example, a doctor or close relative) before starting work. This will help you quickly restore it manually in case of a failure.
Step-by-step guide for the One UI interface
Smartphones Samsung work under a proprietary shell One UI, which is slightly different from the clean one Android. The path to the necessary settings here is intuitive, but requires care when choosing the source and destination of data.
Open the application Contact. At the bottom of the screen or in the top corner (depending on the firmware version), find the menu icon - usually three horizontal stripes. Click on them to expand the list of available actions.
In the list that appears, select the item Manage contacts. All the tools for working with the phone book are concentrated here: import, export, deleting duplicates and merging entries. Our goal is the copy function.
Click on the option Move contacts. The system will prompt you to select a data source. If your numbers are saved in the phone's memory, select Phone. If they are synchronized with an account Google, select the appropriate account.
☑️ Check before starting
After selecting the source, the system will ask you to mark the entries for transfer. You can select specific numbers manually or press the button at the top of the screen to move the entire phone book at once. All next step. Now you need to specify your destination. In the list of available options, find your at the top of the screen to move the entire phone book at once.
Selecting destination and limiting SIM memory
When you have marked the entries you want, click the button Ready or an arrow to move to the next step. Now you need to specify your destination. Find yours in the list of available options. SIM card. It can be signed as SIM 1 or SIM 2, depending on which slot it is installed in.
Here the user often encounters the first limitation. SIM card memory is strictly limited by cellular communication standards. It usually holds from 250 to 500 entries, but modern cards from some operators may have even less capacity.
If you try to move more contacts than the card allows, the system will issue a warning. In this case, you will have to select the most important numbers manually. Mass transfer of thousands of records to one chip is physically impossible.
| Media type | Maximum records | Photo storage | Email storage |
|---|---|---|---|
| Phone memory | Unlimited | Yes | Yes |
| Google account | Unlimited | Yes | Yes |
| SIM card | 250-500 pcs. | No | No |
| SD memory card | Depends on volume | Yes | Yes |
Why are names truncated?
The GSM standard used by SIM cards only supports Latin and a limited number of Cyrillic characters. Long names are often truncated to 10-15 characters or replaced with question marks.
After confirming your selection, the copying process will begin. The progress bar will show the progress status. Upon completion, you will see a notification about the successful transfer.
Features of storing names on a SIM card
It is important to understand the technical specifics of storing data on the operator chip. SIM card uses an outdated file system that is not designed for storing multimedia or long text strings.
When transferring contacts from Samsung to a SIM card, you will inevitably lose some information. Profile photos, addresses, social media links and second phone numbers will be removed. There will only be one name and one main number left.
In addition, problems with encoding may arise. Cyrillic names sometimes display incorrectly on other devices, especially if you insert the card into a phone from a different manufacturer or an older model. In such cases, names can turn into a set of incomprehensible characters.
The SIM card is only suitable for basic number storage. For a full phone book with photos and details, use your Google account.
If saving a complete contact profile is critical for you, consider alternative backup options, for example, exporting to a file or synchronizing with cloud storage.
Alternative backup methods
Transferring to physical media is not the only and often not the best way to save contacts. Modern smartphones Samsung offer more flexible and reliable tools for data management.
Synchronization with an account Google occurs automatically and unnoticed by the user. Just add mail in the phone settings and turn on the corresponding switch in the Accounts and archivingsection. Your contacts will be accessible from any device where you enter this username and password.
- 📱 Smart Switch: A proprietary utility from Samsung allows you to instantly transfer all data, including contacts with photos, to a new phone via cable or Wi-Fi.
- 💾 Export to file: File creation
.vcfallows you to save a complete copy of the phone book and send it to yourself by email or save it in a cloud drive. - ☁️ Samsung Cloud: Owners of brand devices can use a proprietary cloud to backup settings and data, although the functionality is gradually transferred to partners services.
These methods have no memory limitations and preserve the entire record structure. Use transfer to SIM only in extreme cases when other methods are not available.
Frequent problems and their solutions
Sometimes users are faced with the fact that the move button is inactive or the process ends with an error. Most often this is due to the fact that the contacts are already on the SIM card or the wrong source is selected.
Check the display settings. Go to the contacts menu and make sure that displaying entries from SIM cardsis enabled. If the checkbox is only on the phone, you will not see empty cells on the SIM card and will not be able to write anything there.
Another common problem is card protection. Some operators install PIN code on the SIM card every time you turn on the phone. If you do not enter it correctly when loading the system, access to writing to the chip will be blocked.
⚠️ Attention: The menu interface may differ slightly on series Galaxy A, M and flagship Smodels. If you do not find the "Contact Management" item, look for it in the general phone settings through the search.
If a failure occurs, try restarting the device and repeating the procedure. If the error persists, remove the SIM card, wipe the contacts with a soft cloth and insert it back until it clicks.
Is it possible to transfer contacts from photos to a SIM card?
No, the technical specification of SIM cards does not support storing graphic files. When transferring, photos will be automatically deleted, leaving only text information.
What to do if contact names have become hieroglyphs?
This is an encoding problem. Try changing the phone system language to English, transferring, and then returning to Russian. However, there is no guaranteed solution, since the SIM standard is outdated.
How many contacts can a modern SIM card hold?
The standard capacity is from 250 to 500 entries. The exact number depends on the telecom operator and the type of chip (3G or 4G/5G), but it will not be able to exceed 500 numbers.
Will contacts disappear from the phone after transferring to SIM?
When using the "Move" function, the originals are deleted from the phone's memory. If you want to leave copies in both places, use the "Copy" function or first export to a file.
How to restore contacts from SIM back to the phone?
Go to the contact management menu, select "Import contacts", specify the source SIM card, and the destination - phone memory or Google account.
