Storing phone numbers directly on the SIM card is an outdated but still common method that often creates problems when changing devices. Smartphone owners Samsung Galaxy regularly face the need to transfer this database to internal memory or a cloud account in order to gain access to expanded information fields and high-quality photos of subscribers. Modern operating systems provide several effective tools for performing this task without losing valuable data. The import process does not require special technical skills, however, the menu interface may vary slightly depending on the shell version and the model of your gadget. Correct execution of the procedure ensures that all your connections will be preserved even in the event of physical damage or loss of the SIM card. Below we will analyze in detail standard copying methods, and also consider the nuances of working with various storage formats.

The import process does not require special technical skills, however, the menu interface may differ slightly depending on the shell version One UI and the model of your gadget. Correct execution of the procedure ensures that all your connections will be preserved even in the event of physical damage or loss of the SIM card. Below we will analyze in detail standard copying methods, and also consider the nuances of working with various storage formats.
Preparing the device and checking the visibility of contacts
Before you begin active transfer actions, you need to make sure that the smartphone correctly recognizes the installed SIM card and sees the numbers recorded on it. Sometimes the problem lies not in the lack of an import function, but in the contact list display settings. Go to the application Contact, which is standard for the ecosystem Samsung, and open the settings menu through three horizontal bars or a dot in the corner of the screen.
In the contact list management section, select the option Displayed contacts. Here the system will prompt you to specify the source, numbers from which should be visible in the general phone book. Make sure there is a checkmark next to your SIM card (it may appear as SIM 1 or by your carrier name). If this item is disabled, you simply will not see old entries, and the copying procedure will become impossible.
It is also worth checking whether contacts are hidden due to filtering by groups or tags. Full visibility of all records is a key step before data migration begins. After confirming that the old numbers are displayed in the list, you can proceed directly to the export function.
⚠️ Attention: If after enabling the display of SIM contacts the list is still empty, try rebooting the phone in safe mode or removing and reinserting the SIM card while the power is off.
Classic import method through the app Contacts
The most reliable and versatile way to transfer data is built right into the standard call management application. This method works on all current models, from budget series Galaxy A to flagship series Galaxy S. Open the application Contact and find the menu button, which is usually located in the upper or lower right corner of the interface.
In the drop-down list, you must select an item Manage contacts. This section contains all the tools for working with the database: removing duplicates, merging records and, in fact, transferring. Find the line Move contacts or Import contacts —the name may vary depending on the localization of the firmware.
System will ask you to select a data source. Please specify SIM card. Next, you will be asked to select your destination. For maximum security and convenience, it is recommended to choose Phone (internal memory) or, even better, your account Google. Selecting internal memory will make the numbers available only on this device, while the Google account will ensure their synchronization.
☑️ Algorithm of actions when importing
After selecting the destination storage, the system will show a list of all found numbers. You can tick specific entries or use the Select all function for bulk transfer. Press the button Done or Import and wait for the process to complete, the indicator of which will appear at the top of the screen.
Before bulk import create a backup copy of your current phone book through the app settings to have a fallback point in case of failure.
Transferring data through Samsung system settings
An alternative way to the same function is through the general settings of the smartphone. This method is convenient if the Contacts application icon has been removed from the desktop or hidden. Go to the main menu Settings of your device Samsung and scroll down the list to the section Contact.
Inside this menu you will see an item Move contacts. Clicking on it will launch the same system module as in the previous method. You will again need to select the source (SIM) and destination. The advantage of this path is that it often works more stable on devices with highly customized launchers.
If you have two SIM cards installed in your phone, the system will prompt you to select a specific slot for reading data. Carefully check which card you plan to copy numbers from so as not to get confused in the sources. The process of writing to the internal memory is almost instantaneous, even for large lists of several hundred entries.
Using Smart Switch to migrate data
For users who have just bought a new smartphone Samsung and want to transfer contacts from an old device (not necessarily Samsung), a proprietary utility is ideal Smart Switch. This application is pre-installed on all new gadgets of the brand and allows you to transfer data in various ways: via cable, via Wi-Fi or saving a backup copy on an external drive.
Run the application Smart Switch on both devices. On the receiving phone, select the “Data Recipient” role, and on the old one, “Sender”. After connecting the devices using the proposed method (for example, a USB-C to USB-C cable), you will be asked to select the types of information to be transferred.
In the list of data, be sure to check the box Contact. The utility will automatically determine where they are stored - on the SIM or in the internal memory of the old phone, and offer the optimal transfer path. This method is good because it not only copies numbers, but also saves the folder structure, favorite contacts and linked images.
| Transfer method | Working speed | Required equipment | Risk of data loss |
|---|---|---|---|
| Import via menu | Instantly | Phone only | Minimal |
| Smart Switch (Cable) | High | USB cable | Missing |
| Smart Switch (Wi-Fi) | Average | Stable network | Low |
| Manual entry | Very low | Two phones | High (human factor) |
Upon completion of the transfer, the application will generate a report on the number of successfully transferred records. If errors occur during the process with specific contacts, Smart Switch usually indicates them separately, allowing you to try again for problematic elements.
What to do if Smart Switch does not see the old phone?
Make sure that Wi-Fi and Bluetooth are turned on on both devices. For a wired connection, a special adapter may be required if the connectors on the phones are different (for example, Micro-USB on the old one and Type-C on the new one).
Synchronization with a Google account is the best option
Storing contacts exclusively on the SIM card or in the internal memory of the phone carries certain risks. If the device is lost or the SIM card is damaged, the entire phone book may be lost forever. The most progressive solution is synchronization with cloud storage Google Contacts.
To activate this function, go to Settings → Accounts and archiving → Account management. Select your Google profile and make sure that the switch next to Contact is active. After synchronization is enabled, all new numbers will be automatically saved in the cloud.
To transfer old entries from SIM, first follow the import procedure to the phone's internal memory (as described in the section above), and then allow synchronization. The system will automatically upload local contacts to Google servers. After this, you will be able to manage your phone book from any device by simply logging into your account.
⚠️ Attention: During synchronization, duplicates may occur if the same number is stored both on the SIM and in the phone memory under different names. Use the “Merge Duplicates” feature in the Contacts app.
Using the cloud also makes it easy to recover deleted contacts. The Google service stores a history of changes for 30 days, which makes it possible to roll back the phone book to the state of yesterday or a week ago if you accidentally deleted an important group of subscribers.
Synchronization with Google is the only way to guarantee the safety of contacts in the event of a complete loss or theft of a smartphone.
Possible errors and ways to eliminate them
During the copying process, users may encounter various system error messages. One of the most common problems is the “Not enough space” message or recording failure. This can happen if the phone's internal memory is full, although the contacts take up a negligible amount of space. In this case, clear the application cache Contact through the app settings menu.
Another common situation is that contacts were imported, but are displayed with hieroglyphs or question marks instead of letters. This is an encoding issue that is rare on modern Androids, but possible when migrating from very old feature phones. The solution is to edit such contacts manually or use third-party applications to convert the databases.
If the import button is greyed out, check whether the Calls Only mode or a limited profile is enabled. Also make sure that the SIM card is not protected by a PIN code, which blocks access to reading the data until it is entered. Enter the PIN code when loading the phone to unlock access to the SIM card file system.
Why are contacts duplicated after import?
This often happens because the number is saved in different formats (for example, +7 and 8). The system considers them different records. Use the clear duplicates feature.
⚠️ Attention: The menu interface and item names may vary slightly depending on the Android version and regional firmware of your Samsung device. If you do not find an exact match, look for synonyms (for example, “Management” instead of “Settings”).
Results and recommendations for organizing your phone book
Transferring contacts from a SIM card to a smartphone Samsung is a simple but a critical procedure for the modern user. It provides access to the full functionality of the phone book, including adding email addresses, notes and high-resolution photos for each subscriber.
We strongly advise you not to stop at simply copying to the internal memory, but to immediately set up synchronization with a cloud service. This will save you from having to repeat the import procedure every time you change devices and will provide reliable protection against accidental data loss.
Regularly check the relevance of your records and delete outdated numbers. A clean and well-structured phone book saves time and makes communication more comfortable. Use grouping by categories (Family, Work, Friends) to quickly access the people you need.
Is it possible to copy contacts back from the phone to the SIM card?
Yes, it is possible. In the same menu Manage contacts select the option Export contacts or Move contacts, specify the source Phone (or account), and the destination - SIM card. However, remember that the SIM card has limited memory and long names or special characters.
What to do if after copying the names disappear, only numbers remain?
Most likely, there was an encoding failure or the contacts were written in the wrong format. Try deleting problematic entries and entering them manually. Also check if contacts with names are hidden in the display settings (filter “Numbers only”). In rare cases, resetting the Contacts application helps.
How many contacts fit on one SIM card?
The capacity of a SIM card depends on its age and type. Old cards contain about 250 numbers, modern ones - up to 500 or more. However, the name length on the SIM card is limited to 14-20 characters, so long names will be cut off when exporting.
How to merge duplicate contacts on Samsung?
Open the application Contact, press the menu (three bars) and select Manage contacts. Click on item Merge contacts. The system will offer to merge duplicates automatically or allow you to manually select pairs of records for merging.
