Device owners Samsung often face the need to transfer an address book when changing a telecom operator or after purchasing a new smartphone. Storing numbers on SIM card is considered an outdated method, since the chip has extremely limited memory and does not support storing additional fields, such as email or photo of the subscriber.
Modern smartphones based on Android, including flagship series Galaxy S and budget lines Galaxy Aoffer advanced synchronization tools. Moving records to internal memory or a cloud account Google guarantees their safety even if the physical media is lost or the gadget is broken.
The import procedure on devices Samsung is simplified as much as possible thanks to the proprietary shell One UI. You don't need to install third-party software or get root access. It is enough to use the standard “Contacts” application, which is pre-installed on every device of this brand.
Why you should refuse to store numbers on a SIM card
Many users habitually store phone numbers directly on the carrier chip, without thinking about the technical limitations of this method. The main disadvantage is the memory limit: a standard SIM card can hold only 250 to 500 records, which is critically small for an active user.
In addition, the data storage format on the SIM card is archaic. When you transfer such a contact, you often lose the ability to add a home address, job title, or multiple email options to the number. It is also impossible to link an individual ringtone or photo if the record is physically located on the operator's chip.
⚠️ Attention: When you remove the SIM card, all contacts stored on it become inaccessible to the smartphone. If you lose your plastic card, it will be almost impossible to restore the numbers without contacting a communication store.
Transferring data to the device memory or cloud service Google Contacts opens access to the full functionality of managing the address book. You can easily sort subscribers into groups, search for them by name and instantly synchronize your database between your tablet, phone and computer.
Preparing the device for the import procedure
Before you start the transfer contacts, you need to make sure that the SIM card is correctly detected by the system. Insert the chip into the slot of your Samsung Galaxy and wait for the network icon to appear in the top notification bar. Without active registration of the card on the network, the import function may be inactive.
It is recommended to check in advance the availability of free space in the internal memory of the smartphone. Although text data takes up a negligible amount of space, the system must have the resource to create new records in the database. Clear the cache if the storage is full.
An important step is to create a backup copy of your current address book if you already have important numbers on your phone. This will prevent accidental duplication of entries or their loss in the event of a software failure during the copy operation.
☑️ Preparing for the transfer
Step-by-step guide through the Contacts application
The most reliable way to move numbers is to use the built-in application from Samsung. Open the application menu and find the icon with a silhouette of a person, labeled as Contact. Launch the app to access your address book management.
In the main application interface, find the menu icon, which usually looks like three horizontal stripes (“hamburger”), located on the left side of the screen. Click on it to expand the list of available actions and settings.
In the drop-down list, select the item Contact management. This is the section where all the tools for working with the database are concentrated: from importing and exporting to merging duplicates and deleting records.
On the next screen, find the “Import and export contacts” section and click on the button Import contacts. The system will prompt you to select a data source. In this case, you need to specify the option SIM card. If you have a device with two SIM cards, select the one on which the numbers are stored.
After selecting the source, the system will ask you to specify the destination. It is recommended to select Google Account for automatic synchronization or Phoneif you want to store data locally. Click the “Import” button and confirm the action.
What to do if the import button is inactive?
If the import option is not pressed, check whether the SIM card is PIN-locked. Also make sure that the chip actually has stored numbers by going to the settings of the chip itself through the network menu.
Import through Android system settings
If for some reason the standard application is not available or does not work correctly, you can use deep system settings Android. This method is universal and suitable for any firmware version One UI.
Go to the main Settings of your smartphone by clicking on the gear icon in the notification shade or in the application menu. Scroll down the list to the section responsible for accounts and data management.
Find the item Contact or “Manage contacts” depending on the version of the operating system. In some builds, this item may be located inside the “General Settings” or “Applications” section.
Select the import option and follow the prompts of the transfer wizard. The interface may differ slightly on models Galaxy A54 or Galaxy S23, but the logic of action remains the same for the entire ecosystem Android.
| Parameter | SIM card | Phone memory | Google Account |
|---|---|---|---|
| Record limit | 250-500 numbers | Depends on memory | Unlimited |
| Additional. fields (Email, photo) | No | Yes | Yes |
| Risk of data loss | High | Medium | Zero |
| Synchronization | Absent | Only on the device | Automatic |
Solving common problems during transfer
Sometimes users are faced with a situation where, after import, contacts are displayed incorrectly or some numbers are lost. This is often due to character encoding or name length limitations on the old SIM card.
If you notice that some names are cut off or hieroglyphs are displayed instead of letters, try changing the encoding in the display settings. However, most often the problem is solved by manually editing duplicates after completing the procedure.
⚠️ Attention: Do not interrupt the import process by closing the application or turning off the smartphone screen. This may damage your contacts database and require a full reset.
If you receive an "Out of Memory" error, clear space on your internal storage. Delete unnecessary photos, videos or the cache of heavy applications to free up space for recording new data.
For advanced users, it is possible to use commands via USB debugging, but for the usual task of transferring numbers this is overkill and can be dangerous without the proper skills.
After importing, be sure to go to your Google account synchronization settings and click "Sync now" to create a cloud copy of your new address book.
Data synchronization and backup
After successfully transferring numbers to internal memory, it is extremely important to set up their backup. This will protect your address book from loss in the event of theft of the device or its physical destruction.
Go to Settings → Accounts and archiving → Account management. Select your account Google and make sure that the switch next to “Contacts” is active.
Branded The utility Samsung Cloud also allows you to create local backups that can be restored when moving to a new phone of the same brand. This is especially convenient when migrating within a brand ecosystem.
Checking your sync status regularly ensures that any changes you make to your phone book are instantly reflected in the cloud. You can manage your contacts even through the web interface from your computer.
Storing contacts in your Google account is the only way to guarantee their eternal safety and accessibility from any device in the world.
