Changing a mobile device often becomes a catalyst for bringing order to the user’s digital life. One of the first tasks that the owner of a new gadget based on Androidfaces is migrating the phone book. Many users, out of habit or for reasons of compatibility, store numbers directly on SIM card, which in the era of smartphones is not the most reliable and functional solution.
Storing records on a telecom operator's chip imposes significant limitations: the name length is often cut to 10-12 characters, there is no possibility of linking photos, email addresses and additional numbers. In addition, the SIM card's memory capacity is extremely small and usually does not exceed 250 entries. Therefore, transferring data to the phone’s internal storage or cloud account Google is a necessary step to fully use the capabilities of a modern mobile OS.
The import process does not require special skills or a connection to a computer. The entire procedure is performed directly in the smartphone interface in a couple of minutes. However, the menu location and item names may differ slightly depending on the version of the operating system and the manufacturer's proprietary shell, be it Samsung One UI, Xiaomi MIUI or pure Android.
Preparing the device and checking storage capacity
Before you start copying data, you need to make sure that the SIM card is correctly detected by the system. Insert the chip into the appropriate slot and wait for the network icons to appear in the status bar. If your device supports two SIM cards, pay attention to which one you plan to import from, as systems often ask you to select a source.
Make sure that space has been created or already exists on the device to store contacts. In modern smartphones, this can be the local memory of the phone or a synchronized account Google. Using a cloud profile is preferable, as this guarantees data safety even if the device is physically broken or lost.
⚠️ Attention: If more than 250 numbers are recorded on the SIM card, the import process may fail or copy only part of the records due to hardware limitations of the chip. In this case, it is recommended to transfer data in parts or use backup through operator services.
Check the availability of free space in the internal memory of the smartphone. Although one contact takes up a negligible amount of space, transferring thousands of records and associated metadata (photos, notes) can require several megabytes of free space. Clearing the cache before the procedure will not be superfluous.
☑️ Ready for transfer
Standard import method through the Contacts application
The most universal way to move records is built directly into the standard Contacts application, which is present on any device running Android. The interface may vary, but the logic of action remains the same for most OS versions. You will need to find the subscriber list management menu.
Open the application and go to the settings section, which is often hidden under the three dots or gear icon in the top corner of the screen. In this section you need to find the item responsible for data management, for example Import/Export contacts or Contact Management. This is where the migration tools are concentrated.
After selecting the import function, the system will prompt you to specify the data source. Select option SIM card. If your phone has two slots, check which card (SIM 1 or SIM 2) you need to read information from. Next, you will need to indicate the destination: phone, Google account or another account.
The system will show a list of found entries and offer to select all or tick specific numbers. Confirm the action by clicking the “Import” or “Copy” button. The process will take from a few seconds to a minute depending on the number of subscribers. Once complete, you will see a notification that the transfer was successful.
After importing, be sure to go to several contact cards and check if the names are displayed correctly. Often, long names from the SIM card are cut off and will have to be edited manually.
Features of transfer in shells from different manufacturers
Smartphone manufacturers often modify the standard interface Android, adding their own functions and changing the menu structure. This can be confusing for a user accustomed to a “clean” interface. Let's look at the nuances for popular brands so that you can quickly find the right option.
In devices Samsung the path usually looks like this: open "Contacts", click on the menu (three horizontal lines), select Settings, then Contact management and finally Import contacts. Here the system allows you to flexibly choose which fields to transfer and where to save them.
On smartphones Xiaomi (MIUI or HyperOS shell) the logic is similar, but the terminology may differ. Go to the application, click on the three dots in the upper corner, select Settings -> Import and export contacts. Please note that in some firmware versions this function may be hidden in the general system settings in the “Applications” section.
| Brand / Shell | Path to the import menu | Features |
|---|---|---|
| Samsung (One UI) | Contacts -> Settings -> Contact management | Support for selecting multiple sources at the same time |
| Xiaomi (MIUI) | Contacts -> Settings -> Import/Export | Frequent requests for permissions to access memory |
| Google Pixel | Settings -> Import from SIM card | Minimalistic interface, minimum steps |
| Huawei (EMUI) | Contacts -> Management -> Import/Export | Ability to merge duplicates in the process |
If you can’t To find the item you need, use the search in your phone settings. Enter the word “Import” or “Contacts” into the search bar, and the system itself will highlight the required menu section. This significantly speeds up navigation in complex interfaces.
Alternative method via VCF file
Sometimes direct import through the settings menu is not possible due to software glitches or format incompatibility. In such cases, the universal format VCF (vCard) comes to the rescue. This method involves creating an intermediate file that contains all the contact information in text form.
First you need to export the contacts from the SIM card to a file. In the import/export menu, select the option Export to storage or Save to .vcf file. Specify the source as SIM card. The system will create a file that will be saved in the internal memory of the device, usually in the root or in a folder Contacts.
After creating the file, perform the reverse operation - import from the file. Select the created document .vcf as the source and specify the target destination folder (Google account or phone memory). The good thing about this method is that the file can be previously copied to your computer for editing or backup storage.
⚠️ Warning: When exporting to a VCF file, make sure you save it to your internal memory and not to your SD card, if you have one. In some cases, the system does not see external drives during subsequent import for security reasons.
VCF files are also convenient because they can be sent to yourself by email or messenger, and then opened on any other device to instantly add the entire phone book. This is an ideal way to quickly synchronize between several gadgets.
Synchronization with Google account and cloud
The most modern and reliable way to store contacts is to link them to an account Google. When importing from a SIM card, immediately select your Gmail account as the destination. This will ensure automatic synchronization of data with the company's servers.
Once the contacts are saved in the cloud, you can manage them via the web interface contacts.google.com from any computer. There are advanced tools available for merging duplicates, recovering deleted entries from the last 30 days, and bulk editing names and numbers.
If you change your phone, you won't need to repeat the SIM import procedure. Simply enter your Google account login and password on your new device, and your entire phone book will download automatically in the background. This saves time and eliminates the human factor.
What to do if synchronization is frozen?
If contacts do not appear in the cloud, go to Settings -> Accounts -> Google, select your mailbox and click “Sync contacts”. You can also try clearing the cache of the Contacts and Google Play Services applications.
It is important to regularly check the synchronization status. Make sure that the “Contacts” item is checked in your account settings. Disabling this option will result in new entries being saved only locally and not being protected from loss.
Eliminating common problems and duplicates
During the process of transferring data, users often encounter the appearance of duplicates - situations where the same person is recorded twice: once from the SIM, another time from the phone memory. Modern versions of Android have built-in algorithms to solve this problem.
To merge entries, open the Contacts application, go to settings and find the item Merge duplicates or Manage contacts. The system will offer to automatically find similar names and numbers, offering to merge them into one card. This allows you to clear the list of visual debris.
Another common problem is name encoding. If after import you see strange symbols or question marks instead of Russian letters, this indicates an encoding conflict between the old-style SIM card and the new file system. In this case, only manual renaming or re-import through a VCF file with the correct UTF-8 encoding will help.
⚠️ Attention: Mobile operating system interfaces are updated regularly. If the described menu paths do not match your screen, check the help in the settings of your specific device or contact the manufacturer's official website.
If none of the software methods worked, try removing the SIM card and inserting it into another, simpler phone (push-button), export contacts from there to a memory card in VCF format, and then insert this memory card into an Android smartphone and import data from it.
Using a Google account to store contacts is the only way to guarantee their safety in the event of a breakdown, theft, or complete reset of the smartphone to factory settings.
Frequently asked questions (FAQ)
Can I transfer contacts if the phone screen is broken and does not work?
If the sensor does not respond, but there is an image, try connecting a USB mouse via an OTG adapter. This will allow you to manage the interface and go into the import settings. If the screen is black but the phone works, try connecting to your computer via USB debugging (if it was previously enabled) or using Google Voice Assistant to make calls, although a full import is difficult to do.
How many contacts can fit on a regular SIM card?
The standard capacity of most modern SIM cards is between 250 and 500 records. However, old Mini-SIM cards could only hold 100-150 numbers. When you try to record more data, old records may be overwritten or new ones simply will not be saved.
Will the contacts from the SIM card disappear after they are copied to the phone?
No, during the standard import procedure the data is copied, not moved. The original recordings will remain on the SIM card. If you want to free up space on the chip, after successfully importing and checking the data, you need to manually delete contacts from the SIM through the same management menu.
Why are long names cut off during import?
This is a technical limitation of the data storage format on the SIM card. The name field there is limited to 14 bytes (for Latin) or less for Cyrillic. When importing to a phone, these restrictions are removed, but if the name has already been saved cropped on a SIM card, it will not be possible to restore its full version automatically - you will have to add it manually.
Is it possible to transfer contacts from iPhone to Android via SIM card?
Technically this is possible, but not recommended. iPhone allows you to export contacts to SIM, but most of the information (photos, addresses, second numbers) is lost. It is better to use the “Move to iOS” application (it does not work in the opposite direction) or synchronize iPhone contacts with a Google Account through the iCloud settings, and then add this account to Android.
