If you try to copy more contacts than there is available space, the process will be interrupted or some of the data will be lost.
⚠️ Attention: Before bulk import, it is recommended to create a backup copy of the current phone book if there are already important numbers in the phone memory, to avoid accidental overwriting or data conflicts.
Check the availability of free space in the internal memory of your smartphone. Although contacts take up little space, the system needs resource to perform write operations. Go to Settings → Memory and make sure that at least a few tens of megabytes of free space are available.

Transfer through the system settings menu
If the phone book application does not have the required function or it does not work correctly, you can use the system settings. This method is often more stable, since it directly addresses account and data storage management.
Go to the main menu Settings of your smartphone. Scroll down the list to the Contact or Users and accountssection. In some versions Android this item may be hidden inside the section System or Advanced settings.

|---|---|---|
| Copy My Data | Fast transfer via Wi-Fi or from SIM | Android / iOS |
| SA Contacts | Management, merging and import | Android |
| Move to Android | Migration from iPhone or SIM | Android |
| Contacts Optimizer | Clearing and transferring data | Android |
After finishing the third-party application, it is recommended to check the result in the standard phone book. Make sure all numbers are displayed correctly and have names associated with them.
Why can third-party apps be dangerous?
Some little-known utilities may request redundant permissions, such as access to SMS or location, that are not needed to copy contacts. Always check the application rating and reviews before installing.
Synchronization with Google cloud storage
The most advanced method is not just copying it to the phone’s memory, but uploading it to the cloud. This ensures that your data will not be lost even if the device is physically destroyed. To do this, use the service Google Contacts.
Open the application Contact and go to the synchronization settings. Make sure that the switch opposite your Google account is active. If you have just imported numbers from a SIM card into the phone's memory, they will automatically be sent to the cloud during the next synchronization.
You can also force synchronization. Go to Settings → Accounts → Google. Select the desired account and click Synchronize. Make sure that the checkbox opposite the item Contact is checked.
You can check the result through a browser on your computer by going to the website contacts.google.com. If you see your numbers there, it means the process was successful and the data is securely protected.
Synchronization with Google is the “gold standard” for data security. It eliminates the need to manually transfer contacts every time you change your phone.
Problem solving: duplicates and import errors
During the transfer process, the problem of duplicating records often arises. This happens if the same number was saved both on the SIM card and in the phone memory earlier. The system can create two different cards for one person.
To solve this problem, use the merge function. In the application Contact click on the menu and select Manage contacts, then Merge duplicates. The system will automatically find similar entries and offer to combine them into one.
If the import does not start or gives an error, try removing the SIM card and inserting it again. Make sure the clean SIM card contacts are not damaged. Sometimes rebooting the smartphone before trying again helps.
⚠️ Attention: If the names on the SIM card are written in an encoding that is not supported by the phone (for example, specific characters), they may appear as hieroglyphs. In this case, you will have to edit the names manually after import.
It is also worth remembering that the storage format on the SIM card is very primitive. Long names may be truncated, and numbers written in international format may lose the country code. Check the number format after transfer.
Use the Reverse Lookup feature in Google Contacts to automatically add photos and clarify names for imported numbers if they were saved as numbers only.
