Owning a new smartphone like the POCO X3 often starts with basic but critical tasks, including keeping a phone book in the first place. Many users still store numbers directly on a carrier chip, a relic of the past that carries the risk of data loss when a SIM card breaks or is replaced. Transferring contacts from a SIM card to a Xiaomi POCO X3 phone is not just a matter of convenience, but a necessity to ensure the security of your personal data.
Modern Android devices offer flexible synchronization mechanisms, but the process of importing from SIM may not be obvious to beginners due to the features of the MIUI shell. In this article, we will discuss in detail all available ways to copy numbers, consider the nuances of working with cloud services and local storage, and answer frequent questions that arise during data migration.
The security of your contacts is a priority, so we will focus on choosing the right storage location: contacts saved in the Google or Mi Account cloud are automatically restored even after a complete flashing of the device. Local copying without backup can lead to irretrievable data loss in the event of a physical breakage of the smartphone.
Preparation of the device and SIM card for migration
Before proceeding with the copying procedure, you need to make sure that your device POCO X3 It recognizes the SIM card correctly, inserts the chip into the slot, wait for the network signal to appear, and make sure that the numbers are displayed in the call list, even if they are not already stored in the phone's memory. Sometimes the system may request unlocking. SIM-code to be entered before any manipulations are initiated.
It is important to check for free space in the memory of the smartphone, although this is rarely a problem for text records of the phone book. However, if you plan to transfer records with extended data (photos, additional numbers), free space may be required. Also make sure that the battery level is at least 20-30% so that the process does not stop suddenly.
- 📱 Make sure the SIM card is active and displays the operator’s name in the status bar.
- ☁️ Check if you have an internet connection if you plan to sync your data to the cloud immediately.
- 🔋 Charge the battery of the Xiaomi device POCO X3 avoiding unexpected shutdown.
If you’re using a new SIM card and the old one is in another device, pre-export contacts on the old phone to.vcf format or copy them to the SIM card there.Storage standards on different SIM cards may differ, and older chips sometimes have limits on the length of the contact name or the number of characters in the room.
Import contacts through the standard “Contacts” application
The most direct and obvious way to migrate data is to use the built-in functionality of the system. In the MIUI shell that is installed on the POCO X3, the phone book application has advanced functionality hidden in the settings menu. Open the Contacts app (usually an orange icon with a human silhouette) and find three dots or menu buttons in the upper or lower corner of the screen.
In the menu that opens, select "Import contacts" and the system will suggest selecting a data source. SIM-Once you have selected the source, the system will suggest you specify the destination, the place where the numbers will be stored, and here lies the important point: do not choose the phone unless you plan to back up manually.
⚠️ Note: When you select the option of saving "Phone" (local storage), your contacts will be linked exclusively to this physical device. POCO X3 Recovering them without a backup will be impossible.
Once you have selected a save location (your Google account is recommended), the system will request confirmation. Click OK or Import. The process takes from a few seconds to a couple of minutes, depending on the number of records, and when you complete, you will see a successful import notification, and all the numbers will appear in common with reference to the selected account.
Working with Google Account and Synchronizing
Google's ecosystem is native to Android, and using it to store contacts is the most reliable method. When you import data from a SIM card directly into your Google account on Xiaomi's POCO X3, it automatically syncs with the corporation's servers, which means that you can access your phone book from any device, just enter your username and password.
Contact management can be done using not only the phone interface, but also the web version of contacts.google.com. This is especially useful if you need to edit duplicates, merge records or correct company names. Any changes made through your browser will instantly affect your POCO X3 with the Internet.
- 🔄 Automatic synchronization occurs in the background without user involvement.
- 🛡️ Data protected by two-factor authentication of Google account.
- 📝 Ability to edit and remove duplicates through the web interface.
If you have a sync error when importing, check your account settings in Settings → Accounts and Sync. Make sure the slider opposite Contacts is activated. Sometimes forced sync is required: click on three points in your account profile and select Sync.
💡
Use the “Combine Duplicates” feature in the Contacts app to clear the list of repetitive entries that often occur when multiple imports from different sources.
Use of the Mi Cloud cloud service
Owners of smartphones Xiaomi and POCO They have access to the proprietary cloud storage, Mi Cloud, which is deeply integrated into the system, and allows you to back up not only contacts, but also messages, notes and system settings. SIM-Mi Cloud cards are similar to Google but require a registered Mi Account.
The main advantage of this method for brand users is the ability to fully restore the state of the phone when you switch to a new Xiaomi model. When you first set up a new device, just log into your Mi Account, and the phone book will be loaded automatically, which creates a closed and convenient ecosystem.
But remember the limits of free storage: The basic plan provides 5GB, which is more than enough for thousands of contacts, but if you plan to store photos and videos there, the space may run out. Unlike Google, which compresses photos in original quality for free (under certain conditions), Mi Cloud strictly monitors the volume.
| Parameter | Google Contacts | Mi Cloud | Local (Phone) |
|---|---|---|---|
| Synchronization | Automatic. | Automatic. | Absent. |
| Access to PC | Yes (web interface) | Yes (i.mi.com) | No (need cable/file) |
| Brand dependency | No (works everywhere) | Better on Xiaomi/POCO | Only on this device. |
| Risk of loss | Minimum | Minimum | High-pitched |
| Storage volume | 15 GB (total) | 5GB (baseline) | Depends on the phone's memory. |
💡
The optimal strategy is dual redundancy: basic sync through Google and periodic full copy through Mi Cloud to restore system settings.
Export and import via VCF file
Sometimes there are situations where direct synchronization is not possible or you need to transfer contacts to a device without the Internet. In such cases, the.vcf (vCard) format comes to the rescue. USB-cable.
To create such a file on POCO X3, first import from the SIM card to the phone's memory (temporary). Then, in the Contacts menu, select Export Contacts. The system will suggest saving the file to internal memory or to an SD memory card. Once you create the contacts.vcf file, you can copy it to your computer or send it to your mail.
To import data from a file, just look it up in the MIUI file manager and click on it. The system will ask where to save contacts, a method that is convenient for transferring data between different brands, such as from an iPhone to Android or from an old button phone, if it managed to unload the file.
⚠️ Attention: Format files VCF Do not send it to public chat rooms or unknown servers, as the contents of the file are easy to read and use by third parties.

Solving problems when copying
The transfer process doesn't always go smoothly: Xiaomi users POCO X3 You may have a memory error. SIM-The card is crowded when you try to copy, although in fact the problem is often in the storage format.SIM cards have strict restrictions: usually no more than a single card. 250 The length of the name and the length of the name (about) 10-15 symbols) and numbers.
If the import is interrupted or some numbers are “cut off”, this means that the data on the SIM card does not meet the GSM standards that the phone requires, in which case it is recommended to first copy the contacts to the old phone, clear the SIM card, and then rewrite the numbers back, but with full names, if you allow, or immediately to the cloud.
- ❌ The “Insufficient Memory” error is often solved by cleaning the Contacts app cache».
- 📞 Some special characters in names may not be supported by the SIM card.
- 🔒 Lockdown SIM-The code may interrupt the import process before it is entered.
Also worth mentioning is the problem of encoding: when you transfer from very old phones, names can be displayed by "krakozers", whether you change the encoding when you import it through third-party converter apps or manually fix the most important contacts after transfer.
