How to transfer contacts from SIM-card to Xiaomi Poco X3: all ways

Why SIM Contacts Are Important to Keep on Your Smartphone

A SIM card is not only a tool for calling, but also a store of your contacts, which can be lost when you change operator, damage your card or accidentally delete. Xiaomi Poco X3, like other Android smartphones, makes it easy to transfer this data to the device’s memory, but not all users know how to do it correctly. Unlike older button phones, where contacts were automatically saved to SIM, modern smartphones by default write them to Google account or internal memory.

The main problem is that SIM-Nano-SIM cards (like in Poco) X3) They are not physically designed to rewrite contacts frequently – their memory is limited (usually they are not physically capable of being rewritten). 250-500 It doesn't support fields like email or addresses, and it solves this problem by adding editing, backing up and syncing between devices. Also, when you reset or buy a new smartphone, you won’t lose important numbers if they’re stored in the cloud or on your device.

In this article, we’ll look at all the current ways to migrate contacts from SIM to Poco X3, from standard MIUI features to third-party applications, and give you tips on backup and troubleshoot possible errors. If you’ve never done this procedure, don’t worry: each method is illustrated in detail and adapted to the Xiaomi 2026 interface.

Method 1: Import contacts through standard MIUI settings

The easiest and safest method is to use the built-in MIUI tools, which require no additional applications and works even without an Internet connection.

1. Open the Contacts app (an icon with a person’s silhouette on the home screen or in the app menu).
2. Slip on the three horizontal lines (menu) in the upper left corner and select Contact Management.
3. Scroll down and click Import/Export Contacts → Import with SIM-map.
4. Choose. SIM-The card you want to copy your contacts with (if there are two of them).
5. Tick the necessary contacts or click Select all, then tap Import.
6. Specify the location of the save: Device (internal memory) or Google (cloud), and we recommend choosing both options for reliability.

It takes a few seconds to process, depending on the number of contacts you have, check if the numbers appear on your contact list, and if some of the records are not imported (for example, because of format incompatibility), try alternative methods in the following sections.

⚠️ Note: If after importing some contacts are displayed without names (numbers only), this means that the data on the SIM This can be fixed manually or by using applications such as Copy My Data (see Method 4).

Method 2: Export contacts to a VCF file and import to Poco X3

The.vcf (vCard) format is the universal standard for storing contacts that all modern smartphones support, and the advantage of this method is that you get backup contacts as a file that you can save to your computer or the cloud. Here's how to do it:

1. On an old phone (or via Poco) X3, if the contacts are already SIM) Export contacts to the file: 📱 Android: Contacts → Settings → Export (select the choice) SIM source). 🍎 iPhone: Use iCloud or Contacts app to export to.vcf.
2. Move the received file (for example, contacts.vcf) to Poco X3 through: 📎 Bluetooth or Wi-Fi Direct. 💾 USB-cable (connect your phone to your PC as a storage device). ☁️ The cloud (Google Drive, Mi Cloud).

Method 3: Synchronize your contacts with your Google account

If you use a Google account on Poco X3, this method will not only allow you to transfer contacts to the SIM, but also automatically sync them between all your devices.

1. Open Settings → Accounts and Sync → Google.
2. Sign in to your account (if not previously logged in) or select an existing one.
3. Activate the Contacts switch (and other data if necessary).
4. Return to the Contacts app, click on the three dots (menu) → Settings → Import/Export.
5. Select Import with SIM-Maps and Google as a place to save.

Once imported, the contacts will appear in your Google account and will be available at contacts.google.com. The main advantage of this method is automatic backup: even if you lose your phone, the contacts will remain in the cloud.

💡

If your SIM contacts are duplicated with those already in Google, combine them before importing: open contacts.google.com → Other → Find and combine duplicates.

Note that if you have previously synced contacts with another account (e.g. Mi Account), there may be a data conflict, in which case we recommend exporting all contacts to.vcf (Method 2) and then importing them to the desired account.

Method 4: Using Third-Party Applications

If the standard methods do not work (for example, due to damage) SIM And if you want to see them, or format incompatibility, you can use third-party apps to help you with additional functions like cleaning duplicates, retrieving remote contacts, and moving data across platforms.-3 test-driven:

• 📱 Copy My Data (free, no ads) – transfers contacts, photos and calendars between devices over Wi-Fi. Supports Android, iOS and even BlackBerry.
• 🔄 Contacts Backup & Restore – creates backup copies of contacts in.vcf and.xml formats, allows you to restore them selectively.
• ☁️ My Contacts Backup – sends contacts to email as a.vcf attachment, convenient for transfer to another phone.

Example of transfer using Copy My Data:

1. Install the app on both devices (old and Poco X3) from the Play Market.
2. On your old phone, select Send Data → Contacts → SIM.
3. On Poco X3, select Receive Data and connect to the same Wi-Fi.
4. Confirm the data transfer – the contacts will be copied to the phone’s memory.

⚠️ Note: When using third-party apps, turn off battery optimization for them in Xiaomi settings (Settings) → Annexes → Permits → Auto-start, otherwise the transmission may be interrupted.

Method 5: Manual contact entry (for a small number of records)

If you have fewer than 20 contacts on your SIM, the most reliable (albeit time-consuming) way is to type them manually, which ensures that there are no formatting errors and allows you to edit the data immediately.

1. Open the Contacts app and press + (add a new contact).
2. Enter your name and number, then click Save. Select the location of the save: Device or Google.
3. To speed up, use voice input: tap the microphone icon in the keyboard and dictate the data (for example: “Ivan Ivanov, phone 89123456789”).
4. To avoid duplicates, check existing contacts through an in-app search before adding.

This method is also useful if you want to structure contacts — for example, add photos, email or link numbers to social media accounts. MIUI has a contact merge feature: open post → click Edit → Link and select a duplicate to merge.
