How to transfer contacts with SIM to Xiaomi: the complete guide

Moving to a new smartphone is always accompanied by a desire to customize the device faster, but users often face the problem of transferring the old phone book. Owners of Xiaomi, Redmi and Poco devices may find that numbers stored on the old SIM card do not appear in the call list automatically, due to security limitations and the architecture of the Android operating system, which requires explicit permission of the user to import data from a physical medium.

The information transfer procedure is a basic feature, but in the MIUI shell or the new HyperOS, menu item names may differ from standard Android. Incorrectly performing actions sometimes leads to duplication of records or their complete loss. In this article, we will discuss in detail how to correctly copy numbers, avoid typical errors and adjust automatic synchronization for future devices.

It’s important to understand that a SIM is an outdated storage medium with extremely limited memory. Modern smartphones allow you to store thousands of contacts with photos, additional numbers and addresses, which a standard SIM can not offer. So transferring data to internal memory or to the Google cloud is not just a convenience, but a necessity for the full use of the capabilities of a smartphone.

Preparation of SIM-card and compatibility check

Before you start taking action, you need to make sure that the physical media is properly installed and properly installed in the tray. If you just inserted a SIM card from an old button phone or other smartphone, wait about a minute before full registration on the network. Lack of signal or constant attempts to search the network can indicate a loose fit of contacts or contamination of the chip.

Make sure that the SIM card itself actually has stored records. On older devices, users often saved numbers in their phone's memory, believing they were on a SIM card. To check, you can insert the card into any other device and see the contact list in the settings. SIM-If the list is empty, there is nothing to import, and you should look for backups in the memory of an old gadget or in your account.

⚠️ Warning: Don't try to retrieve the SIM card tray while the phone is on, unless absolutely necessary.While modern smartphones support hot replacement, frequent retraction can lead to contact oxidation or mechanical damage to the tray, which is especially critical for moisture-protected models.

The MIUI shell has strict rules for accessing contacts. When you first start the Contacts or Phone application, the system will ask for permission to read and write. If you accidentally click Denial, the import function will not be available, in which case you will manually go to the application settings and restore access rights, otherwise all further actions will be meaningless.

Standard method of import through the Contacts app

The simplest and most reliable method of data transfer is built into the regular call management app. The interface may vary slightly depending on the Android version and regional firmware, but the logic remains the same. You need to open an application that usually has a green icon with a handset or a human silhouette.

When you open the app, find the settings menu. Most versions of Xiaomi have it hidden under three dots in the corner of the screen or marked with a gear, and that's where the data management tools are. Select "Import contacts." The system will prompt you to select a source, and this list should display an option «SIM-map «SIM 1 / SIM 2" if you have a two-sim device.

Once you have selected a source, the system will suggest you specify your destination. It is critical to choose a Google account or phone memory, but not the SIM card itself (so as not to create a copy). Select your Google account so that the numbers are automatically saved to the cloud, ensuring that when you lose your phone or buy a new Poco or Redmi model, all the numbers will be restored instantly.

Start the copying process. The speed depends on the number of records, but it usually takes a few seconds. When you complete the operation, you will see a notification of a successful import. If the process is interrupted or there is an error, try restarting the device and repeating the procedure, making sure that the battery is at least 20% charged.

Using System Settings for Data Migration

If you can't do an action through the contact app, you can use deep system settings, which often help when the contact interface is simplified or contains translation errors, and the path to the desired function is through the main settings menu of the smartphone.

Go to Settings → Applications → All Apps. Find the Contacts system app (can be called Contacts or have a little man logo) and select Import/Export Contacts from the app menu, where the functionality duplicates the features of the main menu, but sometimes works more stable when there are software failures.

In the menu that opens, select “Import with” SIM-The system can request confirmation of action. If you have two SIM cards, carefully select the one to count the data from. An error in choosing a slot will lead you to search for non-existent numbers on the active SIM.

Once you select a source, you will be prompted to select a target folder or account. Google Contacts is recommended. This will ensure cross-platform: your numbers will be available not only on Xiaomi, but also on tablets, computers or phones of other brands if you log in to your account.

Solving problems with coding and duplicates

A common problem when transferring data from older phones, especially push-button models from Nokia, Sony Ericsson or Samsung of the past, is the wrong encoding of names. Instead of Cyrillic letters, you can see a set of incomprehensible characters or question marks, this is due to the fact that older phones used different text encoding standards (GSM 7-bit, UCS2, etc.).

To remedy the situation, sometimes it helps to re-import with a choice of another encoding, if this option is available in advanced settings, but most often it is easier to use third-party converter applications or copy the numbers to an intermediate Android smartphone that correctly recognizes the encoding, and from there already transfer to Xiaomi.

Another common problem is duplication of records: If you previously synced numbers with Google and now imported them with SIM, one person may have two or three cards with the same name. Xiaomi's system is able to combine them automatically, but sometimes manual intervention is required.

To clear the duplicates, go to the Contacts app, open the settings menu, and find the item “Combine Repeated Contacts.” The system will offer a list of potential duplicates. Automated pairing is secure and will not cause data loss, since it only links different entries into one card, saving all the numbers.

Syncing with a Google account as an alternative

Instead of copying directly from SIM-The experts recommend using cloud synchronization, which is a modern standard that eliminates the dependence on physical media. If you have the option to insert a SIM card into any Android phone, it’s best to copy the numbers to it first, and then, by logging into the same Google account on Xiaomi, get the entire phone book instantly.

The process of setting up sync on Xiaomi is simple. Go to Settings → Accounts and Sync. Select your Google account and make sure the switch opposite to Contacts is active. If sync has been disabled, turn it on and click Sync.

The advantage of this method is that Google Contacts is smarter than any SIM card, which not only saves your name and number, but also your email, address, birthdays, even photos, and also protects you from data loss in the event of a SIM card breakdown, which is often caused by chip wear.

If you’ve just bought a new phone and haven’t set up your old one yet, this is the perfect time to get yourself used to cloud storage.In the future, it will save you hours of time when you replace your device.Just make sure the new device has the same account that was used on the old one.

Work with VCF-file-transfer

For advanced users or when transferring a huge number of records, the vCard (.vcf) file method is ideal, a universal standard for electronic business cards and is supported by almost all devices, from iPhones to desktop computers.

The method is to export all contacts from the SIM card (or old phone) into one file, transfer this file to Xiaomi and then import it. To create such a file on an old device, you need to select Export from the contacts menu and save the file to internal memory or send it to your messenger / mail.

Once you have a contact.vcf file on Xiaomi, just open it. The system automatically recognizes the format and suggests adding the contacts found to the phone book. This is the cleanest way, since it allows you to preview the file and avoid importing garbage records.

⚠️ Note: When importing from VCF-Be careful if the file contains thousands of records, the process can take several minutes, and at this time the phone may run slower, do not interrupt the process or close the import application before the success message appears.

.vcf files are also convenient because they can be edited on a computer, and there are programs and online services that allow you to open such a file in Excel, sort numbers, remove spaces or correct names, and then download back to the phone in a corrected form.
