How to synchronize contacts with SIM card on Xiaomi phone

Switching to a new smartphone or recovering data after a system reset is often a real challenge for the user, especially when it comes to the safety of a personal phone book. Owners of Xiaomi, Redmi and Poco devices face the need to transfer records stored on an old SIM card to the internal memory of the gadget or to the cloud service. Modern versions of the MIUI shells and the new HyperOS offer flexible tools for managing data, but their interface can change, which sometimes causes difficulties for those who are accustomed to standard Android.

The main difficulty is that by default, new smartphones often offer to save numbers directly to a Google or Mi Account account, ignoring the physical card of the carrier, which is done for security, since storage on a SIM card is considered an archaic and limited method that does not allow you to save long names or additional fields like email.

In this article, we will discuss in detail the algorithm of actions that will allow you to quickly and losslessly transfer all records, you will learn not only about standard methods through the settings menu, but also about the nuances of working with dual-sim devices, as well as how to solve typical errors when the phone “does not see” contacts on the map.

Preparation of the device and verification of the SIM card

Before you start manipulating the software, you need to make sure that the physical health of the data carrier. Old SIM cards, especially those that have been used for more than 5-7 years, can have a worn chip or be cropped manually, which sometimes leads to unstable contact with the tray of the Xiaomi smartphone. If the card is poorly read, the system can display only part of the records or not show them at all, which creates the illusion of data loss.

Remove the tray, gently wipe the SIM card contacts with a soft dry cloth and paste it back until the characteristic click. After turning on the device, note the network status at the top of the screen. If you see 4G, LTE or 5G icons, and the signal level, then the physical connection is installed correctly. If you display the message "No SIM card" or "Incorrect SIM card", the software transfer of contacts is impossible until the hardware problem is fixed.

⚠️ Warning: Never try to retrieve or insert a SIM card when it is turned on unless your Xiaomi smartphone supports the Hot Swap feature. While most current models allow it, the risk of damaging the power controller or software-hanged tetap modem exists, which will require a reboot.

It is also worth checking whether the phone book is blocked on the card. PIN-Some carriers or previous owners may have installed the protection that is requested every time you turn on your phone, and without the correct code, access to your contacts will be blocked by Android security. Make sure you know this code, or turn it off in the security settings before you start importing it.

Import contacts through the standard “Contacts” application

The most common and reliable way to transfer recordings is to use the built-in Contacts app, which is preinstalled on all Xiaomi smartphones. The program interface may vary slightly depending on the version of MIUI (12, 13, 14) or HyperOS, but the logic of actions remains the same.

In the menu that opens, you'll need to find the settings section, which is usually hidden behind three dots in the top right corner or behind the gear button, and in the list that opens, look for something that might be called "Import and Export Contacts" or simply "Contact Management," and that's where all the tools for working with external media are concentrated.

Once you select the import point, the system will suggest you specify the source of the data, in our case it will be Import from a SIM card. If you have two SIM cards installed on your device, the smartphone will suggest you choose which one to read the data from. Choose the desired slot (SIM 1 or SIM 2), and the process will begin automatically. The system counts all available records and will suggest choosing a place to save them.

• 📱 Google account is the best choice for sync, allowing you to restore numbers on any device.
• ☁️ Mi Account – Xiaomi cloud service, convenient for users of the brand ecosystem.
• 📂 Device memory – saving locally, without being tied to the cloud (less reliable when losing your phone).
• 📞 Phone – Standard Android storage available only on that particular device.

It's important to understand the difference between these options. Save to a Google account provides automatic synchronization: if you lose your phone, new numbers will appear on your tablet or computer instantly. Local storage requires manual backup. Once you select the target storage, confirm the action and all the records will be copied. The process takes from a few seconds to a couple of minutes depending on the number of contacts.

Saving contacts to your Google account guarantees their automatic recovery on any new Android smartphone after authorization.

Working with two SIM cards: the nuances of MIUI and HyperOS

Xiaomi smartphone users often use devices in two active cards, which creates a specific situation when importing data. Unlike some other manufacturers, the MIUI shell and HyperOS clearly separate the data streams from different slots. When trying to import, the system will always ask for clarification of which card (SIM 1 or SIM 2) should be considered information. A choice error will result in the contacts from the second card remain intact.

If you have to move data from both cards, you have to do it twice, so you pick the import from the first SIM card, you finish the process, and then you do the same thing for the second card, and the system doesn't offer to combine this process into one "Import from all cards," so manual switching is necessary, and this is done to avoid duplication of records if the same people's numbers are stored on different cards.

It is worth noting that when importing from two cards, contact names can conflict. If the first card has Alexei and the second card also has Alexei, but with different numbers, the system can create two separate records or, in rare cases, try to combine them if the numbers match. After the procedure, it is recommended to go to the application and check the list for duplicates, using the built-in "Combine duplicates" function in the contact settings.

⚠️ Note: When importing from two different SIM cards, keep a close eye on the process. If you interrupt the operation in the middle, some contacts may not be recorded, and already copied ones will remain.

Alternative methods: Google Account and file sharing

While direct import via the Contacts app is basic, there are other ways to migrate data that may be more convenient in certain situations, such as if you have access to a computer or other smartphone, you can use sync via Google Contacts. This requires you to first upload your contacts from your SIM card to any Android smartphone (even your old one), sync them with your Google account, and then on the new Xiaomi just log in to the same account.

This is especially effective when you want to migrate contacts to a large number of devices, or if the phone interface is in a language you don't understand well. All data is stored in the cloud at contacts.google.com. You can manage it, delete duplicates and edit numbers directly from your computer, and the changes will automatically apply on your Xiaomi phone when you have the Internet, which eliminates the binding to a physical medium.

Another option is to use the.vcf file. Some old phones or specialised PC programs allow you to upload contacts from the SIM card to a file. The resulting file can be transferred to Xiaomi via Bluetooth, Mi Drop or Mi Drop. USB-And when you open this file on your smartphone, it's going to suggest that you import the records that it contains, and it's a universal way of doing things, regardless of the phone model or the operating system version.

• ☁️ Cloud sync – requires the Internet, but allows access from any device in the world.
• 💾 File. VCF — Convenient for creating local backups and transferring the archive to another person.
• 📲 Helper apps like “Copy My Data” that transfer data over Wi-Fi directly between phones.

Alternative methods are often faster when the data is large. Direct reading from the SIM card can be slow because of the slow speed of the card chip, while transmission over Wi-Fi or the cloud occurs at the speed of a modern Internet connection. Choose the method based on the availability of additional devices and network stability.

Common mistakes and ways to solve them

In the process of synchronization, users can face various technical problems, one of the most common is the message “Contacts not found” or an empty list when choosing imports with the SIM. This often happens if the contacts on the card itself are damaged or recorded in a format that a modern Xiaomi smartphone cannot interpret correctly.

Another common problem is the character limit: older SIM cards often have a limit of 15-20 characters for a name; when imported into a smartphone, long names may be cropped or displayed incorrectly (for example, instead of "Alexander" will be "Alexan"). This is not a system error, but a technical limitation of the carrier itself. This can only be fixed manually by editing each contact after import.

If the phone writes “Import Error” or the process is hanging in the middle, check the free space in the device memory and in the selected account. The overflowing cache of the Contacts app can also cause crashes. → Annexes → All applications → Contacts → Clear the cache. Don't confuse this with a data cleanup that will delete the entire phone book.

⚠️ Note: If contacts are displayed after import but no name is identified, check the display settings in the Contacts app. There may be a Phone Contacts Only filter that hides numbers stored on the SIM card or other sources.

In rare cases, the problem is incompatible name encoding (Cyrillic can turn into Cracosabras), which is typical of very old cards rearranged from push-button phones of the early 2000s, where only manually rewriting problem names or using an intermediate step through a.vcf file with the correct UTF-8 encoding will help.

Organization and security of the contact book after transfer

Once the import procedure is completed successfully, it is critical to ensure the security of new data. The SIM card is no longer a reliable storage: it is easily lost, broken and has a small volume. The most reliable way to save contacts is to permanently place them in a Google or Mi Cloud account with two-factor authorization enabled. Make sure that synchronization in account settings is active and is marked with the Synchronized icon.

It's also worth taking time to clean up. Over the years, the phone book accumulates many duplicates, old numbers, and entries with names like "Subscriber 1." The Xiaomi app can automatically find duplicates. Go to the contact settings and select "Combine Repetitive Contacts." The system will suggest combining entries with the same names or numbers, which will make the book cleaner.

Remember to back up regularly. Even if contacts are stored in the cloud, having a local copy of a.vcf file on your computer or flash drive will never be superfluous.This will protect you from situations where your Google account may be blocked or deleted. Regularly exporting contacts to a file takes less than a minute, but can save uptime to reconnect in the future.

💡

Set a regular reminder every six months to check the relevance of contacts and make them backup in the file. This will take 2 minutes, but save you from losing important numbers when your phone breaks.
