Switching to a new smartphone or a simple replacement SIM-The card often challenges the user to carry the entire phone book. Owners of Xiaomi, Redmi and Poco devices may encounter shell features MIUI It's a little bit of a problem, or HyperOS, where importing and exporting data is a little bit of a nuance. Modern Android operating systems offer a lot of synchronization options, but physical storage of numbers on a SIM chip is still relevant for many people.
In this article, we will discuss how to copy your contacts to SIM on Xiaomi so that your data does not disappear when you change your device. We will look at the regular system tools, work with a Google account and solve the typical problems that arise when transferring records. Understanding these processes will allow you to feel confident when working with an address book.
It is worth noting that the capacity SIM-The card is limited and cannot store full versions of contacts with photos, email addresses and additional numbers, but for basic preservation of names and main phones, this method remains reliable and versatile, independent of the availability of the Internet or company servers.
Preparation of the telephone book for transfer
Before you start copying, you need to make sure your records are in the correct storage. Often users don't know that their numbers are stored in your phone's memory or account, not on your SIM card. First, open the standard Contacts or Phone app on your Xiaomi.
You need to check where the data is stored, and if you see contacts linked to a Google account or a Mi Account, you'll need to export them to the internal storage and then transfer them to the chip, which is an important step, because direct transfer from the cloud to the SIM card in one click is often not available.
- 📱 Open the Contacts app and go to the display settings.
- 📂 Make sure you select all contacts, not just a specific group.
- 🔍 Check for duplicates that can take up extra space on the SIM card.
⚠️ Attention: SIM-If your phone book is much larger, you can't copy all the numbers at once, you'll have to choose the most important ones.
For ease of management, you can use the "Contact Management" feature, which includes cleaning and sorting tools, cleaning duplicates will save precious space on the media, and you should also pay attention to the format of saving names, since older SIM cards may not support long names or special characters.
Exporting contacts from phone memory to SIM
The main method of transferring data to Xiaomi is through an integrated management menu, which does not require an Internet connection or third-party applications. The algorithm may vary slightly depending on the version of MIUI, but the general logic remains the same for all models.
First, you need to go to the import/export menu. To do this, open the Contacts app, click on three dots in the corner of the screen, or select the Contacts tab in the top menu. Here we are interested in Import/Export Contacts. The system will suggest you select a data source.
Contacts → Menu (three points) → Import / export → Export to SIM-cardAfter selecting the source (Device Memory or Google Account), the system will ask you to confirm the action. If there are many contacts, the process can take several seconds.
☑️ Checklist before export
In some cases, the system may suggest selecting specific contacts to copy if the number exceeds the SIM card limit. Be careful when choosing, as you will have to enter the missing numbers manually.

Working with Google Account and Synchronization
Xiaomi’s modern smartphones are closely integrated with Google’s ecosystem. Using cloud storage is the most reliable way to store data, but sometimes it requires a physical transfer to a SIM card. If your contacts are stored in the cloud, direct export to a SIM card may not be available without an intermediate step.
You may need to export data from the cloud to a.vcf file first, then import it to the device’s memory, and then transfer it to the SIM card. However, often just allow synchronization, and the phone will offer management options.
- ☁️ Go to your phone settings and select “Accounts and Sync».
- 🔄 Click on your Google account and make sure the Contacts slider is activated.
- 💾 Wait for the synchronization to end before exporting.
Google Contacts also allows you to edit information massively through the browser on your computer, which is convenient if you need to quickly delete the extra or combine the entries before writing to the SIM card, after cleaning in the cloud, the changes will automatically affect the smartphone.
| Parameter | Phone memory | Google Account | SIM-map |
|---|---|---|---|
| Capacity | No restrictions. | No restrictions. | Up to 250 records. |
| Data data | Photo, email, addresses | Photo, email, addresses | Name and number only |
| Dependence | Just this phone. | We need the Internet. | Independent. |
| Security | Medium | Tall. | Low (may be lost) |
It's important to understand the difference between these vaults. The SIM card doesn't support the retention of Cyrillic names in some older formats, so when exporting, names can be displayed with transliteration or question marks. This is a technical limitation of the carrier, not a smartphone error.
Import contacts from SIM card to new phone
The situation when you need to do the reverse of reading data from the SIM card to the new Xiaomi, is even more common. This is the standard procedure when you first set up the device. After installing the SIM card in a new slot, the system often suggests copying the contacts.
If no automatic offer appears, follow these steps manually. Go to the Contacts app, select the import/export menu, and click Import with SIM-The system will ask where to save data: in memory of the phone or in Google account.
It is recommended to choose to save your Google Account or phone memory, as this allows you to save full versions of the cards with photos and additional fields. Direct recording on the new phone SIM card is not required and even undesirable due to the risk of data loss.
⚠️ Note: When importing with SIM-All the numbers are stored as separate records, and if you already have similar numbers in your memory, duplicates may be created that you have to manually eliminate.
The import process is quick. Once completed, check the phone book. If the numbers are displayed without names (numbers only), it means that the names on the SIM card were not saved or damaged, in which case they can only be restored from the backup if it was made earlier.
💡
Always copy your contacts with SIM-card in the memory of the phone or cloud immediately after installation, so as not to lose data when the card breaks.
Solution: Contacts are not copied or missing
Xiaomi users sometimes face a situation where copying fails. One of the common reasons is the overflowing memory of the SIM card. Unlike flash memory, every byte counts, and the old record formats take up more space.
The problem can also be physical contact: If the SIM card is old or has scratches on the chip, the smartphone can read it with errors. Try gently wipe the chip with a soft cloth and insert the card back before the click. Make sure it lies right in the tray.
- 🚫 Memory is full: Remove some old or unnecessary numbers directly from the SIM card via the control menu.
- 🔒 Access error: check if it is installed PIN-SIM card code that blocks the recording (although it usually only blocks reading).
- 📉 Number format: Some operators or older cards do not support international recording format, try changing the display format in the settings.
If contacts are missing after the MIUI update, don't panic. Often they're just hidden by the display filter. In the Contacts app, click three dots and select Contacts to Display, then tick All Contacts, which will return the missing records to the screen.
Alternative methods of backup
Relying on a SIM card alone in 2026 is no longer a good idea, and the amount of information we store has long been beyond the capacity of the SIM card, and Xiaomi owners are looking for a better solution to use the built-in Mi Cloud or third-party apps.
The Mi Mover app allows you to quickly transfer all data, including contacts, messages and photos, from your old phone to the new Xiaomi without using the Internet, via a direct Wi-Fi connection, which is much faster and more reliable than rewriting to a SIM card.
You can also export to a.vcf file. This file can be sent to a messenger, saved to a flash drive, or uploaded to any file sharing service. This file contains a full copy of the phone book and has no volume restrictions, unlike a SIM card.
💡
Keep your contact backup file (.vcf) not only in the cloud, but also on your computer or external drive, which is the gold standard for data security.
Regularly backing up through Google One or Mi Cloud ensures you don't lose important numbers even if your smartphone is completely broken.Setting up automatic sync takes a couple of minutes, but saves you from hours of wasted time in the future.
