Changing your smartphone is often stressful, as the new device comes with the fear of losing important data. Among all the information, the phone book is the most valuable asset to keep intact. Many users who switch from button phones or other operating systems wonder how to copy contacts to a SIM to avoid losing a single number.
The modern MIUI shell installed on Xiaomi devices has its own features of working with an address book. Unlike older systems, cloud storage is the priority here, but the portability to a physical communication card has not gone away. It remains relevant for those who change devices or just want to back up on a removable medium.
In this guide, we will take a detailed look at all the ways to transfer data, look at hidden settings and answer frequent questions, learn how to avoid duplication of records and what to do if the standard method did not work. The instruction is suitable for both budget models Redmi, and for the flagship Xiaomi Mi and Xiaomi 13/14 series.
Device preparation and verification SIM-map
Before you start manipulating the phone book, you need to make sure that the SIM card itself works correctly. If the card is damaged or not supported by the phone module, the copying process will not be possible. Put the SIM card into the slot and wait for the network icon to appear in the status bar.
Modern Xiaomi smartphones often use a combined tray, where the second slot can work either as a place for the second SIM or as a slot for a microSD memory card. Make sure the card is installed correctly and determined by the system. → The phone. → All parameters and check the status SIM-map.
It's also worth checking where your numbers are stored right now. If they're scattered across multiple sources (Google account, phone memory, old SIM), the result may not be complete, and it's best to first collect all the records into a single source, like a device memory or a cloud, and then copy them all at once.
It is important to understand the difference between storage formats. SIM-The card has a limited amount of memory and often crops long names or does not save additional numbers (working, fax) for a single contact.
⚠️ Note: Before starting a mass copy, make sure that SIM-The old cards can only hold 250 contacts, while the new ones can hold up to 500.
Standard way to copy through contact settings
The simplest and most reliable method for copying contacts to a SIM is built directly into the Contacts app, which requires no third-party software installation and works consistently on all versions of MIUI and HyperOS.
To start, open the standard Contacts app (a yellow icon with a human silhouette) and in the upper right corner of the screen you will see a three-dot icon or a gear, which is the settings menu. Click on it to reveal the list of available actions.
In the menu that opens, look for the item “Import and export contacts”, which is where all the tools for working with the phone book are hidden, and the system will suggest choosing the source of data (where we copy from) and the destination (where we copy).
- 📱 Select the item "Export to" SIM-card, if you need to transfer numbers from the phone memory.
- 📇 Select "Import with" SIM-cards" if you insert a new SIM and want to save numbers from it to the phone.
- ☁️ The option “Export to Mi Cloud” will allow you to create a cloud backup, which is more reliable than a physical card.
Once you've selected an action, the system will ask you to confirm the operation. SIM-card, phone will warn you of possible loss of data (long names or second numbers.
☑️ Checklist before copying
The time of the process depends on the number of recordings. Don't turn off the screen or turn off the application until the message of successful completion appears. If the process is interrupted, the data may become corrupted.
Import and Export through Google Account
An alternative and often more convenient way is to use the Google ecosystem, with many Xiaomi users opting to sync their contacts with Gmail, as it allows them to recover numbers even when they are completely lost or broken. SIM-map.
To copy contacts using this method, make sure your Google account is added to your phone's settings. Go to Settings → Accounts and Sync. Find your Google account and make sure that the sync box is in front of the Contacts item.
Once synchronized, all the numbers from the phone's memory will be transferred to the Google cloud, and you can easily transfer them to the Google cloud. SIM-Open the Contacts app, click on the menu (three dots) and select Settings» → «Contact Import. Please provide your Google account as your source and your destination — SIM-map.
| Parameter | Phone memory | SIM-map | Google Account |
|---|---|---|---|
| Memory capacity | Unlimited. | Limited (250-500) | Unlimited. |
| Length of name | Anybody. | Frequently circumcised | Anybody. |
| Additional numbers | There is. | No (usually number 1) | There is. |
| Photo of contact | There is. | No. | There is. |
Using a Google account is especially useful when switching to a new smartphone. You will not have to suffer with a transfer to the SIM - just enter the username and password, and the entire phone book will load automatically.
What to do if your contacts are not synchronized?
Working with duplicates and combining records
A common problem when copying contacts to Xiaomi is that you get duplicates, and this happens when you store the same number in your phone's memory, your SIM card, and your cloud, and you see multiple names when you call.
The MIUI shell has a built-in tool to combat this: Open the Contacts app, click on the settings menu, and find "Combine Repetitive Contacts." The system will automatically scan the database and suggest combining records with the same numbers or names.
You can choose to automatically merge all the duplicates you find or check them manually, and manual mode is recommended so that you don’t accidentally merge different people with the same names (for example, two “Alexanders” with different numbers).
- 🧹 Select Auto-Association for quick cleaning of obvious repeats.
- 🔍 Use manual mode to thoroughly check the base before exporting.
- 🗑️ Delete old records from SIM-cards after successful copying to the phone to avoid confusion in the future.
After cleaning the database, the copying process to the SIM card will be cleaner, and you will be sure that only relevant and unique numbers are on the media.
Using the Mi Mover app for migration
If your goal is not just to save numbers for the SIM, but to completely move from the old phone to the new Xiaomi, you should use the specialized Mi Mover application. It is preinstalled on all devices of the brand and allows you to transfer contacts, photos, apps and settings without using the device. SIM-map-in-way.
To work, both smartphones must be enabled. On the new phone, launch Mi Mover and select "I am the recipient." On an old device (whether Android or iPhone), install the app from the store or scan it. QR-code that will appear on the screen of the new phone.
Unlike copying to a SIM card, Mi Mover transmits full contact profiles — with photos, email addresses, job titles and assigned ringtones — a much more modern and reliable way to migrate data.
💡
Expert advice: If you’re switching from iPhone to Xiaomi, use the “Move to iOS” app in reverse – first shift your contacts to another brand’s Android smartphone and from there to Xiaomi, or use the web version of iCloud to export in vCard format, which can then be imported into Google Contacts.
However, if you only have one phone on hand and you just need to make a backup, the SIM card or cloud method is the only solution.
Solving common problems and errors
Sometimes users are faced with a situation where the copy button is inactive or the process ends in an error, most often due to overflowing memory. SIM-map or formatting a contact file.
If the system writes "Memory" SIM-The map is filled, you need to delete some of the old records directly from the SIM, you can do this in the same import / export menu, selecting the source «SIM-map" and delete the unnecessary numbers. Once the space is vacant, repeat the copying procedure.
Another reason is format incompatibility, where some carriers use old storage standards that don't support Cyrillic in names, in which case, when you copy, names can turn into question marks or a set of characters.
⚠️ Note: If contacts are not displayed correctly (crackers) after copying, don’t try to edit them on the SIM card. copy them back to your phone’s memory, edit there, and use cloud sync instead of a physical card.
Also, the problem may be access rights, so make sure that the Contacts and Phone app is allowed to access the storage and SIM-You can check this in the Settings section. → Annexes → All applications → Contacts → Access rights.
💡
The main cause of copying errors is overflowing memory. SIM-map or outdated data storage format on the communication card itself.
