How to Keep Contacts with Xiaomi: The Complete Guide

Changing a mobile device or switching to a different data plan often puts the user in the position of having to move the phone book. Owners of Xiaomi, Redmi and Poco smartphones can face a situation where all the numbers are recorded in internal memory or Google account, and the physical SIM card is empty, which creates the risk of data loss when the gadget breaks or resets to factory settings.

Modern operating systems, including MIUI and HyperOS, offer cloud storage by default, which is more convenient but requires the Internet. However, the ability to copy records directly to the carrier chip remains critical for many, and in this article we will discuss in detail how to keep contacts on SIM on Xiaomi using built-in tools without installing third-party software.

The procedure doesn't require root rights or complex code manipulations, you just need the smartphone itself, a free-space SIM card, and a few minutes of time, and we'll look at the standard path through the Contacts app and the alternative methods that come in handy if the standard menu is hidden by the manufacturer.

Preparation for data transfer and capacity check

Before you start copying, you need to make sure that the operation is technically possible. Old or stripped-down SIM cards have a limited amount of memory to store records, usually 250 or 500 cells, and if your phone book is larger, you will have to do it in several steps or select selective copying.

It’s also worth checking where your numbers are stored right now. Xiaomi’s default ecosystem uses sync with a Google account or Mi Cloud. If the records are scattered across multiple sources, you first need to put them together. Open the Contacts app and select the option to combine duplicates in the settings.

It is important to understand the difference between storage formats. The SIM card often only transfers the name and number, while additional fields (email, address, photo) can be lost, so backing up to the cloud before any manipulation of contact files is a mandatory security step.

⚠️ Note: When copying long names (more than one) 10-12 symbols) they can be cropped, as the SIM card standard is limited by the number of characters in the name field.

Standard algorithm for copying through the Contacts application

The main way to transfer data is built into the standard phone book application. The interface may vary slightly depending on the version of MIUI, but the logic remains the same. First, open the Contacts app on the home screen or in the Tools folder.

Then you go to the control menu. Click on the three dots in the top right corner or select the Settings tab at the bottom of the screen. In the list that opens, look for Import and Export Contacts. This is where all the tools for working with the phone book are concentrated.

In the import/export menu, select the option “Export to” SIM-The system will automatically analyze the number of records and the space available on the chip. If there are many records, the smartphone will prompt you to select specific numbers or copy all available ones.

The copying process can take anywhere from a few seconds to a minute, depending on the amount of data. Don't turn off the screen or run heavy applications at this point, so as not to interrupt the recording to the chip. Once completed, you will receive a notification of successful export.

Alternative method through system settings

In some firmware versions, direct access to export to the SIM can be hidden or changed by the interface developers, in which case you can try to find the feature through the general device settings. Go to Settings → Applications → All applications and find in the Contacts list.

There is sometimes a separate data management section inside the app menu that duplicates the main menu functions. If there is also no option, try searching by settings. Type the word "SIM" or "Contacts" into the search bar, and the system will highlight the desired menu section.

Another option is to use the old interface, and in some regions, the Classic Contacts theme is available, which brings the menu back to the way it used to be used in older versions of Android, and toggle the theme can make hidden features visible.

💡

If the standard menu does not allow export, try temporarily installing the SIM card in another slot (if there are two) – sometimes this will activate hidden menu options.

It is worth noting that in the newest versions of HyperOS, the company can completely abandon the SIM recording function in favor of cloud technologies, in which case the only way out is to use third-party utilities or export to a VCF file and then download it through another device.

Work with VCF files and cloud storage

If direct export to the card is not possible, use the intermediate format.vcf. This is a universal file containing the entire phone book. In the menu "Import and export" select "Export to storage." The file will be saved in the memory of the phone.

You can then transfer this file to a computer or other phone where the SIM recording function works correctly, and you can upload the VCF file to Gmail contacts via your browser on your PC, and then sync it to any Android smartphone when you log in.

Using the Mi Cloud or Google Contacts cloud allows you not only to save data, but also to manage it remotely. You can edit numbers, delete duplicates and group subscribers from any device with access to the Internet.

The choice of method depends on your goals. Synchronization with Google is best for daily use, as it ensures maximum data security and ease of recovery. SIM card remains a good option for temporary storage or transferring the database of numbers to another person.

Solving problems when copying

Often users encounter an error, “SIM card memory is full”, which means that the cell limit is exhausted, in which case you either need to delete old unnecessary entries directly from the SIM card through the control menu, or copy only selected contacts.

Another common problem is the encoding of names: Russian letters can be displayed as question marks or Krakozabras, due to the limited character set supported by the GSM standard for Cyrillic alphabet, which unfortunately cannot be corrected at the SIM card level.

⚠️ Note: If contact photos are missing after copying, don’t panic. SIM cards don’t technically support storing graphics files, photos stay in the cloud or phone memory.

In some cases, the system may give an error when trying to export if the SIM card is damaged or has a non-standard contact format. Try to remove and re-paste the card, making sure the contact density. If the problem persists, check the card in another device.

Import data from SIM card to new phone

Once the numbers are saved successfully to the SIM card, they can be easily transferred to any other phone, insert the card into a new device, and when the system starts up, it will often prompt the data to be imported, and if that does not happen, the process is done in reverse.

Go to the Contacts app, select Import and Export and click Import with SIM-You will be asked to choose your destination: a phone memory or a Google account, and it is recommended to choose an account so that data will not be lost in the future.

Once imported, make sure to check the integrity of the database. Make sure all the numbers are readable on site. If some of the data is lost on export, it won't magically recover when imported, so the original copy in the cloud remains your main insurance policy.

💡

A SIM card is a temporary storage medium, not a reliable storage. Always duplicate important information in the cloud.

The final step is to clear the SIM card of the copied data if you plan to use it elsewhere or just want to vacate space. SIM-map».
