How to synchronize contacts with SIM-maps on Xiaomi Redmi

Switching to a new Xiaomi Redmi smartphone or recovering data after a system reset is often accompanied by the need to move the phone book. Device owners who have previously used button phones or other brands often store all important numbers directly on the phone. SIM-But the Android operating system is in the shell. MIUI HyperOS requires the right approach to importing this data to display it correctly and use it later.

The transfer process is not always smooth due to the features of encoding or the limitations of the storage format on the SIM card chip. Often users are faced with the fact that after importing numbers are displayed without names, with cropped numbers or duplicates. Contact synchronization is not just copying, but structuring the database of your device, so it is important to follow all the steps consistently and choose the right storage location.

In this article, we will discuss in detail the standard import methods, work with Google cloud services and Mi Cloud, as well as how to solve common errors. You will learn how to avoid data loss and why storing numbers in a phone memory or account is much more reliable than on a plastic medium.

Preparation of SIM-card and checking the data format

Before you start active actions in the smartphone menu, you need to make sure that physical health is maintained. SIM-Older SIM cards could have limitations on the length of the number or the number of characters in the name, which led to errors when reading on modern Xiaomi Redmi. If the card is very old, it makes sense to request a replacement with a new one with the preservation of the number to exclude technical failures during reading.

It’s also worth checking if the SIM card itself is full of memory.The chip’s record limit is usually 250 to 500 numbers, and if it’s exceeded, some contacts may not appear on the list available for import. The storage format on the SIM card often trims long names and doesn’t support additional fields like email or address, so full synchronization is only possible after the device is transferred to memory.

⚠️ Warning: Before any contact transactions are initiated, it is strongly recommended to back up your current phone book, even if it is empty or contains few records, and this will protect you from accidental data loss in the event of a software failure.

Make sure that SIM-The card is correctly installed in the tray and is determined by the system. → The phone. → All specs → SIM-If the system sees the card but can't see the contacts, it may be written in a format that is incompatible with the current version of Android, or the card is physically damaged.

Import contacts through the standard “Contacts” application

The fastest and most reliable way to move numbers is to use the built-in functionality of the Contacts or Phone app in the MIUI shell. This method does not require an Internet connection and works locally. To start, open the Contacts app and find the control menu, which is usually hidden behind three points in the corner of the screen or accessible through the side menu.

In the menu that opens, you have to select Import Contacts, and the system will suggest you to select a data source. SIM-Once the source is selected, the phone will scan the chip and display the list of records found. If there are many numbers, the process can take several seconds.

Next, you will be asked to choose a destination for imported numbers. You are advised to choose the Phone option, or better yet, your Google account if it is added to the system. Selecting a Google account will automatically start syncing with the cloud, which is best practice for data security. Once confirmed, the copying process will begin, the progress of which will be displayed on the screen.

It is important not to interrupt the process or switch between heavy applications during importation to avoid the phone service freezing. Once completed, the system will notify you of a successful copy or report errors if some records cannot be read. Usually such records are marked as "Unknown Number" or simply missed.

Use of Google and Mi Cloud Cloud Sync

Modern Xiaomi Redmi smartphones are closely integrated with cloud services, which allows you not only to transfer, but also to secure contacts. Synchronization with Google Contacts is a priority, because it provides cross-platform. You can edit numbers from a computer, tablet or any other Android device, and changes will instantly affect the phone.

To activate this feature, go to Settings → Accounts and Sync → Google. Make sure the switch opposite the Contacts item is active. If you previously imported numbers into your phone’s memory, they will automatically load into the cloud when the Internet is turned on. Mi Cloud also offers similar functionality, but for users who change smartphone brands frequently, the Google ecosystem turns out to be more versatile.

If you use Mi Cloud, the path is: Settings → Mi Account → Sync → Contacts. Here you can choose detailed settings, for example, sync only certain groups or eliminate duplicates. Cloud storage ensures that when you lose or steal your smartphone, you do not lose important information, since it is tied to your login, not to your physical device.

When working with the cloud, it is important to monitor the status of the connection to the network. If sync is frozen, try turning on and off Flight mode or switching between Wi-Fi and mobile Internet. Sometimes cleaning the cache of the application “Google Play Services” or “Sync Mi” through the application management menu helps.

Solving problems with encoding and displaying names

One of the most common problems when transferring data from SIM is the incorrect display of Cyrillic alphabets. Instead of Russian letters, users see a set of characters or question marks, this is due to differences in the encoding tables that were used when writing on older phones. Modern Xiaomi smartphones use the UTF-8 standard, which can misinterpret old SIM card encoding formats.

To remedy this situation, often re-importing with a choice of another destination or using third-party applications-converters from the Play Market, specializing in reconnection, helps. However, most often the problem is solved by simply overwriting the problem numbers, if only a few records are distorted, it is faster to manually edit them, opening the contact card and saving them again.

It’s also worth checking the display settings in the Contacts app itself. Click on three dots → Settings → Contact Display. Make sure you have selected All Contacts and check the box against Phone or the corresponding account. Sometimes the contacts are successfully imported but hidden by the filter, making it seem that the import failed.

Removing duplicates and combining records

After synchronization with SIM-In maps and cloud services, users often notice that one person may have multiple contact cards. SIM, Both in Google and in the phone’s memory. Xiaomi Redmi has a built-in tool to solve this problem that makes it much easier to clean up the phone book.

To combine your records, open the Contacts app, click three dots, and select Contact Organizer (or Contact Management). In this menu, find Combine Duplicates. The system will automatically analyze the database, find matches by phone numbers or names, and suggest combining them into a single card.

The process of combining is safe: information from all the cards is summed up, for example, if one has only a mobile phone and another has a home phone and an email, after combining all this data will be in one card, which makes contact finding more efficient and eliminates confusion when calling.

⚠️ Note: When automatically combining, check the results carefully if you have contacts with the same names but different people (for example, two Alexanders with different numbers.

Regularly cleaning duplicates improves the performance of the Contacts app and speeds up search. If the built-in tool fails, you can use the web version of Google Contacts (contacts.google.com), where the “Combine and Fix” function works even more detail and allows you to manage the base from the large screen of your computer.

Comparison of methods of storage of contacts

Understanding the differences between the locations where contacts are stored will help you choose the best backup strategy. Each method has its advantages and disadvantages, which affect data availability and functionality. Below is a table comparing the main options for storing numbers on Xiaomi devices.

As you can see from the table, the storage SIM-The card is the most archaic and least functional method, and it's only suitable for transient transfer of data between devices, not for permanent use. The phone's memory is more reliable, but it ties you to a particular device.

Using a Google or Mi Account provides the most flexibility, you can change your phone at any time just by logging in to your account, and the entire phone book will recover in seconds, and cloud services allow you to restore remote contacts, which is impossible when storing on SIM.
