How to save contacts on the SIM card in Xiaomi Redmi: the complete guide

Owning a Xiaomi or Redmi smartphone often involves the need to migrate data, especially when switching from a button-down phone or an old Android device.The phone book is one of the most valuable assets, the loss of which can be a serious problem. Users often wonder how to transfer existing records to the SIM-card to secure them or use as a temporary buffer when changing devices.

Modern shell MIUI (HyperOS offers flexible tools for managing records, but the algorithm for their operation is different from stock Android. Standard copying procedure may not be obvious to a beginner, since the system by default tends to store all data in a Google or Mi Cloud account. Local storage and physical storage SIM-The map often fades into the background, but remains critical for many use cases.

In this article, we will discuss the process of data transfer, consider the nuances of working with.vcf files and answer frequent questions that arise when trying to save numbers to the operator’s chip.

Preparation of the device and check of condition SIM-map

Before you start manipulating the phone book, you need to make sure that the card itself works correctly. SIM-The card has limited memory, which usually does not exceed 250 records, and often imposes limits on the number length and the presence of additional fields. → The phone. → All parameters. → SIM-map.

If the card is not defined as stable or displayed as “No network”, the data retention procedure may not be correct or interrupted. In some cases, especially with older cards, the amount of available memory may be significantly less than the declared GSM standard.

It's also worth checking if the map isn't crowded with previously saved records: Old "junk" contacts from previous phones can take up precious space. SIM-A card before you start is a good tone for a digital hygienist.

⚠️ Note: Before starting mass copying, be sure to back up your current contacts in Google Account. In case of a process failure, you can easily recover lost data without losing any number.

Make sure your Xiaomi Redmi has an up-to-date connection status. Although the copying process does not require the internet, having a stable signal may be required to identify some service numbers if they are present in the list.

Import contacts from the cloud or phone memory to SIM

The main method of transferring data to MIUI is through the standard Contacts app, a system solution that is integrated into the shell and does not require any third-party software installation. First, open the Contacts app on the home screen or in the Tools folder.

The interface may vary slightly depending on the version of MIUI, but the logic remains the same: You need to find the control menu, which is usually hidden behind a three-dot icon or gear, and this menu contains a key import and export function.

After selecting the Import/Export point, the system will suggest choosing a data source, which can be your Google account, Mi Cloud, internal device memory or even other data sources. SIM-If you have two of them on your smartphone, choose the source where your numbers are right now.

In the next step, the system will ask where exactly to save the data. SIM-If you have two SIMs on your device, carefully specify the one you plan to rewrite the data to. The process can take anywhere from a few seconds to a couple of minutes depending on the number of records you have.

It is important to understand that when importing SIM-The map is truncated, and fields like "Email," "Address," "Office," and even the second phone number will be permanently deleted because the storage format on the operator's chip does not support them, and only the name and one primary number will be saved.

Using VCF files for backup and transfer

An alternative and often more reliable way to save data is to use.vcf (vCard) files, which allows you to create a complete digital cast of your phone book that can be stored on a flash drive, sent via instant messengers or stored in the cloud.

To create such a file in the Contacts app, select Export to File or Export to Storage. The system will form a single file containing all the selected records. This is especially useful if you need to transfer contacts to a device of another brand, such as an iPhone or Samsung, where procedures may differ.

The vCard file retains the entire data structure: avatars, additional numbers, email addresses and rings, making it the preferred format for archiving, as opposed to limited data. SIM-map.

To recover data from a file, just find it in the file manager (usually in a folder). MIUI/Contacts or Downloads) and click on it. The system automatically prompts you to import the entries contained therein to the selected account or to the selected account. SIM-map.

💡

Keep the vCard file not only in internal memory, but also copy it to a computer or external media. The internal memory of the smartphone can fail, and then the copy will be stored on the computer. SIM-The map will be the only salvation, but it will be incomplete.

When working with files, be careful about duplicates. If you import a file that already has numbers saved on the phone, the system can create duplicates. MIUI usually offers a merge feature, but it is better to control this process.

Storage methods comparison: SIM, Google or Device Memory

Users often argue about where to store contacts, and each method has its own advantages and disadvantages to consider depending on your security and mobility needs.

SIM-The card provides physical independence from accounts and the Internet. You can take the card out, paste it into any phone (even a button), and the numbers will be in place. However, as mentioned, it is a deaf format with no synchronization and minimal data.

Google Account is the gold standard for Android users, providing instant synchronization between your phone, tablet and computer, and if you lose or break your smartphone, just enter your username and password on your new device, and all contacts will recover in seconds, and Google also makes it easy to edit your records from the big screen of your PC.

Device memory (local storage) is an intermediate option. Data doesn't go to the cloud, which privacy advocates like, but if you reset or break your phone without exporting it beforehand, you risk losing the entire database.

For maximum reliability, it is recommended to combine methods: keep the main base in Google Contacts for convenience and synchronization, and on the Internet. SIM-The card rewrite only the most critical minimum - the numbers of emergency services and immediate relatives, which may be needed if the smartphone is lost, and the new one is not yet configured.

💡

The optimal strategy is to store the main database in the Google cloud for daily use and synchronization, with periodic backups in VCF format on an external medium.

Solving problems with visibility and contact display

A common problem after transferring data to Xiaomi Redmi is that contacts are available, but they are not visible in the call list or they are displayed incorrectly. SIM-map.

To fix this, open the Contacts app, click on the menu (three dots or bars) and find Settings or Contact Display. In the list that opens, make sure the box is next to the item «SIM-If you select the "Phone Only" option, the numbers from the SIM will not show.

Another reason could be duplicates: If the same number is saved on both Google and SIM, MIUI can combine them or show them as two different contacts with the same name.

It's also worth checking the encoding of names. When you transfer from older phones (especially push-button Nokia or Samsung), names can turn into character sets or "crackers." This is due to differences in encoding (UTF-8 vs. old standards), unfortunately, it's hard to fix this massively - it's easier to re-select names manually or use third-party vCard editors on a PC.

⚠️ Note: If the contact names appear as a set of characters after transferring, don’t rush to delete them. Try changing the input language or encoding in the phone’s settings, although this problem is less common in modern versions of Android.

In some cases, cleaning the cache of the Contacts and Phone app helps. Go to Settings → Apps → All Apps → Contacts → Memory → Clear the cache. The data will not be deleted, but the list can be updated correctly.

Removing duplicates and cleaning the phone book

After several import and export cycles, the phone book can turn into a mess of duplicates. Xiaomi Redmi has a built-in tool for putting things in order that works surprisingly well.

Go to the contact settings and find Clear Repetitive Contacts (or “Combine Repeated Contacts”). The system will analyze the database, find numbers that occur more than once, and suggest combining them into one card. This is secure and stores all the data associated with the number.

Hand-cleaning is also important, and you go through the list and remove the old numbers that are no longer relevant, and it will not only make room, but it will also make it faster to search for contacts. SIM-maps where space is physically limited.

Remember that removing contact with SIM-The maps are instantaneous and can’t be recovered through the cart (unlike Google Contacts, which has a 30-day archive.

Regular maintenance of a phone book is a sign of a competent user, which takes a couple of minutes a month, but saves you from the hassle when you need to find the right number urgently.
