Owning a smartphone from Xiaomi often involves the use of two SIM-This is especially true for separating work and personal calls or using different tariff plans. Standard setting of the gadget involves a single ringtone for all incoming calls, which can create confusion when you are in another room or busy with an important business. Personalization of sound for each number allows you to instantly determine which line the call is coming to without taking the phone out of your pocket.
The process of installing individual tunes on MIUI or the new HyperOS has its own nuances that are not always obvious to beginners. Unlike many other manufacturers, the system from Xiaomi requires certain actions to separate audio streams of contacts. The key point is that you have to create separate contact cards for each SIM card, even if it is the same person.
In this guide, we will take a look at all the steps of setting up, from preparing audio files to fine-tuning call settings. You will learn how to avoid common format conversion errors and why a standard file manager may not see the tracks you want. We will also look at the contact details to keep your phone book clean and structured after all the changes.
Preparation of audio files and support formats
The first step before you install a tune on Xiaomi on different SIMs, you need to make sure that your audio files meet system requirements. Android Operating shell in conjunction with MIUI natively supports MP3, AAC, M4A and OGG formats. However, if you downloaded the ringtone from an unverified source, it may be in the format of FLAC or WAV, which the system does not always accept as a system call without prior processing.
You can use built-in tools or third-party apps to check and convert files. It's important to understand that sound quality directly affects the volume of playback in noisy environments. Too quiet recordings with low bitrates may simply not be heard when the phone is in the bag. It's recommended to use files with a bitrate of at least 128 kbps for clear and legible sound.
💡
Use online converters or editorial apps to crop the track up to 30-40 seconds.Long intros can be cropped off automatically by the system and you just won't hear the start of the melody.
Once prepared, files must be placed in the correct directory. Although modern firmware versions allow you to select tracks from any folder, the classic method of placing them in the root of internal memory or in the Ringtones folder remains the most reliable, ensuring that the system immediately sees the file in the list available for installation.
Why are some files not listed in the list?
Duplicate contacts for line separation
The main technical feature that allows Xiaomi to put a tune on different SIMs is the logic of the phone book. The system binds the individual ringtone not to the phone number itself, but to a specific record in contacts, which, in turn, is tied to a specific specific record in the contacts. SIM-This means that for one caller who can call you on both numbers, you need to create two separate records.
The process of creating duplicates is as follows: You open an existing contact, copy its data, and create a new record. In the first record, you specify the number assigned to the first SIM card and select the appropriate ringtone for it. In the second record, the number of the second SIM card and another sound file. Attention: when importing contacts from the cloud (Google or Mi Cloud), these records can be combined again, so it is recommended that you store backups locally or be ready to reconfigure.
- 📱 Open the "Contacts" application and find the right subscriber.
- ✂️ Copy name and other data, create a new contact with the same name, but add a prefix (for example, "Ivan (Worker)" and "Ivan (Personal)").
- 📞 Enter in each contact only the number that relates to the corresponding SIM card.
- 🎵 Assign a unique tune to each of the created recordings through the editing menu.
This allows you to manage notifications flexibly, so you can immediately understand what you're worried about, just by sound, and it also allows you to adjust different vibration modes or visual notifications for different communication lines, which improves the usability of the device in everyday life.

Step-by-step: Assigning a ringtone through settings
There are two main ways to set the melody on a SIM in Xiaomi: through the global audio settings and through the contact menu itself. The first option is suitable if you want to set the standard sound for all calls coming to this particular one. SIM-card, regardless of who is calling (unless the number is in contact with the individual setting).
To start, go to the device settings menu, and you'll need to find the audio section, and the path may vary slightly depending on the firmware version, but the logic remains the same. Choose the SIM card you want from the list and assign it your preferred track, and this action will set the "basic" sound for the line.
Settings → Sound and vibration → Phone Call → SIM 1 (or SIM 2)However, to do the "different tunes to different SIMs" task for specific people, you need to act through a contact card. Open a contact, click on the edit button or three dots in the corner of the screen. In the menu that opens, find "Rington" or "Calling Melody." The system will suggest you choose a track from the list or a file manager to find the downloaded audio.
💡
Assigning a melody through a contact card takes precedence over the general settings of the SIM card. If the contact is given its own sound, it will be played out, ignoring the overall ringtone of the SIM card.
After selecting the file, remember to save the changes. Check the health is carried out by a test call. If the sound has not changed, make sure that you keep contact with the exact number from which the call is coming, and that there are no extra numbers or symbols left in contact that could bring down the recognition system.
Configure via the “Themes” application and third-party utilities
In the Xiaomi ecosystem, the Themes app is a powerful customization tool, and it allows you not only to change icons and wallpapers, but also to manage sound design. In some regions and firmware versions, you can download ringtones through this app, which are then available on the system, which is especially useful if you want to download a popular track directly without using a browser.
To install themes, go to the bottom tab "Sound" or "Ringtones." This is a catalog of audio, often broken down by genre. If you choose the right option, click "Download" or "Apply." Once you use the track, it will automatically stand on the current active SIM card or be offered for selection. An important nuance: the application of themes may require a sign-in to a Mi Account and a region other than the Russian Federation (for example, India or Indonesia) for full access to the store.
If you feel limited, third-party apps from the Google Play Store come to your rescue, programs like Ringdroid or MP3 Cutter allow you to not only edit the audio, but also assign it to the contact immediately, they have direct access to the phone book and can assign tunes without the standard interface restrictions.
| Method of installation | Difficulty | Flexibility of setting | Dependence on the MIUI version |
|---|---|---|---|
| Through contact settings | Low. | Tall. | No. |
| Through global settings | Low. | Medium (general only) | No. |
| Annex “Themes” | Medium | Medium | High (depending on the region) |
| Third-party utilities | Medium | Maximum | No. |
Using third-party software has the advantage of a more user-friendly cropping and destination interface, but be careful with the permissions you give to these applications. Access to contacts and storage is sensitive data, and only trusted developers with a good reputation should trust it.
Problem Solving: When a Melody is Not Set
Often, users are faced with a situation where everything seems to be done correctly, but Xiaomi does not set the tune to the SIM or is a standard one. One of the most common reasons is the caching of the Contacts or Phone application data, the system can "remember" the old setting and not apply the new one, in which case cleaning the cache helps.
To do this, go to Settings → Applications → All apps. Find Contacts and Phone in the list. Click on each and select Clear → Clear Cache. Attention: Don't confuse it with Clear All Data, as this may result in deleting your call history or display settings, even though the contacts themselves are usually synchronized with the cloud.
⚠️ Warning: If the cache is cleaned, check the Files or Music app's access to the storage. Without permission to read the internal memory, the system will not be able to read the new audio file.
Another reason is the length of the path to the file, and some versions of Android have limitations on folder nesting or Cyrillic characters in the path name, and try to move the audio file to the root of the Ringtones folder and call it Latin, and make sure that the file is not corrupted and playable in any other media player.
Features of work in the mode "Do not disturb"
Special attention should be paid to the interaction of individual tunes with the Do Not Disturb mode, which is the settings of this mode in MIUI and HyperOS, which have the function of "Repeat Calls" and "Favorites." If you add a contact to the exceptions of the "Do Not Disturb" mode, it can break through the silence, but the sound can be replaced with standard or vibration, depending on the priority settings.
To make a customized tune work properly, even in strict energy saving or silence modes, you need to manually adjust the exceptions. Go to the Do Not Disturb mode settings and select the add contacts option. Here you can specify that calls from certain individuals (who have already been assigned your special ringtones) should ignore the silence mode.
This is especially useful for highlighting important communication lines, for example, calls from a working SIM card can be completely silenced after 18:00, unless the boss calls, whose contact is added in exceptions, in which case you hear the exact tune that was assigned to him, which will allow you to instantly respond to an important call.
