Xiaomi smartphone owners often face the need to personalize incoming calls, especially when using two SIM cards. Standard setting of the MIUI or HyperOS system allows you to flexibly manage audio notifications, but it is not always obvious how to assign a unique tune specifically for the first or second SIM card.
Unlike many other manufacturers, the shell interface MIUI It has its own characteristics in the distribution of media files. It shares the general sound settings and the specific parameters for each. SIM-Understanding this structure is essential to avoid getting confused in the menu and quickly adjust the device to suit your needs. Below we will discuss in detail the algorithm of actions that is relevant for most modern models of the brand.
Before you start setting up, make sure your audio files are uploaded to the device memory, the system will not be able to select a track if it is in the cloud or hidden in system folders, and preparing a media library is the first step to successfully customize calls.
⚠️ Warning: Make sure the audio file format is compatible with Android.The optimal choice is MP3 or AAC. Files in format.m4r (iOS standard may not be defined by the system without prior conversion.
Preparation of audio files and memory structures
To work properly, the files must be located in the memory partitions available for the system. In modern versions of Android, access to system folders is limited, so it is better to use standard directories or cloud services and then save them to local storage. If you download music from the Internet, by default it falls into the Download folder, which is suitable for further manipulation.
However, for ease of management, it is recommended to create a separate folder structure, which will help to avoid confusion between system sounds and your personal records. Ringtones_Custom This is especially true if you are using a file manager other than the standard Explorer.
- 📂 Create a folder with a clear name in the internal storage for your tunes.
- 🎵 Copy or move the desired tracks to the created directory.
- 📱 Make sure that files are not hidden and have correct tags (name, performer), as the system often sorts them by these parameters.
Too long compositions (more than 2-3 minutes) may be cut by the system or play incorrectly at the time of incoming call. The optimal duration of the ringtone is from 15 to 45 seconds.
💡
Use online services or cutting apps to cut the most recognizable snippet from a song, making the call less intrusive and more informative.
Basic settings through the Sound and Vibration menu
The main way to manage melodies is through system settings. The interface may vary slightly depending on the version of the shell, but the logic remains the same. You need to go to Settings, and then select Sound and Vibration, and that's where all the tools for managing the audio of the smartphone are concentrated.
In the menu that opens, you will see the Call Melody section, and clicking on it, the system will suggest selecting the source of the sound. By default, it displays standard Xiaomi tracks. To see your files, you need to click on the plus or + button in the upper corner of the screen (or the "Select a Melody from Files" button, depending on the version of MIUI).
Once you select a file from the list, it will become the primary ringtone for all incoming calls, but our task is to divide the threads for different SIM cards. In the same menu, just below or in the optional menu (three dots), often the settings for SIM 1 and SIM 2 are hidden. If you don't see the separation immediately, move to the next section, which describes the alternative method through the Themes app.
| Parameter | SIM 1 (Main) | SIM 2 (Worker) | General. |
|---|---|---|---|
| Priority of volume | High-pitched | Medium. | Depends on the script. |
| Type of melody | Personal. | Business | Standard. |
| Vibrosignal | Long. | Short. | By default. |
| Source of the file | Local. | Local. | Systemic |
Using the Topics app to split calls
If you do not find a clear separation in the standard audio settings menu SIM-Themes, a built-in tool by Xiaomi that is often ignored as a wallpaper shop, but it's much more functional than that. It allows you to customize your call profile deeply.
Open the Themes app and go to Profile (usually the person icon in the lower right corner). Here, select Call Melody. Unlike the audio settings, there is often a clear separation: SIM 1 ring melody and SIM 2 ring melody.
Once you select the right SIM card, you will be placed on the list of available tracks. Click on the music note icon or plus to download your file from your phone's memory. The system scans the media library and offers available audio files. Once selected, the track will automatically apply to the corresponding slot.
⚠️ Note: Themes app may require an internet connection for initial profile synchronization.Make sure the connection is stable to avoid errors while saving settings.
☑️ Checking the call settings
Setup through the Contacts and Phone app
There's another layer of personalization that overrides the overall settings, so you can assign unique music not just to the SIM card, but to a specific contact, so you know who's calling before you even look at the screen. If the contact is given its sound, it will play; if not, the melody set for the contact will play. SIM-map.
To set this up, open the Contacts app or Phone. Find the right subscriber in the list and open the contact card. At the bottom of the screen or in the menu (three dots), select the Select Rington option. Here you can also choose which SIM card this rule applies if the contact is tied to a specific number.
This feature is especially useful for important calls from an employer or close relatives. Even if the phone is lying down in the bag, you immediately understand the importance of calling by sound. The system allows you to use the same files as for general settings, so pre-preparation of the media library is also relevant here.
- 📞 Open the contact card in the phone book.
- 🎵 Click on "Set a ringtone" or "Melody".
- ✅ Select a track from the list and confirm the action for a specific SIM.
Note that in some versions of HyperOS, the interface can be slightly modified, and the settings of the ringtone can be hidden under the button "More" or edit contact. Carefully study all available menu items in the subscriber card.

Problem Solving: Why the Melody Doesn't Work
Sometimes users are faced with a situation where after installation, the music is not playing, and the standard squeak is heard. The most common reason is the access rights. The Themes or Settings application may be denied access to the device memory. Check this in Settings → Applications → All applications, find the desired application and make sure that permission to access files is active.
The second common problem is broken files or an unsupported codec. If a track has been downloaded from a questionable source, it can be damaged. Try playing it through any music player. If there is no sound or it is distorted, the file needs to be replaced. Also check if the Do Not Disturb or Silent Mode mode is on, which blocks ringtones playback.
In rare cases, cleaning the cache of system applications responsible for sound helps. Go to Settings → Apps → All Apps → Sound and Vibration (or similar system application) and select Clear Cache. This will not delete your files, but will reset temporary configuration errors.
⚠️ Warning: Do not remove the system applications of the sound engine completely, this can lead to a complete absence of sound in the system.
Features of work in the mode "Do not disturb"
Special attention should be paid to the interaction of user ringtones with Do Not Disturb mode. In this mode settings, you can create exceptions for favorite contacts. If you have set a unique tune for an important contact, but it does not pass through the Do Not Disturb filter, you can skip the call.
To set exceptions, go to Settings → Sound and Vibration → Do Not Disturb. You can allow calls from Favorites contacts or from repeat calls, which ensures that even with active silence, you will hear your own special sound if the setting allows interruption.
There's also a Pocket Mode feature that can jam the sound if the proximity sensor is closed, so make sure that the audio settings are set to the correct option, or turn it off if it interferes with hearing calls in your bag.
💡
Properly configuring exceptions in Do Not Disturb mode is more important than the melody itself if you want to be guaranteed to hear important calls in silence.
