How to Set Different Melodies on Xiaomi SIM-map

Smartphone personalization is not just a matter of aesthetics, but also an important element of ergonomics of device use. When a phone rings, it is vital that the user instantly understands which number is being called to make an informed decision about the response. Owners of Xiaomi, Redmi and Poco devices often face the need to separate audio signals, especially if one number is used for work and the second for personal contacts. Standard settings of the MIUI system or the new HyperOS allow flexible management of audio, but the algorithm of actions is not always obvious at first glance.

The Chinese manufacturer's modern Android shells provide a wide range of tools for fine-tuning multimedia. You can assign a unique composition not only for each contact from the phone book, but also divide incoming calls across the phone. SIM-This is especially true in regions where the practice of using two telecom operators at the same time is popular. Unlike many other brands, Xiaomi allows you to assign tunes to the user. SIM-cards even without using third-party launchers or root rights, using a staff file manager and sound settings.

In this guide, we will take a closer look at the nuances of the process, look at possible errors, and offer solutions for different versions of the firmware. We will discuss format compatibility, system ringtones, and how the system behaves when updated. Understanding these mechanisms will help you create a truly user-friendly sound environment where every call is recognized in a fraction of a second.

Preparation of audio files and format verification

Before you start setting up your system, you need to make sure that your audio files are technically compatible with the Android operating system. Xiaomi smartphones by default support popular formats such as MP3, M4A, WAV and OGG. However, for system ringtones that will appear in the call selection menu, there are certain requirements for the location of files in the device’s memory. If you downloaded music from the Internet, it is most likely in the Download or Music folder, but the system may not see it in the list of available ringtones without proper placement.

For the correct operation of the function of dividing melodies into two SIM-Cards, audio files should be stored in the device’s internal memory, not on the memory card. SD, if it is used, although the current version MIUI External drives are also often readable, and it is recommended to create a separate folder called Ringtones at the root of internal memory or in a folder. MIUI, Automatically index tracks as potential call signals.

Pay attention to the length and bitrate of the track. Too long tracks can be cut by the system or play incorrectly at the time of incoming call. The optimal ringtone duration is 15 to 30 seconds. If the file has a non-standard bitrate or is encoded in a rare format, the system may ignore it when trying to install.

Basic setting through the system sound menu

The main way to manage audio signals is through the standard settings menu. The algorithm of actions may vary slightly depending on the version of the shell, but the logic remains the same for all Xiaomi devices. You need to open the Settings app and find the section responsible for the sound, which is usually called Sound and Vibration.

Inside this section, you'll see Ringtone or Call Melody, and clicking on it will open a list of preset songs and files that the system has found in memory. SIM-maps: at the top of the screen or in the drop-down menu are often located tabs or switches marked as SIM 1 and SIM 2 (or operator names, for example, MTS Beeline).

If you don't see the SIM split right away, look for the context menu or additional settings within the tune list. In some versions of HyperOS, you must first select the SIM card itself in the global communication settings to activate customization. After switching to the desired card, simply select the desired track from the list. The system will automatically remember the choice for the specific slot.

Use of the "Themes" application to expand the library

The standard set of tunes may seem limited, and here comes the Xiaomi Themes system app, which is not just a catalog of wallpapers and icons, but also a powerful tool for managing audio content. In the Ringtones section of the Themes app, you can find thousands of free and paid songs that are optimized for working with the MIUI shell.

The advantage of using this method is that you automatically integrate the downloaded track into the system. You don't have to manually move files through folders or convert them. Once you download the melody from the directory, it immediately becomes available for assignment to any of the following files. SIM-cards through the standard menu of sound settings.

The Themes app also allows you to create your own ringtones from the music you store in your phone's memory, so you can pick any song you want by cropping it right in the app interface, which is especially useful if you want to put a specific track clip on your second SIM card that will signal calls from colleagues or delivery services.

💡

Use genre search in the Themes app to quickly find the right music. Pop, Rock or Classic filters will save time if you are looking for a specific mood for different contacts.

Configure via the application "Contacts" and "Phone"

There's an alternative, but equally effective way to manage your tunes, which allows you to set your settings in more detail, not just by the SIM card, but by the call type, and you can use the Contacts app or the standard Caller. Open any contact in your phone book.

In the contact card, find the Rington field. When you click on it, you'll see the choice of melody. In modern firmware versions, when you select the ringtone for the contact, the system can suggest that you specify which ringtone to use. SIM-This rule applies if the contact is not tied rigidly to one number, but a more reliable method is to customize (default) tunes for each number. SIM call-message.

Open the Phone app and go to settings (usually three dots in the corner or a gear icon). Find the Incoming Calls section. There is often a Call Melody option where you can customize signals for SIM 1 and SIM 2 separately. This method is good because it works at the incoming call processing level, which ensures that the correct sound is triggered even if the system settings of the sound were knocked.

For the convenience of choosing the best personalization method, let’s compare the basic methods on key parameters, which will help you to understand which option is best suited to your tasks and level of technical training.

As the table shows, Xiaomi’s standard tools cover the needs of the average user.The use of third-party launchers for this purpose is often excessive and can lead to unstable interface performance.

Possible problems and solutions

Despite the system's fine-tuning, users may encounter situations where a set tune is not played or reset to a standard one. One of the common reasons is access rights. Once the system is upgraded, the application responsible for the sound or theme may lose permission to read the internal memory.

⚠️ Note: If after updating the firmware melodies are missing, check the permissions in the App section → All applications → Themes (or Sound) → Permits: Make sure that file and media access is allowed.

Another common problem is the file format: If you copied a track from a computer, it may have metadata or encoding that Android doesn't recognize as a valid ringtone. Try renaming the file by removing special characters from the title, or saving it back to MP3 format at 128 kbps bitrate.

If you have "Do Not Disturb" or "Silent Mode" on, the ringtone may not sound, regardless of the settings. SIM-Check the side switch or sleep schedule settings to rule out software-based sound blocking.

💡

In 90% of cases, the problem with the lack of sound is solved by checking the physical switch silent mode or restarting the device after installing a new melody.
