How to Set Different Melodies on Different Sims on Xiaomi

Possession of a smartphone with two active SIM-Cards are the standard for many users, especially when you need to separate work and personal contacts or use tariffs of different operators to save money. MIUI HyperOS often leads to confusion: both numbers are calling with the same tune, and you can’t tell which phone or carrier is trying to contact you until you look at the screen.

Fortunately, Xiaomi engineers have provided a feature that allows you to assign unique audio tracks for each of the SIM cards, which greatly simplifies navigation in incoming calls. In this article, we will discuss in detail the algorithm of actions that will allow you to personalize the sound for SIM 1 and SIM 2, and also consider the possible nuances that arise when using different versions of the firmware.

Before you start setting up, make sure that the audio files you need are already uploaded to your device’s memory, which could be standard ringtones from your system library or your own MP3 or M4A tracks that you downloaded from the internet or transferred from your computer.

Preparation of audio files and system requirements

To make it work, it's critical that the music is physically present in the storage of your smartphone. System sounds are usually already built in, but if you want to put your favorite track, you have to put it in the right directory beforehand, most often the Ringtones folder in the internal storage, although modern versions of MIUI can find files in the Music or Downloads folder.

Note that the file format must be compatible with the system's media player. The most versatile and supported format is MP3 with a bitrate of at least 128 kbps to ensure acceptable speaker sound quality. If the file is corrupted or has a non-standard codec, the system can ignore it when choosing it as a call.

⚠️ Note: Do not use protected audio files DRM (downloaded from closed streaming services, as the system will not be able to reproduce them as a system ringtone without authorization in the source application.

Check if both SIM cards are active in the device settings.The melody selection menu for the second SIM card may be hidden or inactive if the slot is SIM 2 is software disabled or no physical module is inserted. Go to Settings → SIM-Maps and mobile networks to make sure both profiles are active.

Basic settings through the main sound menu

The most direct and reliable way to assign different tunes is to use the system menu of audio settings. This method works on most current Xiaomi, Redmi and Poco models. You need to open the Settings app and find the section responsible for the soundtrack. Depending on the firmware version, it can be called simply Sound and vibration or be entered in the Sound subsection.

Once you log in, you'll see a list of all system events that you can set up your audio response for. We're interested in Ringtone or Call Melody. Unlike the older versions of Android, where the settings were shared, MIUI often opens a dialog box or an additional screen to select which SIM card you want to change your settings for.

If you don't automatically split, and you only see one track list, look at the top of the screen, and you can have SIM 1 and SIM 2 tabs. Switch between them, you independently adjust the sound for each number, select the track you want from the list, and confirm the action with the OK button or Apply.

• 🎵 Open the settings and go to the sound control section.
• 📱 Select the setting of the incoming call ringtone.
• 🔀 Make sure the right one is selected. SIM-card (inlay 1 or 2).
• ✅ Confirm the choice of melody for the application of changes.

💡

If you don’t see the SIM card switching tabs in the audio menu, try changing the ringtone first through the Phone app, this method often duplicates the system settings.

Setting up ringtones through the phone app

An alternative and often faster path to the desired result is through a standard call app, which is particularly convenient because the interface is directly related to call management. Open the Phone app (green handset) and find the menu icon, which is usually represented by three dots in the upper right or lower corner of the screen.

In the drop-down list, select Settings. Next, you're interested in Incoming Calls. This is where you can get the subtle settings for how your smartphone behaves when you receive a call. In this menu, you'll see a clear split into two SIM cards if they're active.

Click on the option corresponding to SIM 1 or SIM 2. The system will prompt you to choose the source of the sound: standard Xiaomi tunes, Google sounds or files from the device memory. By selecting Files or Device Memory, you can specify any previously downloaded track. This method ensures that the setting applies to the selected communication profile.

It's worth noting that some global firmware versions may have slightly different paths, for example, when you enter the call settings, you may need to click on Rington Selection, and then the SIM selection menu will open.

Individual Melodies for Specific Contacts

Often, users don't just need to share calls by SIM card, but assign unique sounds to important subscribers to recognize them without looking at the screen. On Xiaomi smartphones, this is done through the Contacts app. Find the right person in the phone book and open their card.

At the top of the screen or in the menu (three dots), find the option to Set the ringtone. The system will suggest choosing which SIM card this rule will apply to. This is an extremely useful feature: you can set up calls from your boss to your work SIM will be accompanied by a strict horn, and calls from family to your personal one - a fun tune, ignoring the general settings of the SIM card.

It is important to understand the hierarchy of settings: the individual contact melody always overlaps the settings of the SIM card. If you set a unique sound for your mom in the contacts, even if you change the common ringtone for SIM 2, the previously specified track will play for her calls.

Use of third-party applications for advanced users

In cases where the standard MIUI functionality is not working properly or the interface is heavily modified by the manufacturer, specialized applications from Google Play come to the rescue. Programs like Ringtone Maker or Super Sound allow deep customization of audio files and system assignments.

However, when installing such applications, you need to be careful with permissions. They will need access to Contacts, Phone and Memory to work. Without these permissions, the application will not be able to “slip” the system to play the desired file when you call. In modern versions of Android (11 and above), access to the file system is limited, so the application can ask you to open a special folder through the system file manager.

⚠️ Warning: Avoid applications with dubious reputations that require excessive access rights, such as access to the Internet. SMS geolocation, as they absolutely do not need these functions to install the ringtone.

Using third-party software is justified if you want to create a complex scheme: for example, different tunes for different time intervals or days of the week for the same SIM card, which is difficult to implement with standard means.

Typical problems and ways to solve them

Despite the ease of setting, users often face a situation where the settings set do not apply or are reset.One common reason is the Do Not Disturb mode enabled.** In this mode, the system ignores user ringtones and can use silence or a standard silent signal, regardless of which SIM card is ringing.

Another common problem is the conflict of file formats. if you downloaded a track in high resolution (for example, FLAC) or with a non-standard sampling rate, the phone may simply skip it when trying to install, leaving a standard tune. MP3 usually solves the problem.

• 🔇 Check if the silent mode or meeting mode is activated.
• 📂 Make sure the file is in an accessible folder, not in a hidden application directory.
• 🔄 Restart the device after installing new ringtones to update the media cache.
• 🔋 Energy saving mode sometimes limits the background operation of the audio engine.

💡

The most common reason for the failure of settings is the incompatibility of the audio file format or its location in a secure folder, where the system caller does not have access.

It's also worth checking if there's a theme installed that forcefully changes the system sounds. Some custom themes in the MIUI Themes store can block manual ringtones setting by imposing the theme author's audio row, which can help to return to the standard Classic or Default theme.

Conclusion and additional recommendations

Customizing different tunes to different SIM cards is not just a matter of aesthetics, but an important element of smartphone ergonomics, which allows you to instantly identify the source of the call without being distracted by screen checks, which is especially important during meetings or work.

It is recommended to periodically check the relevance of settings after major updates to the Android or MIUI system, as developers can change the logic of the audio subsystem.

Remember that personalizing your device improves the comfort of your device, and don’t be afraid to experiment with different sounds to find the perfect balance between the visibility of a call and not being annoyed by loud or sharp signals.
