How to set different tunes on SIM-Xiaomi maps: detailed guide

Modern smartphones Xiaomi and Redmi have long switched to the standard of two SIM-But the standard audio setting often boils down to one common ringtone that rings the same for all incoming contacts, creating confusion. You can’t tell who’s calling right away – a boss on a work SIM or a friend on a personal one – until you look at the screen.

Fortunately, the MIUI shell and the new HyperOS provide built-in tools to fine-tune audio profiles.You don’t need to download third-party apps or obtain root rights to make the call sound unique to each SIM card. In this article, we’ll take a look at all the nuances, including hidden notification settings and frequent file selection errors.

It's worth noting that the menu interface may vary slightly depending on the Android version and regional firmware. Global versions often differ from Chinese versions, but the logic of the system remains the same, the main thing is to carefully follow the steps to avoid a situation where the melody is installed on the wrong map.

Preparation of audio files and system requirements

Before you start setting up, make sure the audio files themselves are ready to use. Xiaomi's system supports popular formats such as MP3, M4A and WAV. However, to properly display in the list of ringtones, the files must be in the correct memory partition.

If you downloaded a tune from the Internet, it is most likely in the Download or Music folder. For convenience, it is recommended to move the desired tracks to the Ringtones root folder or create subfolders there for each SIM card, for example, for example, SIM1_Work and SIM2_Personal. This is not a strict requirement, but it will greatly speed up the search for the desired file in a long list of system sounds.

Pay attention to the length of the track. Too long tracks can be cut by the system or not work properly in vibration mode. The optimal ringtone duration is 15 to 30 seconds. DRM-the system, otherwise the system will not be able to reproduce it.

• 🎵 Check the file format: best to use MP3 bitrate at least 128 kbit/s.
• 📂 Place files in the Ringtones folder for quick access through standard Explorer.
• 🔊 Test the sound in advance: make sure the file is played without wheezing and stuttering.
• 📱 Make sure both of you SIM-Cards are active and defined by the system.

⚠️ Note: If you use cloud tunes (e.g. from Mi Music), make sure the file is fully uploaded to the device, not just displayed as a link.

Set up individual ringtones for incoming calls

This is the main section that most users are interested in, and to assign different tunes, you need to go to the audio settings menu. The path may vary, but most often it is at Settings → Sound and Vibration. In some versions of the firmware, this item may be simply called "Sound."

Inside the menu, you'll see a section called "Rington" or "Call Melody," and clicking on it, the system will suggest you select a SIM card if there are two on the phone. This is the key point: you'll need to select SIM 1, find the track you want on the list and confirm the selection. Then the procedure is repeated for SIM 2.

If you don't see the maps split right away, try clicking on the current melody name. The list that opens up on top often has a switch or drop-down menu to choose which card the audio is being tuned for. In newer versions of HyperOS, this interface has become more intuitive and resembles a standard caller.

💡

Use short but recognizable songs for different SIM cards, like a hard signal for work, and a favorite tune for a personal card, and you can identify the caller without even taking the phone out of your pocket.

Remember, for each card, you can choose not only the music, but also the standard system sounds that are already embedded in the shell, which are optimized in volume and frequency to be clearly audible even in a noisy room.

Separation of notification and SMS sounds by SIM cards

Many people forget that different SIM cards can be assigned not only the sounds of a call, but also notifications, especially for those who use one card for registration in banks and services, and the second for communication, different sounds will help to instantly respond to important SMS without being distracted by spam.

The settings are done in the same Settings → Sound and vibration menu, but you need to look for “Notification Sound” or “Notifications.” As with ringtones, the system will ask which SIM card you want to change the sound for. Select the desired card and specify the preferred audio file.

You need to distinguish between application system notifications and SMS. For SMS, the setting is tied to the SIM card via the Messages system application. Go to the message settings, find the Notifications item and select the sound there. In some versions of MIUI, this option is also duplicated in the general audio settings.

Using Contacts for Unique Melodies

The most flexible way to personalize is to assign tunes to specific contacts, which works on top of the SIM card settings, so even if there's a common boring horn on SIM 1, you can set a unique song for an important contact that will redefine the system setting.

To do this, open the Contacts or Phone app, find the right subscriber and click on their name. In the card that opens, select Change (usually a pencil icon) and scroll down to the Melody or Rington field.

Here you can select the sound from the list. Importantly, if the contact is saved on a SIM card, rather than in a Google account or phone memory, the customization options may be limited, and it is recommended to store the contacts in the cloud for full access to MIUI features.

• 👤 Open the contact card in the phone book.
• ✏️ Press the edit button (pencil).
• 🎵 Find the Melody field and select a unique sound.
• 💾 Save the changes by clicking the tick.

⚠️ Note: When synchronizing contacts with Google, some custom ringtone settings may reset if there is conflicting data in your account.

Problems with displaying and playing files

Often, users are faced with a situation where the selected file does not appear in the list of available ringtones, which may be due to the permissions of the Settings application to the file system. In Android 11 and above, file access rights have become more stringent.

Try moving the audio file from the download folder to the Ringtones system folder through the file manager. If that doesn't work, check if the file is hidden. Files starting from a dot (e.g.,.secret.mp3) are considered hidden and don't appear in standard media selection lists.

Another common problem is a broken file. If a tune is not fully downloaded or corrupted during conversion, Xiaomi's system may ignore it when scanning the media library. Try opening it in any music player. If it's not playing there, it won't work as a ringtone.

💡

Files must be in the system-accessible folders (Ringtones, Music, Notifications) and not hidden to appear in the list of tunes.

In rare cases, cleaning up the media cache helps. Go to Settings → Apps → All apps, search for Media Storage or Media Storage and clear the cache. Once you restart, the phone will scan the memory again and find new tunes.

Customize volume and modes for different SIM cards

Set different tunes is only half the battle. It's important to adjust the behavior of the phone when you call. Xiaomi has a handy "Pocket Mode" feature and smart volume, but they work globally. However, you can adjust the vibration separately for each SIM card.

In the Sound and Vibration menu, find the "Ring Vibration" option, and you can also select a profile for SIM 1 and SIM 2 independently, so you can make one card only vibrate in silence and the other card make sound, which is useful in theater modes or meetings.

Don't forget to do "Do Not Disturb" mode, which allows you to create exceptions in its settings, such as allowing SIM 2 (personal) calls at night while SIM 1 (working) is silent. This is done through Settings → Sound and vibration → Do not disturb → Exceptions.

• 🌙 Set up a Do Not Disturb schedule to automatically turn on at night.
• 🔊 Use volume sliders to separate media and calls.
• 📳 Check the vibration patterns: they can also be unique to each card.
• 🔇 Make sure that the silent physical switch (if any) does not block the sound.
