Set up different tunes for two SIM-maps to Xiaomi 10

Modern smartphones like the flagship Xiaomi 10 allow you to effectively manage two SIM cards simultaneously, separating personal and work calls. However, standard settings often suggest using a single tune for all incoming calls, which creates confusion when the device lies down. To instantly understand which number a call is coming to, you need to fine-tune the audio notifications through the system menu or address book.

The process of personalizing ringtones in the shell of MIUI or the new HyperOS is based on the binding of audio files to specific contacts or SIM cards through hidden call settings. You do not need third-party applications, since the built-in functionality of the phone fully covers the needs for separation of audio signals.

In this guide, we will go into detail on the algorithm that will allow you to assign unique tunes to each SIM card, we will look at working with system separators, setting up contacts and using third-party call managers if standard methods do not work, which will provide maximum comfort and will allow you to avoid missing an important call from your boss or client.

Audio file preparation and formats

Before you start setting up, make sure that the necessary music compositions are stored in the memory of your Xiaomi 10.The system supports most popular formats, however, for stable operation, it is recommended to use files in MP3 or M4R. Files should be downloaded to internal memory, not to the SD memory card, to avoid delays when playing.

For ease of management, create a separate folder at the root of the file system, for example, calling it "Ringtones." Put there short excerpts of songs that you plan to use. The track should not be longer than 30-40 seconds, otherwise the call may be cropped or played incorrectly. Long songs should be edited beforehand.

💡

Use audio files with a bit rate of 128-320 kbps for better sound quality, but make sure that the file size is not too large to waste RAM when loading the call interface.

If you use files from messengers, first save them to the Downloads folder, and then move them to the created directory for ringtones. This will eliminate the situation when after cleaning the messenger cache, the melody disappears, and the phone returns to the standard horn. File structure organization is the key to stable operation of the multimedia part of the smartphone.

• 🎵 Download or create two different audio files for each SIM card.
• 📂 Create a Ringtones folder in the device’s internal memory.
• 📱 Move files to this folder for quick access to the system.
• 🔊 Check the playback of tracks through a standard player.

Configure through the system menu calls

The first and most obvious way is to use the phone's built-in settings. Open the Phone app and go to the settings menu by clicking on three dots or a gear. Find the Call Settings or Additional Settings section, where SIM card settings are usually hidden, and here you can see the list of cards installed and the settings for each card.

Some versions of MIUI firmware have a direct "Call Melody" switch for each SIM card separately. If you have one, just select it and specify the desired file from memory. However, often the system offers to select only one default melody for all SIM cards, which requires the use of alternative methods, which will be discussed below.

It's important to note that when you update the operating system, the location of these items may change. If you don't find the right switch, don't rush to reset the settings. Most likely, your version of the shell requires you to assign a tune through a contact or use the access codes to the extended menu. Check the firmware version in the About Phone section.

The method of separation through contacts (the most reliable)

The most universal way, which works on all versions of Xiaomi 10 without exception, is to assign a tune directly to the contact. The logic is simple: if you know that calls from your mom come to SIM-1 and from working on SIM-2, just write for your mom's contacts the melody "Family" and for colleagues - "Work".

To do this, open the Contacts app, select the right subscriber, and press the edit button (usually a pencil or three dots). In the menu, find Melody or Rington. The system will suggest selecting a track from the standard list or from your folder. By choosing a unique sound, you are guaranteed to hear it, regardless of which SIM card the call from that number comes.

This method takes time to sort contacts initially, but it provides maximum accuracy. You can create contact groups like SIM 1 and SIM 2 and assign them the appropriate sounds, which is especially true if you use one card only for important calls and the other for registrations and spam.

⚠️ Note: When syncing contacts with a Google account, the tune settings may reset. To keep personalization, back up contacts in.vcx format or use Xiaomi cloud storage, which stores extended contact fields.

Use of access codes and hidden menus

For advanced users, there is an opportunity to access the engineering menu or test modes through special devices. USSD-codes or commands in the Calls app. Enter code ##6484## (CIT), You get into the hardware testing menu, and although there's no direct ringtone settings, you can check the speakers to make sure that the sound is playing correctly on both SIM cards.

It may be more effective to use commands to reset your call settings if the system is “glutched” and prevents you from selecting a track. However, the main method of fine-tuning through hidden menus in new versions of Android is often blocked by the manufacturer for security reasons.

If standard tools don't allow you to separate tunes, you can try installing the Google Phone app from the Play Market, which has its own call management interface that sometimes ignores the system limitations of MIUI and allows you to more flexibly configure notifications. Once installed, be sure to assign it to the default app for calls.

• 🔢 Enter the code. CIT test-piece.
• 📞 Try replacing the standard “caller” with Google Dialer.
• 🔄 Reset the settings of the "Phone" application through the application menu.
• 🛡️ Check memory access rights for contact applications.

Table of compatibility of formats and settings

To avoid errors in file selection, check the supported settings table. Using unsupported codecs can cause you to hear a crackle or a standard squeak instead of music.

Addressing common problems

Often users are faced with a situation where after choosing a melody, it is not applied or reset to a standard one after rebooting. This may be due to the permissions of the Contacts or Phone application to the file system. Go to Settings → Applications → All applications, find Contacts and check permissions. Access to memory must be allowed.

Another problem is the design conflict, and some third-party themes for MIUI have their own sound profiles that override the system settings, so if you can't assign your ringtone, try temporarily switching to the standard Classic theme and checking the sound, which will help identify the software conflict.

⚠️ Note: Do not use files with DRM-protected (bought from secure music stores) because the system cannot play them as a system call.

If nothing works, clean the cache of the Themes and Sounds app. Accumulated errors in these system services can block the application of new settings. After cleaning the cache, try reassigning the melody through the contact menu.

💡

The most reliable way to make a phone ring in different ways is by tying unique ringtones to specific contacts rather than to SIM cards globally.
