How to install different tunes on two SIM- cards in Xiaomi Redmi Note 10S: a detailed guide

Owners of Xiaomi Redmi Note smartphones 10S two-way SIM-The problem with cards is that you can't tell the difference between the first call and the second SIM by sound, and by default, the system uses one tune for both numbers, which creates confusion, especially if you use one SIM for work and the other for personal calls. Luckily, in the firmware MIUI (including versions 12, 13 and 14) there are hidden settings that allow you to assign unique ringtones to each of the ringtones. SIM-In this article, we will discuss all working methods, from standard functions to workarounds for those who do not have an option on the menu.

Many users mistakenly believe that this task requires root rights or third-party applications. In fact, in most cases, it is enough to configure the built-in system settings correctly. The main thing is to know where to look: depending on the version of MIUI, the path to settings may differ. We tested all methods on the Redmi Note 10S with the latest updates and are ready to share the verified instructions.

If you've tried to find this option in the Sounds and Vibrations menu before, but you haven't, don't be surprised. In MIUI 14 for the Redmi Note 10S, the custom ringtones feature for the SIM is hidden in the "Additional Settings" sub-menus, and in some regional firmwares, it has to be activated through "Special Features." Below you'll find the exact paths for each version of the interface, as well as alternatives if the standard method didn't work.

Verification of the MIUI version and preparation of the smartphone

Before you start setting up, make sure your Redmi Note 10S It's based on the current firmware version, and it's not just the individual ringtone function that depends on it, it's also the stability of the device. To check the version MIUI:

Step 1. Open the settings → About the phone.

Step 2. Scroll down to the MIUI Version block. This will show the current firmware (e.g. MIUI Global 14.0.5).

Step 3. If the version is older than 12.5, we recommend updating through Settings → System Update. For the Redmi Note 10S, critical fixes come out regularly, and new builds often add hidden features.

Also check if both SIM- cards are active:

1. Go to Settings. → SIM-maps and mobile networks.
2. Make sure that both SIMs are on (sliders in the "On" position).
3. If one of the cards is disabled, activate it - otherwise the ringtone setting will not be available.

⚠️ Warning: Some firmware for China (CN) have individual ringtones blocked. If your Redmi Note 10S is purchased in China or is stitched with custom MIUI, you may need to change region to "Global" or "EEA" through Settings → Additional Region →

Method 1: Standard settings with "Sounds and Vibrations"

This is the simplest method that works on most devices with MIUI 12 and later.

Algorithm of action:

1. Open the Settings. → Sounds and vibrations.
2. Scroll down to the "Sound of a Call" section and tap it.
3. At the top of the screen, you’ll see two tabs with the names of your SIM- cards (e.g., “SIM 1” and “SIM 2”).
4. Click on the current tune (the default is “MIUI ringtone”) and select a new ringtone from the list or add your own through Local Melodies.
5. Repeat the steps 3-4 for the second SIM- card.
6. Go back to the main Sounds and Vibrations menu and check if the changes are still there (sometimes a reboot is required).

Download tunes in MP3 or M4A format (up to 5MB)

Place files in the Ringtones folder on the internal drive

Make sure that file names do not contain Cyrillic or special characters

Restart your phone before settings-->

If you don't have a tab with SIM- cards on the menu, then your version of MIUI doesn't directly support this function, in which case you go to the 2 Method or the 3 Method.

Where can I get my tunes?

• 🎵 Use built-in ringtones MIUI (about 20 of them).
• 📱 Download free tunes from Google Play Market (e.g., the Zedge app).
• 💻 Transfer your audio files to the /Internal Storage/Ringtones/ folder via a Explorer or PC.

⚠️ Warning: If you add your tunes, make sure they don't last more than 30 seconds. MIUI Cuts ringtones longer than that time, which can cause a sharp break in the sound during the call.

Method 2: "Special Opportunities" (for MIUI 13/14)

In the latest versions of the MIUI, developers have moved some settings to the "Special Features" section, which works even if there are no tabs for the SIM- cards in the "Sounds and Vibrations" menu.

Step-by-step:

1. Open the Settings. → Special facilities.
2. Scroll down and find the "Hearing" section (or "Sound" in some firmware).
3. Slip on the item SIM-cards Setting up sound (can be called Individual ringtones).
4. Select the first SIM- card and assign it a tune from the list.
5. Repeat the 4 step for the second SIM- card.
6. Save the changes and restart the phone (required!).

If there is no SIM-card Settings, try an alternative path:

1. In Special Options, activate the MIUI Optimization option (if disabled).
2. Return to Settings → Sounds and vibrations – tabs for SIM- cards should now appear.

💡

If the ringtones don’t change after setting up, clear the Settings cache through Settings → Apps → App Management → Settings → Storage → Clear the cache.
