Xiaomi Redmi Note smartphone owners often face the need to quickly identify which number an incoming call is coming to. In an era when the device is used to separate work and personal contacts, the ability to set different tunes on two SIM cards becomes not just a convenience, but a necessity. Standard MIUI settings allow you to flexibly manage audio notifications, but not all users know exactly where the desired switches are hiding.
The setup process can seem confusing due to the features of the HyperOS shell or earlier versions of MIUI. The system offers several levels of sound management: global settings for all calls, customization for each SIM card and personalization for specific contacts. Understanding this hierarchy will help you create a truly effective alert system that will not miss an important call from a boss or client.
In this guide, we will take a look at all the methods available, from basic ringtones setup in the system menu to fine-tuning through the contact menu, how to avoid common mistakes when the phone is silent or plays a standard horn instead of the composition you choose, and we will also touch on the topic of audio file formats and sources of their download.
Basic ringtone settings for each SIM card
The first thing you need to do is to set the common tunes for each of the SIM cards separately, which will set the "baseline" of the sound that will play if the caller is not added to your phone book or has no customization.
In the settings list, look for the Sound and Vibration section. This is where all the audio management tools of the device are concentrated. Unlike older versions of Android, modern shells group settings logically, but sometimes hide advanced options. You need to find Ringtone, which is usually located at the top of the screen.
Once you click on this, the system will tell you to choose which SIM card you want to change your settings for, and you will see the separation between SIM 1 and SIM 2. This is key: selecting a particular card allows you to assign a unique track to it, and if you skip this step and choose a non-tethered melody, it can only apply to one of the cards or become global.
- 🎵 Click on the speaker icon next to SIM card 1 to select the track for the first number.
- 📞 Repeat the procedure for SIM card 2 by selecting a contrasting melody for quick recognition.
- 🔊 Use the built-in player to listen to the fragment before use.
- ⚙️ Make sure the call volume slider is not in the minimum position.
⚠️ Note: Some system tunes may be blocked for change or missing if you use regional firmware (e.g., Chinese version without global language package.
After selecting the tracks, be sure to check the result by asking someone to call you on both numbers, to make sure the settings are applied correctly and the volume is adequate. If the sound is too quiet, go back to the Sound and Vibration menu and adjust the sliders.
Using your own audio files as a call
The standard set of tunes in Xiaomi is often boring and repetitive for many users. It is much more efficient to use your own recordings, songs or cut snippets of dialogue. To do this, your audio files must be stored in the memory of your smartphone. Most often they are downloaded through a browser or messengers and stored in the Download or Music folder.
For a file to be seen as a potential ringtone, it must be in a supported format. The most versatile is MP3, which is readable by all versions of Android and MIUI. OGG and WAV formats are also supported, but sometimes there are problems with assigning to a specific SIM card. If your tune doesn't appear in the list, try converting it.
The process of installing your file is almost identical to the system sound selection. Go to Settings → Sound and Vibration → Rington. Select the SIM card you want. In the melodies list that opens, scroll the screen to the bottom. There you will see the Add Melody or Plus icon +. When you click on it, you will be taken to the file manager.
☑️ Audio file verification before installation
In the file manager, find the folder where the track was saved. This is usually Internal storage → Download. Once you select the file, confirm the action. Now this track will appear in the list of available and will be marked as a user one. You can assign it to any of the SIM cards by following the algorithm from the previous section.
| Parameter | Systemic melody | User file | Online theme |
|---|---|---|---|
| Source | Built into the firmware | Memory of the device | Tham's shop |
| Formats | System-specific | MP3, OGG, WAV | Depends on the topic. |
| Flexibility | Low. | Tall. | Medium |
| Availability | Always. | File required | Internet is required |
Personalization of sound for individual contacts
SIM card tunes are only half the solution. It's often critical to hear a unique tune when a particular person calls, regardless of which SIM card the call comes to. In Xiaomi Redmi Note, this is implemented through the Contacts app or Phone.
Open a contact list and find the person you want to call. Click on their name to open their contact card. Be careful: in modern versions of MIUI, the audio settings may be hidden. Look for the Change button (usually a pencil) or three dots in the corner of the screen to call an additional menu.
In edit mode, scroll down to the Melody (or Rington) field. The default is the default. Click on it. The system will suggest you select a track. It's important to understand that if you choose a melody here, it will play when that person calls, even if the SIM card they're calling has a different common sound.
- 👤 Open the contact card in the Contacts app.
- ✏️ Press the edit button or action menu.
- 🎼 Find the Melody item and select a unique track.
- 💾 Save the changes by clicking the tick or OK button.
💡
If the contact has several numbers (mobile, work, home), the tune will apply to all numbers recorded in this contact card.
It's worth noting that the contact settings are always the priority, which means that even if the second SIM card has a quiet signal and the contact is a loud song, you'll hear the song. VIP-Persons, but may be confusing if you are trying to identify a SIM card from the sound.
Volume settings and "Do not disturb" modes
Even perfectly tuned tunes are useless if they are not audible. Xiaomi has a sophisticated volume control system that separates media, alarm clocks and notification sounds. Make sure that when you press volume buttons, you adjust the "Call" setting, not the multimedia setting.
Special attention should be paid to Do Not Disturb mode. You can create exceptions in this mode settings. For example, you can set your phone to keep it silent for everyone except your favorite contacts. To do this, go to Settings → Sound and vibration → Do not disturb.
You can schedule or activate manually here. It's critical to check the Exclusions section. If it allows calls from "Favorites" or "Recalls," the tunes for those groups will even sound silent, and this can create the illusion of a failure when the phone is ringing "on its own" at night.
⚠️ Attention: Pocket mode can block the sound of a call if the proximity sensor is contaminated or covered with a protective glass.
Also check if the silent mode is activated by physical buttons (if you have them on your model) or software switches in the notification curtain. Sometimes users accidentally switch the sound profile to Vibration, and the melodies stop playing.
Problem Solving: Why Melody Separation Doesn't Work
There are times when you think you're settings right, but Xiaomi Redmi Note keeps putting all the callers on the same tune, and most often the problem is the cache of the Phone or Contacts app. System processes could stick to the old settings.
Try clearing the cache. Go to Settings → Apps → All apps. Find a Phone (may be called Mi Dialer or just Phone) on the list. Click on it, select Storage and then Clear the cache. Don't confuse it with Clear Data, as this can delete your call history.
What if nothing has changed after cleaning the cache?
Another common reason is conflicting themes: If you installed a third-party theme from Themes, it can force the system sounds to change to its own, ignoring your SIM card settings. Try temporarily returning a standard Classic or Default theme and check the call's performance.
In rare cases, the problem may be with the melody file itself. If the file is corrupted, has a non-standard bitrate or (codec), the system may not be able to reproduce it and replace it with a standard horn. Try replacing the problem track with another, obviously working file.
Using third-party applications for advanced management
If standard MIUI capabilities aren't enough, the market offers applications that allow you to manage calls with greater flexibility, and programs like Ringtone Maker or Contacts Ringtones can automate the process of assigning tunes.
However, the use of third-party software on Xiaomi has its nuances: the system aggressively unloads the background processes to save battery. To make the application work correctly, you will need to issue it with extended permissions and prohibit energy saving for it. This is done in the App's menu. → Permits.
The most reliable way is to use the built-in functionality, as it is deeply integrated into the Android Telephony Framework. Third-party applications are more useful for editing audio (Fade-in/Fade-out) than for the purpose itself. Use them as a content preparation tool.
💡
The Xiaomi Redmi Note’s built-in tools fully cover the needs of 95% of users, and third-party apps are only needed for specific scenarios, such as randomization of tunes or complex schedules.
Remember that installing a large number of third-party services can slow down the call interface, and if you notice delays in answering a call, it is better to remove the support applications and return to the native settings.
