How to put different tunes on different SIMs in Xiaomi Redmi Note 7

Xiaomi smartphones, and in particular the popular Redmi Note 7 model, have long established themselves as devices that offer advanced functionality even in the budget segment. One of the key features of the MIUI shell is the deep customization of the user interface, including audio events. For owners of two SIM cards, it is critical to be able to distinguish incoming calls without having to look at the screen, which significantly improves the comfort of using the gadget in everyday life.

However, the standard procedure for installing ringtones often confuses users, since the default system suggests choosing a melody for all contacts or both lines at once. In this article, we will discuss in detail the algorithm of actions that will allow you to assign unique sound files for each of your SIM cards, you will learn about the hidden features of the settings menu and get answers to questions that arise when working with the Android file system.

Preparation of audio files and file system

Before you start setting up system audio settings, you need to make sure that the audio files themselves are properly prepared and placed in the device’s memory. Redmi Note 7 runs on the Android operating system, which has a strict directory structure, and placing files in unintended folders can lead to the system simply “not seeing” your tune in the list of available ones.

The best option is to use a built-in file manager or connect your smartphone to your computer. You need to copy desired audio tracks to the root folder Music or Ringtones in internal storage. The file format should be compatible with the system, the most universal and recommended standard is MP3 with a bit rate of at least 128 kbit / s to ensure high-quality sound through the speaker.

⚠️ Note: Do not use files with DRM-protection (for example, tracks from paid subscription streaming services), as the system will not be able to play them as a system call.

If you download music from the Internet, make sure the file does not have unnecessary characters in the title, which can cause encoding errors in older versions. MIUI. It is best to rename the tracks in Latin, for example, Sim1_Call.mp3 and Sim2_Call.mp3, to avoid confusion later on.

Setting up ringtones via the Sound and Vibration menu

The main way to manage audio profiles in Xiaomi is through system settings, which is the most reliable method, since it guarantees the application of settings at the system level, not just within a specific caller application. First, open the main menu and find the Settings icon, then go to the Sound and Vibration section.

In the menu that opens, you'll see Ringtone, which is usually set as one for all calls. To change that logic, you click on this item. In newer versions of the MIUI shell, which are relevant for the Redmi Note 7, the system often offers a choice of sound source: "All", "SIM 1" or "SIM 2."

💡

Use the pre-listen feature in the ringtone selection menu to make sure the file is played correctly and not cropped at the beginning or end.

Once you select the right SIM card, you'll see a standard file manager or system melodies list. Find the track you previously downloaded. If you can't see your file, use the Add button (often marked with a plus) to access the entire file system of the device. Select a file from the Music or Download folder.

Separation of settings through the Phone application

An alternative and sometimes more convenient way is to configure directly through the Phone app, which has advanced functionality in Xiaomi. Open the "call" and notice the three dots in the upper right corner of the screen opening the context menu. Select Settings.

In the call settings menu, find the Additional settings section or immediately go to the incoming call settings. SIM-The interface may vary slightly depending on the version. MIUI (Global or China, but the logic remains the same: you choose a particular SIM card and assign it an audio file.

The advantage of this method is that it often allows you to switch between profiles faster if you temporarily want to turn off the sound for only one of the SIMs.

Using Contacts for Individualization

You can even fine-tune it through your address book, and if you want to hear a specific tune not just for Simka 1, but for calls from certain people to that SIM, you can use the contact functionality to open the Contacts app, select the person you want to hear, and click Change.

Scroll down to Rington. Some versions of MIUI also have a choice of SIM card if the contact is tied to a particular line. However, even if there is no direct link, setting a unique ringtone on the contact will allow you to know who is calling, regardless of which SIM card was called.

For mass control, you'd better use a grouping, and you could create contact groups (e.g., Work, Family) and assign them different tunes, and you could create a complex but convenient sound pattern where you would know not only the line, but also the context of the call before you picked up the phone.

Solutions to reproduction problems

Redmi Note 7 users may find themselves resetting or not playing the tune after installation, often due to MIUI's energy-saving algorithms that can freeze background processes that control media audio. Check whether the restriction on the Themes or Sound app is worth it.

Another common problem is format mismatch. While MP3 is the standard, some variable bitrate (VBR) files can play with a delay or wheez. Convert such files to a constant bitrate (CBR) using computer converters.

⚠️ Warning: If after rebooting the phone the melody is reset to standard, try clearing the cache of the Themes app through the Apps menu» → «Application management».

As you can see from the table, Xiaomi’s standard tools provide sufficient tools for most use cases. It only makes sense to resort to third-party solutions in exceptional cases when standard functionality is damaged or trimmed by a particular firmware version.
