How to Set Different Melodies on Two SIM-maps on Xiaomi MIUI 12: Complete guide

Why can’t Xiaomi assign different tunes through standard settings?

Xiaomi smartphone owners with two SIM-The system is often inconvenient: MIUI 12, by default, only offers one ringtone for all incoming calls, regardless of number, which creates confusion, especially if you use one card for work and the other for personal contacts. → Sounds and vibrations are not a direct option for linking melodies to specific melodies. SIM.

The reason is because of the MIUI architecture: Xiaomi's developers initially focused on unifying audio notifications to simplify the interface, but this solution ignores the needs of users with multiple numbers. Fortunately, there are two ways to get around the restriction: through hidden system settings or through third-party applications. Next, we'll discuss both methods, from simple to complex.

It's important to understand that the functionality may vary depending on the smartphone model and firmware version. For example, the Redmi Note 10 Pro with MIUI 12.5 algorithm is slightly different than the Mi 11 Lite with MIUI 12.0.3.

Method 1: Configure with standard parameters (without root)

While there is no direct option, MIUI 12 has a hidden path for assigning different tunes, which works on most Xiaomi, Redmi and POCO models without having to get root permissions.

• 📱 Smartphone on the base MIUI 12/12.5 (Check in the settings → The phone)
• 🎵 Pre-loaded tunes in format.mp3 or.m4a (Place them in the Ringtones folder on the internal drive)
• 🔧 5-10 minutes of free time

Algorithm of action:

1. Open the Contacts app (an icon with a person’s silhouette).
2. Choose the contact you want to assign a unique tune to (such as a work colleague).
3. Click on three dots in the upper right corner → Edit.
4. Scroll down to the Melody of the Call (or Notification Sound for SMS).
5. Select the audio file you want from the list. If your tune is not available, click Add and specify the path to the file.
6. Save the changes.

Now, when you call from this number, you play the tune you've chosen, but there's a caveat: you can only set up individual contacts, not the entire network. SIM-For full map separation, read the following method.

If your file is not in the tone list, move it to /storage/emulated/0/Ringtones/ and restart the phone.

Method 2: Use the Dual App to Separate Completely

If you want all calls to a second SIM to have a unique melody (regardless of the contact), you will need a workaround with the Dual App feature. This tool is originally designed to clone messengers, but it can be adapted for our purposes.

Instructions:

1. Go to Settings → Applications → Dual App.
2. Enable the feature for the Phone app (or Contacts if the first one is not listed).
3. After creating the clone, open it and assign a second one. SIM-Default card (Settings) → SIM-map → Choice SIM default).
4. Return to the main Phone app and select one tune in the sound settings, and another in the cloned one.

Now, call first. SIM And then you're going to have a melody from the main app, and then you're going to have a clone of the app, and this is the only method that allows you to split the sounds into different parts. SIM-maps globally, not individual contacts.

Compatibility table with Xiaomi models

Not all Xiaomi smartphones support the described methods equally, and the following is the compatibility table for popular models on MIUI 12/12.5:

If your model is not in the table, check for the Dual App function manually.

1. Open Settings → Applications → All applications.
2. Find the Dual App (or Cloning Apps) list.
3. If there is no item, your firmware does not support this method.

Frequent Mistakes and How to Avoid Them

When customizing different tunes, users often encounter typical problems, and here are the most common ones and how to solve them:

• 🔕 Melody doesn’t change after selection: Make sure the file is in the Ringtones folder and has a supported format (.mp3,.m4a,.Reset the device.
• 📱 Dual App does not display Phone: Update your firmware to the latest version or use an alternative launcher (e.g. Nova Launcher).
• 🔊 Sound interrupted or played late: Turn off power saving modes for Phone and Contacts apps → Battery → Optimizing the battery.
• 🔄 Settings reset after rebooting: This indicates an error in the Dual App. Try clearing the app cache in Settings → Annexes → Application management → Phone. → Clear the cache.

⚠️ Note: On some firmware (for example, MIUI 12 for the European region) Dual App can be blocked for system applications, in which case the only way out is to use third-party launchers or manually assign tunes for each contact.

2. Select Vibration when calling.
3. Click on Additional (or Configure in some firmware).
4. Enable the option of different vibrations for SIM-If you don’t have one, use the Dual App as in Method 2).
