How to Change Calls on Xiaomi: A Complete Guide to Setup in 2026

Xiaomi’s MIUI-based smartphones offer flexible settings for dealing with phone calls, from basic redirects to advanced spam filtering. However, many users have difficulty changing standard settings: some menus are hidden in the depths of the interface, and some features work differently than on stock Android. This article will help you understand all the nuances from changing the ringtone of the call to configuring conditional redirection to other numbers.

We analyzed the features of the latest versions of MIUI 14 and MIUI 15 (including global and Chinese builds), and also took into account the specifics of popular lines – Redmi Note 12, POCO X5, Xiaomi 13 and others. All instructions are adapted to the current realities of 2026: taking into account changes in the policies of operators (for example, restrictions on forwarding from MTS and Beeline) and new features like AI-filtering spam.

1. Basic call settings: melody, vibration, volume

To start with, the simplest thing is to change the sound and tactile signals. In MIUI, these options are scattered across two menus: Settings → Sound and Vibration and Phone → Call settings. It is important to understand that some options (such as adaptive volume) may not be available on budget models like the Redmi A2.

To change the ringtone:

• 🎵 Open the phone application → tap three points in the upper right corner → Settings → The ringing melody.
• 🔊 In the list, select the system melody or click Add to upload your file (formats are supported.mp3,.m4a,.wav to 5MB).
• 📱 In some models (for example, POCO F5) The way will be different: settings → Sound and vibration → The ringing melody.

The vibration is set separately. In the same Sound and Vibration menu, find the Vibration section and select one of the preset patterns or create your own. Note that linear motor devices (such as the Xiaomi 13 Pro) have additional effects like Rhythmic Vibration.

2 Call forwarding: how to set up a redirect

Call forwarding is useful when you need to temporarily redirect your incoming phone to another number, such as when traveling abroad or using a second phone. In MIUI, this option is hidden deeper than in Android stock, and it depends on the carrier.

Instructions for setting:

1. Open the phone application → ⋮ → Settings → Additional settings → Call forwarding.
2. Choose. SIM-map (if there are two) and type of forwarding: 📞 Always redirect - all incoming will go to the specified number. 🕒 If no response is available, it will work in 5–30 seconds (configured separately). 🚫 If not available – when the phone is turned off or out of coverage. 📵 If it’s busy, if you’re already talking.

Importantly, MTS, Beeline and Tele2 can block redirects to other networks or roaming, for example, MTS has a restriction on redirecting to numbers abroad without the connected option “World conversation”.

3. Blocking unwanted calls and spam

Steps to activate:

• 📱 Turn on the switch to Lock unknown numbers (will ignore calls from hidden numbers).
• 🔍 Activate Spam Filter and select the severity level: Medium – blocks only obvious spam (banks, collectors). High – can mistakenly block legitimate calls (for example, from delivery services).
• 📝 To add a number to the blacklist manually, tap on Add to the blacklist and select a contact or enter a number.

In the models with MIUI 15 (for example, Xiaomi 14) has a feature AI-Call analysis: the system recognizes the robot's voice and automatically resets spam calls to turn it on:

Settings → Applications → Permissions Management → Phone → Allow “Call Analysis”

💡

If an important call is spammed, check the Locked folder in the call log, which stores all the ignored numbers for the past 30 days.

• 📞 Call the first caller and wait for the answer.
• 🔄 Click Add Call (button appears on call screen) and dial the second number.
• 🔗 After answering, tap Join to create a conference (maximum 5 participants on most models).

⚠️ Attention: operators can charge for conferencing as separate outgoing calls, for example, MegaFon charges each member added.

5. Change of settings SIM-card (double) SIM)

If your Xiaomi supports two of your SIM-Cards (e.g. Redmi Note 12 Pro)+ or POCO X5 Pro, you can flexibly configure which one is used for default calls, and this is true if one card is for work and the other card is for personal calls.
