Why Tone Mode Is Important for Xiaomi Calls
Tonal Mode (DTMF) is a technology that converts keystrokes on a phoneβs keyboard into audio signals. Without it, you canβt interact with automated systems of banks, support services or voice menus. On Xiaomi smartphones with MIUI firmware, this mode can be disabled or malfunctioned by default β especially after updates or resets.
Complicating the problem, new versions of MIUI 14/15 have changed the path to tone settings, and some models (such as the Redmi Note 12 or POCO X5) have hidden the option deep in the menu.This article will help you understand how to turn on the tone mode on any Xiaomi smartphone β from the budget Redmi to the flagship Xiaomi 13.
We will look at three methods: through standard settings, with the help of USSD-We'll also look at some common errors that can cause the tone to go down even if it's on.
Method 1: Enabling tone mode through MIUI settings
The most reliable and versatile method is activation via the phoneβs settings menu, which works on all Xiaomi models, including the Redmi 10/11, POCO F4/F5 and Xiaomi 12T. The main thing is to know the exact path, since the location of the item may differ in different versions of MIUI.
Instructions:
- Open the phone application (pipe icon).
- Click on the three dots in the top right corner and select Settings.
- Go to the Additional Settings section (or System settings on some models).
- Find Tonal Mode (may be called DTMF or Dialing Sounds).
- Activate the switch to the position on..
If Tonal Mode is not on the menu, your firmware is using an alternative path.
- π± Settings β SIM-maps and mobile networks β Settings SIM-map β Tonal regimen
- π§ Settings β Annexes β Application management β Phone. β Permits β Additional settings
The "Tonal Mode" item is activated in the settings
The sound of the number set is heard when the call is made
Automatic systems recognize the entered numbers
No errors in recruitment USSD-query (*100#, *111#, etc.)
-->
Some devices (such as the Redmi Note 10 Pro) require a phone restart after the tone is turned on. If the dial sound still doesn't work, move on to the next method.
Method 2: Activation through USSD-codes (for experienced users)
If the standard settings do not help, you can turn on the tone mode with the help of special USSD-This method is suitable for devices with custom firmware or if the menu MIUI damaged.
You will need the following codes:
- π ##4636## - Opens the engineering menu (not working on all models).
- π’ ##8667## - Keyboard test (checks tone signals are sent).
- π ##4636## - Alternate code for some versions MIUI.
How to use:
- Open the Phone app and enter one of the codes above.
- If you see a Testing or Service Mode menu, select Phone Information.
- Scroll down and find the DTMF Tone (or Tone Generation) item.
- Set the Enabled value.
What to do if USSD-codes don't work?
β οΈ Warning: Do not change other options in the engineering menu unless you are sure of their purpose.
After activation of the tonal mode through USSD Check it by calling a short bank number (e.g. *100#). If the signals don't pass, the problem may be in the system. SIM-map or operator settings.
Method 3: Using Third-Party Applications
If none of the previous methods worked, you can use third-party apps from Google Play, which emulate tonal mode and often save on devices with non-standard firmware.
Top.-3 tested applications:
| Annex | Features | Compatibility |
|---|---|---|
| DTMF Tone Generator | Generates tonal signals manually, supports sequence recording | All Xiaomi models on Android 9+ |
| True Phone Dialer | Replaces the standard phone application, has a built-in tone mode | Requires permission to call. |
| Zoiper IAX SIP VoIP | For IP-telephone, supports DTMF through SIP-protocol | Good for business users |
How to set up:
- Install one of the applications (e.g. DTMF Tone Generator).
- Open it and allow access to the microphone and calls.
- In the settings menu, look for the option Enable DTMF or Tone Mode.
- Select the signal type: In-band (standard) or SIP INFO (voIP).
β οΈ Note: Some applications may conflict with a standard call MIUI. After installation, check if the sound is lost during normal calls.
If you use Xiaomi with two SIM-With cards, make sure that the tone is on for the line you're calling. SIM separately.
Typical problems and their solutions
Even after the tone mode is turned on, Xiaomi users are faced with errors, and here are the most common ones and ways to fix them:
- π No sound when dialing: Check the volume in the call (adjusted by volume buttons during the conversation). Make sure that the Quiet dial mode is not activated in the phone settings.
- π΅ Automatic systems don't recognize signals: Try typing numbers slower - some banking systems require delays in the process 1-2 Use an alternative method of dialing: instead of holding a number, press it several times in a row.
- π Tonal mode resets after reboot: Update firmware to latest version MIUI. Reset network settings: Settings β SIM-maps and mobile networks β Resetting network settings.
The sound doesn't work when dialing.
Automatic systems do not recognize signals
Mode resets after rebooting
Another problem.

On devices with MIUI 14 and later, sometimes resetting the settings of the Phone application helps:
- Go to Settings β Applications β Application Management.
- Find the phone and press Warehouse.
- Select Data Reset (application settings will reset, but contacts will be saved).
In some models POCO (for example, POCO X3 NFC) The default tonal mode only works for the first SIM-To activate it for the second. SIM, You need to manually change the settings in the engineering menu.
Checking the tone mode
After setting the tone, it's important to make sure it works correctly.
- Call a short bank number (e.g. *100# or *111#).
- Listen carefully to whether the sound signals are heard when you press the numbers.
- If the system responds with a voice or SMS, then the tone mode is working.
For a more accurate check:
- π± Use the app. DTMF Decoder (available on Play Market) shows what signals your phone is sending.
- π§ Connect the headphones and check if the tonal sounds are heard through them (sometimes a problem with the phone's speaker).
- π‘ Call from another phone and ask the person to confirm if they hear signals when dialing.
π‘
If you frequently call automated services, keep the frequently used services USSD-For example, create a contact "MTS Balance" with the number *100#. This will save time.
If the tone mode is still not working, the problem may be on the operator's side. Contact your mobile provider's support team and check if they are blocked. DTMF-signal SIM-map.
Features on different models Xiaomi
Depending on the Xiaomi model and the MIUI version, the process of enabling the tone mode may differ. Here is a brief overview for popular devices:
| Model | MIUI version | Features of the tonal regime |
|---|---|---|
| Redmi Note 10/11 | 12β14 | Tonal mode is enabled via Phone Settings β Additional. Some firmware requires a reboot. |
