Do you still hear slow clicks instead of a quick dial? That means your Xiaomi is running in an outdated pulse mode — a technology that was used in analog PBX back in the 80s. Modern operators (MTS, Beeline, MegaFon, Tele2) have long switched to tonal dialing, but some smartphones default or after resetting their settings return to pulsed. As a result: calls do not go to hotlines, banks do not work, and autoinformers do not recognize button presses.
In this article, three proven ways to switch to tonal mode for all Xiaomi models (including Redmi and Poco) are available on the market. MIUI 12, 13 and 14. We'll take a look at the standard settings, the hidden engineering menu, and even manual input. USSD-No root rights or complicated manipulations, only official methods that work 99% of the time.
Why does Xiaomi phone use pulse mode?
The reasons for the automatic switch to pulse set lie in three factors:
- 📱 Outdated firmware MIUI (Especially important for Redmi budget models 9A/10A POCO M3, where the manufacturer saved on updates of the communication module).
- 📡 Problems with SIM-card: the operator forcibly transfers the device to pulse mode if the detect-tonal signal takes more than 3 seconds (often occurs when roaming or on old ones). SIM).
- ⚙️ Reset: After hard reset, the phone can “forget” network settings and return to factory settings, where the default is the pulse mode.
Interesting fact: in some regions of Russia (for example, the Far East or small towns), operators still maintain pulse dial for compatibility with old telephone stations, but even there, the tone mode is more stable - you just need to turn it on manually.
Yes, and it's not making any calls |Yes, but I didn't notice any problems |No, I'm in tone mode |I don't know how to check-->
Method 1: Switching through standard MIUI settings
The easiest method is to use the phone's built-in menu, which is suitable for 90% of users and does not require technical knowledge.
- Open the phone application (pipe icon).
- Click on the three dots in the top right corner and select Settings.
- Scroll down to the Call section and tap by Dial Type.

✅ Turn it off. VPN (It can interfere with the definition of the network)
✅ Turn the phone to "Only" mode. 4G" (mobile network settings)-->
⚠️ Note: On some firmware (for example, MIUI Global 13.0.4 for Redmi Note 11) after switching to the tone mode, the sound may disappear from the tube when outgoing calls. Solution: return to the call settings and turn on the voice amplifier option.
Method 2: Engineering menu (for hidden settings)
If the standard path didn’t work, use the engineering menu, which is universal for all Xiaomis, but requires caution — don’t change other settings to keep the network running.
Instructions:
- Open the Phone app and type the combination: ##4636## Some models (Poco X3 Pro, Redmi K40) may have an alternative code: ##36446337###
- You will be taken to the Testing menu. Select Phone Information (or Phone Information).
- Scroll down to the Set preferred network type section and make sure LTE/WCDMA/GSM auto is selected.
- Below, find the DTMF tone (or Tone dial) string and set the Enable value.
- Go back and restart the phone.
After rebooting, check dial mode: call any number with a voice menu (for example, *100# for Beeline or *111# for MTS) and press the number. If you hear a high tone, the mode has successfully changed.
What to do if the engineering menu is not opened?
| Xiaomi model | Does the standard method work? | Need an engineering menu? | Features |
|---|---|---|---|
| Redmi Note 10/11 | Yes. | No. | The item "Type of set" is in Settings → System applications → Phone → Tonal set |
| Poco F3/F4 | Yes (MIUI 13+) | Yes (MIUI 12) | Firmware below 13.0.3 may require resetting network settings |
| Xiaomi 12/13 Series | Yes. | No. | Automatically determines the operator’s network mode |
| Redmi 9A/10A | No. | Yes. | Manual input is often required USSD-Operator code (see Method 3) |
Method 3: USSD-switch-off
If the first two methods fail, the operator can block the automatic switching, in which case manual activation of the tone mode through the control system will help. USSD-The commands vary depending on the operator:
- 📞 MTS: Dial *#62#, then 1 (to activate the tone set).
- 📞 Beeline: Enter *110*181# and press the call.
- 📞 Megaphone: Use *105*1# (Confirmation may be required for SMS).
- 📞 Television2: Dial it *155*1# and follow voice instructions.
After sending the team, wait. SMS-If the answer does not come, check the balance (some operators charge for a change of mode, usually 1-3 rubles).
⚠️ Attention: Xiaomi with two SIM-map USSD-commands can only be performed for the main SIM (slot 1) To change the mode of the second SIM, Change your cards temporarily or use another phone.
💡
If USSD-The command doesn't work, try entering it through the Google Phone app (available on the Play Market), which often handles service requests better than the standard Xiaomi Phone app.
How do you know if the regime has really changed?
It's not enough to just turn on the tone set -- you need to make sure that the operator supports it and processes it correctly. Here are 3 ways to check:
- Test call: Call a number with a voice menu (e.g. *100# for Beeline or 0880 for MTS). Press any number - if you hear a high horn (not clicks), the mode is active.
- USSD-query: Type *#06# if it appears on the screen IMEI phone without additional sounds, the tone set works.
- Install the DTMF Tester from the Play Market, which will show you what tonal signals your phone is sending.
If after all the manipulations, the calls are still in pulse mode, the problem may be on the operator's side (DTMF) for my room».
Frequent mistakes and their solutions
When switching modes, Xiaomi users face typical problems, and here are the most common ways to fix them:
- 🔄 Mode resets after reboot: It's a firmware bug. Solution - update MIUI until the latest version or manually install the patch through Settings → The phone. → Updating the system.
- 📵 No sound at tone dial: Check if the call settings are turned off DTMF (is located in the settings of the phone → Sounds and vibrations → Call sounds).
- 🚫 Operator does not support tone dialing: Relevant for virtual operators (Tinkoff Mobile, Yota), the solution is to temporarily switch to the main operator (MTS, Beeline) and activate the mode, then return back to the main operator (MTS, Beeline.
If your Xiaomi model is released before 2018 (e.g. Redmi) 4X or Mi A1), The problem might be hardware incompatibility, and then the replacement will help. SIM-cards to a new (nano-SIM format) or switch to a phone with VoLTE support.
💡
On phones with MIUI 14 and later, the tone mode is activated automatically when the first call to the number with the voice menu. If this does not happen, check the APN settings (the access point should be Internet.mts.ru, Internet.beeline.ru, etc. depending on the operator).
