How to completely disable VoLTE on Xiaomi Redmi: 4 working methods

VoLTE Technology (Voice over) LTE) It allows you to make voice calls through 4G-But many Xiaomi Redmi users face problems ranging from occasional call interruptions to increased battery consumption. MIUI The calls were interrupted and the icon HD VoLTE in the status bar is annoying – this article will help bring back the classic mode GSM/3G.

It's important to understand that the procedure for disabling VoLTE differs depending on the Redmi model (e.g. Redmi Note 10 Pro vs Redmi 9A), the MIUI version, and even the carrier. We tested all the methods on the current firmware in 2026 and highlighted the ones that work stably. Below you will find not only the standard methods through the settings menu, but also hidden options for the engineering menu, as well as solutions for cases when the operator forcibly activates VoLTE.

Why VoLTE can interfere: real cases of users

Before we get to the instructions, we will understand in what situations VoLTE is justified, and the analysis of complaints on the 4PDA and Mi Community forums showed that users often face the following problems:

• 📞 Call breaks through 10-30 Seconds after the start of the conversation (especially relevant for Redmi Note) 8/9 on MIUI 13+).
• 🔋 Increased battery consumption – VoLTE module keeps the connection to the network constantly even in standby mode.
• 📶 Poor quality of communication in areas with instability 4G (The call either doesn't pass or the sound is interrupted).
• 🚫 Inability to call when mobile Internet is active (some operators block voice calls through the Internet) 2G/3G, if VoLTE is on).

Interestingly, Redmi with Qualcomm Snapdragon processors (for example, Redmi Note 11 Pro+) problems with VoLTE are less common than on models with MediaTek chips (Redmi 10A, Redmi 9C).

Method 1: Disable VoLTE via standard MIUI settings

The easiest way, which works on most Xiaomi Redmi models (including the Redmi Note 12, Redmi 11 Prime and older devices), is suitable for users who have the option visible in the menu:

2. Go to section. SIM-maps and mobile networks.
3. Choose yours. SIM-card (if two of them).
4. Tap on the network type or preferred network type.

6. Reboot your smartphone so that the changes take effect.

If there is no VoLTE option on the menu, it means that your operator has forced the technology to activate at the SIM-card level (often found in MTS, Beeline and Tele2).

⚠️ Attention: On some firmware MIUI (for example, MIUI 14 Global) after the VoLTE shutdown, mobile Internet may disappear. → Mobile network → Access point (APN) and select the operator profile manually.

Method 2: Use of an engineering menu (for power users)

If the standard method didn’t work, you can turn off VoLTE via a hidden engineering menu, which is universal for all Redmi models, but requires caution – incorrect settings can disrupt the network.

Instructions for smartphones on Qualcomm Snapdragon (Redmi Note 10/11/12, Redmi K40/50):

2. In the menu that appears, select Phone Information (or Phone Information).
3. Scroll down to the Set preferred network type block.
4. Select LTE/WCDMA/GSM auto (PRL) or WCDMA/GSM auto (if you want to disable 4G completely).
5. Click Turn off VoLTE provisioning (if any).
6. Reset the device.

For smartphones on MediaTek (Redmi 9/10/9A/9C) the combination is different:

##36446337##

In the MediaTek engineering menu, go to Connectivity → VoLTE and turn off the option.

⚠️ Attention: On some firmware MIUI When you log in to the engineering menu, you may see a warning, "Network testing mode enabled." This is normal, it will disappear after you restart. Do not change other parameters in the engineering menu unless you are sure of their purpose, this can lead to loss of the network!

Method 3: Disabling VoLTE through SIM-card (if the operator blocks the card)
