Xiaomi smartphone owners often notice the appearance of an obscure VE LTE icon in the status bar next to the signal level, which raises a lot of questions: what does this acronym mean, where did the usual 4G icon go, and whether it hides traffic leakage or unnecessary costs, in fact, it is a regular feature of modern networks that changes the way voice is transmitted.
VoLTE (Voice over LTE) technology allows voice calls to be transmitted directly through the fourth generation network, bypassing switching to 2G or 3G. In the MIUI and HyperOS interface, the acronym VE often acts as a visual marker for activating an advanced voice service.
In this article, we will take a closer look at the technical features of the standard, compare it with its predecessors, and answer the main question of whether the average user should interfere with network settings, learn how to properly activate a function when it is hidden by the operator, and what consequences can have a forced shutdown.
Technological essence of VoLTE and VE marking
To start with, it's a little bit of a terminology. VoLTE stands for Long Term Evolution. Before, when you call from a smartphone, you've had to force it to 2G or 3G, because LTE was originally designed just for high-speed Internet, and it took time, and you could hear the characteristic click or delay before the beeps.
The VE marking in Xiaomi's status bar is a specific designation that the firmware developers have implemented, which indicates that the device is in LTE coverage and ready to transmit high-quality voice. When you see VE LTE, it means that the phone will not "fall" into 3G during a conversation, while the Internet speed remains maximum, allowing you to talk and download files in parallel or navigate on a map.
The key difference is the use of IP-Voice is digitized and transmitted as a data packet, similar to instant messenger messages, but with the highest priority in the operator's network, providing crystal clear sound, free of background noise and interference, characteristic of analog telephony of the past.
⚠️ Attention: Availability of a badge VE LTE Tarication is carried out according to your tariff plan, as in normal minutes, unless the operator has stated otherwise.
Advantages and Disadvantages of Technology for Users
The move to a new communication standard has had some tangible benefits for subscribers, but like any technology, there are nuances that can affect choices in specific environments.
One of the main advantages is that you can set up a phone speed, and you can connect to the person you're talking to almost instantly, and you can also get a much higher quality of sound, and you can talk on speakerphone, and you can have a natural voice without the robot effect or the metallic tint.
But there are downsides, and the main one is the increased battery consumption, and the constant maintenance of LTE connectivity and processing of voice packets requires the resources of the processor and modem, and if you're in a hot spot, the phone will be constantly searching for the network, which will quickly land the battery.
- 🚀 Speed: Instant connection without delay to switch network modes.
- 🔊 Quality: HD-The sound and ability to use the Internet and phone simultaneously.
- 🔋 Autonomy: In low signal conditions, battery consumption can increase to 20%.
- 📡 Compatibility: Support from operator and SIM card is required.
Also worth noting is the compatibility issue: not all carriers and not all tariff plans support this feature out of the box. Sometimes you need to manually activate the service in your personal account or through a call to customer service. Without this, the VE icon may not appear, even if the phone is technically ready.
Comparison of VoLTE with Wi-Fi Calling and 3G
To understand the technology's place in the communications ecosystem, we need to compare it to alternatives. VoLTE is often confused with Wi-Fi Calling, although these are different mechanisms. One works through cell towers, the other through a router's Wi-Fi hotspot.
The table below will help to clearly see the differences in the characteristics and working conditions of different types of communication.
| Parameter | VoLTE (VE LTE) | Wi-Fi Calling | 3G / 2G |
|---|---|---|---|
| Basis of work | LTE network of the operator | Internet (Wi-Fi) | GSM/UMTS networks |
| Sound quality | High (HD) | Depends on the speed of Wi-Fi. | Low/Mediocre |
| Traffic consumption | Not charged (usually) | Wi-Fi traffic is being consumed | Not tariffed. |
| Roaming work | Depends on the operator. | Often free. | Expensive. |
Unlike Wi-Fi Calling, which saves in basements or abroad, VoLTE provides stability in movement. You can leave the building and the call will not be interrupted, since the device will smoothly transfer the connection from router to tower (if Handover is configured) or simply hold LTE. Old 3G networks in this regard lose: when leaving the Wi-Fi zone, the call often breaks.
It's important to understand that VoLTE uses data channels, but doesn't consume your Internet traffic. Operators allocate a separate priority channel (QoS) to voice, so gigabytes from the package are not debited. This is a common mistake of users who are afraid to turn on the feature because of (fear) being left without the Internet.
How to enable or disable the feature on Xiaomi
Managing this option on Xiaomi smartphones can be in different places depending on the version of MIUI or HyperOS. Usually the path looks standard, but sometimes you need access to a hidden menu.
For standard activation, go to Settings → SIM-Select the SIM card and find the switch Use VoLTE. If the slider is active but the icon does not appear, then the operator has not transmitted the corresponding profile to the device.
In some cases, especially on global firmware versions for Russian operators, the item may be hidden. Then you will have to use an engineering menu or a special code. Enter the command # #86583## in the dialer. After you enter, you should see the message "VoLTE carrier check was DISABLED." This means that the artificial restriction is removed and the item in the settings will be available.
☑️ Testing of VoLTE Readiness
⚠️ Note: If after turning on the function, the Internet disappeared or SMS stopped coming, try restarting the device or resetting the network settings to the factory.
Effects on battery charge and communication stability
The issue of power consumption is acute for many users: a modem that operates in a continuous LTE mode consumes more power than a 2G standby mode. However, modern Qualcomm and MediaTek processors have learned to manage these processes effectively.
If you're in a city with great coverage, the discharge difference is minimal, about 3-5% per day. The problems begin in gray areas, where the phone is tossed between 4G and 3G. In such cases, the VE LTE icon can appear and disappear, causing constant reconnection and heating of the case.
To test the impact of the technology on your particular machine, you can do a simple test: measure your charge level in the morning, spend the day with VoLTE on, and the next day with it off, and the difference will help you make an informed decision.

Solving Typical Problems and Errors
Users often face a situation where the function is enabled in the settings, but does not work. VE icon does not burn, calls go through 3G. First of all, check if the service is activated on the operator's side. On the sites "big three" and Tele2, you can do this in your personal account.
Another common problem is that the system files may conflict with the operator's profiles, in which case resetting the APN settings to (by default) helps. Find the access point in the mobile network menu and select Reset.
If nothing helps, maybe yours. SIM-The card is too old and does not support the standard. USIM. Replacing the SIM in the communication salon in 5 minutes will solve the compatibility problem.
- 🔍 Check the status of the service in the operator's application.
- 🔄 Reset your network settings (not to be confused with a full phone reset).
- 💾 Update the operator database in the settings SIM-map.
- 📞 Call support to check the profile on the network side.
💡
If you often travel to areas where 4G catches poorly, it is better to turn off VoLTE.This will save charge and prevent permanent connection breaks when switching between towers.
💡
VE LTE is the standard of modern communication quality, and if your phone and carrier support it, keeping it on is more beneficial for comfort than putting up with long dialing and bad sound.
