How to enable VoLTE on Xiaomi Redmi Note 8 Pro: a complete guide with compatibility check

Xiaomi Redmi Note 8 Pro is one of the most popular mid-range smartphones, but many owners still don’t use its full potential.VoLTE (Voice over LTE) technology, which allows you to call over a 4G network rather than switch to outdated 2G/3G. This means faster connection, better sound quality and the ability to talk and use mobile Internet at the same time.

However, enabling VoLTE on the Redmi Note 8 Pro is not as easy as it sounds: it can be hidden in settings, blocked by the operator or require a firmware update. In this article, we will discuss all the ways to activate, including manual settings, checking for operator support and solving typical problems. If you are tired of Internet interruptions during calls or want to improve the quality of communication, read on.

What is VoLTE and why should it be enabled on the Redmi Note 8 Pro?

VoLTE (LTE voice) is fundamentally changing the way we approach voice communication, and instead of switching to a traditional 2G/3G network during a call, the smartphone stays on the 4G network, which has several key benefits:

  • πŸ“ž Instant connection – the call connects 2-3 times faster than when used 3G.
  • 🎧 Sound quality HD β€” broadband LTE It allows you to transmit voice in high resolution (up to 24 kHz vs. 8 kHz in the voice). 3G).
  • πŸ“Ά Without breaking the internet – you can continue downloading files, watching videos or playing online while you’re in conversation.
  • πŸ”‹ Saving charge – no need to constantly switch between networks, which reduces the load on the modem.

Redmi Note 8 Pro supports technology at the hardware level (Meditek Helio chipset) G90T VoLTE compatible, but often disabled by default, and the reasons range from operator policies to regional firmware restrictions, such as in some countries, VoLTE activates automatically when inserted. SIM-maps, and in Russia or Ukraine requires manual adjustment.

Step-by-step: how to turn on VoLTE on Redmi Note 8 Pro

If the carrier supports the technology, we'll move on to setting up the smartphone, and there are two main ways to activate it: through the standard menu and through the engineering mode (for advanced users), starting with the simplest.

Method 1: via MIUI settings (official method)

This method works on most MIUI 12-14 firmware and does not require root permissions.

  1. Open the Settings. β†’ SIM-maps and mobile networks.
  2. Choose yours. SIM-card (if there are several).
  3. Tap on the network type (or preferred network type).

Firmware Update: Why it’s important for VoLTE

On the Redmi Note 8 Pro with firmware older than MIUI 12.0.3, VoLTE may not be available at all, even if the carrier supports it, because Xiaomi has been gradually adding support for the technology in updates, and early versions of the software simply did not have the necessary drivers to work with voice over LTE.

To update the firmware:

  1. Go to Settings β†’ About the phone β†’ System update.
  2. Click Check Updates and wait for the latest version to download.
  3. If the update is not available, check the firmware region: 🌍 Russia should be the region of Russia or EEA (Europe). πŸ”„ If it is China or India, VoLTE may not work – you will need to flash it to the global version.

After the update:

  • πŸ”„ Reboot the phone.
  • πŸ“± Check the appearance of the VoLTE item in the settings SIM-map.
  • πŸ“‘ If the feature never appeared, try resetting the network settings (Settings) β†’ SIM-map β†’ Resetting mobile network settings).

πŸ’‘

If VoLTE doesn’t work after the update, try inserting it. SIM-card to another slot (if there are two) Sometimes the function is activated only for the slot SIM1.

Frequent problems and their solutions

Even after you set up the right VoLTE, it may not work, and let's look at the common bugs and how to fix them:

Problem.Possible causeDecision
No VoLTE item in the settingsOutdated firmware or region of ChinaUpdate MIUI to 12+ or upgrade to the global version
VoLTE is turned on, but calls go through 3GThe operator has not activated the service for your number.Call support or send it. USSD-request (see table above)
After the inclusion of VoLTE, the Internet disappearedConflict APN-settingsReset your mobile network settings or set up your APN manually
Calls are interrupted or poorly heardWeak 4G signal in your areaTemporarily disable VoLTE or use Wi-Fi Calling

If none of the methods worked, check:

  • πŸ“‹ Type SIM-Cards: VoLTE only works with USIM (A new microchip. A regular one. SIM Check with the operator's cabin.
  • πŸ“‘ Coverage 4G: If there is a weak signal in your area LTE, The smartphone can automatically switch to 3G. Check the coverage on the operator's website.
  • πŸ”§ Application conflict: Some programs (such as Freedom or AdGuard) block VoLTE. VPN firewall.
What if the VoLTE never worked?
If you’ve tried all of these methods, but VoLTE still doesn’t work, there are two options: 1. Alternative firmware: Install custom software (like Pixel Experience or LineageOS) where VoLTE support is implemented better. 2. Wi-Fi Calling: Activate Wi-Fi calls (Settings) β†’ SIM-map β†’ This won't replace VoLTE entirely, but it will allow you to make Internet calls in areas with poor coverage, both of which require firmware experience or service center support.

VoLTE vs Wi-Fi Calling: What’s Best for the Redmi Note 8 Pro

Many people confuse VoLTE and Wi-Fi Calling, but these are different technologies with different advantages.

  • πŸ“Ά VoLTE: βœ… It works through a mobile network. 4G. βœ… No Wi-Fi connection required. βœ… Best sound quality in the coverage area LTE. ❌ It doesn't work at a weak signal. 4G.
  • πŸ“Ά Wi-Fi Calling: βœ… It works over any Wi-Fi network. βœ… Useful in areas with poor mobile coverage (basements, remote areas). ❌ Quality depends on the speed of Wi-Fi. ❌ Maybe not roaming.

On the Redmi Note 8 Pro, both features can be used simultaneously.

  • πŸ™οΈ In a city with a good 4G β€” give preference to VoLTE.
  • 🏑 At home or at work, where Wi-Fi is more stable than mobile network – turn on Wi-Fi Calling.
  • πŸš— On trips where coverage is unstable – leave both features active for automatic switching.

To enable Wi-Fi Calling:

  1. Go to Settings. β†’ SIM-maps and mobile networks.
  2. Choose yours. SIM-map.
  3. Activate the Wi-Fi Calling switch.
  4. At the first turn on, confirmation via SMS (depending on the operator) may be required.

πŸ’‘

VoLTE and Wi-Fi Calling are not in conflict; they can (and should) be used together for maximum stability.

How to Check if VoLTE Really Works

Once activated, it’s important to make sure that calls are actually going over 4G, not over legacy networks.

  1. πŸ“ž When you call: Look at the network indicator in the status bar. If it's displayed there. 4G or LTE (not 3G or+) β€” VoLTE works. Some firmware shows an icon next to the signal level. HD VoLTE.
  2. πŸ“Š From the engineering menu: Enter the code ##4636##. Go to Phone Information. See Voice Network Type. LTE β€” everything is right.

Using applications

  • Install NetMonster or Network Cell Info Lite from Google Play. These utilities show the type of network when you call.

If the indicator shows 3G or H+ during a conversation, then VoLTE is not active.

  • πŸ”„ Reboot the phone.
  • πŸ“Ά Manually select the network 4G in settings (Only LTE).
  • πŸ“ž Try calling another number – sometimes the first call after activation goes through the phone. 3G.
