Understanding VoLTE: What It Is, How It Works, and Why You Need It (2024)

VoLTE, or Voice over LTE, is a game-changer for mobile calls. If you’ve ever wondered why your voice calls aren’t as clear as streaming audio or why your internet slows down during a call, VoLTE is the answer you’ve been looking for. In this guide, we’ll break down what VoLTE is, how it works, how to turn it on or off, and why it’s worth using

What is VoLTE?

VoLTE (Voice over Long-Term Evolution) is a technology that enables you to make voice calls over a 4G LTE network rather than traditional voice networks like 2G or 3G. When making a call with VoLTE, your phone uses the same network as your data, improving call quality and connection speeds.

How Does VoLTE Work?

Traditional mobile calls rely on older networks like 2G or 3G, which handle voice and data separately. But when you’re connected with VoLTE, voice and data travel on the same LTE network, making communication more efficient. Here’s how it works:

  1. High-Quality Voice Transmission: VoLTE uses a wider frequency range for voice calls, enabling high-definition (HD) audio, which provides clearer, crisper sound quality.
  2. Simultaneous Voice and Data: With VoLTE, you can make a voice call and use data simultaneously on 4G LTE without slowing down your internet connection. This means you can browse the web, use apps, or stream videos during a call without interruption.
  3. Reduced Call Setup Time: VoLTE minimizes the time it takes to connect a call, making it faster than the traditional calling process.

Why is VoLTE Important?

VoLTE is a big step forward for mobile technology, providing benefits that older networks can’t match. Here’s why it’s worth having:

  • Enhanced Call Quality: VoLTE calls offer HD quality, which means you’ll hear and be heard more clearly, even in noisy environments.
  • Faster Call Connection: Traditional calls can take several seconds to connect. VoLTE calls connect almost instantly, offering a smoother experience.
  • Battery Efficiency: Since VoLTE keeps your phone on one network instead of switching between 4G LTE (for data) and 2G/3G (for voice), it saves battery power.
  • Extended Coverage: Many carriers are phasing out 3G networks, meaning that without VoLTE, you might lose service in some areas.

How to Enable or Disable VoLTE

Turning VoLTE on or off is easy, but the steps may vary depending on your device and carrier.

On iPhone

  1. Open Settings: Go to your Settings app.
  2. Tap on Cellular: Select Cellular (or Mobile Data).
  3. Select Cellular Data Options: Tap Cellular Data Options and then Voice & Data.
  4. Enable VoLTE: Choose LTE, VoLTE On to enable it, or select LTE, VoLTE Off to disable it.

On Android

  1. Open Settings: Go to your Settings app.
  2. Tap on Network & Internet: Look for Network & Internet or Connections (options may vary).
  3. Select Mobile Network: Choose Mobile Network or Cellular Network settings.
  4. Enable VoLTE: Toggle VoLTE or 4G Calling on or off.

Note: If you don’t see VoLTE options, it may be because your device or carrier does not support it, or it’s automatically enabled.

Pros and Cons of Using VoLTE

VoLTE has clear benefits, but let’s break down both sides so you can decide if it’s right for you.

Pros

  • Crystal-Clear Voice Quality: VoLTE is the closest you’ll get to in-person audio quality during a call.
  • Simultaneous Voice and Data Usage: With VoLTE, you don’t have to choose between making a call and using your data.
  • Reduced Battery Consumption: Keeping your phone on one network prevents battery drain from network switching.

Cons

  • Dependent on Network Coverage: VoLTE requires a strong 4G LTE signal, so in areas with poor LTE coverage, it may not work well.
  • Compatibility Issues: Some older devices don’t support VoLTE, and not all carriers offer full VoLTE compatibility.
  • Potential Data Use During Calls: VoLTE may use a small amount of data for call connections, though it’s typically minimal.

What if I Don’t Have VoLTE?

If your device or carrier doesn’t support VoLTE, you may experience:

  • Lower Call Quality: Standard voice calls on 2G or 3G are typically less clear.
  • No Simultaneous Voice and Data: You won’t be able to browse or use apps while on a call without VoLTE.
  • Battery Drain: Switching networks for voice and data drains more battery power.

With major carriers moving away from older networks, upgrading to a VoLTE-compatible phone or enabling the feature can significantly improve your calling experience.

Final Thoughts

VoLTE is more than just a high-quality call—it’s a modern upgrade that brings speed, clarity, and efficiency to your mobile experience. If you want to enjoy HD voice quality and a more reliable connection, it’s worth ensuring VoLTE is enabled on your phone. And with major carriers phasing out older networks, VoLTE isn’t just a luxury; it’s fast becoming a necessity.

Whether you’re chatting with family, friends, or colleagues, VoLTE makes sure every word is heard loud and clear. So go ahead, check if VoLTE is enabled on your device, and experience the difference in call quality.
