What is VoLTE Call and How to Enable It

Introduction: Why VoLTE Matters in 2025

In an era where we expect smooth voice calls, quick data streaming, and minimal signal drops, VoLTE calls have quietly become a game changer. But what is VoLTE, really? Is it just another tech buzzword, or something essential to your daily mobile experience?

This guide breaks it all down: the meaning of LTE and VoLTE, how VoLTE voice call technology works, how to enable VoLTE on Android and iPhone, and why it matters more than ever with 4G and 5G networks taking over. Whether you're curious about VoLTE roaming, wondering how it's different from VoWiFi or VoIP, or just trying to get clearer calls—this is your go-to resource.

What is VoLTE? (VoLTE Calls Meaning)

VoLTE, short for Voice over LTE, allows you to make high-quality voice calls using your 4G LTE network instead of the traditional 2G/3G networks.

With VoLTE, your calls no longer drop or pause your data connection. You get faster call setup times, HD voice clarity, and better multitasking, such as browsing while calling.

LTE vs VoLTE

• LTE (Long-Term Evolution) is the standard for 4G data, optimized for internet, not voice.

• VoLTE upgrades LTE by adding real-time voice calling functionality.

In short: LTE is fast data. VoLTE adds voice to the speed mix.

Meaning of LTE and VoLTE

To fully grasp VoLTE calls, let's start with the basics.

• LTE (Long-Term Evolution) is the high-speed 4G data highway.

• VoLTE (Voice over LTE) is a voice calling service that rides on LTE, removing the need to fall back to 3G or 2G.

Without VoLTE:

• Your phone drops to 3G when making calls.

• Data is interrupted during calls.

With VoLTE:

• You stay on 4G.

• Calls sound clearer.

• The Internet stays uninterrupted.

How Does VoLTE Work?

So, how does VoLTE work technically?

VoLTE uses something called IP Multimedia Subsystem (IMS). This lets your voice call travel as data packets over LTE networks. Instead of switching channels, your device uses end-to-end IP-based technology to handle voice with reduced latency.

In simple terms:

1. You make a call.

2. Your voice is turned into data.

3. That data rides the LTE network.

4. The result? Faster, clearer, smarter calls.

What Do You Need To Make VoLTE Calls?

Here’s what you need to experience the full benefits of VoLTE voice call quality:

• VoLTE-supported phone: Most modern Android and iOS devices are compatible.

• Updated software: Ensure your OS is up-to-date.

•  VoLTE-enabled SIM card: Provided by your carrier (like Circles.Life).

• 4G LTE network coverage: Your location must be within range.

• VoLTE activated in phone settings: More on this below.

How to Enable VoLTE

Wondering how to enable VoLTE on your phone? Here’s how:

Enable VoLTE on Android:

1. Go to Settings > Connections or Mobile Network

2. Tap Network Mode or Preferred Network

3. Enable VoLTE calls or Enhanced 4G LTE Mode

Depending on your phone brand, it might be:

• “VoLTE calls”

• “4G calling”

• “Enhanced 4G LTE Mode”

If you don’t see it, check if your SIM or device supports VoLTE, or contact your carrier.

Enable VoLTE on iPhone:

1. Go to Settings > Mobile Data

2. Tap Mobile Data Options > Voice & Data

3. Select 4G, VoLTE On

Once VoLTE is enabled, your phone should default to using LTE for all calls.

Benefits of VoLTE Voice Call

VoLTE isn’t just about clearer calls—it’s an all-around upgrade. Here’s why it matters:

• HD Call Quality: Hear the other person like they're next to you.

• Simultaneous Voice & Data: Browse, stream, and scroll during a call.

• Faster Call Setup: Calls connect in under 1 second, compared to 4-6 seconds on 3G.

• Better Battery Life: No switching between 4G and 3G saves power.

• Stronger Indoor Signal: LTE penetrates buildings better than legacy networks.

Especially in 2025, where 3G is being phased out in many countries, VoLTE is essential.

VoLTE Compared: VoLTE vs VoWiFi vs VoIP vs 5G (VoNR)

Not all modern calling technologies are the same. Here's how VoLTE compares with others:

Each option has its niche, but VoLTE offers the perfect middle ground of reliability, quality, and compatibility today.

VoLTE Roaming: Can You Use VoLTE Overseas?

Yes, VoLTE roaming is available, but it depends on:

• Your phone model

• Carrier support (some partner with international networks)

• Regional VoLTE coverage

Tip: If you’re traveling, always check if you're roaming SIM or carrier enables VoLTE abroad to maintain good call quality.

What Is the Difference Between LTE and VoLTE?

In summary, LTE is your data lane, while VoLTE opens up a voice lane on the same fast highway.

Future of VoLTE in 2025 and Beyond

As 3G continues to sunset globally and 5G matures, VoLTE is the default for most mobile carriers. It's not optional anymore—it’s the standard for voice calling on LTE networks.

Expect:

• Wider VoLTE roaming support

• Improved HD+ voice codecs

• Seamless transitions between VoLTE and 5G VoNR

Troubleshooting: Why Can’t I See the VoLTE Option?

If you don’t see VoLTE in your phone settings, here’s what to check:

• Is your phone updated?

• Is VoLTE supported by your model?

• Is your SIM card VoLTE-ready?

• Are you in a VoLTE coverage zone?

Still not working? Contact your carrier’s customer support to activate VoLTE.

Final Thoughts

Understanding what VoLTE is, its benefits, and how to enable VoLTE is crucial in 2025, especially as mobile networks evolve. VoLTE is no longer a feature for techies—it’s the new normal for voice calling. It improves how you call, where you can call, and how well you’re heard. Whether you’re enabling VoLTE on Android or iPhone, it’s a small step with a big impact.
