What is VoLTE?

VoLTE Calls Meaning: Breaking It Down

VoLTE, or Voice over LTE, is a technology that routes your voice calls through the 4G LTE data network instead of the older 2G or 3G voice networks. Think of it like upgrading from analog to digital, or from standard video to HD. With VoLTE, your calls benefit from faster connection times, clearer sound quality, and the ability to use data and voice simultaneously.

Before VoLTE became mainstream, your phone would typically drop from 4G to 3G or 2G during a voice call. This not only led to lower voice quality, but also disrupted data access—you couldn’t browse the web or use apps that needed the internet while on a call. VoLTE solves this problem by allowing everything to work on the same 4G network, all at once.

What Are VoLTE Calls and Why They Matter in 2025

With major telcos in Singapore like Singtel, StarHub, M1, and Circles.Life embracing VoLTE, it's rapidly becoming the new standard. In fact, many providers are already phasing out older 2G/3G networks, making VoLTE not just a feature but a necessity.

Whether you’re making personal calls, joining a Zoom meeting via your mobile, or needing high-speed data while on a business call, VoLTE gives you seamless, efficient communication. For users in dense cities like Singapore where network traffic is high, the speed and stability of VoLTE offer a noticeable difference in day-to-day use.

VoLTE vs. Non-VoLTE Calls

Let’s compare VoLTE calls with traditional voice calls over 2G or 3G networks. Understanding the difference helps users appreciate why enabling VoLTE is a smart move.

Key Takeaways:

• HD Voice Quality: VoLTE offers clearer, more natural-sounding conversations, making it easier to understand the other person, especially in noisy environments.

• Simultaneous Voice and Data: No need to pause Spotify or YouTube just to answer a call. VoLTE keeps your apps running in the background.

• Faster Call Setup: VoLTE reduces the time it takes for the other party to pick up or connect—typically in under 1 second.

• Future-Ready Network: As 2G and 3G are sunsetted, VoLTE ensures your device stays compatible with today’s and tomorrow’s networks.

How to Enable VoLTE on Your Phone

Activating VoLTE is typically a one-time process, but it varies slightly between devices and operating systems. Let’s break it down for both Android and iPhone users.

Enable VoLTE on Android Devices

Follow these steps to enable VoLTE on most Android phones:

1. Open your phone’s Settings.

2. Tap on Network & Internet or Connections (name varies by brand).

3. Select Mobile Network.

4. Scroll down to find VoLTE Calls or Enhanced 4G LTE Mode.

5. Toggle the switch ON.

6. Restart your phone if prompted.

Brands like Samsung, OPPO, Xiaomi, Google Pixel, and OnePlus all support VoLTE—but the settings menu may differ slightly.

By improving call clarity and maintaining a stable internet connection, VoLTE enhances everything from casual chats to mission-critical conversations.

Why VoLTE Matters for MVNOs and SIM-Only Users

If you're using a SIM-only plan from providers like Circles.Life, Gomo, Giga, or Zero1, you’ll want to confirm that VoLTE is supported. The good news is that many of Singapore’s MVNOs already offer VoLTE on compatible phones and networks.

Benefits for SIM-Only Users:

• Contract-free but future-proof: Enjoy modern features like VoLTE without the need for expensive telco bundles.

• Better Quality Without Higher Costs: VoLTE is included in standard voice plans—no need to pay extra.

Circles.Life users, for example, can activate VoLTE on both physical SIM and eSIM—ensuring you get top-tier call performance with complete plan flexibility.

Can I Use VoLTE for International Calls or Roaming?

Yes—but it depends on your carrier’s agreements with foreign networks. Here's a closer look:

When VoLTE Works While Roaming:

• You’re in a country with compatible LTE bands.

• Your home carrier has a VoLTE roaming agreement with the local provider.

• Your device is unlocked and VoLTE-enabled.

When VoLTE May Not Work While Roaming:

• The destination country doesn't support VoLTE.

• Your local telco falls back to 3G/2G for voice calls abroad.

• Your plan doesn't include VoLTE roaming support.

If you travel frequently and want the best calling experience, it’s worth checking if your provider offers VoLTE roaming or alternatives like Wi-Fi calling, which can deliver high-quality voice even when abroad.

VoLTE and eSIM: A Powerful Combination

VoLTE becomes even more powerful when paired with eSIM technology, which is becoming increasingly common in newer phones like the iPhone 14, Samsung Galaxy S series, and Google Pixel devices.

Benefits of Using VoLTE on an eSIM:

• Dual Network Access: Use two numbers simultaneously with VoLTE active on both—ideal for separating work and personal life.

• Instant Activation: Activate your plan and enable VoLTE without waiting for a physical SIM card.

• Better Battery Life: VoLTE can be more energy-efficient on eSIMs with optimized settings.

Circles.Life, for instance, supports VoLTE on its eSIM and physical SIM plans, giving users full flexibility in how they connect.
