India’s telecom industry is evolving faster than ever. What started as a simple voice and SMS revolution has now entered the era of ultra-fast 5G and AI-driven networks. Today, there are four major telecom players in the country — Reliance Jio, Bharti Airtel, Vodafone Idea (Vi), and BSNL.
Among these, Reliance Jio stands out not only as the newest player but also as the most technologically advanced. After introducing 4G VoLTE across India, Jio has now rolled out a brand-new upgrade called VoNR — which stands for Voice over New Radio.
This new feature promises crystal-clear 5G voice calling, lower latency, and a smoother call experience than ever before. In this article, we’ll explore everything about Jio VoNR technology, how it works, what makes it different from VoLTE, and how you can enable it on your phone.
📶 1. What Is Jio VoNR Technology?
VoNR stands for Voice over New Radio, and it’s the next-generation voice calling technology built on 5G.
In simple terms, VoNR allows users to make and receive voice calls directly through the 5G network, without falling back to older 4G (LTE) networks.
Traditionally, even when your phone displayed a “5G” icon, your calls still used VoLTE (4G) technology. But with VoNR, that dependency is gone — your voice data travels purely through the 5G standalone network, resulting in faster connection, clearer sound, and lower latency.
According to Jio’s Vice President Ayush Bhatnagar, the VoNR system is completely indigenous — designed and developed using Jio’s own 5G infrastructure, without reliance on imported software for core voice operations.
This marks a major milestone for India’s telecom industry, showcasing that homegrown technology can compete globally.
⚙️ 2. How Does VoNR Differ from VoLTE?
To understand how big this upgrade is, let’s quickly compare VoNR with the older VoLTE system.
| Feature | VoLTE (4G) | VoNR (5G) |
|---|---|---|
| Full Form | Voice over LTE | Voice over New Radio |
| Network Used | 4G LTE | 5G Standalone |
| Call Setup Time | Slightly slower | Instant (ultra-low latency) |
| Voice Quality | HD (High Definition) | Super HD / Crystal Clear |
| Call Drops | Occasional | Significantly reduced |
| Battery Usage | Higher (due to fallback switching) | Lower (direct 5G connection) |
| Data + Voice | Switches between 4G for calls & 5G for data | Both run simultaneously on 5G |
In short:
- VoLTE relied on 4G for voice calls, even when you had 5G data.
- VoNR uses 5G for both — data and voice.
This makes your calls faster, clearer, and more reliable.
🌐 3. How Jio Implemented VoNR Across India
Reliance Jio began its 5G rollout back in October 2022, partnering with Nokia and Ericsson for hardware deployment. Over time, it expanded the network to cover almost all major Indian cities.
Now, with VoNR officially rolled out nationwide, Jio has completed the most crucial step of 5G voice integration.
Unlike hybrid 5G solutions that rely partially on 4G infrastructure (called non-standalone 5G), Jio’s VoNR is built on a true standalone (SA) 5G network — using its own indigenous 5G core.
This is a huge achievement, as it means Jio can manage voice, data, and network traffic entirely on Indian soil, offering better security, control, and quality assurance.
🧠 4. How VoNR Works — The Technical Explanation
Now, let’s understand how this technology works behind the scenes in simple terms.
When you make a call using VoNR:
- Your voice is converted into digital packets.
- These packets are transmitted directly through the 5G network’s radio interface (NR).
- The system then routes the call entirely via Jio’s 5G core, instead of the older LTE system.
- The receiver’s phone decodes these packets — enabling crystal-clear audio.
Unlike VoLTE, there’s no fallback to 4G, meaning your connection stays on pure 5G from start to finish.
This direct communication reduces:
- Network handovers
- Call setup delays
- Packet loss (which causes robotic or muffled sound)
The result: faster connection, near-zero distortion, and seamless switching between data and voice activities.
🌟 5. Benefits of Using Jio VoNR
Now that we understand what it is, let’s explore why it matters.
Here are the main advantages of Jio’s new VoNR system for everyday users:
1. Crystal-Clear Voice Calls
Thanks to full 5G utilization, your voice quality improves drastically — offering “super HD” clarity that feels more natural and lifelike.
2. Faster Call Connection
No more long wait times before a call connects. VoNR uses low-latency signaling, enabling calls to connect within a second.
3. Reduced Call Drops
Because VoNR doesn’t rely on switching between networks, the chance of a dropped call decreases significantly.
4. Improved Battery Efficiency
Older VoLTE systems often drained battery as phones switched between 4G and 5G. VoNR’s stable 5G connection consumes less power.
5. Better Video and Voice Sync
If you use video calling apps that support VoNR (or similar APIs), you’ll notice smoother synchronization between video and audio streams.
So far, we’ve learned what makes VoNR better. Now let’s move to something practical — how to turn it on.
📱 6. How to Enable VoNR on Your Smartphone
Most 5G smartphones sold in India already come with VoNR compatibility, but it may not be activated by default.
Here’s how you can manually enable it on your device.
Step-by-Step:
- Open Settings on your smartphone.
- Go to Mobile Network / SIM settings.
- Select your Jio SIM from the list.
- Look for an option named VoNR, 5G Calling, or Voice over 5G.
- Toggle it ON.
Once activated, your internet may pause for a few seconds. After reconnection:
- The signal bar may display “Vo5G” or “VoNR”.
- This indicates that the 5G voice calling feature is now active.
🔁 If It Doesn’t Work:
- Restart your phone once.
- Ensure that 5G is enabled in your region.
- Check that you have a Jio True 5G plan (regular 4G plans may not support VoNR).
⚠️ 7. Common Issues and How to Fix Them
Sometimes, even with 5G coverage, users may not see the VoNR icon. Here are a few quick troubleshooting tips:
| Problem | Possible Reason | Solution |
|---|---|---|
| VoNR toggle missing | Outdated phone firmware | Update to the latest software version |
| Call still shows VoLTE | Network fallback in your area | Try again in full 5G coverage zone |
| Internet disconnects during call | Temporary signal handover | Wait a few seconds; it reconnects automatically |
| No 5G option at all | Your SIM or plan may be old | Replace SIM and upgrade to a Jio 5G plan |
If the problem persists, you can visit the nearest Jio Store or contact Jio Customer Care (198) for assistance.
📲 8. Which Phones Support Jio VoNR?
Most 5G-enabled smartphones launched after 2022 support VoNR, including major brands like:
- Samsung Galaxy S21 series and above
- OnePlus 9, 10, 11, and Nord 3 series
- iQOO, Realme, Xiaomi, Oppo, and Vivo 5G models
- Apple iPhones (iPhone 13 and newer, post software update)
✅ Tip: You can check by visiting your phone’s “About” section → “Network Type.” If you see “SA” or “VoNR” under 5G mode, your device is ready.
🔋 9. Impact of VoNR on Battery and Network Performance
One of the biggest advantages of VoNR is optimized power usage.
Since the call no longer switches between 4G and 5G, your phone’s modem works more efficiently, consuming less battery per minute of call time.
Additionally, network stability improves, resulting in:
- Reduced heat generation
- Lower ping times for apps running in the background
- Simultaneous data and voice transmission without interruption
This is especially beneficial for users who multitask — for example, making a call while using Google Maps or streaming music.
🗺️ 10. VoNR Rollout Timeline and Availability
As of now, Jio VoNR is available nationwide across all major 5G zones in India.
The rollout began in early 2024 and is gradually being expanded to every Jio True 5G tower.
If your city has Jio 5G coverage, you likely already have access to VoNR. For smaller towns, the rollout is expected to complete by the end of this year.
