If you thought 5G was just about faster Netflix streams and lag-free gaming, think again. Vodacom has just ticked off a first for South Africa: a native 5G voice call using Voice over New Radio (VoNR) on its test network. That is tech-speak for “the whole call ran entirely on 5G” without dropping back to older networks like 4G or 3G.
So… what’s the big deal?
Up until now, even if your phone showed that shiny 5G icon, your voice calls were quietly taking the scenic route over older tech. With VoNR, calls stay in the 5G lane from start to finish, offering the following benefits:
- Ultra-clear sound that makes you feel like the person is in the same room.
- Faster call setup with no awkward “Hello? Can you hear me?” delays.
- Better battery efficiency because the phone is not constantly switching between networks.
- Less background noise thanks to improved codec support.
It’s like building the plumbing for the next generation of mobile communication.
The tech behind it
Vodacom pulled this off using Single Packet Core — a cloud-native system that routes both voice and data on one unified backbone. Think of it as ripping out the old wiring in your house and replacing it with a single, high-capacity cable that handles everything faster and more efficiently.
And this is not Vodacom’s first rodeo. They brought VoLTE (Voice over LTE) to South Africa in 2014 and launched commercial 5G in 2020. VoNR is the natural next step.
Why it matters for you
Beyond crystal-clear calls, VoNR opens the door for a range of futuristic features:
- Real-time translation during calls.
- Seamless integration of voice with AR and VR experiences.
- Smarter IoT devices that can talk to you without lag.
If Vodacom moves quickly, you might see this technology become part of your everyday calls sooner than expected. There is no official launch date yet, but the tech is ready.
The competitive angle
Vodacom is first out of the gate in South Africa, but MTN and others are likely to follow. Once one operator shows it is possible, the rest will scramble to keep up. In the mobile industry, nobody wants to be the last one holding the 4G bag.
