Mobile providers across New Zealand are beginning to switch off their 3G networks. We did a full run-down of what's happening and how to be prepared, so be sure to check out our article - 3G Networks Shutting Down in NZ, Here's What to Do.
If you're using a Xiaomi phone, this could mean that you may no longer be able to make or receive calls, unless VoLTE is enabled. This includes emergency calling, so it’s essential to be prepared ahead of time.
The good news? It’s easy to turn on, and we’ll show you how.
What is VoLTE, and why does it matter?
VoLTE stands for Voice over LTE. In simple terms, it means your phone will make calls over the 4G network instead of 3G. This brings some great benefits:
-
Clearer call quality
-
Faster connection times when making calls
-
No slowdowns to your mobile data while you’re on a call
With 3G on its way out, VoLTE is essential to keep calling without interruption.
Xiaomi will release an update soon...
Xiaomi has confirmed that a software update will be rolling out to enable VoLTE automatically on supported models here in New Zealand.
But if you'd prefer to get in early, or want to be sure everything's working before the network changes happen - you can turn it on manually right now.
How to Enable VoLTE on Your Xiaomi Phone
Follow these simple steps (or click here if you prefer a video format):
-
Open the Phone app (where you dial numbers)
-
Type in:
*#*#86583#*#*
-
You will see a pop-up at the bottom of your screen which says "VoLTE carrier check disabled". The VoLTE option should now appear in your Settings.
-
Now go to Settings and tap on SIM cards & mobile networks
-
Select your active SIM (e.g. “SIM 1” or your provider’s name)
-
Scroll down to find VoLTE or Make calls using VoLTE and toggle it ON (if not already enabled)
-
And you’re done!
If you have followed the instructions above carefully, your Xiaomi phone is now good to go. However, if VoLTE still does not connect, you may need to contact your network operator (Spark, One NZ, 2degrees) to confirm your SIM card and account have been correctly provisioned for 4G Calling / VoLTE services. One NZ and 2degrees SIM cards should be automatically set up for VoLTE. If you are a Spark or Skinny customer, you may need to contact them for one-off manual provisioning.

Bonus tip: Enable Wi-Fi Calling too
Wi-Fi Calling (also known as VoWiFi) lets you make and receive calls using your home or office Wi-Fi - a great option when mobile reception is weak indoors.
How to Enable Wi-Fi Calling on Your Xiaomi Phone
Follow these simple steps:
1. Open the Phone app (where you dial numbers)
2. Dial: *#*#869434#*#*
3. The code above enables VoWiFi support. You will see a pop-up confirming that VoWiFi is enabled.
4. Open the Settings app and tap on Mobile Networks
5. Select your active SIM (e.g. “SIM 1” or your provider’s name)
6. Scroll down to Make calls using Wi-Fi and toggle it ON (if not already enabled)
Quick Recap

Thanks so much for this. Got VolTE sorted now. But does that mean I will be able to use 4G, or might my phone still be only 3G compatible and therefore obsolete? It's a Xiaomi Redmi 9T.

Hi Janice. You’re most welcome. Once you have enabled VoLTE, you are good to go. Your phone will still be usable after the 3G shutdown, as it does support 4G.

My phone picks up any 5g network when it is available and seems to use 4g otherwise. But you did get me connected to WiFi calling which is a bonus in our area (rural)

Thanks, this worked 100%. I'm currently roaming in Oz and had no voice calling in or out. One NZ told me that I needed a new compatible phone and that Xiaomi phones were not VoLTE compatible! This fix fixed the voice call issue straight away..thanks again!
