How to enable VOLTE on Xiaomi Redmi Note 9 ?
Ikshu Mukopadhyay   1 years ago

You don't need to enable VoLTE. Insert the Jio (VoLTE enabled) in any slot. By default, VoLTE will be active. If it is not, you can change the network preferences from Network option in settings.

Go to Settings > Call Settings (Sim and Network)
Tap Cellular networks > Enable Voice over LTE On/ Off.


Alternatively, you can follow a much easier way:

You can simply dial *#*#4636#*#*
Choose Phone information.
Click " Phone Information" and Toggle VOLTE Provisioned.
Restart the phone and you are done.


You can check the below video to get more clarity:

Enable VoLTE and VoWifi on Xiaomi handsets

I have recently had trouble making outbound calls due to network congestion. I guess all the people working from home have overloaded my neighbourhood's cell tower. It was suggested by a friend that I check to see if VoLTE and VoWifi were enabled. Maybe I'm way out of touch, but I had no idea my Mix 2 (global) was capable of VoLTE or VoWifi. The options simply don't exist in settings. But they can be unlocked.

To unlock VoLTE: open your phone app and dial *#*#86583#*#*
To unlock VoWifi: open your phone app and dial *#*#869434#*#*

Now go into Settings > Sim Cards & Mobile Networks. You will see an option called "VoLTE enabled". Tap the switch to enable it. Scroll down further and you will see another option called "Make calls using Wi-Fi". Tap the switch to enable it. You can then choose whether the phone should prefer network or wifi right below.

This will depend on your provider supporting these options. And you could burn through data if they charge you for that on VoLTE calls.

I have no idea whether these steps work for all Xiaomi handsets, but I suspect it works for anything on MIUI11.
