Open the Dialer. enter this code – *#*#869434#*#* Once you dial, you'll get a small notification saying “Vowifi carrier check was disabled”
Go to settings, networks and sim, go down to the bottom, activate the Wi-Fi calling option and then select Prefer Wi-Fi.
connect to a wifi network and see if the VOWIFI symbol appears at the top where the coverage is

Ok so most of the roms support volte but I feel that the jio volte in these rom is very unstable(atleast in my region). This is not the developer's fault, this is the problem of jio.
Solution:
1. Go to play store and install "Network Signal Guru". Open the app, give it root permissions.
2. Now open the dialer and dial 198, if volte works then your should be able to make the call. Now if the call didn't connect then you have to do trial and error by restarting the phone, then again try, etc. If you completely fail to connect the call, then I'll explain what to do at the end of this thread.
3. If the call connects then instantly go to the Network Signal Guru app and check on which band jio is working(swipe right or left and you'll be able to see 'LTE Band', see attachment).
4. Now click on three dots at the upper right corner, and select lock bands. Uncheck all the bands except the band on which jio is working(for me it was B03, see attachment), click on ok.
5. VoLTE will work in your region perfectly.
If you want to set everything back to normal then again open the app click on three dots and click on clear forcing, click on ok. If your call didn't connect completely then simply force every single lte band and see which band is working for you.
I managed to successfully change the carrier policies on my OnePlus to enable VoWifi and VoLTE in Australia using the guide here: https://forum.xda-developers.com/t/volte-vowifi-and-5g-in-aus.4284047/#post-85119383
My colleague has a Xiaomi Mi 10T Pro - is there a similar set of instructions available to enable VoWifi and VoLTE on that phone in Australia?
In NZ I had success using these Phone codes that turned on VoLTE for me (no VoWIFI for my network). These seem to be standard codes for Xiaomi worldwide that enable support if the underlying software recognises your network's version.
To turn on VoLTE: open your phone app and dial *#*#86583#*#* and you'll see a quick toast message saying it's turned on. Type the code again to turn it off.
To turn on VoWifi: open your phone app and dial *#*#869434#*#*
To check settings *#*#INFO#*#*
Also look under the SIM card settings. If you've enabled either properly there should be a menu item saying "Use VoLTE" and similar.
Once enabled for me it took a few minutes for VoLTE to register. I rebooted, but don't think that was necessary. Now I make VoLTE calls (4G stays in place during the call) and I have a VoLTE icon in the status bar.
Hi,
I've bought the unlocked (Global) AT&T G8 Thinq! from Aliexpress and shipped it to Poland (EU). It seems that I can chose one of two - calls or Internet.
If I select the "2G" networks on, I can make calls and text messages, but the Internet is so slow, that it is unusable.
If I turn off the "2G" networks, Internet works fine, there is even a LTE icon, but I am unable to call and receive calls ('Mobile network unavailable' popup, when I try to call)...
There is no menu to choose network mode like 'LTE/3G/2G'...
Firmware is most up-to-date - G820UM20r.
Do you have any idea, how could I fix that?
BR,
Dominik
I'm on EE UK but the preferred network type setting doesn't appear to be present in SIM options?
It appears that some providers suck hard and don't want to allow you to switch networks. That's not a phone thing-y, it's a provider thing-y. Which means that your phone will of course still change networks, but only if the "higher" one is not available, ergo your phone will only connect to 4G, if 5G is not available - if the 5G connection is bad, that will probably cause problems for you, because your phone will probably not want to connect to 4G automatically.
I can easily switch preferred network types
Settings -> Network & Speed -> SIMs -> (scroll down, between 4G Calling & Carrier settings version) -> Preferred network type (5G, 4G, 3G, 2G).
It that's not available, your network carrier sucks. No more to say here.
I'd suggest you either switch providers, or contact your provider to see if they are willing to change this. It's definitely on their end, cuz people like me can change the settings easily.

You may be able to change preferred network type with *#*#4636#*#* dialer code.

EE (& BT Mobile) hide the menu.

Or you could just make sure Adaptive Connectivity is enabled and not worry about it.
You would have to drag me away from EE (BT Mobile) screaming and kicking given the coverage and speeds they have, to say they suck over one menu option missing is absolutely laughable.

When the Note 20 first came out a lot of carriers wouldn't let you change network type but there's an app in the play store that was working on the notes.
Force 4G/5G Only - Apps on Google Play
Lock your phone to 4G/5G mode or VoLTE network

Crashes or alternately just disappeared for me when I click on the first option "4G LTE with only one SIM". Reported the crash. Thanks, though. Maybe they'll update it.
An alternative to the dialer code is to boot into safe mode, and the preferred network type setting will appear in: Settings -> Network & internet -> SIMs between Data warning & limit and Carrier settings version (at least it does on my Google Fi Pixel 6 Pro).
Hello everyone,
on my companies area I have a really bad phone signal (LTE). How ever, I am constantly connected to my companies WIFI.
I now wonder if being connected to the WIFI will reduce battery drain due to low LTE signal?
I was hoping that the phone then only needs to search for better reception if the signal for phone calls (bot not internet) goes completely off?
Another solution would be to use Tasker to switch to my company SIM with full signal strenght (I am using dual SIM) for data/internet when on my companies area.
In any case, my private SIM will still always have bad signal but will be active for phone calls. However, my data reception will be very good (while I am still also connected to WIFI).
Just looking for the best solution in terms of battery drain.
Thanks!
VoWifi is a boon for low cellular coverage area usage while saving battery life on WIFI and still being available for phone calls. Ask your provider for specifics
Ahh thanks for that hint!
So if I enable Voice over WIFI, then my phone will stop searching for better radio signal if the WIFI signal is good enough?
Yes, in fact you can enable Airplane Mode which switches off all radios, turn on wifi radio manually to enjoy great battery life and VoWifi calls.

Hmm except that I can't seem to find the option on Android 12 to enable wifi calling :S :S
Even without VoWifi you can save battery life by manually switching to 3G or even 2G for calls while using high speed data on wifi
Your carrier must support VoWifi to be seen as an option on your device.
Here is a list of US carriers that use the newer advanced Vo technologies:
T-Mobile
– VoLTE: Yes
– VoWiFi: Yes
AT&T
– VoLTE: Yes
– VoWiFi: No
Verizon
– VoLTE: Yes
– VoWiFi: No
Sprint
– VoLTE: Yes
– VoWiFi: Yes
I am from Europe so I use a different carrier. That carrier has VoLTE and VoWiFi enabled.
How ever, it seems like the carrier also has to approve each specific devices to be allowed to use VoWiFi.
As the P6P is not being officially sold in my country, I suspect that my carrier doesn't have my device on their whitelist :/

Thank you very much. I will probably root soon and will give it a try then. Although there is an github issue open which says that the module is not support by the Pixel 5.
Just a bit annoying that I would have to apply this after every OTA but I guess it's doable
I also talked to my carrier today. They are saying that only phones that are being sold by the carrier support VoWiFi as the phones OS needs special settings that are being provided by the carrier. That is why usually the Android updates from phones bought through our carriers come later than the official google updates (due to the carrier updating the OS himself first).
On the other hand it seems like google could integrate those "special" settings right out of the box.
How ever, google seems to say the carrier has to get in touch with them and start the procedure whole the carrier says that is google who has to take care of it by them self.
Since the phone signal for my SIM is really bad on my companies area but the WIFI is very good, this should then hopefully help a lot with battery drain.
