I have Oneplus 7t pro and because I have poor carrier signal in my home I have enabled wifi calling, vowifi, volte.
I see the VOWIFI icon in my oneplus but when I receive or make a call, in most cases the phone doesnt use it.
The icon is lost and the call quality is bad.
Is there a way to Force the phone to always prefer vowifi?

Hi,
I am using Mate 20 Pro (LYA-L29) in US and the firmware is 232. I am pretty sure that my carrier (not U.S. carrier) supports VoWifi and I used it on this Mate 20 Pro before while I was not in U.S. After I moved to U.S., I also updated the firmware and the Wifi Calling option has gone since then. To double check what is the cause, I inserted this SIM card into an iPhone and Wifi calling was available and worked well. Therefore, I think it is a problem of this phone.
Does anyone encounter a similar problem?
Thanks!
Different networks operate WiFi calling in slightly different ways. I know that my Mate 9 didn't support WiFi calling in the US but has done in other places without issue.

I don't quite understand why wifi calling depends on the physical place. Say I set the phone to airplane mode and connect the phone to different wifi routers in different places. The wifi standard is always the same and the phone may not be able to tell where it is.
VoWiFi and VoLTE (WiFi and 4G calling) are network and handset dependant. If a particular network hasn't authorised a particular handset, or if that handset doesn't have the specific settings needed for a particular network; then VoWiFi and / or VoLTE won't work.
I installed "Network Cell Info" to check the status of Wifi Calling and the availability of Wifi Calling is No. I notice that the devices prior to mate 20 pro have a secret menu and there is a switch to turn on the availability of Wifi calling. However, the secret menu code does not work anymore in my mate 20 pro.
This is so fvcked that despite my carrier (from which I GOT THE DAMN PHONE) supporting VoWiFI (I had it working on my S7Edge before this) and despite VoLTE working on my Mate 20P, they just won't enable it on Mate 20P.
Guess what...it DOES work on P20/30 Pro, from day 1. Go figure.
Also...got a SIM from a different carrier...bam, VoWiFi working on mate 20P.
This is madness....I'm running out of hair to pull.
PS I went as far as installing Nova launcher so I can create a widget to ENABLE VoWiFi (which normally does not show up in the Settings) but of course it does not do anything because the carrier did not enable it for the phone.
i have same problem in Israel carier
i have the volte switch but its not working.
other carier its worked automatically but their internet i cant watch youtube at 1080p

My situation is exactly the same. I have a switch for VoLTE but not for VoWifi. I also tried Nova launcher, but it did not work.
The strange thing is that the sim + mate 20 pro works in one place, but not in the US.
So i got my Mi 8 Pro yesterday (Global Version). The one feature I cannot seem to activate is Wifi Calling, I have done both the *#*#86583#*#* (voLTE) and *#*#869434#*#* (voWIFI), both options are enabled in *#*#4636#*#* and when i go into my sim settings both VoLTE and Wifi Calling are enabled
voLTE shows the symbol in my task bar however wifi calling never seems to enable? Is there some other setting I am missing or do I need to get EE to disable and re-enable it on my account since I've swapped phones? It's vital for me as I work in a lot of places without cell reception so i rely on wifi calling.
Any help is appreciated

Hello, my friend is also like you, he is the development version of WiFi can not be used but the stable version of the MIUI system can be used. You can try to re-wire the stable version of the MIUI system, I wish you good luck.
Carrier supports both VoLTE and VoWIFI. Global Pocophone f1 should also support them. However, carrier check needs to be disabled in following way:
VoLTE *#*#86583#*#*
VoWIFI *#*#869434#*#*
Enable in settings
However, despite doing above, VoLTE and VoWIFI doesn't work (VoWIFI works very rarely. VoLTE never).
*Strange issue:
If this same sim is inserted in a recent Samsung phone (A50), then taken out and put back into Pocophone, then suddenly VoLTE and VoWIFI work properly!!
(However, this had to be repeated after installing a new ROM)
Anyone shine some light why this strange thing happens? Why does a Samsung phone enable VoLTE and VoWIFI on pocophone f1?
Had the same issue
Hi, I also had the same issue. I followed your tips with the *#*# numbers and now the option to enable VoWIFI and VoLTE are there in the sim card settings. But it doesn't function properly though. Tried to swap it onto an iPhone 6 and swap it back to my pocophone. Still doesn't work (no VoLTE nor VoWIFI symbols appear). Going through MIUI Hidden Settings, found out that option for all those things are greyed out with no means to enable them.
Just to let you know the issue on my particular device.:good:
Iphone 6 is an old phone came out in 2014, I doubt it has volte/vowifi. I Tried on a XZ1 which was from 2017 but didn't work either.
I suggest u try it with a newer phone. I tried on A50 which came out in 2019 and it worked.
iPhone 6 does support both VoWIFI and VoLTE, there are options to enable this, and my carrier supports it too.
you need to ensure the iphone is turned on and connected to network while the poco sim is inserted into it. turn on volte and vowifi on the iphone to see if they are working.
sometimes the symbol for vowifi/volte maynot show in status bar even if they're working. best way to check for volte is to see if 4g symbol remains in statusbar after call is connected.
I've done it many times on miui (after flash roms) and work everytime.
Hello
I'm having this issue, I cannot enable volte. Vowifi is enabled and working fine. I have tried pretty much everything, the dial numbers etc.
I'm running stock miui global 12.2.7.
I'm posting a couple of screenshots, one is from the dial *#*#4636#*#* phone information and the other from network settings where volte toggle is nowhere to be found.
If you get 4G you have VOLTE. If you get 4G+ you have VOLTE-E. If your connection drops back to 3G in calls its because of either calling another network or the other phone is in a 3G area.

Hello and thanks for the reply.
The area I live in has mostly 5G coverage and when not available, 4G+ and 4G.
All I'm saying is I can't enable it as you can see in the screenshots. There's no option in the settings, and the option is unclickable in *#*#4636#*#* menu.
The Volte sign never shows in the status bar, and in the call history, I don't get the HD sign next to the names, only the WiFi - when the call is on VoWiFi. - which is logic, sign I can't get to turn it on.
Thanks in advance.
Hello,
i have the problem that VoWifi is interrupting calls.
Looks like my LTE signal is not stable enough so VoWifi is jumping in and then the LTE signal is strong enough which kills VoWifi.
So its like ping pong, VoWifi on -> VoWifi off and so on.
Does anyone has this issue too?
Is there a fix to keep/use VoWifi everytime when connected to wifi?
Its very disappointing on phone calls when the voice is interrupted.
Do you by chance have this option to make WiFi preferred?
