WiFi Calling Issues - Huawei P20 Pro Questions & Answers

Hey guys, so just curious, is there a way to force WiFi calling? My signal sucks in my house but my WiFi is awesome. Supposedly the device will prefer mobile signal if it is strong enough, but you can't physically choose WiFi calling to be default.
If anyone knows anything, let me know. I'm on EE.

when at home if you want wifi calling to kick in instead of celluar, do the following but it is a pain to remember to do it each time
Turn on Airplane mode
Turn on Wifi
Turn on Bluetooth (if you use bluetooth)
when you leave house, just turn off airplane mode

You can set it to prefer WiFi instead of mobile network, I don't know if it really works, my p20 pro is choosing WiFi always, even if both of signals are 100%

have wifi calling enabled, but if I don't want it to keep switching to cellular while at home, i have to switch to airplane mode, then re-enable both wifi and bluetooth. it then works, but have to remember to keep switching
you may not see wifi calling in the notification area, but when you make a call you will get the wifi notice showing

does it say wifi calling?
Has your provider allowed wifi calling on the device?
Also make sure you have enabled the option in the network settings and check under the default dialer wifi calling is enabled

do you still have the 3 sim? if not are you able to get one for testing?
I've attached screenshot showing the wifi calling option on the phone with Three sim installed

Call carrier support / Check firewall
I had to call vodafone. After some time they decided to disable wifi calling feature for my account for a couple of minutes and re-enabled it. That worked for me. My phone instantly logged into wifi calling again.
Also make sure that outbound connections to port 500/4500 are not being blocked by any firewall/router.

How do you set Wifi to be preferred instead of cellular?

May update enabled WiFi calling on my SM-N950F/DS (T-Mobile)

I have an international (gold) unlocked dual SIM and I thought I was hallucinating today when my phone got the May Android update and suddenly there was an option for Wi-Fi calling in Phone settings. I didn't think it would work but it definitely is at least on T-Mobile as I see "T-Mobile WiFi Calling" when I pull down the notification shade and calls work in airplane mode (with WiFi on).
Super stoked as this definitely didn't work before. Anyone else see this?
Why didn't wifi call work before?
I have a n950f and a German t-mobile sim
Wifi calling always worked

Different device than my SM-N950F/DS. Samsung didn't enable WiFi calling in settings in the dial SIM model until now that is.
Good to know, thanks!
after updates it doesn't show on my call settings. did you do anything different?

When I'm on WiFi, I can't receive calls

Hello, I've only just finally figured out that while my unlocked pixel 4 xl connected to wifi, i cant receive calls, I can receive while i am using the phone with WIFI, but once i leave the phone go to sleep and connected to wifi, then my phone can not receive the calls and unreachable.
I have tried to change the network mode to 3G while i am connected to wifi, and it seems solved the issue.
While i am not connected to wifi (LTE) i have no issues at all.
I have unlocked Pixel 4 XL with Jan update (latest build) rooted through Madisk, stock kernals and everything
is there any solution to this? I've searched through forums and this subreddit but have yet to find an answer. Any help would be appreciated.
Maybe try turning off wifi calling if it's enabled?

Sounds like your phone is trying to make a call over Wi-Fi but your carrier (or SIM) may not support Wi-Fi calling. Where are you located and which carrier? Using the dialer, use the following code to check your provisioned status: *#*#4636#*#* If Wi-Fi calling is toggled OFF and you cannot change the setting (grayed our) then it will not work. Ask your carrier directly if they support it.
I have tested more to find out where the issue is happening, i connected to other wifis , and the issue was not reported, the issue the only in my apartment, and only when i am connected to lte, on 3g no issue, and once i leave my apartment, i can receive calls on lte normal, this strange, i was having the original pixel with no issues such, and my wife having iPhone and doesn't have this issue,i have tried her sim card (from the same provider) and the same issue
Now when i go home, i have to switch the network mode to 3g to be able to receive calls, otherwise it will show out of coverage.
I spoke with network provider, and they told this issue we with the phone, and its ture, since inwas using the same network in my original pixel, and the issue was never happened
Please help to advise.
Thanks

Turn off wifi calling on your phone. I had a similar problem with my unlocked pixel 4xl on Verizon and that solved the problem
I don't have wifi calling option enabled under mobile settings, my operator doesn't support wifi calling.

What is the provisioning status of Wi-Fi calling in the phone diagnostic menu ( *#*#4636#*#* ). Is the toggle on or off? Is it grayed out?

What country do you live in, and which carrier do you use?
I would do a network reset in settings under the reset menu. If that doesn't work, backup and do a FDR from recovery.

Call your network provider and ask for the settings to be pushed to your phone.
They can't for some odd reason. maybe they're clueless

Volte/WiFi calling

Hi, guys.
Just wondering if any of you have working VOLTE/WIFI calling on your Pixel 5.
I'm on Vodafone UK and none of these are working, I don't get the options for the two in Network settings.
Apparently, they are not provisioned ATM.
Have you had more luck with your operators?

all working for me on 3
Yeah, I had a feeling going with Vodafone is a mistake...
Working here with O2. They have a guide on the Vodafone website for the Pixel 4 so can't see why it doesn't work with the 5. https://deviceguides.vodafone.co.uk...ress the phone icon.&text=Press Wi-Fi calling.
Well, it's Vodafone. Apparently one of their geniuses has to add a line of code somewhere..
Anyway, the guide for P4 asks for activation from within the phone app's settings and the Wifi calling/Volte settings are missing from there on the Pixel 5.

No VoLTE, tried it whilst out and about and the call quality was terrible after being used to it for so long.
I'm on iD mobile who use Three. I can see that volte and wifi calling have been provisioned and i have the option for turning wifi calling on but can't see an option for turning volte on.

It seems it's different for every operator, I can only suggest to give ID a phone call..
I'm on 3, have no issues at all
Wifi Calling
works on my P5, also a 3 user
option is found under Settings, Network and Internet, Mobile Network, Advanced, Wi-Fi Calling
I'm on Vodafone and I don't have settings for WiFi calling either. Funnily enough when I got text message from Vodafone to download internet settings they didn't even have the pixel 4a/ 4a 5g or 5 on there.. so that's probably why people on Vodafone can't enable it because Vodafone themselves haven't added the phones on for WiFi calling

Check out this thread on Vodafone forum, will try it myself and see if it works

Okay so update for Vodafone users, I got it working.
Following the second link above, 1. Go into Vodafone app and turn off WiFi calling, restart phone. 2. Go back into Vodafone app and turn back on WiFi calling (wait for 3/5 minutes and then restart phone again (you should receive a text from Vodafone saying it's enabled on your account). 3. Go to call app > settings> calls>WiFi calling>enable.
It also shows on networking settings in advanced now too.
Now I'm connected to WiFi calling, hope this helps Vodafone users

It works for me now. Just try the following:
On MyVodafone app, disable wifi calling and immediately restart the phone. Then enable it again and immediately restart the phone. The Wifi calling settings should appear on Settings/Network and Internet/Mobile network (Vodafone)/Advanced.
At least they have in my case.

What an arse i am, turns out the other caller was using their phone on speakerphone, made a few calls since and VoLTE is working just fine on BT Mobile.
Neither is working for me as well, but was working fine on my old phone.
What I noticed on my device is that it came from Google with the "KDDI only" build on it(see https://forum.xda-developers.com/pixel-5/help/kddi-variant-t4178033), which I suspect might be related to the issue.

Question Not seeing Network Preference under Enable Wifi Calling Tmobile USA

Hello
I just got this phone and set it up. Its a Global version 13.0.4 SKDMIXM.
I am on TMoblie USA - the phone is working great on LTE and 5G .
I am not able to see the Network preference under wifi calling where is can select Prefered Wifi Calling.
It appears that its running on default Prefered Cellular - because I can only see the VoLTE symbol on top.
Can someone help me in fixing this configuration to select Prefered Wifi Calling ? TIA

Hello, I'm using a 11T Pro Dual SIM India model with India SIM in Slot 1 and TMO SIM in Slot 2.
I have not found the specific setting to make Wifi Calling "Preferred" but, my phone does indicate Vo WiFi even when I have Wifi connected and Mobile Data turned on too once Wifi Calling is enabled as below.
Apparently the Voice Over WiFi Settings (at least here on my phone) only show up for SIM 1, does not show for SIM 2.
Attached are sample screenshots where the Settings are under SIM 1.
Steps to get there-
Settings > SIM cards & mobile networks > Click on SIM 1
All the way down, last Setting is "Wi-Fi Calls" to enable "Make calls using Wi-Fi".
Hope this helps.

Operators can disable this menu if they want to lock you onto Wifi preferred or cellular preferred. Does this only happen with this phone or does it also happen with the SIM in another Android phone?

There's a possibility of TMO-US not supporting WiFi calling on the Xiaomi 11T (Global), perhaps.
Although, I have been using various Unlocked phones (Nokia & Samsung) on TMO-US for the past few years & have practically never had issues with WiFi calling on any. Shall have to test it once I'm back. Won't be for some time.
Is your phone on the latest firmware? Try updating it to check if there's a new update available
which hopefully can solve your issue.
Couple of options to test, in case you have not already tested them-
a) leave WiFi Calling Enabled then disable the VoLTE feature and check if WiFi calling works?
b) disable Mobile Data, WiFi Calling enabled with WiFi connected and check if WiFi Calling works.
c) some users have had to ensure their E911 address is correctly in place on the TMO account too.

I had a working One Plus 6 - so I know TMO has VoWifi - I use it a lot due to poor reception at home .
The current workaround to force VoWIFI is
Turn On Airplane MOde
Turn ON WiFi only
then it works in VOWIFI with out any issues
I know I am missing a menu Item that can toggle this setting . I would prefer having that setting but its not a breaker for now . The phone works with all the Network features of TMO , LTE , 4G , 5G etc . No visual voicemail thats all.
Thanks

Thanks - this code is what got me to where I am now . I think from other articles - the mbn config may require some tweaking - but it refuses to give me access to it when i use *#*#663368378#*#*
Same access issue here too.
Wish you luck.
Pinging to see if there is a soln. in future.
