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?
I bought a SM-N960U1 unbranded US unlocked model, and I immediately updated it to Android 9. THEN I inserted my T-Mobile sim, and I have wifi calling. I did all of this a few weeks ago, and I never really questioned it all until today.
I'm posting this now because I read that people cannot get wifi calling to work on their unbranded model unless they flash carrier firmware.
And this is what I've found. When I make a call while connected to wifi, I see the little wifi symbol on my phone symbol, as if the call is a wifi call. I have a toggle for wifi calling, which works! If I toggle wifi calling off and make the call again, no wifi symbol on the phone symbol. When I look in settings > connections, I do NOT have items to set wifi calling and VoLTE. However, I can search settings for wifi calling and I will find the Samsung 'Wi-Fi Calling' app (com.sec.unifiedwfc 6.0.33.47) RUNNING!
So, it seems I have wifi calling working on T-Mobile, with just the Samsung stock firmware and not the carrier firmware. Which is great! No carrier bloat.
I just tested my wifi calling by starting a wifi call and then walking out of wifi range, and it definitely works! At the edge of wifi range, the call broke up, handed over to the cell tower, and became noticeably less clear. I'm stoked to have wifi calling without carrier bloat.
I might investigate further if there are some settings I can toggle over adb (wifi preferred, etc)
It depends on the carrier. T-Mobile does support all of its services, including WiFi calling, on the N960U1. Some other carriers do not. Always check with your carrier before buying an unbranded phone.
I also just discovered that toggle button text is CLICKABLE, and I can access Wi-Fi Calling SETTINGS when I tap on the wifi calling toggle's text, which gives me the option to turn on/off wifi calling, wifi/cell preferred.
So I have Wi-Fi Callng, can change settings, all in the stock non-branded firmware of the SM-N960U1.
AWESOME!
Hey Everyone,
Have any of you managed to get WiFi Calling working on this device without root?
I'm considering upgrading to this phone from my flawless Redmi Note 7.
However, the only feature I would need confirmation works is the WiFi calling.
Is this working on this device without root?
If yes, does anyone know if WiFi calling can work on TMobile?
I am using WiFi calling and VoLTE on T-Mobile in the US. I followed the directions on the thread below. When I ran the *#*#*****#*#* code, it gives a message about VoWifi/LTE carrier check enabled or disabled. After making sure the APN was correct (especially the APN Type), enter the code until it says that the VoWiFi/LTE check is DISABLED. Once it is disabled, you should see the option to enable WiFi calling and VoLTE in the SIM card settings. It will then show the status during calls whether it is a WiFi call or VoLTE call. It may require a reboot after the codes are entered.

Thanks Man!
I appreciate your prompt and thorough response.
I haven't been able to get WiFi calling working on my Redmi Note 7 and tried just about everything. (Outside of root)
Now that you've said that I have hope I'll get WiFi calling working on the Mi Lite 9 and think I may get one!
May I ask if you're rooted?
Also which firmware do you have?
Hi folks...
I set up my new Zenfone 8 to use as a WiFi hotspot. It doesn't work at all (I tried connecting with my computer, and with another phone, and I get no internet connectivity).
However, if I use my work's Samsung S20 or my old Sony XPeria XZ2 Compact, it works fine.
My work's on Verizon, my personal devices on AT&T.
The only things I can think are either:
1. There's a problem with the Zenfone 8 for use as a hotspot
2. AT&T is blocking that phone for use as a hotspot (tho' I don't know why they'd allow it on my XZ2 Compact - both are unlocked phones I didn't buy from AT&T)
Any ideas what might be going on here?

I dont know if this is what happened to you, but I have to changed my hotspot password to WPA2 instead of using WPA3

Yeah, I have it set up for WPA3 - I'll try WPA2 and see if it works!

Ok, just tried it. Also tried various other changes to WiFi Tethering settings.
Unfortunately, nothing ended up working.
I'll do my experiment using my old phone, and then, at worst, pay AT&T extra for the priviledge. :-(

Turn "Allowed devices only" off, if it's on - I needed net on my other phone because of a LAN network outage, and I just couldn't properly connect when this option was on.

Hi, Try following actions:
1. On all of your devices forget your hotspot network first
2. Setup hotspot without password first
3. Try to connect and test the connection
4. Once connection success, disconnect then change the security to WPA 2
5. Forget hotspot network again
6. Reconnect with WPA2 password
On my case somehow all of my devices need to forgot hotspot and re-setup hotspot. I don't know why but before forget and re-setup all my devices could connect but unable to browse internet
I use hotspot two days ago , i don't have time when i use it to find how connect with security so i disable security and it work fine
@hadi_rena @mick711 Unfortunately, none of these worked; I tried connecting to the Zenfone 8 from multiple devices, and though they connected to the hotspot, there was no internet connectivity. I'm presuming AT&T is blocking it and want me to give them more money to allow it.
Hey, Tim and perhaps others having this issue. I wanted to share my experience with being able to connect to the wifi hotspot on my Zenfone 8 but not having internet connectivity. In my case, my carrier is Consumer Cellular on the AT&T network.
Upon receiving my new Zenfone, I lost the wifi hotspot capability. I have heard that Consumer Cellular, and other carriers, require you to request that the wifi hotspot feature be enabled. For me, this wasn't the issue, as the feature worked fine when I switched my sim card back to my prior phone, a Sony Xperia XZ1. With the sim card in the Sony, I dug into the APN settings and discovered a few differences when compared to the default Consumer Cellular APN settings on the Zenfone. I first attempted to add a new APN to try out different settings on the Zenfone, but was puzzled why after creating a new APN, editing its settings, and tapping save, the APN was not saved to the APN list. I'm guessing that this is a Consumer Cellular block. Then, I decided to edit an existing APN, I believe it was called Tracfone. The settings which seem to enable the wifi hotspot function are the MVNO type and MVNO values. Another strange quirk is that when you edit these values and save the APN, all the other saved APNs disappear from the list. If you then change the MVNO values back and save the custom APN, the other APNs reappear, perhaps another Consumer Cellular effect? At first, I was concerned that changing these settings might interfere with or disable some network-related functionality, requiring a quick APN edit every time I wanted to use the wifi hotspot option, but I have not noticed any issues. I realize that these MVNO settings are related to carriers like Consumer Cellular that utilize the networks of other major carriers: AT&T, T-Mobile, Verizon, etc., so this fix might not work for everyone. I thought I would share it anyway. I have attached screenshots of my APN settings for reference.

Thanks for this! How did you know which values to use for MVNO Type and MVNO Value? I have AT&T, and those values are both unset for the AT&T access point.

I just tried the two settings that worked in my older Xperia XZ1. I've attached photos of the settings from that phone. Both configurations allow for wifi hotspot on my Zenfone 8, but I have only used the GID for any length of time. It seems that when you choose the MVNO type, it autofills the MVNO value, at least it does for me. I don't fully understand what these settings mean other than that they relate somehow to resellers. I just know that changing them allowed the wifi hotspot to work again for me. Someone else here would probably have a better explanation for it.
Edit: I found the following link that explains some of the MVNO settings.

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

Same access issue here too.
Wish you luck.
