I am on Android 7.0. See software specs in attached screenshot. Three UK turned on wifi called end of January. My phone is unlocked and bought from Samsung. I don't seem to have the WiFi calling option. I have already checked that you don't need a phone bought from three, it will work with any s7 Edge.
Anyone have wifi calling working with any network on a non carrier phone? I don't see any options for it anywhere either.
Launch the phone app (I.e. The green phone icon), tap the settings option on the top right. For me it's an option just under vibrate.
I'm on EE with a phone that came direct from Samsung.

You should see what CSC/PDA the stock Three UK S7 Edge comes with, I think it is this one https://samsung-firmware.org/download/Galaxy S7/81c4/HTS/G930FXXU1DQB7/G930FHTS1DQA4/ but you should confirm. Then flash it with Odin. It won't trip Knox or anything. You can find out how to do that here on XDA.

I did confirm with three today and have found it elsewhere on the Internet that it doesn't need three own branded firmware. So I don't really want to install it. I was part of the 7.0 beta, I wonder if that has caused issues.
Yes I'm on the same build version. I was also on the 7 beta and the only difficulty I had was locating the WiFi calling option as it used to be located through the main settings.
Do you have to opt in for WiFi calling on Three? I think I may have with EE.

On the three website it says you just sneed a Compatible phone and the latest update. That's it. I also spoke to three who Confirmed this and then went on to say I should Contact Samsung......
Any joy with three wi fi calling s7 edge
I have updated my unlocked s7 edge as suggested by three, but no wi fi calling available, I have to walk to end of road on holiday cottage could do with a fix. Three in touch no longer works either. Did you get a solution from Samsung?
Wi-Fi Calling works only on H3G Firmware
After few nights of flashing various CSC ROMs, I can confirm that Wi-Fi calling and HD Calling on Three UK appears on H3G firmware only and it works like it should.
Here are few notes after flashing:
XEU - No Wi-Fi calling option, VoLTE icon intermittent, dropping calls after few min if started calling on 4G, keeps switching back to 3G to initiate a voice call.
BTU - No Wi-Fi Calling option, VoLTE icon appears and seems OK when calling over 4G, however no HD voice.
H3G - Wi-Fi Calling option appears in Call Settings and it works! However no VoLTE icon but for sure it makes voice calls over 4G as it initiate a voice call much faster and the radio doesn't switch back to 3G, also the HD icon appears when making a phone call to compatible service number or another phone which supports HD voice - call is sharp crystal clear like on Skype or Messenger etc.
Conclusion: To get all stuff enabled Wi-Fi Calling + VoLTE + HD Voice you need to get your phone directly from Three or flash H3G firmware to your current phone.
H3G firmware luckily hasn't got too much of a bloatware, it can be easily uninstalled or disabled :laugh:
Please hit thumbs up for me :good:

I found exactly the same when I tested roms, you need the network rom to get wificalling.
I know this is an old thread but still relevant today.
I found pretty much the same thing. WiFi Calling and VoLTE on EE needs the EVR firmware (but I think it may work on BTU as well with Android 8)
3 does require the HG3 firmware
Without the correct match of firmware the option to enable WFC does not appear in phone/settings.
Others like O2 and Voda probably require their own firmware as well.
But what is really weird is if you get for example, an iPhone 6S and put a 3 card in it...WFC just works and the same with EE. No special firmware. Maybe Apple know something we don't
Do you see the WiFI Calling option in Phone Settings with Three / H3G UK firmware on a phone that works with WiFi calling? I can't see any reference to that option on the Three help pages. If so, any chance of a screenshot?
Thanks
I am in similar situation with S7 Edge which currently doesn't have an option for wifi calling. I moved from O2 to Three recently. O2 wifi calling worked and the option was there. It doesn't have the option on Three.
Does anybody know which firmware to flash which will enable this option? I've downloaded both the BTU version and H3G version for the UK. Can anyone please confirm if either of these will enable wifi calling option?
Many Thanks.

I think you have a better chance with the Three firmware, but AFAIK, the issue is that Android phones are coded to a carrier. This doesn't seem to matter with VOLTE but for some reason VOWiFi is an issue. If anyone knows how to get around this, I'd be happy to know too.

Thanks for the reply. I thought the Three firmware would be better but I was hoping someone has tried this and actually got it working. Seems odd that the phones sold direct by Three have this by default but it seems almost impossible to enable if the phone was bought elsewhere. That's why I'm wondering if the H3G firmware I found on Sammobile.com has the feature or not.

Some posts earlier in this thread say they have WiFi calling working after flashing the Three firmware. This does not work on my LG G5, but you may be luckier with a Samsung phone.

I have a couple of Samsung Galaxy S7 edge duos dual-SIM phones in which I have SIMs from different network operators or MVNOs. One is usually a Three PAYG SIM and the other is a Virgin Mobile (now VMO2) contract SIM or other MVNO PAYG SIM.
I am in a poor signal area for all of the networks despite being in a built-up urban area of Aylesbury. I currently rely on a Home Signal unit from Three to cover that network but would prefer to use Wi-Fi Calling for all networks.
What do I do about the secondary network?
Which ROM firmware should I be using?
Why doesn't all firmware enable Wi-Fi Calling and VoLTE for any network?
Ofcom have banned phones being locked to a network from December 2021 but the ban does not seem to cover these issues which are tantamount to locking a device to a network.
Ofcom needs to address these issues before the end of 2021 when some networks will have withdrawn support for their Home Signal type equipment and even 3G fallback for voice calls in 4G/5G coverage areas.
I just now switched from AT&T to T-mobile because I finally got sick of AT&T for various reasons including very high prices. The network lock is removed. How can I get wi-fi calling to work on this phone? When I try to enable it, I get "To enable this service you must confirm your emergency address.". Then I see "Wi-Fi calling lets you make and receive calls over Wi-Fi with your AT&T account. When you use Wi-Fi Calling, information about the country where the Wi-Fi connection is made will be sent to your carrier. Learn more about Wi-Fi Calling.". The last two words are a link to https://m.att.com/shopmobile/wireless/features/wifi-calling.html?referrer=. It seems there's a hangup of AT&T versus T-mobile. What should I be doing to get this working?
In case anyone is wondering, this particular phone is being used because it must be kept unrooted. I have a G900T that has been rooted.
Hello,
I have got the odd situation with the SM-G950FD (Singapore non-branded XSP CSC) living in the UK and using the Vodafone UK network whereby I am unable to make VoLTE phone calls although I have got the VoLTE function enabled. I first thought it was because of the network, however I came to notice that I am able to use VoLTE to make phone calls when I make them from my car over Bluetooth. It is of course the same mobile phone, and I can confirm VoLTE use as the display continues to show 4G+ or 4G whilst on the phone instead of jumping to H+ or H.
It seems as if phone calls over Bluetooth must be triggering a different call initiation routine compared to making a phone call using the dialler on the phone itself. Has anyone encountered this before and has anyone an explanation for this? How can I fix this so that I can VoLTE phone calls from the phone directly as well?
Thanks
Wolfgang
I currently have the international variant of one plus 8 pro. I live in NYC where we also have 5g (finally!) On the T-Mobile network. I turn on the wifi calling and for some reason when I make a phone call, lte + wifi calling on, the other person can head me but I can't hear them. Then when I turn off the wifi the call drops. If I make the call again the other person can then hear me and I can hear them. Help?
Phone is rooted if any fixes exist that I need to push.

This is interesting, I have the same phone not rooted, on Verizon. I don't have the Volte switch and the Wifi calling switch will not stay on. Plus the Calling preference will not lock on, stays off
Mine locks, stays on I can even make calls but can't hear the other person
Im having the same issue. First call i hear nothing. But second call is ok.
I got a new sim card today. Let's see if that makes a difference. Some calls go through okay some don't. Really random

OP has to work on this, ,my Pixel 2xl could make great calls even in Airplane mode
Just talked to a Verizon agent-
Verizon Agent-
You said you have an One Plus in which you are facing the issue of wifi calling.I am apologize for the inconvenience as this feature is not supported in your device.
I have an unlocked and rooted H910. It is my backup phone and I want to get it to work with a T-mobile mvno sim for wifi calling.
Calls and data work with the sim and the wifi calling toggle is there - but when I switch it on it spins and spins for a bit and then says failed.
I tried 10r stock and Alpha-Omega and they both do the same fail when the toggle is switched on.
I would download another ROM but am I chasing something that just will never work? Or is there a app or service that I can delete that ATT is checking for ATT sim before enabling Wifi calling?
Any tips are appreciated.
Thanks
Not sure if it matters to anyone - but I couldn't find an answer to this. I tried freezing a handful of ATT apps with Titanium Backup. I probably could have wrestled with that a little longer but I gave up. I now have an ATT MVNO sim and it all works fine. So I can confirm that the LG V20 works with wifi calling and VOLTE calling without much issue. (I did have to ask the provider to enable WiFi calling on their end - they made me confirm my 911 emergency address but then it just worked 10 mins later with a reboot)
So - if someone figures this out I am still interested in the answer!
Thanks for looking.
