T-Mobile wifi calling possible on unlocked S7 Edge (SM-G935U)? - Samsung Galaxy S7 Edge Questions and Answers

I have an unlocked Galaxy S7 Edge (SM-G935U). My carrier is Total Wireless (Verizon MVNO). I recently got a new office at work, and the Verizon coverage in this part of the building is terrible. I use wifi for data but cellular calling basically doesn't work at all.
I've been looking at other networks, and I'm leaning toward T-Mobile or MetroPCS, one of the reasons being they have wifi calling and the wifi at my office is plenty fast. I checked in settings to see the wifi calling option, but when I go to settings > connections > more connection settings, which is where the wifi calling setting is supposed to be, there's nothing about wifi calling.
I had a thought that maybe the wifi calling option isn't there because my current carrier doesn't support wifi calling, so I contacted Samsung support. I asked if I get a SIM from a carrier that supports wifi calling, would the wifi calling option be enabled. They said that unlocked phones don't support wifi calling at all.
This confuses me, because this thread mentions some people were able to use T-Mobile wifi calling on an unlocked S7/S7Edge. But that thread is older, so maybe for some reason wifi calling was removed from the unlocked S7 Edge with the Nougat update?
I suppose the only way to find out for sure is to get a T-Mobile or MetroPCS SIM and see what happens. But is anyone able to shed some light on if this is even worth trying? I suppose it's also worth trying out just to see if regular cellular calling on T-Mobile might be fine at my new desk, but hopefully there's some way to do wifi calling.

Unfortunately I think you need the sm-g935f to get t mobile wifi calling. Don't think it was ever achieved on the U models

I had an s7 edge from T-Mobile (SM-G935T) but I flashed the unlocked firmware essentially making it a SM-G935U and I had VoLTE and Wifi calling working with no issues. It was about a month ago, so it was on Nougat. I would expect no issues with an actual SM-G935U on T-Mobile.

Well, I answered my own question. I switched over to the T-Mobile 10 GB $50/month prepaid plan and when I changed SIMs the phone gave me a "reconfiguring your device for new SIM card" message. Wifi calling is now active.

Also, this is a list of phones that support T-Mobile wifi calling. I probably should've checked here first.

Wifi calling on freedom mobile

Recently I got an S8 and I ported over my number to freedom from fido.
I thought the wifi is available on S8 but it is not.
Does anyone know when wifi calling would be available for S8?
The S8 supports VoLTE and WiFi calling, however it's upto the Carrier to enable the feature. I'm on Rogers, with my S8 I have WiFi calling and VoLTE working. However people who have unlocked S8's on Rogers won't get WiFi calling or VoLTE because Rogers blocks it on phones not purchased directly from Rogers.
Actually Rogers does not block any phone that it is not purchased from roger's itself.
I have been with Fido for 12 years and last year I got a brand new S7 edge from the Samsung store in Sherway Gardens.
The VoLTE and Wifi calling worked out of the box.
I called Fido and I wanted to make sure to register my new IMEI and the woman on the phone told me that the IMEI is automatically registered after few days
but just in any case she did regestered it.
I kept my Fido for few days before I port my number to Freedom and the S8 I got from Freedom worked in Fido (I unlocked it)
and the VoLTE and the wifi calling. Although what I did was to change the CSC. Then I changed the CSC back to Freedom and I did
not have the option for the wifi calling.
What I have noticed is that the phones that are sold in Canada (At least the major models ) are the same and the only difference is the CSC (network customization)
code that are come preloaded.
Now Freedom is a new to VoLTE and Wifi calling so I am waiting to enable the wifi calling in S8

check this thread, Rogers will not support VoLTE and WiFi calling on phones NOT purchased directly from Rogers:
http://communityforums.rogers.com/t...-Phones-Not-Bought-in-Their-Store/td-p/397684
I don't know what the thread says but I can tell you that I have been with Fido for 12 years and last year I bought from Samsung Store a S7 and after few months an S7 edge
and on both phones VoLTE and wifi calling was working just fine.
I never had a single problem.
Also I called Fido representative and confirmed that both services were configured on my account with a problem
Also few days ago when I got my S8 from Freedom (I sim unlocked it) I put it on my Fido sim card
and VoLTE and Wifi were working again just fine

Using wi-fi calling on a G900A on T-mobile

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.

VOLTE Wifi Calling with Unlocked S10+

Hey there, I've been doing a bit of research but it has been a long while since i have done any flashing of firmware etc. I received my s10+ device today. Model number is SM-G975UZKAXAA. I am a Verizon wireless customer. When I placed this device on my account I noticed I have no access to Voice over LTE, and I also do not have any access to Wifi Calling. My question is the following. I read somewhere a couple of weeks ago that if I wanted something like this I would need to flash the original VZW Firmware which would have all the lovely bloatware etc on the device. Is there any way I can do that? I have seen firmware that has been posted but I dont seem to see anything that specifically is the VZW apps etc which should (hopefully allow VOLTE and Wifi Calling and maybe even HD Calling, if thats a thing)
I would appreciate any info anyone can provide me on this, as the only solution I can see at the moment is to return the device and start over with a VZW specific device.
Cheers~
Likewise but with a T-Mobile firmware for me
Unlocked US version here with Verizon and wifi calling and volte working out of the box.
You may want to call Verizon to see if they need to provision it for your account.

Hey guys, just wanted to check in with you (or anyone else who has wifi calling on unlocked Verizon). It is 100% working? It's the only reason I got the carrier version. Should I cancel and order the unlocked?

Yes, it works with my unlocked S10+ on Verizon. It surprised the heck out of me as I too have the unlocked Note9, but no wifi calling.
What about on AT&T? Can anyone say if they can at least get VOLTE? WiFi calling would be the icing on the cake. Thank you

Wifi calling worked on my unlocked S10 out of the box on T-Mobile. I'll try and check on VoLTE later but I get **** reception near work.
Can you explain how you enabled WiFi calling on unlocked version, on Verizon? I can't find a way to do it. What about HD Voice? My real problem is that data does not work while on a call, using my unlocked, on Verizon. Is there a way to get that working?
I have unlocked S10+ on VZW. I get LTE+ which is VoLTE, data works while on a call.

I don't think that is right. LTE+ and VoLTE are different things. As well as data while on a call.
VoLTE means your call is being transmitted over LTE. I'm pretty sure you can use data while on a call WITHOUT VoLTE.

How do you test if VoLTE is working? Do you get an Icon for it?
I tested WiFi calling by going into airplane mode, turning Wifi on, and making a call and it worked. But didn't get a special icon for it.
For those basing your decision to buy unlocked/international vs branded, be warned. I can only speak for Att, but I spent about 2 hours arguing with their level 2 tech department and here's what I have learned. If you have a sim that is provisioned on a branded phone and then put the sim into an unlocked/international phone, you will be able to use volte, wi-fi calling, etc., but only until the carrier pings your imei for a periodical check, once that happens, those features disappear. Also, on Android Pie, the Enhanced LTE Services tab under Mobile Data has been removed as it is turned on by default, also confirmed with ATT. The only way to manually check is to toggle wifi calling on and see if it works. Anyway, just trying to help as I have gone to a branded phone for the first time in 6 years because the reception and enhanced features are more important than rooting to me.
I was able to get wifi and volte working on my unlocked s10 by putting sim into verizon phone, letting network recognize it, enabling advanced calling and such on that device and then taking the sim out and putting it back in my new unlocked s10. The option for volte appears in settings-connections-mobile networks.
VoLTE works on tmobile, not that anyone should be surprised. That has been the case for the S8 thru N9. Now... I noticed that Samsung removed the VoLTE toggle from settings.

Correct, no VoLTE setting on my unlocked S10e, but it is on by default it seems

Using what I learned in this thread, I called Verizon and talked to Level2 support. They tried to get everything working and could not - but this was when I had the new SIM installed, provided by Samsung when I got my S10+.
So because others here spoke of their 'other' SIM, I suggested we try that - so I plugged in the SIM from my S8 and asked them to reprovision everything. They did... and....Now everything that didn't work ... WORKS.
So I have an Unlocked S10+ on Verizon that has (among other things):
- Wifi Calling
- Real Time Text
- VoLTE ("HD Voice") (Which means data now works while I'm on a phone call)
- Visual Voicemail
So it seems the Samsung SIM was part of the problem, and they are reporting this to Samsung. The tech support person told me others have reported similar issues and they will get with Samsung to figure out what the issue is.
Hopefully this helps some others as well!

Wifi calling on Samsung S8 (G950U) with AT&T

I recently got an AT&T prepaid sim card and I flashed my Canadian W model to G950U (AT&T) branded firmware. I am trying to activate the wifi calling and I get an error APP0008. I called AT&T and they keep telling me that the phone is not an original AT&T and wifi calling is not supported on non AT&T phones.
Has anyone seen this error and how did you resolved it.
Wifi Calling is exclusive for PostPaid accounts. I have Prepaid and they do not activate it for me.
Finally I was able to enable wifi calling on my S8 and Note 9. Both phones have been flashed with the ATT firmware. I have a prepaid account with ATT and I use Canadian models S8 and Note 9.
Of course I cross flashed them with the U firmware and my account has been provisioned for call waiting
Let me describe the problem here.
When I try to enable wifi calling I get an error message APP0008. When I try to read the network settings for call forward and call waiting Samsung says Something went wrong. There is a sim error or network error.
So for some reason Samsung phones can not read the settings from the network. Some people report that if they restrict the phone in 3G mode only are able to read the settings but for my did not make any difference.
My solution was to put my card on an iphone and try to see the call forward settings and enable/disable the call waiting. I got an error as well.
After that I put my sim card to my Samsung phones and suddenly the phones were able to read the network settings for call waiting, call fording.
At the end I went and enable the wifi calling and the phone brought up the ATT page for wifi calling and everything was ok.
The question here is what the Iphone is doing to the sim card/or network and then samsung is able to read the settings and enable the wifi calling?
For people that have problems enabling wifi calling on a ATT firmware (U models) and on Samsung phones and get the APP0008 error try the above

Wifi calling not available

I have a S10+ that was bought from US Cellular that I am now using on Straight Talk with a TMobile sim. I had Wifi calling working just fine before I switched to the new Beta update. After switching back to Android 9 it now says "This is currently unavailable under the call settings for Wifi calling. I am at a loss. I live in an area were the cellular signal is spotty at best and need Wifi calling to work.
Anyone have any ideas?
Thanks

AT&T doesn't like unlocked phones so it's possible the option isn't showing up because of that. Many AT&T customers with unlocked phones have reported that they needed to contact AT&T customer service to get WiFi Calling or Volte working.
