So, I was an idiot and didn't activate advanced calling on my Verizon S5 before switching to T-Mobile. Now when I go into settings and advanced calling, it tells me I need to activate Advanced Calling Features to enable them. When I click activate, it gives me an error every time.
I stupidly thought I could just put in my old sim card and try, but that didn't work either.
Is there any way that I can enable advanced calling and WiFi calling on my Verizon S5 without reconnecting to the Verizon Network?
Root: Yes
Carrier: Verizon
Network: MetroPCS
Problem: Wi-Fi calling
Did you do any research: yes
Description: Verizon likes to disable Wi-Fi calling and other things we live like "advanced calling." Is there a work around for SM-G930V to enable Wi-Fi calling for the people who don't have a Verizon account?
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.
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.

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
