The Wi-Fi Calling is working but sometimes it will say service disable and sometimes T-Mobile just depends on if it hits a tower or not. My last phone whether connected through just Wi-Fi Calling or on a tower would always say T-Mobile, is this a common characteristic of this phone?

I don't know, I disabled WiFi calling. When it says service disabled are you...
1.) Connected to WiFi?
2.) Are you able to make WiFi calls?
Because if my guess is right, it says service disabled because you aren't on the WiFi, and then when it says T-Mobile WiFi Calling Service or whatever, it's because you're on the WiFi and able to make a call with your signal.

No I can still make and receive calls but when I notice I cycle the network and generally it refreshes it, it's just weird.

hi all im having a problem with my S3
When ever i try to video call any one i get an error saying it could not connect and do i want to voice call instead,both phones are video enabled & connected to wifi ive tried different wifi spots, one in my house and one in my bro in laws thats just got a S3,he can video call me fine but when i call him i get the error
could it be a network issue (vodafone) or a phone setting ? ive installed tango video calling app and that works just fine but the stock calling app just doesnt work for me ?
Maybe your signal is weak, eg no 3g.

would 3G matter when im using wifi?
If I understood you right, you aren't using any app to do video calling, so what you are trying to use is 3G video calling, which uses 3G. You can't use Wifi with that.
ok just tried not using wifi but mobile data,im getting full bars for my reception and i have a H symbol for my mobile data
still wont connect via video calling
is your correspondant also on 3G network?
BOTH of you must be connected to 3G, otherwise it won't work.
yeah both where connected to 3G,i had both phones on my desk and tried to make the call
Im wondering if its a network issue,maybe vodafone blocking it
I am not sure if this applies. but for us, to utilize 3g video calls you need to ask your operator to activate it.

Skype is supposed to work trough any net connection, (as in wifi or 3g). But video call over 3g is different from voip services like Skype.
Sent from my GT-I9100 using XDA
if the video call is made via your network service then you need 3g, if you are making a video calls with third party apps like gtalk,skype etc then you dont need to rely on 3g and can use wifi instead.
still not tried skype because to be honest i dont like the app , you need to be signed in all the time to receive msgs , in the tango app ive got installed i switched from wifi and made a video call using 3G , it worked perfect
so my 3g is working ok just not the stock samsung app ?

hi, this is not entirely correct. Tango is a service app. Just like a voip service. So it relies on internet connection only. 3g video however is a service from your gsm provider. It will only use specific 3g service of your gsm and not wifi.
I must stress SPECIFIC SERVICE here. You may have 3g data enabled but may not have 3g video (or vice versa), also it needs both phones to be capable and enabled.
To check it you may try another Sim which you tested to work with 3g video calls, or try your sim on another device to make the call.

Anyone have issues roaming? I'm in Paris and can't connect to a local network at all. Won't even register. WiFi calling seems to work, but I can't get even an emergency call to connect unless on wifi

Did you add Roaming to your account before leaving to France? I would also make sure that:
1. Network mode is GSM/WCDMA/LTE Auto
2. If you search for Network Operators from your phone, does it find anything?
3. Ensure that Data Roaming is selected
Also, power off your device completely and wait for 5 min before switching on (NOT AIRPLANE MODE). These tips have worked for me in the past, not with this phone but with other GSM phones. Please let me know any resolution, I will be going to the EU very soon and I'm hoping to know the experience from another TMo user.
Hope it helps!
While in Mexico next month can I WiFi call to the US on my g3 ?
I have the HTC One (M8) and did my update (Which added the Wi-Fi calling app). I am currently in Mexico (Been here since Saturday) and I couldn't get the Wi-Fi calling to kick in while connected to a Wi-Fi. Everytime I tried to connect by enabling the Wi-Fi the location part of the Wi-Fi calling app would kick in and I would get a message something to the effect that wi-fi calling wouldn't work in my current location (Not exact words but that is what it would tell me). So I decided to turn off the locate me feature in the Wi-Fi calling app and enter my home address (from the US) and it said confirming address took a while and it seemed like nothing happened. A little while later all my text messages and my voicemail s started to show up on my phone and the Wi-Fi calling icon showed up on my status screen.
I'm going to be honest. I was also tinkering with the network connection settings and manually selected cdma/lte in the network mode and enabled Domestic voice and data. I just wanted to get some type of service (i didn't care if it was going to go into roaming because I needed to make calls back to the states). So I'm assuming I am using the Wi-Fi calling feature because I don't have the data portion on the phone turned on and I don't have international voice or data enabled. But I will find out on my bill next month.
If I'm really on Wi-Fi calling mode then the key (i think is to trick the location servive of the Wi-Fi calling app to think you in the US by typing in an address in the US and not letting the app locate you automatically to Mexico....
I was trying to upload screen shots from my phone but the web browser let's me. I will pots the images after the 19th..

I just returned from Mexico and had turned the wifi calling on my last day their. At first worked great made a few calls back and it worked crystal clear. Then it started to ask for location I tried everything even when it did accept a location over the border in the U.S.(I was in a border town) it stopped working. My friend who has the wifi calling from T-mobile had no problem. Hopefully Sprint (lol) will get a clue.
Can anyone out there see if they get the same behavior as me?
I'm in a band 12 area, with a 4 bar LTE signal.
Wifi calling is enabled but CELLULAR PREFERRED, I'm connected to the T-Mobile ASUS router on Verizon FiOS (2.4, 5ghz, doesn't matter).
Long press 1 to get into your voicemail. What you expect to hear:
"You have no new messages in your mailbox..." is chopped off and what I hear is:
"mailbox..."
If I turn off wifi, the issue goes away. If I turn off wifi calling, the issue goes away. If I change the wifi calling setting so that it uses wifi preferred or always (so the call is an actual wifi call), the issue goes away. If I force the phone to use HSPA, the issue goes away.
So even though the call isn't a wifi call, something about wifi calling and wifi, even though the call goes through VoLTE, is causing the start of a call be be chopped off.
At this point I have disabled wifi calling on my phone.

My theory on what's happening here is this:
While you're telling the system too use VoLTE and setting cellular preferred, it's starting the call on Wi-Fi calling and handing off to VoLTE.
The reasoning it's simple...when on Wi-Fi, cellular data is deactivated. VoLTE depends on cellular data. When you start a call, it establishes it via Wi-Fi calling, and establishes the cellular data connection. Once that connection it's up, handover occurs, but this causes a few seconds of Audio loss because it has to set that back up.
You can see the delay yourself by turning off Wi-Fi, then turn off mobile data. Turn mobile data back on and you'll see the delay between enabling and being reconnected too the LTE network.
Hope this helps explain the issue. It's a handoff delay caused by having to reconnect mobile data and LTE, and you likely wouldn't notice for normal calls, but VM answers immediately.

I understand what you're saying and thanks for the explanation. And I realize that when wifi is on, data is going through wifi and would have to switch to LTE for a call. So this does make sense to some extent. But.... if wifi is on but wifi calling is not, the calls happen quickly and are not chopped off. But the same holds true - the data is going through wifi and would have to switch to LTE. Your reasoning explains it for wifi calls always and wifi calls never.

That's because with wifi calling ON, the call is initially set up through wifi calling, and has to hand over once the mobile data connection is up, LTE is negotiated, and VoLTE is negotiated. If wifi calling is OFF, the call is established via GSM, then (optionally, but not usually) handed over to VoLTE once LTE is up and VoLTE is negotiated.
I've done work in the industry with VoLTE, and my day job involves VoIP, so it's not as simple as one might think. Believe it or not, GSM to VoLTE handoff is much easier than WiFI calling to VoLTE. It still explains it, believe it or not, it's just a matter of which path. It's also harder to hand off from VoLTE to GSM when you roam out of a VoLTE area... which is the primary cause for VoLTE call drops.

Why haven't they implemented that then? That hurts them in the rootmetrics etc. scores where they'd test phone calls.
For example, band 12. You make a VoLTE call, drive to out of range of LTE and the call drops to HSPA or Edge. It nevers goes back to LTE. So when they're doing their tests, if the call switches away from LTE, then they drive to an area that is band 12, when the HSPA signal gets weak, the call gets dropped even though there's a great band 12 signal.

Back to my original point though - what I'm hearing is that this isn't unique to the V10. I'm wondering why this isn't all over the internet where people are noticing that the start of their phone call is missing when wifi calling is enabled but they've set it to cellular preferred (which is NOT the default BTW).
Just an FYI for those researching (like I was), about the Xperia 10 plus' compatibility with Tmobile's VOLTE technology: it works perfectly fine. The option gets enabled automatically, but you can turn it off in settings. Also, the APN gets configured automatically for Tmobile.
I'm on the US model (I3223)

Does your device indicate that it is dropping to 3G/H+ when making or receiving a voice call? My I3223 is doing that despite it showing that VoLTE is enabled in the regular and phone maintenance menus.
