Sprint wifi calling issue on LG G4 - spoofing your GPS location no longer working

Hello,
I travel a lot for work from the US to China. In the past, I've utilized wi-fi calling on my LG G4 on Sprint for texts / voice capabilities. Sprint doesn't allow wifi calling in China, but there was an easy work around: I would VPN to a US based location (needed to access anything google), connect to wifi, turn on global roaming and then use a fake GPS locator app set to somewhere in the US. When used in tandem, I was able to to connect to wifi calling just as if I was in the states. I've done this successfully for the past six trips to china over the past year, end of April being the latest.
On my current trip to China, I've been unable to connect using this method. The Wifi calling times out and gives an notification error in the status bar "wifi calling is not allowed in this country". Does anyone know what may have changed in the past two months? I believe Sprint does its locating via Google (one of the main reasons wifi calling doesn't work here) but that shouldn't be an issue if I have VPN access and can utilize the suite of my other Gapps.
Does anyone have any other ideas or settings I can tinker with to try to get this to work? One time I was able to pull up a screen that I've never seen before titled "self service" and it mentioned something about setting 911 location, but I've never had to mess with that in the past. Was there a recent ROM update that I may have downloaded over the past couple of months that would have prevented me from doing what I used to do (I don't remember, but maybe)?
Any help would be much appreciated. I even called Sprint to try to get my texts turned on and they just turn on global roaming and I'll be all set...I did this and that hasn't worked either. When I go to HK, I receive texts and can use data without issue, and can connect to wifi calling (confirmed last weekend).
Thanks!

Try also calling sprint they can do a uicc unlock which would allow u to use it in china gsm if im not mistaken
I cant give no help on the wifi calling as im a gsm unlock user my wifi calling has never worked. Always get a invalid sim

EE UK Wifi Calling

Hi folks, I'm having a bit of difficulty or confusion with wifi calling. I'm on EE but my phone is an XEU. There was a wifi calling option that didn't seem to do anything; no icon when enabled and no obvious network connection.
So I switched to the EVR firmware, wiped the phone and set up from scratch. Still got the same wifi calling option, still no icon or network activity with it enabled.
I don't seem to have VoLTE either, I would have thought the EVR CSC would enable that too?
Does anyone have any insight on this?
Thanks.

I have been having weird issues too with a dual SIM version and EE Wi-Fi calling. Inserting a microSD card in second slot can sometimes disable Wi-Fi calling in that I don't even see the option for switching on.
Hopefully future firmware fixes these glitches as I'm really loving this phone after using iPhones for a few years .

Wifi calling and VoLTE enabled itself after a serendipitous restart today.
Did your wifi calling ever actually work without an EVR CSC or firmware @ajdjackson ?
Edit: Looks like EE had some stuff to set up on my account, problem was at their end. My account says they're setting up roaming and could take up to 24hrs so something has happened to instigate these changes.
Anyway, now I'm really wondering if I need to EVR firmware at all. Samsung's multi CSC system should allow EE's wifi calling but EE would insist that it doesn't. Can anyone chime in?

Yes - strangely mine seems to working OK now even with the sd card in second sim slot. I haven't flashed any firmware at all.

Right, after a switch back to XEU I can confirm that EE Wifi Calling does work on a non EE phone but VoLTE does not!
So I switched back to EVR and everything's working fine again.
Quite surprising since EE have always insisted that Wifi Calling is exclusive to phones supplied by them, yet I've never read the same about VoLTE.

Hiya,
Just thought I'd share my experiences...
Like you, I'm also on EE and again like you my NOTE 8 is an XEU SIM free model, in my case from CPW. I found the same issue in that the wifi calling option could toggle on and off but the setting didn't seem to do anything; no icon when enabled and no obvious network connection.
I phoned EE on 150 for support but all they could suggest was to reboot my router at home even though I told them I also have a "work's" mobile phone (iPhone 5c) also on EE and that combination does have working wifi calling.
I decided to try a test to determine if the issue was with my Note 8 handset or with my new EE 4G SIM by swapping SIM's between the two phones. The work SIM worked immediately by activating wifi calling in my Note 8. My personal SIM was active in my works iPhone for approx. 2-3 minutes with no signal before a pop-up message appeared asking if I wanted to activate wifi calling. I obviously selected 'Yes' and when I swapped the SIM's back to their original handsets my Note 8 now magically works with wifi calling with the original SIM.
It's almost as if the menu item in the Note 8 for toggling wifi calling on and off doesn't activate the sim card even though the graphic animates to show the function activated.
Anyways, I now have a Note 8 with working wifi calling.
Hope that helps anyone else with similar issues involving EE wifi calling.
*EDIT* Hehe looks like my signature is a little out of date.

Thanks Steve. Do you have VoLTE? I can't get that working without swapping the firmware for the EVR specific one.

Hmm I don't know. I know that I have 'Mobile Networks' setting 'Network mode' set to 'LTE/3G/2G (auto connect)' as opposed to the other settings of '3G/2G (auto connect)', '3G only' or '2G only' but how can you tell if a voice call is routed over 4G? Does a special icon appear as in the case of wifi calling? Hard for me to say as I have zero signal at home and very poor signal at work so in both cases my Note 8 defaults to wifi calling.
Have you tried calling EE to check if VoLTE is only supported on branded firmware as opposed to generic XEU? I know that in the case of wifi calling their website is very explicit in stating that wifi calling is not only supported on EE branded/sourced handsets but also works on certain generic handsets such as S8 / S8+ & Note 8. Their website on VoLTE or as EE term the service '4G calling' is not so clear...

This EE Community Forum post seems to lay the blame at Samsung's door as opposed to EE's...
https://community.ee.co.uk/t5/4G-and-mobile-data/VoLTE-on-Samsung-Galaxy-S8/td-p/559521
Reading the thread fully, it seems VoLTE is only available on EVR and not XEU.

Yes, this shows the VoLTE icon which appears whenever I have no wifi or I disable wifi calling.

The discussion on EE you linked is interesting, so they do limit VoLTE to their own supplied phones. I'd recommend switching to an EVR firmware, despite the guy who says there's no advantage for the user, I've found VoLTE very useful, especially in conjunction with Wifi calling. VoLTE/Wifi calls are so much clearer, they can seamlessly switch if you lose the wifi signal and they seem to connect a bit quicker too.

Ahh there is a symbol, thanks for sharing the picture. I can confirm that do not get VoLTE and whilst it would be good to have every function that I pay for working the fact that I get zero 4G signal at home and at work where I spend 90% of my time means I'm not realistically going to miss VoLTE as my phone now has a working 'wifi calling' service. I suppose that if EE ever get round to providing coverage in the blackspot that surrounds my home location then I might consider swapping to EVR firmware. I won't hold my breath though because in the 20 years that I have lived at my current address, EE and Orange before them haven't bothered with trying to provide adequate cellular coverage.
I remember going through exactly the same crap with my Samsung Galaxy S2, Orange firmware got an app called signal boost and the vanilla xeu firmware didn't and we had to do a number of things to get the app ported over to XEU. Seems like no matter how much technology advances over the years some issues never change.:silly:

WiFi Calling (EE UK) -> Phone Purchased Indirectly.

Hello Friends,
Having Googled Up & Down accross the Interwebs, I am frankly Stumped.
The UK Mobile Network EE offers the P8 Lite (2017 Model) (PRA-LX1) with Wifi calling directly.
Until recently they had web posts saying this phone is WiFi Calling compatible whether purchased from EE or indirectly.
However this is not the case. My Version was purchased unlocked, from Carphone Warehouse UK.
I have force updated the firmware to PRA-LX1C432B191.
I cannot get the Wifi Calling option to Display (Or VOLTE)
However B191 firmware is supposed to support VOLTE & WiFi Calling.
Suspect either some custom apps or configurations exist on the EE provided phone that is not on My handset.
I am Happy to root, Mod, Unlock and try to enable this option.
Where do I start looking? Could you tell me where I can find the right firmware,
or mods, hacks or changes to enable this feature?
Why would the EE shipped phone have wifi calling but the unbranded unlocked version not?
It is the very highly strange situation.
Cheers friends, looking forward to your insights and suggestions.

WiFi calling may need to be enabled on your account by EE tech support, this used to be the case a few years back when I was a tech support agent for them.

Confirmed, wificalling is enabled on my account,
They also did a network refresh on my account.
Still cant see the option.

*bump* anyone can help me enable wifi calling feature on this device?
the rom should support it

I'm in a similar situation, although I am still stock at LX1C432B115. Can I ask how you force updated to 191?
I had a look at an EE handset and that had the build PRA-LX1C440B163 and the wifi calling menu items were visible. I had wondered whether flashing that (or the latest ee build C44?) onto the phone was possible\the easiest way to get it working.

[SM-N950F]: WiFi calling on oreo not working?

Have an unlocked SM-N950F BTU with a Vodafone UK SIM.
WiFi calling was working fine with 7.1.1, but after the Oreo upgrade no more.
I lost the setting after the upgrade and had to call vodafone to provision the option to my phone. I have the option under settings and it is enabled, but no WiFi calling.
Called vodafone and they say that they can't see the service being registered on their side. Tried disabled/re enable WiFi calling option on the vodafone app and no luck. Reset network settings and no luck. Shortcut Master Lite no longer works.
Any ideas? Am I the only one on this boat?

No you are most certainly are not the only one! I have been struggling with this myself. Many calls, messages and a visit to a Vodafone shop and I have got nowhere with them. Considering going to EE. I have tried:
Flashing to Vodafone CSC
Replacement SIM from Vodafone
Toggling Wifi setting in my vodafone website.
Asking Vodafone to send config messages
Texting 97888
Downgrading to Android 7.1.1 and fiddling with settings in shortcut master
None of this had made any difference. Note that wifi calling works instantly if I insert a 3 SIM.
Extremely frustrating.

Just a quick note to say that I finally got hold of someone at vodafone that understood the problem and was able to send me settings to enable wifi calling.

Thanks for sharing. Any chance you know what they did? Will give them a call this afternoon again. They said they would contact me in 24/48 hours and this was Monday. - nothing new here right?

Do you who you spoke to at vodafone who sorted the WiFi calling problem? Thanks

Still have an open case with them.

Restore wi-fi calling - carrier unlocked

Hi. I'm new (and old) so apologies in advance for any faux pas. I couldn't find another thread with a problem like this, so I'm posting a new question.
Here's what happened:
I have been using Ting MVNO SIMs on two Galaxy S8 phones for about 18 months. Preparing for an overseas trip, I asked T-Mo to unlock the phones so I could use foreign SIMs.
T-Mo unlocked the phones, but now I can't get wi-fi calling to work on the Ting SIM. Tried a MintMobile and FreedomPop and the same thing, no option in the tools or phone app to activate wi-fi calling although it is activated at the MVNO and the E911 addresses are correct.
T-Mo says it's impossible that unlocking did that. Well, it happened. Ting doesn't have a clue about how/why it happened or how to fix. Samsung says it's the carrier's problem not theirs.
I factory re-set hoping it would restore the lock, but that didn't do anything. I don't get a signal at my home, so wi-fi calling is necessary. My next step is to buy new phones.
Ideas? Thanks!
