I'm in Poland, I just bought the SM-G781B/DS (XEO region) last week. Sometime after updating to latest FW the device stopped connecting to cellular. No outgoing, no incoming, no mobile data. It shows getting reception but doesn't show the carrier, just emergency service. I saw a thread about flashing XAA firmware with Odin but I don't know if it would work with the local bands.
I tried all the usual Vulcan nerve pinches (APN settings, SIM switching, using SIM2, jogging back and forth between 2G, 2G/3G, 2G/3G/LTE and so on. Anything I can try other than that?
I can attach some screenshots if it helps.

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:

Hi.
For those who don't know, Freedom Mobile (formerly Wind) is a T-Mobile equivalent network here in Canada, but until recently they launch a new LTE network and their site says I can use my N900A. I used their phone compatibility checker to confirm (see attachment)
However, I bought their sim to test, I get LTE data and works fast, but I can't make phone calls. It just sits there doing nothing and finally hangs. I checked the simcard on another phone and it works, so it's not the sim.
I'm using the lollipop OC1 firmware stock only. What could be the issue here? I appreciate any input.
EDIT:
My phone is unlocked (RegionLockAway) a while ago.
My *#2263# is set to Automatic.
Do calls work on the Bell, Telus, or Rogers network?
USA -> Malaysia -> South Africa - it worked a little in Malaysia, no service in SA
Hi everyone, I have a bit of a weird situation and I'm hoping someone with experience can point me in the right direction.
I bought a Note 8 (second hand) in Malaysia. It's a US snapdragon version:
When the phone boots it shows the XFINITY logo.
SM-N950U, Baseband Version: N950USQS5CRG9
Service provider SW ver. :
SAOMC_SM-N950_OYN_CCT_OO_0024

Android Security Patch Level:
August 1, 2018
The phone worked in Kuala Lumpur, Malaysia, but not very well. I was using a Malaysian uMobile simcard. There were a few places where I could make calls.. but in most areas only the LTE worked.
I usually couldn't make or receive calls or get SMS or even use MMI codes (like *123# to check balance). I could browse the internet though.
I then traveled to Malacca (a smaller city in Malaysia) and I couldn't get the phone to work at all anywhere - not even LTE.
I'm now back home in South Africa and again, the phone doesn't work here at all. I've tried sims from all the providers here. Is there a firmware I can flash that would help? I've been reading this thread, and it's a little confusing to know which versions to flash and in what order. Before I attempt something, I just wanted to run this by you guys and make sure it's not in vain, and that this phone can be made to work in South Africa?
Only the cellular functions of the phone are not working. Wifi works fine. I also noticed some people mention that they have an airplaine mode icon, I do not. I have have a circle with a line through it, and a message "No Network Connection"
All I want is to be able to make phone calls and use internet - I don't need wifi-calling or anything carrier specific. The South African networks are Vodacom, CellC and MTN - I've previously bought phones from the USA that work here before.
I don't think my phone is carrier locked because it did work a little in Malaysia depending on where I was.
When I use a sim from a carrier here called MTN:
I fiddle with the Network Mode, switching between LTE/3G/2G and 3G/2G in Settings->Connections->Mobile Networks - I get a few bars of connection, but when I try to do anything it says "Not Registered on Network"
When I use a sim from a carrier here called Vodacom:
If I go to network operators and search networks - it shows all the south african networks - I select Vodacom (for this sim) - I get zero bars in the connection strength. In the notification pull down, it says "No Service - Selected network (Vodacom-SA) not available.
Thanks!
Update
I've attempted to flash an N950U1 firmware ( N950U1UEU5CRJ2 ) .. but still no cellular connectivity.
So far I've:
1. Did a factory reset.
2. Used Odin 3B(PatcheD) with the latest N950U1 XAA firmware from updato and used BL, AP, CP and CSC_OYM, and NOT HOME_CSC)
3. Odin Passed, and the phone rebooted and erased itself again.
4. When it booted it said "Your device will restart to configure features supported by the new sim card"
5. It rebooted, with a screen with a blue image of a sim card and 3 dots.. which stayed that way for a while, then again rebooted.
6. After rebooting again, I'm now in and everything works except the cellular stuff .. still No Service. The signal icon on top shows the empty triangle (no bars).
I updated my Samsung S20 FE 5G to latest firmware Android 11 via OTA. After update, the network data stopped working on sim1 tray. I can receive calls, send/receive text messages, but no network data. I reset network settings, made factory reset, it did not help. Strangely, when I insert same simcard into sim2 tray, the network data works fine. I did not have this issue before update.
Is anyone experiencing same issue and how to fix it?
This happened to mine but not always. Traced the problem today : LTE band 3 and 1 work fine, LTE band 20 no data (on Three UK). Pushing my phone to 3G/2G (network mode) and then switching it back to the original setting, in my case LTE/3G/2G fixed it (at least in the last hour or so anyway).

I am with Three UK too. After switching networks from 2G to 3G, then to LTE etc fixed my mobile data issue. However as soon as I travel to area where 5G works, the network data stops. It seems this update affects 5G modem and generally mobile data
It's since reoccurred on mine after restarting phone. Not a good sign for this update/S20 FE
Yep same issue also three UK hopefully there's a fix soon this update also broke my duelshock 4 contoller ability to work with phone,rubbish update
only issue ive had since the update was the one day of ridiculous battery drain, other than that, smooth sailing
S21 Ultra SM-G9980 256GB 5G Dual Sim
Active CSC: TGY ; Original CSC: BRI
Network: Vodafone NZ
Issue: Mobile Data and VoLTE won't automatically connect
Started happening probably after last firmware update (unsure). I noticed that after leaving WiFi network, normally Mobile Data kicks in and phone would automatically connect but hasn't been happening for the past couple of weeks. Also, whenever the phone is connected to 4G, VoLTE won't turn on.
To fix both issue, network has to be restarted by turning Airplane mode on/off OR restarting the device.
This is such a pain to do everytime and I hope someone can direct me to the right way.
Troubleshooting done:
Network settings reset
Factory reset
Replaced sim card with a brand new one
Called provider and they did network reset
Provider reprovisioned VoLTE on account
Inserted another sim from different provider. VoLTE and Mobile Data turns on automatically - no issues.
I have also cross-checked the network bands with mobile phone and Network Provider. No issues.
Called Samsung and basically been told that they can't help me.
Photos attached showing 4G connection with VoLTE toggle on but not active.
Any help would be appreciated.

Call to service provider and see if they can help. I have same model and VoLTE is working fine.
