update to 8.1 breaks calling the voicemail number (1233) on tele2/tmobile network - Nokia 8 Questions & Answers

So after the official oreo update , my wife's nokia 8 cannot call the voicemail number any more. Last week it worked. Sim in another phone, it works. Dialing on the updated nokia 8, 'this number is not available'.
Can't find anything on the internet, so checking here if somebody knows what could be the issue here.
Any services that handles this 1233 calling differently then any other number?
Any hint or 'look at this option' will be appreciated as i'm pretty stuck and even tele2 customer service has no clue ofcourse.

I'm on Tele2 nl and have the same issue. I don't know what the solution is. Let's hope for a fast fix.
Edit: a temporary ghettofix is to disable advanced lte mode (geoptimaliseerde 4G LTE modus) in mobile network in the settings menu.

yeah just figured that one too. Fiddled first with 4g/3g/2g settings which made it work too. Turning off VoLTE indeed made it also work on the 4G preferred network mode

It seems that Tele2 switched to full LTE since last week, whereas before it only used VoLTE in some cases.
It could be that they forgot to register their number. I assume that the other phone you used to test does not use VoLTE?

No, but I tested in situations that didn't give me volte before, but now they do.

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.
Jake
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:

Pair 10 pro with AT&T Number Sync successful

So sorry if this was common knowledge but I haven't seen anything on this yet so I thought I'd share. I decided to try setting up AT&T's number sync between my new mate 10 pro and my LG Sport and it worked. What makes that amazing is this is the first non att branded phone I have ever been able to set up directly between the phone and a att smartwatch that didn't require me using a att branded smartphone in the middle. You can't find the ability to do it through the my att app or website but if you initiate through the watch, it will open the browser on your phone and then give you a number sync code, once you log in through the browser, you put in the code and then accept terms and it will successfully link. This phone also seems to work well with the LG Sport. Battery life is waaay better then when it's paired to my Att Note 8.
FYI, Att number sync allows multiple devices to receive a phone call or text message from the main line they are tied to. That way every thing is seen from one number. One of the requirements is that the phone must be Att branded.
So that tells me between this and VoLTE working on att with this phone, this phone was all but ready for att network and only thing missing was the att branding on the phone before att backed out.
Sorry if long l, just wanted to share to maybe help other att users.
Have you been able to get/verify that VoLTE is working on your mate 10 Pro? If yes, how did you verify it works? I have a Dual Sim 10 Pro rebranded to the US 10 Pro (did at Best Buy) with the Enhanced Voice and VoLTE options enabled. Thanks.

I didn't use the default apn that sets up when I had my att sim inserted. I used the settings from att's support page: https://www.att.com/esupport/article.html#!/wireless/KM1218306
If I remember, there were a few subtle differences. Honestly, I didn't notice if VoLTE was working before the new apn settings but I see that it works for sure with the new apn settings. My status doesn't change from LTE whether on call and/or browsing.

No problem. I was thinking, you said you rebranded to us but I wonder if by a slim chance there is some hardware difference that is dectected? Like maybe a certain band att uses. I haven't looked at the differenceces in bands between models.

Cellular bands are the same as US version; when not in a call I connect to LTE+. I can achieve cellular download speeds of 98 Mbps. Main difference between US version and mine is my phone is dual SIM Mate 10 Pro. The second SIM connects to 4G when I make a call. If I use only 1 SIM, connection drops to HSPA+. I see an option to enable VoLTE on the second SIM, but it's disabled. Have you to find a way to enable it. I appreciate your feedback, thanks again.

Does wifi calling work?
An update on this matter...
As far as I can tell Huawei has been fixing one of their shortcomings and allowing VoLTE support on many more carriers despite the phone being the wrong reason.
I've heard from a reliable source that, although I didn't think it was true, indeed VoLTE works on T-Mobile US.
Note that this may or may not depend on the version/branding of the P20 Pro.
Wifi calling does not and has never worked on T-Mobile US with Huawei phones unfortunately.

Can you try this please?
1. Turn WiFi off.
2. Make sure 4G symbol is showing on your cellular bars at the top of the screen.
3. Make a phone call. You can even call 611 for T-MO customer service, and make sure that 4G symbol still remains while on the call and that it does not change to 3G or anything else? And if you can post a screenshot, it would be much appreciated.
Are you using the CLT-L29 and what region? European or Latin American version?

Correct it's the dual sim CLT-L29 Build Number is clt l29 8.1.0.106(c636)
That method of testing would be a step backward. I have already confirmed I am calling over Band 12. VOLTE is working, atleast for me on T-Mobile. I wasn't expecting it to from reviews but it was a nice surprise.

A workaround to get WiFi calling is to download T-Mobile Digits from play store and you can use the app to make wifi calls. You may need to sign up for T-MOBILE Digits. I'm not sure. I was a beta tester for Digits and they since let me keep the service for free on 3 devices.

I've been using google voice / hangouts dialer (or whatever they want to call it this month) for a few years now. I hardly ever use T-mobile for calls, works out well when you want an international phone. Less reliance on the network features.
Out of curiosity do you remember if T-Mobile digits worked for incoming calls as well?

VoLTE definitely works and Wificalling menu is hidden. Don't think it works, yet but that might change at some point. Use a program like quickshortcutmaker and search for calling. The last option seems to be for att and the second from bottom is TMobile.

Anyone got LOS 16.0 + Three UK + native WiFi calling working?

Hi all,
I'm currently running LineageOS 16.0 on my OnePlus 3T on the Three UK network and was wondering if anyone out there has managed to get native WiFi calling working in a setup like this?
I get zero mobile reception at my work so for over a year now have been using the Three inTouch WiFi calling app which has been pretty good, however last week I received a message saying that due to upcoming network upgrades Three will be retiring the app in a month or two so I now would like to be able to use Android's native WiFi calling if this is at all possible.
Three's website says that WiFi calling is only supported on Android on handsets purchased from them on contract, however I'm a SIM-only customer. I've got the latest OxygenOS modem firmware etc. installed as far as I'm aware, so was wondering if any of you clever people here on XDA have managed to find any unofficial ways of getting the native WiFi calling working for any old network?

Wifi calling is working out of the box for me. VoLTE too*. (LOS+3+SIM only+OP3/T) Been working with that setup since the beginning of LOS16.
*With 3 you'll only connect to VoLTE when 3G is unavailable as they prioritise in that order. For some reason they don't like people to use 'Super Voice', even though they advertise it as a feature. There's a big thread on the Digital Spy forum covering 3 and 4G in the UK that you might find useful.
Edit: Try the field test number. Enter *#*#4636#*#* in the Dialer. Is Wifi Calling 'Provisioned'. See my own screenshot:
On my stock op3t there is no WiFi calling toggle to switch on. That probably explains why I don't have it despite being able to switch it on under enhanced communications under sim settings.
Is there a way to activate it? The volte calling I got by doing a code thing.

Yes the "Wi-Fi Calling provisioned" toggle is on.
I've just upgraded to the latest LOS 16.0 nightly (2019-05-02) but still no sign of the native Wi-Fi calling working.
You said you've had it working since the start of LOS 16.0. I upgraded to 16.0 over-the-top directly from 15.1, do you think that could have anything to do with it?
Are there any settings in the SIM itself which could be needed to enable Wi-Fi calling? I think my SIM is a good 3 years old or so, would swapping it for a newer one be any use do you think?

OcUK. User name looks familiar.
We're having this conversation in multiple threads.
VoWifi does NOT work, despite any previous assertions to the contrary. As i mentioned, it was flawed testing methodology.
VoLTE does work, but with Three network restrictions. i.e only when there is no normal 4G (1800Mhz) or 3G available. VoLTE is only carried on the 800Mhz band, which is prioritised lowest.
There are two very long Three 4G threads on the Digital Spy forums. Worth reading if you want the long version of what i have stated above.
Edit: Just a suggestion. Try this app so that you can monitor what Bands you are connecting to at any given time:
https://play.google.com/store/apps/details?id=com.wilysis.cellinfolite&hl=en
What you need for VoLTE to work is Band 20. (800Mhz)

The app is telling me I have band 20 so volte should be achievable but doesn't seem to be working on lineage (worked fine on OOS 9.0.6)

To save time can you post a screenshot with the App displaying that information?
'Connected to Band 20' is what we're looking for, rather than 'is available'.

I'm guessing this is the screen you want.
I also installed VOenabler v1.7 which seems to have restored volte. I haven't seen the volte icon but I'm still at home.
Edit: I installed the module before installing the bandwidth app.
Double post..

It looks like you have Wifi turned on in those screenshots. If you turn it off you should be able to make a VoLTE call. At least it looks like you should.
So has 3G always been bad where you are? I assume you don't have 3G or normal 4G reception at all? (Bands 1 & 3)
I almost always connect to one of those two in my area, although where i am now it looks like some neighbouring towers do carry Band 20. I just need to destroy the other towers to connect to it!

It's abysmal. I'm in a Victorian basement. The only reason I went with three was the WiFi calling app.
Have left the house now for some air and now I band 1 so I'm guessing I'm connected to a different tower.

So what you're seeing is evidence of Three de-prioritising Band 20. As 800Mhz has better building penetration it's all you're getting while inside. When you step outside you begin to pick up the other Bands which you are immediately switched to, whether you lke it or not.
I only latch on to Band 20 once in a Blue Moon. The coverage of the other Bands is almost total so i don't stand a chance!
VoWifi is another matter altogether. If it could work with the 'intouch' app there must be something in the app that could be added to our ROMs natively. That's my logic anyway. (Also support is added to phones bought from Three using their official ROMs, so the same logic applies).

I thought newer phones had WiFi calling by default and didn't need to rely on the carrier.
That's a very good shout but way beyond my skills. Maybe it can be suggested?

This is the official word from Three:
http://www.three.co.uk/Discover/Three_inTouch
They say 'update' which suggests that people who bought phones on contract might have received an OTA which enabled VoWifi. How much would we love to get a copy of that OTA zip!

Poor us who bought our phones right out. I wonder if this is the case for newer phones too.
There must be someway to get that zip!

ok i just quickly checked several utube videos and i see “global” device have VoLtE icon.
So I guess with global rom it will be fix bro
I have the Chinese variant of the Mi 11 Ultra and by default, I was unable to see the options to enable VoLTE and VoWifi.
If you enter the following codes into the dialer, it should work:
VoLTE *#*#86583#*#*
VoWiFi/WLAN *#*#869434#*#*
These codes disable/enable carrier compatibility check. Then go into Sim Card and enable VoLTE or VoWifi.
Since VoLTE is required for RCS in Google Messages to work, enabling this also allowed for 'Chat Features' to be ready on my phone.
Quick note: I am in Canada on the Virgin Mobile Canada network.
I did this but the icons never came up.
I'm in australia using telstra and got the china version

Did you get the pop-up stating "carrier check disabled"?
Go to settings>sim card & mobile networks>select sim 1>you should see the options here.
Hope it works!

Yeah I got it and enabled it but I can't see the volte or HD icon?
Have you rebooted?
Have you made a call to see if you stay on 4G?
I'm using EU ROM now but has VoLTE on my Chinese stock, see attached image

Even I face same problem I'm using boost sim ,I've enquares the Carrier but they said they support vote , I'm not able to get volte working in my device
Same issue. Got the Chinese variant of the Mi 11 Ultra, running 12.5.12 EU ROM and I'm on Boost (Australia). I've done all the dialler codes and still no VoLTE icon. Calls drop to 3G.
i've done a deep search regarding VOLTE on Telstra in Australia as I am facing this issue too, and I found out the following result:
This issue happened because Telstra did not share its network settings with a few companies, Xiaomi, Oneplus, and others.
On a different thread on Oneplus section, there is a way to fix it that requires root, so we add Telstra settings manually, but whenever a tiny update shows up, then we'll need to repeat it. a restart won't affect it, just an update because it replaces modified network settings file with original one.
so to summarise it, unless a software update with the new settings come up, then it won't work.
And btw, the VOLTE is working on MIUI first version of 12, and MIUI 11. but after the update, settings lost. and this is not an issue with MI 11 ultra, it is with all xiaomi and oneplus devices and a few others.
Do not waste your time on it, and just cope with what we got and be patient.

Thanks for this information, sincerely appreciated. My only concern is Telstra turning off their 3G network by June 2024. Let's hope the issue is solved before then. Fortunately my call quality is completely fine without VoLTE at the moment as reception is good. I'm sure other providers will start turning off 3G too. A very odd issue and I'm really surprised it hasn't been fixed.
Did any one manage to find a solution ?
Any solution yet to make volte and vowifi work on Telstra and boost Australia? Thanks
