No VoLTE or WifiCalling on your OP7P? Here is the Solution! - OnePlus 7 Pro Guides, News, & Discussion

I've been searching all around, called my Carrier support, opened a Bug report on OnePlus for this issue posted around the forum, no one was able to help.
I even have a thread (where i will link this one) asking people with whom it worked and didn't work... and now i found the solution. I just tested on my 7pro, and it worked!
Follow this link and the article, and report back to see if it works!
How to enable VoLTE and WifiCalling on OnePlus 7pro
I'll be happy to know if i helped some people!
EDIT : sorry, if this was discussed and a solution already found. I normally really search for answers, but i guess i missed that one. Thanks and credit goes to @dalle3 to have posted it first in this thread. I guess i hovered over that thread without seeing it as it wasn't a "solution" as per say. This is the original thread : Original thread

You have searched but obviously didn't read what i have posted here few days ago about volte switches 4 op7
Nice to see someone made article from that
cheers

Damn man, i'm sorry if i missed it. I don't like to double post.. let me try to find it.

Hi, sorry for late response, I'm still at work
No problem at all have just shared way to make it work
but i didn't start that thread , it will be better and easier to find if mod or someone who started thead change name or add solution founded .
Cheers

You can enable switches for volte, but they dont do a thing if your operator didnt certified op7...

I don't think here in Austria 3 provider and A1 are certified oneplus phones but these phones work well with ims profiles from other countries like OnePlus 6t for 3 (three at)
Have used profile from 3 uk telefonica , and for A1 network here profile from German telekom and from India booth worked volte and wifi calling ,
done with qpst
Without any problem no such need for certification
Cheers

works perfectly for Orange Romania. thankx

AT&T and there is no option to enable it in this menu

How do you turn off system log after this?

i got the Chinese version of the phone (12gb ram version for a great price from wonda). Flashed international oxygen OS and my wifi calling and 4g calling/volte work with Three UK. didnt need to do any of the above.

I'm having that very problem. The switch is there but it always reverts back to H+ when calling.

I noticed that under my running apps so I froze it and nothing happened. I assume its for sprints network, but I don't know for sure.

Ya I was thinking same thing , and wanted to freeze it, but, can you do me a favor ? If you go to the More tab in settings, then cellular networks, dose it say global ? I think this sprintDM is responsible for the default setting "Global" ( I'm on at&t ) I get better signal on global than I do the LTE setting at work . I don't wanna freeze sprintDM because if it removes Global you can't get it back without a Factory reset .
If yours says global still and u get good signal I wouldn't change it .

I changed mine to LTE a while ago. Ever since I switched it from global to LTE the global option is no longer there( this was before i froze it)I can access more options in the dialer by dialing *#*#4636#*#*
Here are the additional options I am talking about. I never had a 'global' mode in this menu, but one of them might be what you want. Also you can select the band you want.

Ya it will disappear if you change it . I tried that also while back , and it will bring back the global settings but it won't stick after reboot . A factory reset is only way I've found to get it back , there was definitely a major difference between global and LTE for me , I think sprintDM is responsible . I'm going to need mess with it when I have time to factory reset or TWRP backup ... But I think your 100 % right on what it is .
Appreciate your time

No problem, I hope you find the solution to your problem. My LTE isn't any better with either profile so for me it's not an issue. Let us know if you find a solution.

I thought it was in my head , but I tested it at work ( LTE and global ) LTE wouldn't play YouTube in my building and usually dropped to 3g , while global gave me a strong LTE signal with no drop and youtube plays fine .
Anyways thanks agn

AT&T, I have always had a horrible signal within my building at work with any phone , but this N6 and global setting its been great . Maybe the nexgen APN settings have something to do with it also , but Global is picking up something LTE isn't for me .

I may try messing with the settings to see if it gets better. All carriers are bad where I live. My LTE download speed is ~5mb/s and upload is ~1mb/s. It can peak much higher but general it's terrible. This was the vase for every phone I've used out here. What bands does global LTE use which would give you a better connection?

I found this explanation searching through reddit:
"SprintDM is the hands free activation service Sprint has been loading on their phones since the Evo4G way back when. If not longer. It has been running on all factory images on devices on Sprint's network just as long.
On Nexus6 there's carrier specific services apks for all USA carriers. Seems that was one of the deals Google struck with the cellular megacorp devils to get them to carry N6."
That seems correct from what else I read. Here is another explanation which is basically the same thing.
" SprintDM is required to trigger the Sprint hands-free activation. If this phone is to work on Sprint at a moments notice, it will need to be there."

i purchased the nex 6 from goog and upon setting it up, this is exactly how it happened. it just stuck on this screen until i called sprints cs and had them help me with the meid (i just needed to drop the last digit--i did not know this before calling)
i keep this phone in global (im on sprint) and i see sprintdm running also.
whenever i initiate the update prl and /or "update device config" the sprint dm app launches to run these.
im stock not rooted.

Didn't have any issues with mine out of the box or now that I've finally got all the T-Mobile stuff working with it's CSC and apps. I've called out and received calls in both circumstances and had zero issues. What provider are you with here?

How did you get the tmobile csc? I was having call issues too but when i changed the ims settings and enabled volte calls got better but when im in a area with bad lte service calls are taking long to go thru. Could that be a csc issue? Also i dont see a link that the op is saying you provided that fixed the problem

Extracted it from the T-mobile ROM and dropped the files into a CSC changer flashable zip for an S8, modified it so it would work on my Note 8 and flashed it.

i spent 45 mns on t mobile call then i realized why i'm calling them since my phone isn't a t mobile one lol
i flashed Kalm file
and that fixed my issue
hopefully the main dev can port it over
i don't think he's gonna be too happy with his file being modified like that

yeah it's in my thread here https://forum.xda-developers.com/showpost.php?p=73858645&postcount=17
But I redid it last night after someone confirmed that they didn't even need the Note 8 CSC files, and I deleted out everything for other carriers so the new file is only about 120mb instead of 300-something.
I can post that up after work if you want to wait, uploading is blocked here at work for some reason.
Have to add that wifi calling still doesn't seem to be working, but VoLTE does since calling does not drop me from LTE. I have no menu settings for either still, but after doing a full reset, reflashing etc I have the wifi calling quick toggle but it doesn't seem to turn on all the way - the "on" color is light-grey instead of white like everything else (dark grey when off) and in the System UI tuner app, no icon is set for Wifi Calling or VoLTE.

Yeah it's in my Exynos T-mobile CSC thread but I've got a better smaller one now. I took a pack that @TEKHD made for the S8+ F variant and switched out the files with Note 8 T-mobile files but there is a little bit left to go to make WiFi Calling work on our N950N, VoLTE works, HD voice works, video calling works, but I'm still trying to figure out what's missing for WiFi calling. It's menu isn't even showing up yet.
Current flashable zip is only 88mb and I'm fairly sure whenever I figure out the remaining files that need to be copied over it won't be much larger.

I'm about to do a factory Odin flash to stock and test the latest version - if it works properly I'll post it up with a link - though I don't want to step on anyone's toes since the core script and idea belongs to TEKHD.
Fair warning as far as right now I still haven't figured out why WiFi Calling is missing, I set up this the same way he has his S8+ pack for their F variant aside from adding a few framework files that I found referenced in the Tmo Wifi Calling apk that don't exist on a factory Korean N950N but are on the Tmo ROM, and my theory if this next attempt doesn't enable WiFi Calling is that the N950N is fundamentally either just missing more files that need to be in place for it to work and I haven't found them yet, or that it has different/incompatible versions of some files that the T-Mobile Wifi Calling needs to function.
In other words I have 2 more things to test, then I am going to try fully wiping, flashing an N950F-based ROM and apply the T-Mobile WFC pack to that, since the S8/S8+ options that enable it for those folks are for the F variants, not the N variant but the F and N have the same hardware.

Sounds good. I went through the same things with my Note 2 years ago. I figured it out and got WiFi Calling working.
Fwiw, I have no interest in Wifi Calling on my Note 8, as my signal (also T-Mobile) is always good, and I use Hangouts (or whatever) when I'm on Wifi, for free calling.
I don't have Note 8 yet, but will order soon from the same seller as you.
Do you have any other suggestions for getting everything up and running for T-Mobile (except WiFi Calling), or is simply flashing the CSC file?

If you don't care about Wifi Calling yeah I would say just root, custom kernel, and flash the CSC. You'll get VoLTE, HD voice, video calling etc

Wifi calling on unlocked Note 8

Hey guys, i created this topic as i didn't find one dedicated.
I have an issue with Wifi calling.
I bought a Note 8 from Samsung, so it is unlocked. On my notification screen i have a wifi calling button which is blue (so activated!?) but at the same time grayed out (i cannot interact with it). If i go to Phone app and Settings i do not have any Wifi calling option nor in the system apps as a service. So basically i dont have the wifi calling function and i really need it. My operator is Vodafone Romania and from what intel i gathered googling i called them and ask them to activate it (maybe push something to my phone, like a sms) but they said its got nothing to do with them. They said what i want is a setting in my phone and they only provide services.. so they cant help.
Can anyone advise me for this issue?? Many thanks
Sent from my SM-N950F using Tapatalk
I'm no expert at this but I think the solution is to flash the specific SM-950F stock ROM for your operator (you'll need to use ODIN for that) because it will have the localized CSC customization that you are looking for
Settings>Advanced Calling > Wifi calling enabled is an option on my phone
mozell_rowell your phone is unlocked? I do not have this option on my unlocked phone.
I have discovered that the unlocked XEU firmware allows Wifi calling on EE(UK) but doesn't allow VoLTE, for that I needed EE's EVR firmware.
I had set up a new contract for my phone so Wifi calling didn't work for the first few days, causing a bit of confusion.
Anyway, you may be facing similar issues.

I'm on Vodafone UK and bought direct from Samsung and now have wifi calling
There was a threads on UK Vodafone forums about this problem it was not working even for phones direct from Vodafone
The solution is to call tech support at Vodafone and ask them to send the configuration to "update the provisioning" on your handset ... this is not same as mms or web configuration .
Good luck

The setting is hard to find. Go to settings>apps>system apps>WiFi calling and enable it there. If you have Verizon, it will NOT WORK. I learned this the hard way, and had to return my unlocked phone. Supposedly, wifi calling will work with most other services.

I tried that also. Been reading everything i can find on the web about it. Tried many things, unfortunately there is only one place where i have wifi calling (in my notification bar near other buttons but...i cannot interact with the button).
My disappointment is even higher now... I've called Samsung (in my country) asking them if its possible to flash my phone with a Vodafone branded ROM (i know i can do it myself but wanted to see what Samsung has to say in this matter). And...lol...they said they do not flash roms on request...lol. I think not many people know about wifi calling in my country. It looks its up to me to solve the issue but... naturally I'm nervous about it because i dont want to lose my guaranty.
From what i learned its only a matter of flashing a CSC from a branded ROM. Unfortunately i haven't flashed anything for 4 years now.... i am scared...and not afraid to admit it I did pay for this phone a lot of money

I tried that also. Been reading everything i can find on the web about it. Tried many things, unfortunately there is only one place where i have wifi calling (in my notification bar near other buttons but...i cannot interact with the button).
My disappointment is even higher now... I've called Samsung (in my country) asking them if its possible to flash my phone with a Vodafone branded ROM (i know i can do it myself but wanted to see what Samsung has to say in this matter). And...lol...they said they do not flash roms on request...lol. I think not many people know about wifi calling in my country. It looks its up to me to solve the issue but... naturally I'm nervous about it because i dont want to lose my guaranty.
From what i learned its only a matter of flashing a CSC from a branded ROM. Unfortunately i haven't flashed anything for 4 years now.... i am scared...and not afraid to admit it I did pay for this phone a lot of money

I am in the same boat as you, I live in NYC got an unlock phone thinking i'll get by with the HOTSPOT. But it doesn't work and I have no WIFI calling and no CAlling PLUS (sprint)
and would like to flash it to the stock ROM, so I don't have to go trough the procedure of returning this phone and getting a Carrier version.
Let me know how you make out. I can't find anything on youtube about this
I got probably a solution for some. You can install shorcut master (lite) from Play Store. Go to apps explorer and search for IMS settings scroll down to last one imssettingslauncheractivity and launc it; then you have to switch all those toggles to on under ims service switch. Restart phone...and for some now all those services will work including volte and wifi calling.

I agree fully with @pigglett post above. (last Paragraph.) ......
................
" The solution is to call tech support at Vodafone and ask them to send the configuration to "update the provisioning" on your handset ... this is not same as mms or web configuration ."
....................
I noted that you already did this.(speak to service provider)
Wifi calling,
however depends firstly,
if you phone
and Rom support this (yes... your phone should ? )
Then it depends on your service provider..!
to activate wifi calling. (even though you might see
relevant wifi button etc in settings)
I am with service provider Vodacom ( @ Vodafone)
Above, is the procedure i had to follow.
I have volte , and wifi calling enabled on my device.
I also tried all sorts of shortcuts /options.
No luck
I would advise you to speak to
someone in senior management (technical section) Otherwise you wasting your time.
Good luck
I have just come off a web chat with Samsnug Uk and the Samsung representative confirmed that their engineers have now confirmed wifi calling is disabled on UK handsets until they are happy that it's working ok, I had spoken with Vodafone prior to the call today who have enabled the function numerous times on my account but to no avail The Samsung representative said they would release an update for NUgget once they were happy it was working ok. I asked for a timeline and was told that information was unavailable.....

The majority of my calls are wifi, including several over the past day or two. I would be surprised if Samsung intervened in the manner described without attracting a significant measure of publicity.
The issue is Vodafone Romania does not support WI-Fi calling. The only networks in Romania supporting such feature are Digi Mobil (https://www.rcs-rds.ro/volte-vowifi) and Orange (https://www.orange.ro/tehnologii/apel-wifi/). I have the same unlocked dual sim Note 8 (pre-ordered form Altex) and am with the same carrier (Vodafone Romania). I enquired with them about the feature and their consultant told me that such feature is not yet supported. Moreover I inserted my wife's Digi Mobil SIM into the phone and it works unexpectedly well, the option in the notification panel became accessible and was able to use Wi-Fi calling. I know this is not exactly the response you were hoping for but unfortunately, at least for now, it seems we have to live with it.
Cheers!
I don't think you'll be able to enable it until the phone can detect that your provider is actually offering wifi calling as a service

Is Volte and/or Wifi Calling working on the X50

I need the dual sim and need to make sure Volte at least is working, particularly on T Mobile USA and EE UK
Not working it has it just haven't been able to provision it

So after several emails with Realme I was finally able to talk to someone, they did call me as well.
This person gave me a song and dance lie that Volte in fact wasn't shut off and also said in his response there is no way to see a toggle switch either. Which we both know to be an absolute lie.
I told him people are complaining across forums from various countries, it clearly fell on deaf ears as the company line of it is on was repeated. Then I was told also it doesn't work on T Mobile because they're not in the North American market and didn't install T Mobile firmware. Well, you don't need to and it doesn't matter where in the world goes as long as the carrier has Volte and the device has it, it works.
It's clear they know it's shut off on purpose and just tell lies with no intention of turning it on. The only way anyone who buys one of their devices is going to get it is to root the device and go in and turn it on yourself.
Not sure how I see this company growing if this is going to be their attitude and behavior.
Thanks for the update ROOT here I come

Let us know how that works out
Have you complained to realme? I ended up sending an email to their President of India and Europe. That's how I got someone to actually give me a response then call.
I also have a Umidigi A7 Pro, it's a $100 device and yet VoLTE and Wifi Calling works no problem.... Yet Realme can't seem to get its act together.
I also have a umidigi power3 and volte and vowifi works there. So realme needs to get there act together.

I'm wondering is root is absolutely needed and if like their sister company Oneplus who hid the function switch in the 8 models, if using the QPST tool would get you to the menu to change the VoLTE profile and get it working on their devices.
From what I am seeing the two companies both are now hiding the menu's, so that tells me they're both following the same game plan. There's several posts and a video showing using QPST to change the profile and get VoLTE working.
Do you think this would work?
Hi all
Did you find a way to activate VOLTE ? I have a x50 pro 5g, settings made for 4g brands, volte OK with my provider but not on the phone.
Thank you

Question VoLTE not working since OneUI 4.0 Beta installation

Hello All,
I posted this in Samsung Community, but unfortunately none was able to help. I am hoping XDA members could help fix this issue.
I am facing a strange problem with my S21 Ultra Unlocked which was directly bought from Samsung. I had enrolled into OneUI 4.0 beta when I was in the US. I was using Sprint connection then.
I had to travel back to my home country (India) and I am using an Airtel sim card (LTE) here. Now, the strange problem is that LTE (data) works here fine. But, VoLTE is not working. The network changes to 2G for phone calls. I am assuming that the auto-switching bands which was introduced in OneUI 4.0 is causing the problem.
Using Smart Switch PC, I rolled back to One UI 3.1. VoLTE and WiFi calling started to work again. But, soon after I got update notification for One UI 4 beta. To confirm that it is indeed an issue with One UI 4, I installed it again. And as expected, I am not getting VoLTE or WiFI calling again.
Since I changed from Sprint to Airtel, I am not able to withdraw from the Beta program as well. I am getting the error "One UI beta features aren't available because your service provider has changed".
Also, I am not sure what the final One UI 4 will offer. For the first time in my life, I am seeing an Android upgrade causing my phone to not able to connect to VoLTE.
I am also attaching the screenshots of Phone Information. As you can see, in OneUI 3.1, VoLTE and WiFi calling are provisioned. But in OneUI 4, both are not available. I am assuming the issue is because IMS is not registered. But, I am not able to find how this can be fixed.
Thanks in advance for your help.
Thanks,
APS

A quick update - I updated to final version One UI 4 and the issue is still there. I am still not able to get VoLTE or WiFi calling in India.
I am having similar issue. Were you able to figure out anything?

No. I have started a new thread in Samsung US Community. Let's see if it reaches the right team who needs to fix this issue.
Since the issue was previously in the Beta version, I didn't get much support. Now, I can see more people facing the same issue since OneUI 4 final version is out.
Can you please provide Samsung members thread link here (or subject line which will help me find it).. I will reply with same issue

Yes. I've noticed this since the beta started, was hoping it would be fixed by the time stable is released, but looks like it isn't.
VoLTE/VoWiFi worked fine in Qatar with One UI 3.1 (US unlocked model) but is unable to activate on One UI 4.
It's a shame, but they probably won't fix it since it still works alright with US sims. Maybe it will be fixed in One UI 5 accidentally next year the same way it broke now, but don't hold your breath.
I would once again rollback to One UI 3.1 and wait for a stable Android 12 One UI 4.0 however it may never work with that device in your region. I won't be updating until they release a better version, still too many bugs. Your best option is sell it and buy your Service Provider's device, that's a permanent fix.

I am on stable One UI 4.0 now. Still it doesn't work.
I cannot sell a device that has such an issue now that I am in India. I will probably sell it once I am back in US if Samsung doesn't fix this issue before then.
Go to settings -->general> reset ----> reset network settings
And reboot after
Volte shou´d work again
Hey i was having this same problem, but seems to have disappeared since I installed SM-G998U rom. I didn't install Userdata and seems I didn't get any bloatware plus activation is still on. You can try.

That won't work, and is completely irrelevant to the issue at hand. This only applies to the unlocked US model (U1) - the OneUI 4 update misconfigures VoLTE for international SIMs.
U will work, but the branded firmware shouldn't be required, U1 is currently broken.

Did you lose the data? I already factory reset my phone trying to fix this issue, rolling back etc.
