I really need WiFi Calling in order to reasonably use this phone for calls from my house due to a poor Network signal. There is no Wifi Calling option in Calls -> Settings or in Settings -> Network & internet -> Mobile network anywhere. Also when I do *#*#4636#*#* and go into Phone information Wifi Calling Provisioned option is grayed out.
Nope. Last time I saw wifi calling available was on the XZP. Wasn't an option for the XZ3, and still not an option for the Xperia 1. Try giving tmobile a call or maybe sony support and ask if they can add wifi calling support.

Option is here for me. Can you not flash a non branded firmware?

Which frimeware is that ? Is that US unbranded
Nope, no wifi calling for me. I originally had the J9110 model (international dual sim, hong kong) but i recently flashed it with the US firmware. No dice, unfortunately. But since changing to the US firmware, I now get VoLTE and group message in Android Messages. It's a start.
Ya VoLTE is working fine and appears as provisioned in the hidden menu. So it seems like I will have to do something similar to what I did on the XZ Premium in order to get WiFi Calling...but I will wait until there is a DRM backup process.

I see the same thing as you. How did you do it on the xz premium?
I had to root it and flash a zip that someone made for it, it might be possible to use the same zip but I'm not going to root mine until there is a DRM backup method. I barely every talk on the phone without LTE service so it's more so just really annoying not having WiFi Calling. I think a bunch of people were using the same zip for the 2017/2018 xperia phones to get it working.
I have XZ premium and XZ1 and wifi calling option is displayed when I use the Jio sim but not displayed when using Airtel sim (using Airtel broadband), so our phones do have wifi calling facility but working only with Jio sim, although Sony is not shown in the compatible phones list. I am in India.
That also stresses me out on My Xperia 5. Don't know If You talked about My Zips for VoLTE and the other Features but i didn't get it to work actually on Android 10. Possible that i just don't have the right Firmware atm (Customized EU / My Devices Firmware isn't Out yet), so i'm using Custom UK Firmware but that should also work... I'm a bit confused so i switched to GSIs which Made it even worse... Looks like we should start making Custom Vendors for our Xperias since the Methods changed over Android 7-8-9-10
Can you flash the dual sim model to work with a single sim firmware and does Wi-fi Calling Work later?
yes, that's what i did with my xz3. volte works with tmobile, but not att.

Same here. If you just want to access the network settings you can download an app like "ForceLTE" or similar.
I'm facing the same problem, I am appreciated if anyone have the solution?
Check your carrier and location
Whether you can use VoLTE or not depends on a few things:
* Your location, your account with your carrier, and the model of your phone.
* The carrier, carrier account, location, and phone model of the person you're calling.
* Some carriers support VoLTE only in certain cities or area codes. Contact your carrier to ask about your area and account.

Thanks for your reply, the problem is I have no problem to have VOLTE by using Galaxy S10 with same sim card and I couldn't find the volte "switch" in the oppo UI and couldn't turn on/off. As a result couldn't use the VOLTE function. Therefore I do think it is the firmware problem from Oppo.
I just thinking about if I could flash the official Taiwan rom of same global phone model to my current one for solving the problem. But I'm not sure if it is workable or not.

Ah. I have CPH1919 (UK) and only option is call over Wi-fi. There is also no way to get to the hidden service menu either like in every other phone I've had.
If you know for sure that Taiwan firmware has it, then I suppose, in theory, it would work providing that it is also definitely CPH1919 - any other variant has different partition structure. Be careful. Read around and let us know. Good luck
I have a CPH1919TW, it's using the same global firmware as CPH1919EX (even Oppo TW provides CPH1919EX ROM for download), the phone will ID itself as CPH1919TW.

Hey guys,
neither my Wifi Calling, nor 5G doesnt work on my Redmi K30 Ultra. Not sure whats the deal behind it, maybe its the Mediatek chip or that it doesn't pass Safety Net or that its not made for Europe.
Anyway: Can we hack this somewhere? Maybe modify some props or something and magically make it work?
Thanks so much! <3
More info: I've done the usual stuff like activating Wifi calling, VoLTE and 5G in settings and also disabled carrier check via number code. I also tried all 3 big carriers in germany
Telefonica/O2: Nothing works
Vodafone: LTE "works", it shows an HD icon at the top but Wifi Calling doesnt work and 5G doesnt either. Shows both VoLTE and Wifi Calling as enabled in Phone Info.
Telecom: Nothing works, but it shows in Phone Info that VoLTE and Wifi Calling is enabled.
@Mirardt
Per description the phone supports Wi-Fi calling, VoLTE and LTE, so I think it's not a chipset problem. Carriers will typically sell these data services with smartphones as part of a bundle.
I guess it is a problem with carrier ( data plan chosen ). You can try to contact your carrier and check if everything is correct from there end.
In no case your issue has something to do with SafetyNet API what is an anti-abuse API application developers can implement.

Hey there, yes everything is activated from the side of my carrier and also i spoke with vodafone technical support and they activated everything they could, reset the network etc.
Also both VoLTE and Wifi Calling work on the iPhone with all of the cards. So it has to be something on the phone.

Sometimes they just block per device model (supporting only phones that were certified for their network) and you need to convince them to let you in
Or, you could (again) play with props like ro.product.manufacturer and ro.product.model to pretend you have some fancy Samsung - bcs if it shows enabled in the settings, it's likely blocked at the time of handshaking and negotiating to use the service
It's also possible to capture the UE Capabilites offer (see attachement for my LTE part) and response - I will try to find where was the URL with know-how and instructions

I talked to a vodafone technical support guy and he said that everything is fine and open from their side. Also my phone runs with your fingerprints (Mi9T) for a week or so and it didnt change anything.
Do I understand it correctly, that all the methods you linked there only work with Qualcomm chips? Cause the K30 Ultra does have a Mediatek chip. :cyclops:

If the doc is only about Qualcomm, you will need to Google for e.g. MTK bands UE Capabilities
But MTK was usually more open, people were even able to easily change IMEIs.
There used to be a code for MTK Engineering mode, with options to enable bands and so

Ok do I understand correctly that UE Capabilities are parameters that my devices has that sends information if it can do 5G or VoWifi and so on?
After a bunch of Apps that refused to work with my phone (unknown device not supported) I did found one that looks promising. The problem is that I have only littly orientation and understanding. Can you see what setting might be relevent and maybe if we can get those UE Capabilities changed inside the app?
What I tried is switching the "Entitlement Status" of Wifi Calling on "Enable" (It was disabled as I opened the app), but nothing changed. The Entitlement server is left blank, maybe that could help?
Also I just swapped every possible thing from "false" to "true" inside ePDG Config, but it didnt help so I reseted it.
If you (or anybody else) could have a look and give me some direction I would grind it out myself!
edit: Upload doesn't work on this forum somehow, strange. Here is the Gdrive link.
Ok I just looked through every single option their is, screenshoting everything that seemed relevent.
There is band information that seems like it is what you mentioned and it is editable! @zgfg
Also a couple of other direct mentions of VoLTE, like props in IMS settings.

Very interesting, (as expected) you can control many things on MTK ( too many)
For LTE bands, I think you need bands 1,3,7,20 and you don't need TDD bands.
For 5G, googling tells me that for Germany you need: n1,n3,n28,n78,n258.
Suggesting you to double-check for your operator and enable what's missing and reboot.
B20 might be available in a shopping center, or dense busy district
In the Call* and IMS-Registration* screensots, are all those params enabled or you need to open another screen for each (modes)?
On the IMS, I would put VoLTE to Default, not to CMW500 - seems to be a mode for testing equipment.
Also, you could try SMS over 3GPP or 3GPP2 (that means SMS over IMS but when you register to IMS), but check does it still work over cellular
Last screenshot says that it's not registered to IMS, but seems there are additional settings for IMS authentication (that's about registering to IMS - VoLTE is an IMS service)
I pretty much tried everything out you suggested and it didnt work. Thats why I waited to work on that until I freshly reset my phone with GApps Pico and I did that yesterday. During the Installation process there are 2 question came up:
1. There are Google Carrier Services I can install through play store. No clue what it is, does it matter?
2. I have found multiple interesting sounding apps in system/priv-apps like "engineermode", MtkCapCtrl", "MtkTelecom", "MtkTelephony Assist" and "MtkTeleService", the only one I can find in Apps is "engineermode" and i didn't manage to open it. I tried to install the other apks but it didnt allow it. Anything that might help us?

Tried everything but it made no difference. Also tried IMS test mode on with and without SMS.
Also it keeps saying its not registered in PhoneInformation1.
Should we try to change those numbers in the VOLTE settings to something like this?
Edit: I activated logs telephony logs and somehow got a bug report without even calling somebody. Uploaded it.

Wifi calling hardly ever works on foreign phones but i get 5g on tmobile in my state , the k30 gets 3 bands that havent been listed , just get a mtk engineering mode app to see what bands you can work with.
Hi folks,
The title pretty much says it all. I've got a new unlocked P6 bought from Google, using it on AT&T here in the US. It doesn't show VoLTE and when I go in to turn on VoWIFI I get an error to the effect that "we couldn't turn on VoWIFI."
The VoLTE worked out of the box on my prior phone (OP6T) but I never attempted VoWIFI with it.
Is there a special process to go through, or do I need to chat up the ATT reps? It's possible I'm not provisioned appropriately; my SIM is the same SIM I've been using on several phones over a good number of years.
Before I go in "cold" to a conversation with them I'd prefer to know exactly what to ask them for.
Thanks
Here's their whitelist:
Note this is the latest updated list (edit)
I had to have them enable it for me. I did it via chat support. It broke the ability took make regular calls but a quick call back (from a different phone) and it was fixed.

I posted (edited) the updated whitelist, with more models and harder to read
I double checked my devices... but the proof will be when they still are working.
Lol, what could go wrong?
Yeah, be afraid, be very afraid
On with chat now. Just gave them my IMEI. We shall see soon
OK, I'm all set. I think, or maybe I hope.
The chat function worked well. After getting past the chatbot I spoke with a real agent, explained my need, and she quickly took my IMEI and got it set up in the system. I got a text quickly that some ATT stuff got activated (I'll be able to turn on spam blocking and such). I was able to go in after a reboot and turn on wifi calling, leaving my preference as using Mobile Network.
I made a test call and it actually used the Wifi instead of mobile, which concerned me. I disconnected from my hotspot and tried a call, and mobile network calling worked fine, though.
Agent said my preference setting should take hold within 24 hours, in any case. We also went into the dial menu and verified VoLTE was turned on:
"Open dial and Type *#*#4636#*#* Choose Phone information option from test Screen. Now you can Enable VoLTE Support Provisioned Flag. Restart your device. Now you can see 4G LTE option under Network Bar. This will activate unlimited HD Voice Calls."
It was on and grayed out, so should be active. Just surprised there was no special icon showing in status bar like my old phone had.
Everything seems to be working so I think I'm good to go. Thanks for your help guys!
edit: after getting me set up she did a hard sell to get me to use the eIMEI for another ATT account. I declined.

See my post above. Enter the code in the dialer to access the hidden menu. It will bring up a screen that shows some settings, one will be the switch for VoLTE. For me it showed on but grayed out, which apparently is the correct setting. If it shows off, that would mean you aren't provisioned for it and need help from your carrier.

*#*#4636#*#* Thanks, very nice. On my N10+/pie this is the only place were the VoLTE setting can be seen as a toggle which is on. Yay.
Oh, one other note. Wifi calling seems to be working fine, though I haven't had a chance to check its integration with Google's visual voicemail.
What I notice is that the decision to use wifi instead of mobile is kinda hair-trigger. At my home, LTE bars are low but calls always work just fine. However, now with wifi calling turned on (with preference being mobile network), the system usually decides to use wifi anyway due to low signal. I also noticed at a grocery store, where my phone auto connects to their wifi, that when I was in the back of the store (weak LTE) it switched to wifi calling mode, then switched back to regular mode in the front of the store (strong LTE signal).
So, the system is conservative and moves over to wifi pretty often rather than treating it like a last resort. I guess that is good behavior.

I have an unlocked P6 direct from Google on AT&T. I have it greyed out but on. Does that mean I need to contact AT&T?
I had never gotten wifi calling set up on anybody my previous phones, so I definitely needed to get that turned on/provisioned for my account. The rep also told me that adding my non-ATT IMEI was needed; indeed several options became available once that was done. I don't think anybody this was needed for VoLTE though.
So pat of this might just have been due to my account history.
To cap this off, I got a wifi call just now and it transcribed fine.

Not needed for VoLTE on AT&T as I can switch the sim card between my AT&T N975U1 and unlocked N975U seamlessly. However I never use wifi, tethering or more advanced features on these two devices... so no idea about that.

I'm using latest March update Android 12.1. Rooted. Installed VoLTE Module via Magisk.
This all had happened after December update. On January 8 I got updated carrier services and SIM tray area got too hot and I had to reboot and eject my my SIM. After that my Pixel 6 couldn't receive and make calls on 4G/3G, only 2G works. Tried many things: reset network settings, reset factory settings, downgrade firmware, install custom rom, nothing helped.
So, that's my weird problem

Borrow a friend's SIM and try it in your unit. If it fails to work the issue is hardware. Otherwise it's likely a conflict between an update and the Magisk module.
I do believe however yours is a hardware issue. I don't know what caused it but the end result is a burned-out modem chip.
