I have tried this new feature coming with the stock Oreo ROM and received a message from my mobile carrier initially, welcoming me to WiFi calling. All network settings seemed to be working fine, I was also browsing internet with no problems, all apps were connecting and responding as expected. However the first time I tried dialing one of my contacts I've got a message "Server error. Try again later." on the dialing screen itself. It looked like the call couldn't be connected. This happened to all outgoing calls, I suppose to all incoming also although I couldn't confirm that.
I tried many things like restarting the phone, turning data on and off, going into flight mode and disabling it, in the end I reset all network settings disabling LTE advanced services before doing that and enabling them again after the reset, but I still get that error. If I disable LTE advanced, all calls get connected with no problems.
Does anyone know if this is something with a list of supported devices explicitly enabled by the mobile carrier in their network? I am considering calling my carrier for more information but the fact itself I have got a welcome message means the device has been detected as part of the advanced services network. Perhaps there are some network settings I need to enter? Anyone ever used Axon 7's WiFi calling/advanced LTE features on any network?
Does that maybe include VoLTE which the carrier may not support?
https://www.4g.co.uk/what-is-volte/
Well according to the link provided and what I know, LTE is supported by my operator, but I wonder if it needs to be specifically tailored to a phone model by them and/or the 8.0 update by itself is not providing such functionality or it is limited by default. And I think it may be the first since ZTE products are never on the list of supported phones by any operator. But I couldn't claim it for sure as otherwise ZTE would not have included it at all with the 8.0 ROM and there are so many basic or very old models like LG K8 or Microsoft Lumia 550 that are supported.
Has anyone tried using "LTE advanced" on their 8.0 yet?

LTE Advanced = Volte
If your carrier does not support Volte, keep this option off.
WiFi Calling is something separate and not related.
If your carrier does not support WiFi calling, keep this option off.
You should still get LTE service with both of these options off. I personal find WiFi calling to work poorly, so I leave it off even though my carrier supports it. (TMobile US)
Also, there is a Q and A section for these types of posts. Don't post questions in the Guides and News section please.
Thanks for the input. Both of these options are reported to be supported by my carrier on their website. Also I always had LTE before 8.0 so simply wanted to try the new "HD voice and advanced communication service" as described in the latest firmware.
About posting this thread in the news & discussion section, this only relates to Oreo which was only recently released to the public so it is a completely new feature for the Axon. Most of the other threads are too general and since there will still be many people with 6.1 and 7.0/7.1, I would have hardly got any response whatsoever in there. For now I will keep this new option off and will contact my carrier for the support of the Axon and ZTE in general.

Hi Guys,
1. I am NOT an expert as to how VoLTE works in the back end.
VoLTE is the use of LTE to carry voice calls, as opposed to falling back onto 3G / 2G to carry the voice call. Advantages include, lower connection time, wideband audio, etc.
I've recently spent some time changing the CID and firmaware on my HTC 10 to one that is region specific to enable VoLTE on my handset.
It appears the way Apple implements carrier settings means that different carrier settings can be delivered to any iPhone, but it appears Android is currently managing this differently, as OEMs are creating variants of the software to cater for each region/carrier's variations.
What this means for me is, even if I purchase an unlocked device, if it isnt from my region, I will likely have to do extensive modification to enable VoLTE.
Does anyone know if Android N manages VoLTE differently? What's el-Goog thingking here?
Hello,
I have read and found success making options for wifi calling appear in the stock menu when it was absent before, however the phone is nonetheless unable to make wifi calls after enabling. Tried placing phone in airplane and turning wifi on.... or just choosing the "wifi only" option for making calls in the network menu - Resulting message always states to connect to a wireless network to proceed with the call, even though I have an excellent connection and internet works fine.
I have done an exhaustive search for methods to successfully use T-Mobile's wifi calling feature on my phone.
My initial research revealed that the option should work so long as your phone supports wifi calling as well as your carrier.
The wifi calling option was absent (as well as VoLTE) on the stock ROM, so I had high hopes that a custom ROM which included the feature would allow me to utilize the service with T-Mobile (my current GSM carrier).
After a slew of unsuccessful attempts to make calls using wifi vs the mobile network, I finally called T-Mobile's tech support who was actually quite helpful, but essentially stated that wifi calling through T-Mobile requires the carriers own proprietary software to work... in other words, even though T-Mobile likes to promote the ease with which you can BYOD (bring your own device), it would appear that the wifi calling feature is only possible when buying a phone directly from T-Mobile unless a custom rom is built which is at least partially based upon T-Mobile's own proprietary software with regard to wifi calling.
If ANYONE has had any luck at all placing wifi calls on the T-Mobile network domestically in the U.S. using the global/MEG7 version of Redmi 5 Plus, your assistance would be immensely appreciated. I have found that, although my phone does not support multiple LTE bands used by T-Mobile, I am still able to make LTE calls quite frequently in my region using the single supported band.... however, my home is a "dead zone" so to speak and, even though I am smack dab in the middle of an excellent coverage zone, my service inside the house is poor enough that others' attempts to call are unsuccessful, leaving me unaware of the call unless a message is left.
At this point, I am getting ready to throw in the towel so any advice or success stories would be greatly appreciated - or, on the flipside, a validation that wifi calling is just not possible at this time so I don't have to drive myself crazy with a continued search for which a solution does not yet (or may never) exist.
Many thanks for your help!
Good day all,
I'm encountering an issue: a fairly new phone of mine (Umidigi F1) loses its ability to get data from Verizon Wireless when I install Treble Generic System Images (AOSP-based, typically derived from phhusson's et al work). For clarification, despite being from a small Chinese company, the phone normally fully supports VZW (4G LTE data, calls, and text). While on those GSIs, I get a signal and am able to call people with it, but there is no data from the connection.
The APN settings appear to match the ones that work normally (stock F1 and a Pixel 2), so despite not being able to edit or add a new one, I am led to believe this isn't the culprit. Next, I looked at build.prop; the model, device, and brand info changed from the default states and I believe that VZW may be strict enough not to allow the altered info on their network. Attempting to modify build.prop causes a boot loop, though.
Anybody have any thoughts on what I can do? One of the comments at the top of the build.prop file indicates that it is autogenerated by buildinfo.sh. Should I attempt to modify that instead? Or maybe something else?

many MTK soc devices on pis gsi have this issue with sim based data connection. Some even have issue with sms / text.
I did at one point have data working on one of my mtk phones, only when switched connection typs to 3G. But that was not acceptable because way too slow speeds. A solution may come. but i do not know when.
umidigi-f1-tag
I just got a umidigi f1 and am trying to get it working on Verizon. I have talk ant text(sms and mms) working through sim1. However, like you I can't get data to work.
The odd thing is that I can't seem edit the apn settings. That section is missing from my mobile networks section. I am on a stock rom, not rooted.
The sim I was using is a page plus sim. It gets service though Verizon via Tracphone.
I think my issue is that my apn is not set correctly.
Success!
Go to the phone dialer and dial
*#*#4636#*#*
Go to phone information and change your preferred network type to lte only
The default is lte/umts which probably just good for GSM phones
You should see a lte connect. Hit the ping test to verify if you can ping Google.com
Edited to say, the phone is kind of flaky with regards to the APN setting so ymmv. It was working for me for a while then stopped...
Edited 2: Okay I figured it out. To reveal the Apn menu on Verizon, change the preferred network to LTE only as above, then unselect 4g in the Mobile Network section for the Verizon Sim. Restart the phone. Next time you go to the Verizon section, there should be an Apn setting item. Create the proper Apn for Verizon because the default probably does not work. For me, I needed tracfone.vzwentp.
Here's the phone info screen
Here's the mobile network section for the Verizon Sim. Nonintuituve but had to disable 4g toggle but doesn't have any effect on speed. After a reboot, Apn section shows up
Hellom did you get it to work on Verizon? If so what are the full steps?
Make sure your Verizon sim card is in slot 1. Sadly, it seems like Verizon works best in that slot so not able to use a micro SD card.
On 2 other phones running on Red Pocket Verizon, everything just worked. No need to do anything extra.
Also disable wifi calling.
On my other phone running on tracfone/page plus, I had to do the extra steps in the previous posts above.
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?

Unfortuantely I was wrong about being to change them, but i do have most bands enabled. Im in Hamburg City so I should have very good access here.

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 my k30 ultra gets 5g on tmobile in my state.
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.
The phone is relatively new and since it's not mainstream most carriers don't support it yet. Some people say they have VoLTE enabled and it works but I personally switched to Singapore EX and it seems VoLTE isn't detected at all so I started digging and it seems this issue is present in most Chinese phones. (https://forum.xda-developers.com/t/guide-activate-volte-and-vowifi-simple-and-clear.4116051/) In this thread they used the Qualcomm tool and exploit the bug in EngineerMode on OnePlus phones which we don't have an access to and since we can't root or unlock the bootloader we can't modify build.prop or change any system files.
-----Maybe it's my carrier, maybe it's the Singapore ROM so please if VoLTE and VoWifi works for you could you post here which country you're on, which ROM version and if you changed region before or not.------
First a warning: If you aren't tech-savvy, experiencing issues or want to potentially turn your phone in a paper weight do NOT try this at the moment. We do not have the tool to restore your phone back (wiping data might work but idk). You can send your phone to Oppo for repair but you might have to wait for a month or two.
I don't know if you need to unlock your phone from the other thread to have access to this mode(I did have it all decrypted during this test) but in addition to the *#808# engineer mode and *#*#4636#*#*(Where you can check if you have VoLTE enabled) I found we have access to *#36446337#.
In *#36446337# I managed to enter "Protocol test switch" -> "MBN TEST" and switch my profile from Common-Commercial(I think it was this one) to Commercial-DT-VOLTE. The phone rebooted and everything is fine but "MBN Validate" is giving me an error when I run it and I can't test if it works because I'm currently out of the country and my temporary SIM provider doesn't support VoLTE.
It's probably nothing and the error is because of the lack of developer files on the ROM but I need people who can test if these profiles act like the flashing from the Qualcomm tool in the thread mentioned above.
So once again if you don't have VoLTE enabled and are feeling a bit courageous - give it a try.
I think the problem maybe for those that changed to Pakistan build on Android 10 and then switched to Singapore ex to get ColorOS 11 and dual SIM meant that things like VoLTE do not work on those builds.
I did it a different way as wasn't bothered about dual SIM. I was on A.46 UK , waited for EU to get ColorOS11 , then switched to EUEX on sec5 and downloaded ColorOS11 c.57 through Belgium VPN.
VoLTE is working for me. it's not present in SIM settings( WiFi calling is) however when I look at my call log there is a VoLTE HD icon next to all my calls, so is working.
Since being on ColorOS11, I have tried several different regions on SEC tool, EUEX dual SIM, Singapore EX, back to GB CPW to check still works and now back to EUEX. Build number always changes to different region in about phone when I have made any changes and check however VoLTE has always remained working for me and is showing as provisioned in engineer mode.
I am from Germany and have a phone with Vodafone FW originally. I switched region to Singapore EX, than installed the Pakistan FW and got C.5 and C.6 via OTA. I switched the region to EUEX (DUAL SIM) and didn't receive the update to C.57, so I switched back to Singapore EX and got the update to C.57 when using VPN Hongkong, which was quite funny.
VoLTE and Wi-Fi calling is working fine with Vodafone, but you can't toggle it in the hidden service menu, it's just active! You can activate or deactivate Wi-Fi calling in the regular settings, but VoLTE is just there, you can't deactivate it.
Both Wi-Fi calling and VoLTE are shown in the bar on the top. With the former Vodafone FW, VoLTE was not shown with an icon, but it was nevertheless working.
Hy here T-Mobile shown volte and Vodafone don't shows but on the status bar there is the volte symbol

I am in the same boat as you. I rebranded to Singapore to get ColorOS 11 update, to use 2 SIM and Call Recording, along with Theme Store, etc.
While on my previous phone (Xiaomi Mi9) I had VoLTE and VoWiFi and my carrier supports them and my SIM has that activated by my carrier, on Oppo Find X2 Pro it seems for them to work is needed special Modem Profile for the concrete carrier you use.
My Carrier is not listed at MBN Test Menu, I tried all the profiles available there, all Commercial ones and all Volte Branded ones and they are not giving me VoLTE and VoWiFi options available in Menu or VoLTE or VoWiFi functionality.
This method used to work on Xioami and Commercial EU Carriers profiles gave me the VoLTE and VoWiFi functionality with just Activity Shortcut access to this menu on Mi9 and simple dialer code to activate VoLTE and VoWiFi switch in Settings.
Oppo Find X2 Pro is not sold officially in my country and by all carriers here and that is why there is no Carrier Volte Profile for carriers from my country and thus it is not possible to activate VoLTE and VoWiFi with other Carrier Profile from MBN Test Menu.
Maybe if we find a way with a Dialer Code or some menu to activate the VoLTE and VoWiFi switch in Settings first this profiles from MBN Test menu will work...
I am out of ideas for now.

I'm pretty sure they force disable most of this stuff with region profiles (/etc/oppoRegion* folders)
At this point I honestly care more about GDPR protection,VoLTE and removing tencent/heytap crap than call recording and theme store which I don't use anyway.
So my plan atm is to wait for Oppo to release android 11 .57 .ozips so that I can flash back to european firmware then I'll see if changing region to EUEX Dual-SIM works and it's limitations.
This method might help people on EU roms with VoLTE, and I'll test it myself in the future, but at least for now *#36446337# lets us adjust MTU, 4G bands and some other smaller network optimizations.
Okay I don't know where to post this but I found *#649010# and this is where it gets into the spooky territory. I never tried toggling any of the options but I think "Full-port switch" option lets us connect our phone to the qualcomm diagnose tool just like the OnePlus phones from the Carrier profiles thread. I'm just documenting this code here so we know we have an alternative to the OnePlus LogKit.apk option in our Oppo phones.

Interesting to find out what these options do.
For some reason, non of these codes work for me now after doing the region change a couple of times.

We keep telling people - you gotta unlock every time you change region and even then the unlock lasts a fixed amount of time ex. 24 hours before it locks itself again

Unfortunately, the tool no longer works for me to unlock, the codes don't work. I'm stuck.

Works for me no issue. Try adding cloudflare dns to your setup, tether your phones connection to your pc while disabling your main connection and adding the number values from the original thread, fiddle with the loopback driver, disable firewall in windows or your router. Everyones connection and setup is different you just gotta find a way to make it work on yours.
Tl;dr it works you just got to tinker with it

I am in the same boat as you. I rebranded to Singapore to get ColorOS 11 update, to use 2 SIM and Call Recording, along with Theme Store, etc.

Did you have the call recording option right after you switched region? I changed to Singapore Ex right after I got the phone, didn't see that option. Then I upgraded to ColorOS11, still did not find that option.

You have to give permissions to 'Recording' app, then open enable it in 'Call Settings'

Do you mean recorder App?
Already given all permission but still no call recording option, and the recorder only has cloud sync on its setting
