Had that feature enable for many version and always worked. Problem is, you need to have a provider that support it. I'm with Rogers and here, if you don't have a Rogers phone, they don't support you. I called and did many support request and they always said we don't support you. All they have to do is to add my imei in their database but they say it's not like that.

I even prove to them it's not my phone by taking my gf Sim card (she have a Rogers pixel phone) and putting it in my phone. Volte and WiFi calling worked for 10 minutes until it locked it, I was even on a call when it happen. Then when I put my Sim in my gf phone, it took about 10 min for it to work.

Someone on a 7T Pro forum found out about this thread and I thought I would give it a try. I used the latest version of the dev.bluehouse.enablevolte app (v 1.2.3) and I was able to activate VoLTE/VoWiFi on my 7T Pro. Good find.

OP7 Pro - OOS 12.1 - GM1913_11.H.36 - Country: RO - Carrier Digi

While the VoLTE/VoWIFI settings have appeared after doing this stept it still doesn't work. Last time on OOS11 I had to copy some MBN profiles but from what I've read in this thread that is no longer possible on OOS12.1 (at least not easy)
[OnePlus 7 Pro Guides, News, & Discussion] caracciola:
you could try to reset network settings and maybe that could change your MBN profile .....

because i also updated now to the same build as yours and when i saw i lost my vowifi and volte

but i have access to engineering mode and when i saw the profile which was loaded it was Free-VoLTE

of course i changed and started to work again ...

thats why maybe you could get lucky to reset the network settings (with sim and without sim) perhaps that could work so to change the profile

good luck
[OnePlus 7 Pro Guides, News, & Discussion] tmihai20:
@neohq I am on Yoxo/Orange and only VoLTE works, VoWiFi does not. I have read on a Romanian forum that it probably works on Vodafone. Digi must be missing its profile, you are not the only one experiencing that.

FYI: I updated to F.20 (which will be the last update for OnePlus 7T Pro) and I had to disable an option in Developer Options (Permission monitoring) in order to get Shinzuku to run. I did not have to do that on F.17, the previous version.

For some random reason, yesterday I noticed VoLTE started working again on my 7T Pro running OxygenOS 12.1 (F.20). The only thing I did was to install the latest Google Play system update and reboot. I think VoLTE is working as it did before. I also updated the Pixel IMS app to version 1.2.4.

Check what permissions the app has and give it to the app. If it still does not work, it may be something related to Oppo OS.

Hi, I have several questions before trying to do this:

1) Do I still need to keep Shizuku app after everything's working?

2) Noticed the Pixel IMS developer does update the apk, do I have to reinstall the newer version each update? Or I just leave it as is?

3) Is this a permanent fix to enable VOLTE/VOWIFI?
[OnePlus 7 Pro Guides, News, & Discussion] lastbutnotleast:
This should be sticked everywhere. OP8T is finally having VoLTE and VoWiFi. Remember only that after each update, even small, you have to repeat steps: 1 command in adb console and one switch in PixelIMS. Also i tested this solution on OnePlus 7T. It works and both services are active but it doesn't change a fact that they are not used. Tested on few calls and nothing works. 8T on the other hand works flawlessly.

Vodafone Romania - OP7T Pro - VoLTE working with stock settings after update to 12.1. Even though there is a switch in Settings regarding VoWiFi, it still doesn't work. Using this workaround, upon opening pixel ims app, the VoWiFi setting is already enabled but still cannot register in the IMS in aeroplane mode. Tried a couple of times to enable/disable vowifi, restart, but nothing. Only VoLTE works :(

Hi everyone.

I updated my 7T Pro to Oxygen 12.

Prior to this VoLTE and VoWifi was working fine with my phone and carrier.

After the update I have followed the steps in the original post with Shizuku and IMS.

The VoLTE and VoWifi has now been activated in the menu, but

- The IMS is not registered

- VoLTE is not working.

- VoWifi is not working

- Data usage during phone calls is not available

Anyone have a step-by-step guide to fix this?
[OnePlus 7 Pro Guides, News, & Discussion] spinoza23:
Same here with my old OnePlus 7 pro...

Same history all switches are available but it doesn't work at all
[OnePlus 7 Pro Guides, News, & Discussion] caracciola:
Well the thing is that the IMS is not registered is probably after the update your MBN profile has been changed which is not compatible wirh your operaror...

You could try to reset the network settings and restart maybe that could bring your Volte working

If that doesnt work then the onky option is ti get access to engineering mode so you to be able to change the MBN profiles which at the moment of writting there isnt a free option to get access to engineering mode :)

[OnePlus 7 Pro Guides, News, & Discussion] Madzskie75:
@caracciola It doesn't work since the "System utilizing VoLTE" switch is disabled or greyed out in the Pixel IMS app. Although there's that functional switch like "Use Mobile Data during calls" in the Advanced Settings under Mobile Network but it doesn't do anything good. Even the status bar icons switches doesn't include VoLTE anymore. I pretty think that the developers of the latest OOS 12 build update for OnePlus 7 Pro hated to included VoLTE so much ignoring how important that sim function is especially for more advanced SIM cards that exclusively employ VoLTE for their calls and other value added serevices (e.g. DITO Telecom in the Philippines uses only VoLTE enabled handsets and cannot function otherwise).

I think the only viable solution for this VoLTE problem is to use the Magisk method but riskily requires rooted devices using this guide:

Agree with this. Enabling VoLTE using the latest Pixel IMS or not unless your "IMS Registration state" is still unregistered, all will not work.
[OnePlus 7 Pro Guides, News, & Discussion] caracciola:
@kmahesh @dryice213 and everyone else

If you managed to get the Volte/VoWifi

Switches on the settings and the Volte/VoWifi(if your operator supports it) is not still working then you are missing the MBN profiles on your phone which are compatible with your operator

Then

You need to have access to engineering mode, which at the moment there is not a free way to get access to engineering mode without a root

Go to this thread and the last couple of pages of the threas read it and maybe there you could find a way how to ger access to engineering mode

caracciola - thanks for the pointer on MBN incompatibility. I dont mind paying to get into engineering mode. Looks like (1) I need to be rooted to go beyond that (2) I should be on a windows PC.

[OnePlus 7 Pro Guides, News, & Discussion] caracciola:
You dont need to be rooted to get access to engineering mode... But you need a token (a code) to unlock the engineering mode .... Read again the thread .. the first page on the link which i posted above ... To see how it functioning the token

And dont bother with oneolus customer service ... They would not do anything about that .... If your operator doesnt support "Officialy" your phone they would not do anything.. jjst a waste of time

Use that time to read more and how to get the token and who to contact and how to contact the person so to fet the token and unlock the engineeeing mode

And then on PC you can load the MBN profiles with PDC

I want to thank the OP for the info to enable Volte and Vowifi sliders.

Unfortunately I still can't use volte and vowifi because I need a token to unlock engineer mode to further use PDC and change the profiles.

If anyone finds a way to unlock tokens for free then share with us guys. It's not ok to pay high amounts of money for a token. A user named daniha (he is now banned from xda) asked me 15$ for a token that works 24h.

This problem is only for operators who do not provide volte profiles by default for phone brands.

If I use my sim card on a Samsung, volte works perfectly, but not on my Oneplus.

I have tried these instructions and they worked to enable VoWiFi switch (I only needed to use pixel app 1.2.6, the one in the first didn’t work for me).

Unfortunately at the moment VoWiFi isn’t working for me, I need to understand if this is due to lack on configuration (MBN file side) or to the Wi-Fi network I am testing with (carrier WIND3).

Thanks

Update:

it doesn't work, even with a Wind3 Wifi network, I need to select another MBN config (h33 denmark).

I don't need to edit the file, just to select another profile, already included in original OOS.

[OnePlus 7 Pro Guides, News, & Discussion] myfreexp:
I seem to have a totally different problem. First of all, the command above did just return "sh: /sdcard/Android/data/moe.shizuku.privileged.api/start.sh: No such file or directory" on my OP 8T (EU).

Then I tapped on the Shizuku App and found this similar but different command:

adb shell sh /storage/emulated/0/Android/data/moe.shizuku.privileged.api/start.sh

This then did work in so far as there was at least a response:

C:\Users\Michael>adb shell sh /storage/emulated/0/Android/data/moe.shizuku.privileged.api/start.sh
info: start.sh begin
info: attempt to copy starter from /storage/emulated/0/Android/data/moe.shizuku.privileged.api/starter to /data/local/tmp/shizuku_starter
info: exec /data/local/tmp/shizuku_starter
info: starter begin
info: killing old process...
info: apk path is /data/app/~~9djaXvNTwNuxZP3O8J3FCw==/moe.shizuku.privileged.api-38i9QJxbjN5hIEw_2uPXmQ==/base.apk
info: starting server...
info: shizuku_starter exit with 0

Hmm, "exit with 0" doesn't sound too good. Also, unlike said in the original post, there was no "somewhat like "Shizuku is running" at my phone. Instead, there was just nothing.

Therefore I was reluctant to open IMS.zip, as the guide said "Download pixel ims from the attachments exctract and install it, but do not open it yet".

Any idea/help how to procced and what the feedback "shizuku_starter exit with 0" means…?

I should add that VoLTE worked fine until 11.x, but after I updated in a number of steps from 11.x via 12.x to 13.1 yesterday, the VoLTE switch is gone (and VoLTE does also not work).

EDIT: After once running the ADB command with "/storage/emulated/0/Android/" instead of "/sdcard/Android/", it now works also with "/sdcard/Android/" (but with the same result).
[OnePlus 7 Pro Guides, News, & Discussion] myfreexp:
Update to my previous post above and to make a long story as short as possible:

First I was confused as I misunderstood the guide in so far as I thought that I'm forced to use ADB on my laptop, because my 8T is not rooted. The disadvantage of using ADB via a cable connection to the computer is that you don't see any response on the phone that the Shizuku server is indeed running. So after I realized that (because of Android 13) it should be possible to use wireless debugging, I tried it this way and (after some other confusion on my part), I successfully managed to do the pairing with Shizuku and this finally worked:

Aha! There we have the confirmation "Service started" now. This confirmation I did miss yesterday when I tried it via ADB on the laptop.

Then I started the Pixel IMS app, but did instantly get the following result:

Hmm, that doesn't look very successful. I was already close to giving up completely, but did then read about the developer option "Disable Permission monitoring" in the Shizuku manual. As I didn't find it on my German interface, I switched to English and found it quite at the bottom of the developer options. Then I switched back to German and learned that it is called "Erlaubnisüberwachung deaktivieren" there. The translation is correct, but I was simply looking a lot higher near the "USB Debugging" option. So I enabled this option.

Only THEN I was able to give permission to the Pixel IMS app "all the time" (as said in the guide), and did see this:

That looks a lot better. BUT: It's simply not true, VoLTE is still NOT "enabled by config" (at least there is still no VoLTE switch), AND I don't see any VoLTE symbol when doing a call.

The button "CLEAR SETTING" doesn't do anything (what should it do?), and "ENABLE VOLTE" is greyed (as it says that it's enabled already). Also I can't change any of these options.

So: MIGHT it be that VoLTE is enabled by default on this phone and always activated, just without displaying it at the status bar and without the option to disable it…?! So that the whole procedure is/was just redundant and not necessary?

Comments welcome.
