Unable to use USSD codes - OnePlus 7 Questions & Answers

Hello,
I recently wanted to activate VoLTE/VoWIFI on my OP7.
This made me reinstall the oneplus logkit.
before AND after doing this I realized I was totally unable to use any USSD codes on my phone.
For instance typing *#800# or 801 or whatever gives me something like "Connexion issue or IHM code not valid" ( translated from french).
I'm not sure if this issue can be related to https://forum.xda-developers.com/oneplus-7/help/sim-card-connection-acting-10-3-update-t4030031
I don't see how, but maybe you guys see something I don't.
Thanks for your attention
Edit: I'm using the Google dialer. And I am in 2G/3G/4G automatic. I also tried 2G only and 3G only.

Try to use stock dialer and make sure you did not deleted any system app for testing.

Hidden menus and dialer codes, please post them here

I presume *#*#4686#*#* still works, but I would like to know if there are others.
For Samsung devices, you can see the voice codec used during a call by using *#0011, but I found no such capability with the Nexus line.
Specifically, I would like to know the Pixel is using AMR:WB (AT&T HD Voice) or EVS:WB (T-Mobile Enhanced Voice Service).
Thanks.
...there is a hidden developer menu which you can access buy hitting the build number endlessly...

Thanks, though that dev menu thing has been around since almost the beginning of time [Android] and it does not provide for what is in scope. For most of us who root, the dev menu is one of the first things we do.
No worries. But as you posted a thread asking for hidden menus, it seemed only polite to supply an answer...
Hadn't bothered looking at your forum hierarchy status until just now...

*#*#3282#*#* gets you data services, you can turn on/off LTE bands and other junk. you need MSL code to do anything if you're on a CDMA network.
also i tried your *#*#4686#*#* and it didn't do anything, did you mean *#*#4636#*#*?

*#*#3282#*#* does not work for me but *#*#4636#*#* does. Is it because I have the Verizon variant?
Yeah, 3282 is most definitely a sprint thing
I can confirm that *#*#4636#*#* still works on Pixel 2 XL.

VoLTE not working

Hi, I had Poco F1 before with working VoLTE, so I know that my carrier and current Sim card is supporting it. All I had to do on the F1 was typing in that code *#*#86583#*#* and activating the new volte setting.
I tried that with the X3 but it's not working. Whenever I receive/make a phone call my connection will switch from 4G to 3G.
Is there a workaround or is it a hardware limitation? I could imagine because the X3 just has an entry level SOC that the modem has some artificial restrictions to differentiate from the flagship SOC (845/865).
Did you get a volte carrier check disabled message after dialling that?
For me both volte and vowifi are working fine
Yes I got that. Are you telling the phone your real location or do I have to chose India or china? I remember with my Poco F1 I had to chose India to get features like call recording...btw I'm in Australia.
Changing regions
Anyone know if I do a factory reset and change to a different region like Europe will that make the phone operate on different Verizon bands possibly allowing me to get service? Just a thought ?

If you got the VoLTE was disabled message after entering the code, go to SIM settings and there will show the option to activate VoLTE. If not appears, try to enter the code again and check the SIM settings.

I think using different bands it's more about regional ROMs construction (Global, India, Europe etc) than changing region in ROM settings. Alternative, you can flash a different regional ROM using MiFlash and see if it helps with your problem.
After entering that code I get the switch, to turn on volte, but that doesn't change anything.

Can't you see the specific VoLTE symbol near mobile signal in the upper right corner of the screen? If you can't see it, you can try to make a phone call and see if the google dialer shows it's a VoLTE call (or check the dialer history calls if you use Xiaomi dialer....you'll see there if it was a VoLTE call or not).
Same here with my Poco x3 NFC global I am on Vodafone UK my carrier support volte and vofi but I can't enable it , I have no settings . What I found when I flash custom ROMs the volte works , the sound in voice calls is super crisp and I got the icon always there vote on sim and vofi on WiFi . I need an option or a menu or a trick to show that option in stock ROM to enable it .
I remember back in the days when I had OnePlus I had to go in the ingineer menu to tick on a toggle " enable volte" and "enable vofi"
And later on the OnePlus 7t pro I had to install an apk to force that toggle so I can enable it .
On my Mi Mix 2s it shows volte when enabled. This one no. Poco needs to fix this before a number of users get dumped for lack of volte.

Did you try activate it using this codes in Dialer? VoLTE: *#*#86583#*#* and VoWIFI: *#*#869434#*#*. After that go to your SIM settings and you'll get the option to activate VoLTE and VoWiFi.
I have tried those and I left it on enabled both of them . Still not working

If you have an locked bootloader I'm not aware about a method to flash another regional ROM. I had read that many Poco X3 users have problems getting mobile data connection with Verizon (especially in USA).
Hello anyone has managed to operate the volte on both sim cards simultaneously on his POCO X3? thank you

Got my bootloader unlocked I'll try flash another regional rom
Same here in Italy, no volte, it switch ti 3g. With my previous 8t all was fine
I am using the stock room and used the dial codes got the settings but everytime I tried to make a call it wouldn't work I went to setting all specs and tap internal storage 5 times then choose the sim you are using then you have to turn the top switch off then back on. This is how I got mine working I also have extended my storage by using root explorer and cut everything under sd card and move to storage.

volte working ?

Does volte work on this phone straight out of the box, or do you need the eu rom to get it to work?
Need to use the service code to disable the carrier validation.

Yes, it works for me. I am on weekly 20.10.15. Of course i put code into dialer first to activate the VoLTE option.
But VoWiFi doesn't work at all.
Does 5G work?
Mine shows VoWiFI in the status bar but not sure if it's actually been used for a call, see top of screenshot

How you did it to get this icon? What is your version of MIUI release?
You can check is it working (or not) for callis in the dialer app on the call log. It should show the type of connection next to the data, time and duration of particular call.
Yes, but I rarely use SIM 2.
I am on the EU ROM and it and VoLTE are activated in the ROM with control from the SIM control page. See screenshot.

I understand that you are on EU ROM but what is your version? Stable or weekly? And what is the version number? (20.xx.xx)
For checking if VoWiFi works make a call and check the log in call log for call type, please.
I assume you have Mi 10 Ultra?
I have had both VoLTE and VoWiFI on every version of EU ROM 8 have used since coming from stock Chinese on both A10 and now A11 since launch. I'm on 20.11.05 this week. Both the most recent stable and all weeklies have had it working on the EU ROM.
Since A11, the option to have a preference of voice over Wi-fi or voice over LTE has dropped, you just get the option to turn on voice over LTE, looks like voice over Wi-fi is now preselected.
I understand that I can check my call log but I rarely use SIM 2, so cannot see any use of it on Wi-Fi in my current list and I am not making calls just to provide proof that it works. If 8t says so then I take it that it will. Why would the guys at Xiaomi EU bother to implement it if it doesn't work.
If you are not on the EU ROM, then get it flashed and if you don't like it, go back to stock and relock your bootloader. I bet once your here, I doubt if you will go back.
And although I checked yesterday and saw none, I did make a call and strangely it went out on SIM 2 as a VoWiFI call. See first line screenshot. Second line it never connected but top line shows the call over 4mins on VoWiFI. So it is fully implemented

Wow. Thanks.
That is strange. Me and other people cannot get it working.
I am on weekly 20.10.15.
And what type of Wi-Fi you have connected to? I mean 2.4GHz or 5GHz...
I am currently on a 5Ghz link at home but do get it out and about on 2.4 GHz too, I've never had an issue, see screenshot.
EDIT, just to show the VoLTE on mine, the second screenshot was taken away from the wi-fi, so shows VoLTE on the EU weekly ROM.

Hi folks
it seems I cannot find those codes, would you mind sharing a link (or the codes ) ? Are those two the same codes or different ones ?
I appreciate your help, thanks,

For VoWiFi you need to put code *#*#869434#*#* and after restart the phone set on VoWiFi in carrier configuration (tap on SIM card).

Question Wifi-Calling?

Greetings everyone!
Just got my Pixel 6a, love it so far, but i have one problem: Wifi Call doesnt work.
Whenever i try do a wifi call, i just get the message "out of network call"
Im using a german sim card from o2 (telefonica) and the thing is: my prior phone
was a redmi note 10 5g and with this phone (same sim card) wifi calling just worked like a charm.
so my question is: is there any trick to make it work? any explanation why it doesnt work with the 6a?
its a real bummer to go from a cheap a... redmi where this function just works fine to a nice and not so cheap pixel
(love google phones by the way, its my 3rd one), just to realize that something doesnt work as excpected.
i also tried a different os (calyx os), still no wifi-call.
help?

I'm using the Pixel 6a in Germany with o2 too - I've no issues with VoWifi and VoLTE. Are you shure you've enabled WLAN call in the accordant settings?
I use Google Voice...there an easier way w/o picking up an additional phone #?
On AT&T in the US...which is prolly why...lol

i wrote that i used wifi calling with the redmi just fine, so i guess i know how to set it up, yes. so far i tried two o2 cards, no luck. question is, can you (you) really do phone calls by wifi or are you just using cellular without actually knowing. can you still do phone calls when airplane mode is on but wifi is enabled? do you see the wifi-icon onscreen (below number/name you're calling) when making a call?

Hi,
I'm having similar issues with my Pixel 6a, also in Germany. I use it with two SIM cards (o2/Telefonica physical SIM card and Vodafone eSIM). I have enabled Wifi Calling in the SIM card settings for both SIM Cards, but _most_ of the time, it doesn't work. The phone tries to use placing calls over cellular (my home office is in my basement, so cellular reception is pretty bad to non-existent, especially with Vodafone)
Most of the times, because sometimes it does work, then it shows up in the status bar and the wifi symbol is shown when placing a call. I couldn't yet figure out any correlation to when or why it works or doesn't, I have tried restarting the phone, putting it to airplane mode, deactivating and re-activating Wifi-calling - or just using one SIM card.
I'd say ~90% of the time it doesn't work.
btw I have used a Pixel 4a with the exact same setup / SIM cards before and didn't experience any issue whatsoever.
Do you have any workaround in the meantime?
Not sure if this helps any, but when entering *#*#4636#*#* on dialpad, going into 'Phone Information'
Is WIFI Calling Provisioned enabled like in my attachment?

Thanks for your answer. It is enabled for both sim cards indeed, though (WLAN-Anrufe eingerichtet is the option in German).

Very welcome.
I'm sorry, I wish I was able to help with this!
I have found the error - it's actually caused by Blokada. I'm not sure whether it's just after some update of Blokada (I have used Blokada v5 for quite some time and regularly update) or the combination of Pixel 6a with Blokada, though. But Wifi calling always does work, when I disable Blokada.
Than I found this thread and have subsequently added com.android.phone and com.android.providers.telephony as bypass nad it does seem to work until now. Somebody else suggested bypass of Carrier provisioning service, I haven't tested yet, since as said it does seem to work now.
Just wanted to share my findings, if somebody else stumbles upon this thread.

Question Voice over Wifi - force activation?

Hello
I advised my brother to buy a Poco X4 Pro 5G as mi.com did a nice discount a few days ago.
The thing is, he lives in a place with very bad coverage so he is used to voice over wifi calls which work very well with his previous phone.
With the Poco X4 pro, it seems that his phone operator doesn't recognize this device as a compatible one (Orange, France).
Is there a way with stock MIUI to force voWifi activation?
Thanks
I haven't tried with VoWiFi but I have forced my Note 11Pro to use VoLTE and it works just fine.
I used the stock dialer and typed *#*#VOLTE#*#*
I guess you can try *#*#VOWIFI#*#*

Thanks you for your answer. Actually it concernes my brother's phone and he is doesn't live here and he is not as tech savvy as me so I just want to be sure about something before telling him to try : you can actually type letters with the stock dialer?? With MIUI 13?
Unfortunately I'm using an OP7T and I have no Xaiomi phone to try, and the xiaomi dialer apk is conflicting with the stock one on my phone so I can't simulate it.

No, you can't type letters with the dialer. You must type the numbers that correspond to those letters (each number has a bunch of letters beside it). So, what you should actually type is:
- For VoWiFi: *#*#869434#*#*
- For VoLTE: *#*#86583#*#*
These commands are toggles. So, if you type them again, you turn the feature off.
