Access Hidden Menu - H915

*#546368#*915#
On the Canadian Freedom Mobile V20 even enabling LTE in the hidden menu, no LTE option available in Mobile Network settings. Apparently, we will get it in a firmware update in coming weeks.
And be careful, if you don't know what you're doing you can disable calling and mobile network access. If you do, try going into 'Field Test', 'Network Mode' and enable 'WCDMA AWS', or 'Automatic' if that doesn't work, should fix it.

This works on the H918

Yes, just use *#546368#*918# instead, 918 instead of 915. :highfive:

Thanks for the dialer code
Worked awesome on the H910!!!

Wi-Fi calling feature not available in Android Oreo build

Hi Dev’s,
I update my MIA1 to android oreo. When I search for Wi-Fi calling feature in settings, I notice that it is displayed. However when I click on Wi-Fi calling setting, It doesn’t dispaly under the Advanced Wifi settings.
My carrier supports Wi-Fi calling feature and I have it enables on my number. When I place the sim card in a iPhone, Wi-Fi calling works flawlessly. However it is not working in Mi A1 android oreo build.
Please can anyone help me get the setting activated on my mobile. I tried resetting the phone to factory settings, but I still don’t have the setting enabled.

Hi Yash,
Thanks for the reply.
I did search in the settings as suggested by you. I am able to see the Wi-Fi calling feature displayed in the search. However when I try to open the setting, it doesn't display. Please could post a screenshot of the setting from your Mi A1 mobile.

Did you figure it out?? I experience the same problem: WiFi calling appears appears in search but tapping on it opens WiFi settings menu with no WiFi calling option it it.

Hi,
I still couldn’t get to see the optionto enable or disable wi-fi calling in settings.
Howeve one of the oreo testers replied in an another thread that wi-fi calling option is available in oreo beta build. He also posted a screenshot that shows option to toggle on/off the setting. Please let me know if you figure out a way.

Screenshots. I don't think my TSP supports it. Its !dea.

Just clear the Settings app's data.

I can confirm that Wifi calling on Jio is not active yet on any network (JioFi's wifi calling is something else so please don't bring that up) as on date. I have tried this on a Mi A1 also which supports Wifi calling out-of-the-box.

WiFi calling isn't available at any TSP. ( In india)

I once tried to call someone when connected to WiFi. There was a pop up to enable wifi calling. I enabled it from there. Since then it didn't appear again. Also I can't test whether it's working because my carrier doesn't support wifi calling

[Guide]Enable VoLTE forcefully if Its not activated by default

As Title Speaks, Here is Little Workground for Enable VoLTE for OP6
Limitations :-
1. Sim Must be 4G Enabled.
2. You must Live under VoLTE Enabled Circle.
3.
Steps :-
1. Open Dialer
2. type USSD code *#*#4636#*#*
3. Select phone information
4. Now select Network type *LTE/UMTS auto(PRL)
5. Reboot..
6. Done
Go in Settings
Check if Both sim have VoLTE option Enabled
Also enable Data Roaming
Hope you get VoLTE..
I got VoLTE this way.. So just sharing..
Now Here is Bug with Vodafone VoLTE, when Trying to call, Network get bounced to 2G network.. It's Bug & Already reported to OnePlus..
If you still can't get VoLTE, Wait for Update.. ??

Doesn't work for me, no volte option under both sim settings and phone info switches back, TD-SCDMA/CDMA/UMTS

There should be VoLTE option for your sim..
If no, There is many chances that your SIM maybe not 4G ready or your circle don't have VoLTE feature..

Needs root but the only way I got it to work here is with the magisk module.

Ya, don't go playing with the band selection, or you may just get dropped to 2g connection with no LTE possible.
After digging around, I found a fix to get LTE back.
Download the "Network Signal Guru" app from the Play Store.
I told it to "Clear Forcings" in the menu, and LTE is back up.

Cantn find The Module can You give some more Informationen?

This won't work in Europe at least, no matter how Volte ready is your network/SIM card. OnePlus just ignores the issue.

This method https://forum.xda-developers.com/on...-volte-vowifi-german-carriers-t3817542/page28 works for activating VoLTE if your operator had enabled it for you.
I tried the method in the current post, but only got the toggles in the menu and not the real thing.
Had to call the mobile operator (Telenor BG, Bulgaria) to ask them to activate VoLTE and then did the method in the linked post.
I have a non-rooted OP6 and I'm now effectively using VoLTE on my network. Hope that helps.

Hmmm, does anybody know which was the previous default setting? I would like to revert it back and don't remember what setting was set before...

It doesn't work with Kuwait Viva !

If you want to get VoLTE and VoWiFi menu under SIM options in your OP6 just type *#800# in default dialer (not working in ther dialers) and under oneplus logkit>Function switch there is VoLTE and VoWiFi switch This is only to have that switch visible in menu so it isnt a guarantee that VoLTE will work on your device because your network carrier must support it and if it is not supported by carrier then VoLTE will not work no matter if you enable it with menu switch

Thanks, I used your guide and was able to enable VoLTE for my Vodafone.de LTE contract, my second card is from Sparhandy which is also I believe Vodafone but without LTE/4G, unfortunately VoWIFI is not showing up, I confirmed with Vodafone/LTE contract that it is enabled and it is, any suggestions?
TIA

somebody knows how to set up VoLTE on OOS9 ?
"Enhanced networking" missing for me

No one in Pie tried to set up VoLTE

VoLTE and VoWiFi just work, what setting up needs done?

Go to "Phone", Settings, SIM & Network Settings, then in to the SIM you want, and the VoLTE and WiFi calling is in there. It's NOT in the traditional Settings app.

jamal2367's method (see here in English: https://forum.xda-developers.com/oneplus-5t/how-to/guide-volte-vowifi-german-carriers-t3817542) works fine with OOS9/Pie.
Just updated & patched modem config with PDC as described in the link (I'm using the config "Telefonica_UK_Commercial" for O2 in Germany) and I'm up again with VoLTE/VoWifi working..
Still a shame that Oneplus is incapable to do enable the right config by default..

but it is just that in OOS9 you miss those switches what were in OOS5.11 in "Enhanced networking, this group is all missing in Pie

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.

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

Question 2G on A13

Can anyone who has already upgraded a Pixel 6a to A13 tell me if the "Allow 2G" option is still available in Settings-->Networks-->SIMs ?
Some people on twitter are saying that they cannot set 2G as a "preferred" network anymore, not sure what it implies.

The option is still here yes. However, you can't set 2G as the preferred network type.

Try this..
Open Dialer
type :- *#*#4636#*#*
Click on Phone info
Select Preferred Network type & Scroll Down & select "GSM Only"

Thank you guys.
Current situation is bizarre for me. I need 2G working for voice only. My carrier is switching 3G off, and I cannot have VoLTE working (despite the corresponding option being enabled and carrier saying that it should work). Currently, when I make a phone call, the 4G data connection gets disabled and voice travels over 3G or 2G. When the phone call is over, 4G data connection gets back on. Since 3G is being switched off, if 2G suddenly became totally unavailable, I simply couldn't make phone calls anymore.

I believe you can get a number with Google Voice, and call thru the app. I haven't used it in a while tho.

I used "Toggle Network Type" app on earlier android, but not it can't set 2G as preferred type anymore.
Edit: actually it was Automate app that I used, but neither it nor Toggle network type work.

Not sure if you have tried enabling this option in the SIM settings (something to do with the Tensor Security settings as Google deem 2G to be less secure.
