small note

in order to enable port switch without any apk, just do following [needs root]

open adb connection in terminal and follow steps

adb devices
adb shell
su
setprop sys.usb.config diag,serial_cdev,rmnet,adb

the phone will disconnect from adb and PDC will be now available

wanted to post it in case OP blocks this apk way

^ This works
[OnePlus 7 Pro Questions & Answers] kk3296:
How about Volte?

Is it disable again?
[OnePlus 7 Pro Questions & Answers] sovi3tss:
Sorted]
[OnePlus 7 Pro Questions & Answers] dennis212:
Just checked my friend's 1+7P, *#801# still works although the update reset the profile to Oversea-Commercial_DS as usual. He set it to his desired profile no problem, I'm waiting for 9.5.8 for my base 1+7 to see if it's the same, the change-log seems the same as 9.5.11.

Edit. Used oxygen updater to get 9.5.8 *#801# still works. Interestingly Oversea-Commercial_DS came back even though I deleted it after the last update.
[OnePlus 7 Pro Questions & Answers] Paz9:
Nice!

Is this just for port switch? How about serial?
[OnePlus 7 Pro Questions & Answers] omrij:
Hi

used this guide since 9.5.4 and it worked perfectly

recently I've upgraded to DP4 an then went back to 9.5.11

now I can't find the VOLTE/VOWIFI switch under *#800 (it doesn't appear under function switch)

any solution?

HI. I used original post to do this on my 5T and 7Pro

Country: Israel

Carrier: 012mobile

Settings used: Telefonica_UK_Commercial

The VoLTE work without any problem but VoWIFI not :(

I tried 12-13 different profiles but nothing can't activate VoWIFI. And yes, the provider activated this option on all my accounts. Also, if I put my sim from 7Pro to 5T both options working.

Any idea how to get VoWIFI working ?

P.S. Today was OTA update for my 5T and it not restored versea-Commercial_DS profile to the list and both options still working ;)
[OnePlus 7 Pro Questions & Answers] sv8iik:
Also make restore factory settings and overseas profile didn't restore. Its missing from pdc. what must I do for restore?
[OnePlus 7 Pro Questions & Answers] ma678:
Try to flash the full zip firmware.
[OnePlus 7 Pro Questions & Answers] sv8iik:
can this done without loose apps and photos ? the steps for this are settings - system - system updates ?
[OnePlus 7 Pro Questions & Answers] ma678:
No, you will not. Download the full zip and local update.
[OnePlus 7 Pro Questions & Answers] sv8iik:
local update how to do please?
[OnePlus 7 Pro Questions & Answers] sv8iik:
I make local upgrade but overseas not appear . any ideas please ?
[OnePlus 7 Pro Questions & Answers] ma678:
Then I don't know. Local update always brings that profile back on my 6T.
[OnePlus 7 Pro Questions & Answers] brokieb:
Play Poland working, with india setting only ;)
[OnePlus 7 Pro Questions & Answers] Talixoli:
Yes. I can confirm that VoLTE and VoWiFi works only with France_Commercial_Orange for the RED SFR.

Update:

For the ones that have accidentally deleted the desired profile from PDC, you can recover it by locally upgrading your phone to the NEXT OS version. No MSMTOOL is necessary in this case. That means you need to wait for the update to be released, but in the meantime, you will not lose any of your data.

Doing a local upgrade to a currently installed OS version will not bring your removed profiles back.
[OnePlus 7 Pro Questions & Answers] sv8iik:
so no other way to recover deleted overseas profile?
[OnePlus 7 Pro Questions & Answers] Talixoli:
Flashing a clean OS with MSMTOOL or OS UPDATE via local upgrade are the only ways to recover deleted profiles that require no root. Someone suggested in this thread to fish out a file with all profiles from OS image, but I have no idea whether it will work or not.
[OnePlus 7 Pro Questions & Answers] sv8iik:
I made UPDATE via local upgrade but not have back the overseas profile
[OnePlus 7 Pro Questions & Answers] Talixoli:
If you do a local upgrade from 9.5.7 to 9.5.8, for example, it should work. It worked for me like a charm. All PDC changes were reset, and I got my deleted profile back.

But, if you will do a local upgrade from 9.5.7 to 9.5.7, it will not work.
[OnePlus 7 Pro Questions & Answers] sv8iik:
I made update from 9.5.11 to 9.5.11 . so I must wait until new update coming :(

Hi. Can you please confirm if VoLTE is still working on Ooredoo Qatar? I just tried but it did not work, neither India-VoLTE-Vodafone or Telefonica_UK_Commercial.

Also, did you remove "Oversea-Commercial_DS" or just disabled it? I didn't try to remove it yet, only disabled it.
[OnePlus 7 Pro Questions & Answers] psycoticninja:
has anyone tried this on a 6T? Need some help.

Installed everything fine, VoLTE + VoWiFi toggles are on using *#800# method, and phone connects fine to computer via USB (can't recognise on PDC) but once I switch on full-port switch and serial options via *#801#, the phone disconnects from USB completely.

Is there a way for custom ROMs? Or OOS is a must, and if not, can i force the volte then flash a custom ROM and then volte will work on the custom ROM?
[OnePlus 7 Pro Questions & Answers] salva52:
I have 2 questions :

One time that volte and vowifi are activated, can we disable Full-port switch and uninstall the apks "com.oem.oemlogkit_1.0-1" and "EngineerMode V1.01.0.171117173719" or not ?

Battery is more drained with volte and Vowifi ?

Thanks
[OnePlus 7 Pro Questions & Answers] proa_p:
You can.

Concerning the battery, I have no idea. I did not notice more or less drain when the reception is correct. I am in a zone without coverage so with vowifi actually saves me a lot of battery.

Yes, you need to install it otherwise your PC won't probably recognize the phone with PDC
[OnePlus 7 Pro Questions & Answers] omrij:
You probably need to register your phone for the service. VOWIFI works with 012 mobile network in Israel with both settings from OP (Vodafone India and Telefinica)
[OnePlus 7 Pro Questions & Answers] schturman:
I know this and it's activated on all my lines.

It work perfectly on my 5T, but on 7pro and 3 it show only VoLTE.

And yes, I already checked my sim from 7pro on 5T and VoWIFI activated and work perfectly. Only on 7pro and 3 icon of vowifi not appears.
[OnePlus 7 Pro Questions & Answers] omrij:
Which network? As I said it works for me with 012/Partner.

Unfortunately, VOLTE is disabled for few month in 012/partner so I can't check if this works.

Also, handover from VOWIFI to 3G doesn't work which make VOWIFI useless to me.
[OnePlus 7 Pro Questions & Answers] aldabubo:
I use 2 SIM, SIM 1 for voice and SIM 2 is data only. Voice SIM 1 does not have Internet access. There is VoLTE 2 in the notification bar. Can my phone use VoLTE 2 for voice SIM 1?
[OnePlus 7 Pro Questions & Answers] jcsww:
Depending on your carrier for SIM 1, VoLTE might need data enabled. T-Mobile's VoLTE requires a data connection to work.
[OnePlus 7 Pro Questions & Answers] aldabubo:
The problem is that when I turn on data on voice SIM 1, T-Mobile requires at least a 1.5GB tariff. Data SIM 2 has a 10GB tariff, so I don't need to pay 1.5GB. I would like VoLTE to work over data SIM 2. But it probably won't work.
[OnePlus 7 Pro Questions & Answers] jcsww:
You can't force VoLTE of one SIM over another SIM's data.

Another carrier in my country started supporting VoLTE, Safaricom. You have to use the USSD *100*12# to activate VoLTE for your sim card but otherwise it works with the ROW_Commercial profile alongside Faiba.

The VT switch in oneplus logkit switches on ViLTE but I've only had a successful video call Faiba to Faiba

[OnePlus 7 Pro Questions & Answers] Paz9:
phones have different requirements to using VOWIFI, connection strength, quality, etc etc.

i have a pixel 3xl and it uses vowifi 50% Of the time, even if my strength is 100% at times latency may be too high and it'd prefer VOLTE

if you go to an area with bad service and connect to the wifi im pretty sure youll be making more VOWIFI calls.

does your phone give you the option to prefer vowifi over volte? my 3XL did. My OP7Pro is sitting on my desk at home waiting to be set up.
