[VoLTE/VoWiFi][OP5/5T] for almost all carrier!

[jamal2367]

Hey!
I have found a way to activate VoLTE and VoWiFi for OnePlus 3/3T, 5/5T, 6 and 6T!

Please follow this Guide to Activate it to your Phone!

This is more for advanced users!

Greetings,

I'd like to let you know that this method also worked for me in Czech Republic for Vodafone. This guide probably works for most of the carriers in EU. Thanks!
Diese Methode hat auch in Tschechien funktioniert, ich kann nicht VoWiFi benutzen aber VoLTE funktioniert super. Wahrscheinlich funktioniert dieses Guide für alle Netzbetreiber in EU.

Why not sharing here, too?
Read something about EFS? Will it survuve, are there some modifications?
Thanks in advance.

It survives modem flashes and all. I'd write the whole procedure here but I'd need @jamal2367 permission to do so.

Hello,

tried here in belgium, when i click on "activate" it does nothing and when i click on start, nothing too.. Is there a validation message at the end of the procedure or not? thx

Working with Vodafone Portugal! Can't test a call just yet, I don't know anyone with a VoLTE device, but the icon appears.

From what I read on the forum, it's just the Magisk module for root users or the toolkit procedure for the ones without.
It does help with some carriers, but not everywhere =(

Thanks anyway!

And you have to modify your EFS ...
Read the OP on Hubo, he has an spoiler at the end.

Danke! I couldn't find it because Google Translate breaks everything.

Btw, could you modify your phone? I'm on step 7, but when I select my device, it gives me an error: "Failed to select interface with provided ID, please make sure interface still exist".

I did install the drivers and the QPST 2.7.420, did the *#801# and "Serial" + "Full-port switch" and I also tried removing and adding the port inside QPST Configuration and running QPST Software Download as Administrator.
The device is also shown under Ports in Device Manager (Windows 10).

Nothing worked...

Thanks!

Had the same issue, I rebooted my PC and that worked

This is at your own risk.

I am not responsible for broken phones, lost IMEI numbers, damaged EFS partition, whatever.



First make a backup of the EFS partition via TWRP or ADB, and back it up to a safe place on your computer!

WARNING: The EFS partition contains unique data for your device that is necessary for the phone function of your device. If you lose them, no one can help you out. So make a backup. If something goes wrong, you can restore the backup and you will be back to its original state.


2. you go to your computer and install both.
Qualcomm QPST Diag x64 driver

QPST_2.7.420


Now connect your mobile phone to your computer via a "USB cable".

4. opens the phone app and enter this code *#801#.


Now a new menu appears and switches "Serial" and "Full-port switch" on.


Now you start the program: "QPST Software Download" and connect it to your device.


Go to the "MCFG_PDC" tab at the top and select your device under "Device:".


Right-click on "Oversea-Commercial_DS" and select "Sub0" and "Sub1" under "Deactivate".


Now click on "Oversea-Commercial_DS" again and click on "Remove" on the right.


Now restart the program and go to the tab "MCFG_PDC" and under "Device:" select your device again.


Now select "Telefonica_UK_Commercial", right click and select "SetSelectedConfig" "Sub0" and "Sub1".


12. click on "Telefonica_UK_Commercial" then right click on "Activate" and then on "Start" below


13. after you have done everything, restart the device!

After a successful restart, the "VoLTE or VoWiFi logo" should appear in the expanded status bar.


No wonder why you dial "Telefonica_UK_Commercial", works great in Germany with all providers!

I wonder if this has the potential to fix the 3G issues as well, as we're effectively changing the modem's default profile it seems.

No lucky =( What's the name of the device that appears for you under MCFG_PDC tab?

Thank you!

It should be a long string of characters, IIRC. The name is unique to every device afaik.

Did someone tried this with French network ?

 

[xatou]

Is there any way to enable this on aosp rom?

I don't think so. Most AOSP rom's are missing some APN's. Ask the Dev if he implements all Google AOSP APN's.
