WiFi Calling and VoLTE

Hi guys! I got OnePlus 6 (my first OP device) and I saw that on 5T there's WiFi Calling and VoLTE, but on OP6 is not and I couldn't find options to activate. I came from S8+ and I have both of them. Do you know something? There will be some updates about this? Thanks!

In your sim card/network settings in the op6 you should be able to find the option and enable them. With the networks I’m on I found I was able to do this.

That strongly depends on your carrier and the country you live in. In Germany, for example, VoLTE does not work with T-Mobile or Vodafone. In the US it does (T-Mobile).

Than you are the only person with german SIM and VoLTE working on OP6. In german Android Forum is a thread several pages long, where many people complain that OnePlus does not support it with a german SIM. Also the answer from an official ticket at OnePlus they answered they have no agreement with a german carrier.

Has it worked out of the box for you ?

I am in USA and looking to activate TMobile wifi calling and volte but don't see it in settings? Normally it's just there after I put my sim in past phones

Did you buy it from EE or from another carrier?
O2 has it in stock unlocked because it's dual sim, should work with ee?
Thank you

What carrier are you on? I'm on AT&T, so I don't have the option. I had to install the VoEnabler module via magisk. After a reboot the options are there, and working.

5.1.6 improves volte so that may help it has just started rolling out

It you font have this function in your SIM settings, just dial *#800#, then tap "oneplus Logkit", "Function Switch" and then tick VoLTE and VoWIFI Switch, reboot and voila...

Worked in Israel on Golan Telecom. I wonder why these options were invisible in the first place.

In Romania we have 2 carriers which support Volte, oneplus software dont have settings for it , i make to works for me like this its not my credit , i just found it on a german forum and it works like a charm :
https://android-hubo.de/thread/8127...te-vowifi-freischalten-de-ohne-root/?pageNo=1
1. MAKE a backup of the EFS partition over TWRP or ADB, and put it on safe place on computer or a cloud etc.
2. The Magisk module, must be installed: VoLTE / VoWiFi - Magisk modules
3. Install on your computer
Qualcomm QPST Diag x64 driver
QPST_2.7.460
4. Now you connect your mobile phone to the computer via a "USB cable"
5. Open the phone app and enter this code *#801#
6. Now a new menu appears and switches on "Serial" and "Full-port switch"
7. Start the program: "PDC" and connect it to your device
8. Right-click on "Oversea-Commercial_DS" under "Deactivate" and select "Sub0" and "Sub1"
9. Now press again on "Oversea-Commercial_DS" and below on Remove
10. Now select "India-VoLTE-Vodafone", right-click and select "SetSelectedConfig" "Sub0" and "Sub1"
11. Now press again on " India-VoLTE-Vodafone " and below on Activate
12. After you have done everything, restart the device!

Cricket USA

VoLTE

Could someone explain to me how it is possible?
In settings i don't have VoLTE option (Enhanced 4G/LTE mode) for on/off, VoLTE is available on my network in Croatia (Croatian Telecom) and IMS is registered.
But when I check with code *#*#4636#*#*, VoLTE provisioned is gray and cannot be enabled...

You are on June update?

Same here, though I am on the Telenor network in Norway. My carrier has opened up for it and it is enabled for my subscription in the network, but I can't activate VoLTE on my phone. Thought this option was going to be activated with the June update?

Well the same is for my network. As far as i know, your network provider needs to certify the device, this case our n7p, to be able to use volte. What you could do is perhaps reach out for support and ask them to make n7p certified

I asked them and they will certify Nokia devices sometime... But don't know how it works now and VoLTE is not enabled i device settings and cannot be enabled on Phone information (second screenshoot)?!

Well once they certified a device, there will be an OTA update that will enable it.

I don't see "Enhanced 4G LTE" mode in my sim setting. I am with Vodafone and they have VOLTE enabled. Any suggestion?

I've been having the same problem, here is what I found:
If you are willing to root your device, it appears to be possible to get VoLTE working: https://forum.xda-developers.com/nokia-7-plus/help/activate-volte-wifi-calling-nokia-7-plus-t3854829
Otherwise, wait for Google to implement a way to switch SIM profiles. The problem has been reported: https://issuetracker.google.com/issues/112570301
Edit: Nevermind, Google labeled the issues "Won't Fix (Obsolete)" and "Won't Fix (Infeasible)" two days ago. So its up to Nokia to implement a way to get VoLTE working, which I don't see happening soon. Apparently Googles answer is: Buy an Iphone if you want VoLTE outside the US.

Dont be so dramatic haha. I've got the Chinese model, running WW software in Australia and Volte through the flick of a switch and text message to my carrier. No problems here.

Good for you.
As far as I know, noone in Germany (perhabs even most of europe) has VoLTE on any unrooted Android One device. I have been bounced back and forth between the support of my provider and Nokia, they are both blaming the other party. And Googles answer to this obvious design flaw is: Won't fix.
So now its up to Nokia to create their own API in order to support VoLTE, i.e. providing their own version of Android. I don't thinks that was the point of the Android One program that I bought this device for.
So, while I was being hyperbolic, there aren't many options if you want VoLTE/VoWifi: Root your phone and void your waranty, buy a branded Samsung (some Motorola devices work too, I think), buy a Pixel and use it with a Google-partnered provider or buy an iPhone and use it with any provider you like. Wasn't too long ago that people switched to Android because iPhones only worked with specific carriers and people blamed Apple for bad policies. Now its the other way around, at least for this particular feature.

Wifi-Calling on T-mobile in US

Hi guys,
If i buy the 1+7 pro from their website, which i think is unlocked version, will it support wifi calling on tmobile network in US?
I understand tmobile has their own version, but based on their website review, it has tons of junk software preloaded and don't know why they removed the original screen protector, also locked bootloader, so im not too interested in that version....
I work in an area where there's basically no signal, so wifi calling is a must for me...now using a sony xz premium international version, basically can not make phone calls with it.
Thanks!

As long as you don't use a private DNS, it'll work. It's always worked on every OnePlus phone I've come in contact with.

Can you help explain this to me? I have the GSM Unlocked version.
Since yesterday I had the banner at the top showing VoLTE.
I wondered why it didn't show VoWifi while connected to my home network.
I literally did nothing except log into my T-Mobile account through my browser and the banner in my status bar switched to VoWifi, so I was like, oh cool!
But now, minutes later, the banner is gone altogether.
No VoLTE.
No VoWifi.
*Edit*
And now VoWifi is back

There's setting to enable these two in SIM card setting, a little hard to find...
That's the only thing I can think of, as mine as came enabled when received. Both work

I'm curious about LTE bands since you are on T-mobile in USA.
Can you confirm the phone support of bands 66 / 71 ? I've seen international specs that say the phone does and does not support these bands.
Edit 6/4/2019. I saw that you actually ordered a OnePlus 7 pro, and not a OnePlus 7... It does not appear that the OnePlus 7 supports bands 66 or 71, see https://forum.xda-developers.com/oneplus-7/help/one-plus-7-t3930123/page3

Question AT&T 5G - TS said it's possible?

Hey all,
With the 9 being on AT&T's approved list, I called it and asked if was possible to enable 5G on it and get things provisioned. CS and TS both looked at it and said everything's set up on their and and it's enabled on my SIM. Of course, 5G isn't a selection for radios.
I can "sort of" manually enable it in the engineering menu. Unfortunately, it doesn't work. And forcing it with the Network Guru (or whatever it was I saw in another forum) didn't seem to work either. However, I saw that there were people getting the Pixels working on 5G in countries where it was available but the phone wasn't supposed to work.
I'm running on the global rom. Does running the EU version have the option?

AT&T blocks it by IMEI number. It can't be overridden, people have tried and failed.

So. Theoretically I could put my fiance's daughter's Mint Mobile SIM in my OP9 to see if the 5g picks up, to test that?

Mint is T-Mobile. T-Mobile doesn't block 5G by device.

Question VoLTE and 5G - Pixel 7 on none supported countries

hello
My country (Poland) does not support pixel phones
I am only concern about VoLTE , is there any solution to enable it and not root phone ?
I have remember , there was some code just from google dialer

No

I ordered it already , hmm we will see

You would be one of the first ones to try
The Pixel 6 method could work perhaps since they are both Shannons

Edit: this needs root

This guy has my avatar with my name on it

I am waiting for confirmation if 7 Pro will work in Slovakia and I will be purchasing immediately. 6 Pro does not support 5G/VoLTE/VoWiFi in my country without root.

There's no reason to believe Google will finally enable worldwide 5G on their phones. Google is not a real smartphone brand, Pixel line is probably a showcase. Therefore, they seem to lack interest on better developing it.

I am a longtime Google phone user (nexus5, pixel1, pixel3, pixel5). If I am able to use VoLTE in Hungary, I will order a pixel 7.
Please post it here whoever has experience regarding global VoLTE support!
Thx

In Romania, also unsuported country no Volte on any of our carriers. Pixel 7pro

I managed to root my device and get 5G, VOLTE and call screening enabled on Pixel 7 in an unsupported country (Bahrain).
Let me know if u guys need a guide I will prepare one

How?

With T-Mobile from Czechia is VoLTE working. 5G not and I don't even care LTE is everywhere and more than fast enough

For me, it seems to be working out of the box in Hungary... Yet to test but in the menu, it's available

Sorry to jump on this thread but I've got an unbranded and unlocked Pixel 7 Pro and I'm using a pay monthly Vodafone UK sim card. I'm unable to find the method of turning on WiFi calling which would presumably be included in the Network And Internet settings had I purchased the phone direct from Vodafone.
I'm rooted, Can someone let me know what would be the best way of getting this option activated? Is there a Magisk or Xposed/Lsposed module that may force it? Vodafone UK definitely support it, the same sim card had WiFi calling working on my unbranded Note 10 Plus.

how do you know that VoLTE is disabled? Expect the VoLTE toggle will be hidden... Are you seeing the device fallback to 3G when trying to make a 4G call?

When I'm at home, my signal in some locations of my house is virtually non-existent. Previously, on my Note 10 Plus with the same sim card, WiFi Calling was a toggle in the network settings and, when on, I would have a clear notification icon on the status bar showing WiFi calling was in use when the phone was struggling to get a signal. I get no such notification on the Pixel nor is there a toggle when I've read elsewhere there should be.
voLTE isn't a concern, it's WiFi calling I want for when I'm at home.

I have just one simple question for Google...why do they ship the phone to non-supported countries from their official Amazon store?
Like...if you ship...make sure all features work?

Its not that Google doesn't support everything. Mobile carrier also need to implement device-specific attributes.

Google removed the WiFi calling icon a while ago in an android update or at least made it less visible. Would expect a toggle for wifi calling though in your call settings though. might be if it's not yet enabled, it'll come in a software update

People in non-supported countries still want a pixel device... VoLTE support isn't cheap or easy and Pixel is still growing
