Mate 9 from three U.K. Volte enabled but not working - Huawei Mate 9 Questions & Answers

I have a mate 9 bought from three U.K. . I'm in an area with volte supported. Volte option is switched on. But when I make a call the phone switch to 3G or H+
Someone know how to solve the problem and have volte working?
Thank you

I don't know, but I read that it needs an app from Three?

Hi
The app from three is just for wifi calling.
The volte option is on the phone settings and is present only when you put a three sim in. If I insert a ee sim the option for volte calling disappear...

No help?

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 :

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"

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!

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

Help can't switch off Volte on OnePlus 7 pro

Hi I bought a OnePlus 7 pro direct from OnePlus, I am on the EE network in the UK. I have issues where once I set up the phone Volte is active as shown in my status bar but there's no way to switch it off! I have looked in settings under sim and it has a WiFi calling toggle but nothing for Volte. I have also tried *#800# checked in logkit and there's no option there either! Is anyone else having this issue? Any help would be appreciated or I might have to return the device which I don't want to. Thanks in advance

Hey,
I bought the phone unlocked (from John Jewis) and put a 3 SIM in it so maybe there is a difference there?
I went to Settings, WiFi & Internet, SIM & Network, SIM 1 and I have a toggle there?

If you have a friend on another network, might be worth asking if you can put his/her sim in your phone and see if you have the VoLTE option on that sim card?
But yeah, otherwise it might be an issue specific to EE

Question ROG Phone 5 VOLTE AT&T Testing

Just figured in case anyone is curious regarding VOLTE on AT&T in the US.
To be clear, I have a "Global" variant of this phone. I believe its still technically a Japanese version? But it is an ROG variant and not a Tencent variant.
I am some what experienced with getting VOLTE on ROG Phone 2 as I was able to successfully. The good news is. VOLTE DOES work on AT&T. However, I had to activate it with *#*#3642623344#*#*
It doesn't show an icon on the top right that VoLTE is enabled, however, going into #*#*4636*#*# does show IMS is Registered and VoLTE is Available.
Calling does also sound like VoLTE is working and does stick on 4G during calls.
Cant seem to find the prop in ADB to always enable VOLTE yet, it seems different from ROG Phone 2.
Just thought I'd let anyone who is interested in the ROG Phone 5 and lives in the US.
I found something interesting. I Just followed the instructions that you did. After popping the sim card out and back in after enabling VoLTE the icon shows up in the status bar . I tried a reboot and it doesn't survive a reboot but it's a start in the right direction! Thank you!!!!

New Firmware gives me the VoLTE option on my phone without having to input that code. Update your phone (assuming its on WW Firmware) And you'll be good to go!

You dont have to be rooted for VOLTE to work. With the latest firmware it enables VoLTE without any kind of hack or user interaction. Haven't really gotten 5G to work but that might be due to where I am or I have to contact AT&T for it. but I do get 4G++ which Im guessing is close to 5G?

When I comment it's not release .
So we've established that VoLTE works on this phone with the latest firmware update. Can someone confirm that this means you can get this phone working on Verizon since they are decommissioning their CDMA network and that you'll need VoLTE to stay on the network?

I'm on the I005DC. However, the bands that I am able to use seem to be the US compatible bands as I currently see my phone using Band 12.
Did anyone's RCS break recently? Mine is stuck on "trying to verify".
UPDATE: After looking through logcat via adb, I've come to the conclusion that I've had too many provisioning attempts and am being rate-limited. I'll disable RCS for a week and hope it resets.

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).

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?

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
