VoLTE Support

Does this phone EVA-L09 support voice over LTE? I can't get it working and I can't find any settings for this? Every time I call someone the call gets routed through 3G and sometimes even 2G. I would like to have the supreme in call voice quality back, that I had on my OnePlus One.

Hi, have you found a way to enable the VoLTE?

No, but I think that my carrier is up to certifying the phone to the network so I'll have VoLTE soon.

With the Nougat B360 Update I can enable VoLTE via settings. I'm on Telekom DE.

How did you get 360? I'm still on 322.

Nice to see that, but this is the situation on mine
i am on 432b360 too. Have you activated it with some code or in some other way?
thanks

@africa89
No, I just did the Update and the Settings were there. Maybe VoLTE is something your provider has to enable? AFAIK the older contracts of T-Mobile didn't have VoLTE enabled, it had to be activated by the provider support helpline...

Can anyone or in any rom Volte will be activated ??

Can you post screenshot while making a phone call if it shows LTE or drops to H+??

Does wifi calling work?

An update on this matter...
As far as I can tell Huawei has been fixing one of their shortcomings and allowing VoLTE support on many more carriers despite the phone being the wrong reason.
I've heard from a reliable source that, although I didn't think it was true, indeed VoLTE works on T-Mobile US.
Note that this may or may not depend on the version/branding of the P20 Pro.
Wifi calling does not and has never worked on T-Mobile US with Huawei phones unfortunately.

This guy gets VOLTE on tmobile:

as best I can tell it works.. I make a call and band 12 stays connected throughout the call when VOLTE is enabled in settings.

Does 4G symbol remain while on call

Can you try this please?
1. Turn WiFi off.
2. Make sure 4G symbol is showing on your cellular bars at the top of the screen.
3. Make a phone call. You can even call 611 for T-MO customer service, and make sure that 4G symbol still remains while on the call and that it does not change to 3G or anything else? And if you can post a screenshot, it would be much appreciated.
Are you using the CLT-L29 and what region? European or Latin American version?

Correct it's the dual sim CLT-L29 Build Number is clt l29 8.1.0.106(c636)
That method of testing would be a step backward. I have already confirmed I am calling over Band 12. VOLTE is working, atleast for me on T-Mobile. I wasn't expecting it to from reviews but it was a nice surprise.

Thanks

I see your point and thank you so much for the info. Out of curiosity, are there WiFi calling settings showing up or no? That would be a double bonus.

A workaround to get WiFi calling is to download T-Mobile Digits from play store and you can use the app to make wifi calls. You may need to sign up for T-MOBILE Digits. I'm not sure. I was a beta tester for Digits and they since let me keep the service for free on 3 devices.

I've been using google voice / hangouts dialer (or whatever they want to call it this month) for a few years now. I hardly ever use T-mobile for calls, works out well when you want an international phone. Less reliance on the network features.
Out of curiosity do you remember if T-Mobile digits worked for incoming calls as well?

Yes it does work. And the fact that you can mimic one number or multiple numbers as many times as you'd like on multiple devices is pretty cool.

brother phone NEO-L29 Mate RS dual sim with sim t-mobile.pl i have options to VoLTE and WIFI calling

VoLTE definitely works and Wificalling menu is hidden. Don't think it works, yet but that might change at some point. Use a program like quickshortcutmaker and search for calling. The last option seems to be for att and the second from bottom is TMobile.

I believe that's because you are using an international phone in an international country on an international version of T-MO.

It must be supported by your telephone service provider so, check it firstly.

Mine is a Chinese version. The provider enabled voLTE for others smartphone like Samsung, Motorola. Is there another solution?

Follow this guide. It should work. https://forum.xda-developers.com/ma...ble-volte-icon-mobile-network-t3764826/page1/

If the provider has enabled volte support for your device it will work. It's just a setting in WiFi/ network menu. After that you ll see the corresponding icon on task bar.

Definitely worth talking to your service provider. Some providers don't support VOLTE on phones not bought directly from them. I bought my phone via Three UK. I don't have a VOLTE option and when I questioned this with Three support they said I didn't need an option as the service was always enabled and just a part of the standard Three offering.

Go to your network provider shop and ask them if they have enabled it for you .. You MAY BE need different packs .. or deals from Your OP
I just put EE-uk into Mate 9 (right) and it automatically showed option wifi-calling.. If I would remove EE sim it will goes away..
And there is calling over WiFi or 4G.. It is little bit weird that 4g network is packed in to wifi calling.. Which clearly is not
It should be separated option.. But it is just the way how wronlgy EE operator did it..
On the left it is P9 but I did it force way as it was patch applied because I was rebranding P9 to China and flashing oreo so patched VoLTE option.. It wasn't there previously in android 7

Here also. As a workaround you can disable VoLTE Carrier check (*#*#86583#*#*). This works at me.

For me it appeared in the settings with the update, but still cannot activate it

I have the same problem pls try
VoLTE *#*#86583#*#*
VoWIFI *#*#869434#*#*
It's work

For my case, VoLTE was operational before the upgrade (using 10.3.11 international version on my Mi9T in Vodafone GR). An icon was displayed for VoLTE on the carrier signal in my mobile's screen when it was connected in 4G.
Now it does not work anymore (upgraded yesterday to MIUI 11.0.1 international version, no icon when connected in 4G networks and actually drops to 3G when performing a call so it gets circtuit switched and not IP based via IMS). Of course it is not a matter of settings to disable carrier checks (as already done/undone several times, reboot etc, since it was in disabled state already and the settings are there to enable/disable VoLTE and VoWiFi).
VoWiFi still works but only when using Vodafone's application for WiFi calling.

Contact Vodafone GR (even their website and use chat to request VoWiFi/VoLTE service for your mobile number), they will handle it. Meanwhile you can also use *#*#VOLTE#*#* and *#*#VOWIFI#*#* settings to check that are in disabled state. You should be able to see VoLTE and VoWiFi settings (enable/disable etc) in your Sim cards & mobile settings (pick your Vodafone SIM settings then).

I have Vodafone in Italy the same problem but I wouldn't know how to insert the writing in the numeric keypad I just slip the symbols.

There're characters below the numbers.
Then *#*#VOLTE#*#* is keyed in as *#*#86583#*#*.

Hello ,

I am using only one sim card cosmote, so i can't check the dual 4g!
Thank u

Dialing the code "*#*#86583#*#*, the message "volte carrier check disabled" is shown. Then I can toggle the VoLTE option in settings, and it works when making a phone call. Look at the screenshots I attached.

Just returned from a trip to Thailand. VoLTE and ViWiFi work on both sim cards, Telekom (DE) and AIS (TH).
Cheers

Edit : VoLTE is activate...but don't work.....

Hi, I got a Mi 9 SE. I activated volte and wifi call with the codes under MIUI 10 some weeks ago. Volte and Wifi Call worked like a charm.
Now I received the Miui 11 update some days ago. Unfortunately Volte and Wificall stopped working.
Reentering the codes worked, but with enabling Carrier check again ...
Strange thing is that in settings the option to enable Volte and wifi call is still visible and activated - but I can't see the volte logo und it obviously doesnt't work ...
I read in another forum to do a factory reset might help --- but it got a lot of installed apps etc and I am not willing to reinstall everything ...
Anyone an idea how to reactivate?
Thanks for help!
