a peculiar problem about VoLTE

hi all, i have a quite peculiar query about VoLTE on my 8 Pro.
i have 8 Pro for about 3 weeks now. i am using Airtel and Jio sims in it. both are 4G enabled. i am able to use Jio VoLTE without any problems since day 1 on this phone. Recently airtel started VoLTE in my region (Chhattisgarh) but i haven't been getting VoLTE option when i selected airtel as default sim for data. but when jio sim was selected as default data sim VoLTE was properly showing. i removed jio sim and tried again with airtel. still no VoLTE. i contacted airtel service center and they informed that it should be available in a day or two. so i waited for few days. meanwhile i saw a list of compatible handsets on airtel's website and there is no Huawei/Honor phone there. there are only handful phones which support airtel VoLTE.
after so many days of airtel launching VoLTE i am still unable to get it on my 8 pro. while looking for the solution i came across this information that airtel has to work with the device manufacturers so that the manufacturer can provide a software patch to enable airtel VoLTE compatibility, which is happening at a very slow rate.
now what i don't understand is that why does a device need a software patch for VoLTE compatibility with a certain specific network when the device is already VoLTE enabled.? i understand it is not specifically related with 8 Pro but i didn't have any other forum to ask this. thank you...

The volte support presently is just for jio. The software has to be updated to support airtel volte and that can only be done when honor releases an update.
Volte enabled handset doesn't mean that it will work for every service provider. There are certain files that needs to be added to the software. The modem files need to be updated.

can you please guide me towards any articles to know more about this?

You will ned updated firmware to support Airtel VoLTE. Besides you won't going to able volte on both sims simultaneously.
For now only two mediatek chipset support dual volte

i am aware that simultaneous 4g/VoLTE on both sims is not possible in most of the SoCs including Kirin 960, and that is not even my requirement. i am just curious to why firmware needs to be updated to support any particular network. if that's the normal behaviour of VoLTE then phone manufacturers should mention which networks are supported for VoLTE in their device specs.

No other careers uses VoLTE other than JIO( and now airtel in some states). That's why they configured it that way. When other career will launch VoLTE manufacturers will set it by default.
It is just like bios in pc motherboards. They update their bios to support new hardware.

that makes no sense whatsoever. if a device is 'xyz service' compatible without any region or network locking then that service should work out of the box. which network is offering which service is irrelevant for device manufacturers. it doesn't make any difference if all the networks provide any particular service or not, manufacturers' configurations ought to remain same.
and your pc motherboard analogy is completely irrelevant as well.

i have contacted Huawei and they have told me that they are currently in testing phase for airtel VoLTE, but that's not the issue at all. i appreciate your efforts but it would had been better if you actually understood what i was trying to ask here. thank you...

A Brief about VoLTE
Hi, so here's the thing. As you would be aware, VoLTE is just that, Voice over LTE. And, there's a reason as to why that terminology is used only for 4g (LTE) & not for 3g or 2g. 2g and 3g were developed with the concept of them being used for voice transmission whereas 4g (LTE) wasn't developed for simultaneous voice transmission. Hence, the term, VoLTE indicating that the voice part is an addition & not an integral part of LTE, bro.
By now, as you would have guessed, since voice is an addition, hence, there are no international standard protocols for it. Each Service Provider has their own protocols. Also, to support VoLTE, the Service Provider has to change its entire infrastructure. Hence, Airtel and Vodafone are rolling it in phases and are unable to do a national rollout.
So, to summarise, different Service Provider.....different protocols and hence, separate firmware and patches. And, to answer your final question regarding support for Jio. It's because at the time of development of most of the phones released in 2017, only data for Jio VoLTE was available and hence, the handsets are arriving with native support of Jio VoLTE
Hope, I have answered your query to your satisfaction

Huawei Honor view 10 is the only Honor device that has support for Airtel voLTE.
This is so sad that the mobile manufacturers take soooo long to work with operator and provide a patch update.
Most of the brands are more concerned about promoting their new mobile models and least concerned about giving updates to exisiting users

Need help to enable VoLTE in LG G7+ Thinq

I have purchased LG G7+ thinq Indian variant recently. I am facing issue with VoLTE for Airtel network. I am getting 4G but not volte. I didn't find any settings to enable it also. Can some one with Indian variant help me on VoLTE issue.

Reading the forum here I have tried flashing Singapore firmware but that didn't help...

Have the same problem here in mumbai.. airtel works only with 4g not volte.. whereas Jio volte works well.

Same case here..in India only JIO is supported..no other networks VOLTE is supported by this Flagship mobile of LG.
Somebody from India needs to call up their software update centre to develop and release updates for India as well....all most other regions have got at least the Sept updates.
Who knows..might be also possible that LG might soon exit from their Smart phone business in India like they had in China earlier this year..given it's dismal market share...if that's the case..no more updates..

Today got a firmware update and now VoLTE is working for Airtel Bangalore

How to get dual volte in Indian variant. I can use either Vodafone Internet or airtel at a time

Even I use Airtel( Mumbai), but it still shows 4g/4g+, not LTE above the signal bar. I have enabled Volte under mobile network option. What about other Airtel users?

Which region is this..? I am not getting the Volte next to my signal bar .. I'm using Airtel in Mumbai. Can you also post a screenshot without WiFi, just to see if LTE gets mentioned above the signal bar.

TURN OFF volte (*#*#4636#*#*)& also turn off volte for m mobile network, restart phone and now turn on volte from mobile network not from(*#*#4636#*#*), volte will get activated,strange but while making call network switches to (3g) h+.

Volte is licens based. Your operator have to pay for the licens to get it Working on every model.
So. Maby your operator havent bougt the licens for lg g7.

Airtel VoLTE works fine with 10t update. Volte was enabled for Vodafone, Idea, Airtel with that update. if you are using Indian specific EMW or EAW you shouldn't have any issue.

Yes 10t emw but no volte

Airtel, Kolkata.
The volte option is now present but even if selected, the signal does not show it.
As a matter of fact my phone doesn't even show 4g.

Airtel volte

hello friends is airtel volte supported for our p2?

Never seen a volte symbol while using airtel. It was fine with jio but I don't think it works with Airtel. I'm on lineage 15.1

EVR-L29 Enable VoLTE

Is it possible to enable VoLTE when it's not enabled by default. I just bought this phone and I don't see the setting.
Thank you

Settings-Cellular Network-Mobile Data.
However, it must be supported by your Provider, otherwise it will not be displayed.

It's not there...that's strange 20 Pro is supported but 20X isn't

Which Provider?
I use "3" in Austria.
With Yesss (A1) does not work but with "3" works.

Vodafone Czech Republic

It depends on simcard visit simcard customer care and replace simcard to volte enabled sim. Thats what i did when it didn't worked.

It worked on OnePlus 8 which I previously had. So I think sim card is not a problem

I have a Mate 20 with the same issue. VoLTE doesn't works on T-Mobile and is a software issue related to Huawei. Lots of people are having the same issue:
I Just made a post on Huawei Forums for see if we can report the issue. The more the people reports that increases the chances that this can be fixed:
​
https://consumer.huawei.com/en/community/details/topicId_120349/

Anyone get any clarity on this issue? I have AT&T in the United States and my IEMI was targeted for shut off today. After going a few rounds, they turned it back on but told me there was no way to prevent future pre-emptive shut offs because me EVR-L29 does calling over 3G which sends an automatic kill message. Further, as many have described, there is no switch to enable VoLTE in my settings. Are there other larger (7" plus) Chinese phones that are 4G LTE calling? Is there a way to address this issue with the EVR-L29? Thanks.

Did you receive a Welcome Offer from Jio that was sent to select users in new 5G locations?
See... https://www.dealntech.com/jio-5g/
Does your Jio plan include 5G?
