VoLTE support in stock or Custom ROM - G3 Q&A, Help & Troubleshooting

Hi,
I just got a sim that only supports LTE and VoLTE for calls and messages and basically any connectivity. So what I am looking for is a way to add VoLTE support to my LG G3 D855 32GB International Unlocked phone. It can be a stock ROM addition or a custom ROM, which supports it. Internet data connectivity works fine, just for the VoLTE part I have to use a custom app, which calls over the internet through LTE, but I'd like to have the VoLTE functionality integrated in the ROM. If someone has a solution then it'd be greatly appreciated.
Thanks!

First of all check if your phone is capable of VoLTE.. Most of snapdragon and Mtk phones are capable of it.. Second if it is capable then change modem/baseband as per the requirements of service provider. And some minor build.prop addition.. Then you may use Volte. Anyhow cm13 can be made volte capable..

VoLTE on AT&T

Does this work? Does anyone know how to enable it?
Great thread. I wonder if we can enable it because it does not work with any custom roms
It's been confirmed working on the pure nexus ROM. Check the development thread
It has not been confirmed working on att. I follow that thread closely. It's is working on Verizon and Tmobile.
I am running pure nexus with att and no volte

My apologies. I must've read it wrong then
Stu, do you have a VoLTE enabled SIM in your 5X? You have to have an account in the HSS and TAS to get an IMS registration...
I really don't know. Is volte working for you on att and the nexus 5? I don't think it can work but I hope I am wrong
Did you just pull the SIM from an existing phone? If so, was it a VoLTE phone? AT&T will only provision the SIM/Account for VoLTE if you have an approved device.
And no, I have not gotten my 5X to do VoLTE yet....working on it.
My friend just got Nexus 6P + new AT&T sim card. We made couple of calls and there is no VoLTE option in the cellular settings, as I have with my 5X on T-Mobile.
Remember that any VoLTE network is *completely* different than the existing CDMA/GSM/UMTS networks that the providers have. VoLTE utilizes an IMS or USP core that the phone has to register on to get VoLTE calls to work. The SIM information has to be defined within this IMS core, otherwise you will only get legacy services.
AT&T will currently only define a SIM for VoLTE is you have a certified device that they sell. But I already have VoLTE phones and am trying to use their SIMs without success. I think the 5X software may not be allowing the IMS registration. If you are on T-Mob I would call them up and see if they will provision your SIM for IMS....they don't seem to care about what phone you use.

VOLTE Question Concerning Fulmics ROM

My carrier, Three UK has recently rolled out Voice Over LTE (VOLTE) in the UK since the LG G3 supports VOLTE (Hardware wise since it supports 800 Mhz on the LTE Band). The only problem is it is currently only working for devices that run on the Three firmware and I have the unbranded European model. I have the firmware as a KDZ file and it works, however VOLTE doesn't work on Fulmics ROM 5.3 since when I make a call it switches to 3G instead of 4G.
Since the implementation of VOLTE is software based is there anyway to port it over to Fulmics ROM?
Any ideas?
Hmm I might be wrong but I do believe this is the correct functionality of VOLTE. The voice gets transferred over the 4G connection, and you get to keep the 3g internet connection active simlultaneasly.
Otherwise without having 4G you would just drop the data connection while having the call.

Sorry to hijack your thread, but would you mind telling me how to obtain the correct firmware?
Three's website doesn't offer a VoLTE compatible firmware for the G3, but offers the workaround of using the Three inTouch app. I don't want to use that, because reviews of the app are not promising.

VoLTE support

Hi guys,
I just wonder if M9 supports VoLTE calling. My carrier told me that HTC M9 will never support this function because I have to have stock rom literally from my Vodafone Czech carrier. But it seems to me that in that case nobody with alternative roms could use this function so my question is..does it support VoLTE if I will root my device and install some patch what I've seen here for volte support or do I have to install another Rom which supports VoLTE or any other ideas? Does my carrier have to really support precisely my model or is it just software issue on my side? I have newest Android 7 stock. Thanks for all replies!
Yes, the M9 absolutely supports VoLTE. Disclaimer: I have one on the desk next to me fully operational on a large carrier in the USA.
Given that, your network and your device work in unison to make the 'magic' work. You'll need an IMS APN programmed in the device, and one in the LTE network that validates the new default (signalling) bearer. My suggestion is to chat with a knowledgeable tech support rep. at your carrier, and be sure to ask if there's extra charge for the VoLTE. Since carriers understand that legacy circuit switched infrastructure has a limited future, they *should* be willing to move all your voice/SMS/MMS over to the IMS/LTE network they've invested in.
Best of luck.

Thanks for detail info. VoLTE is new in our country so I couldn't get any tech info even from my carrier. And I already found out that VoLTE isn't extra charged and even video calls are for the same price so that's great but I have to find precise info about IME apn setting. I hope somebody tell me precise settings. Thanks for info again!
Volte is carrier dependent. Both phones must be capable, both carriers must be capable. The problem is that Volte is not cross carrier at the moment so you and the person you're calling must both be on the SAME carrier, the carrier must be Volte capable, both with Volte compatible phones, both in a 4g signal area.
4g is a data only protocol with voice capabilities "patched" in to it. 4g was NEVER designed to carry voice signals so don't expect carriers to be in a hurry to implement Volte when 5g is just around the corner.
As to the answer to your question. Yes, The m9 is in fact Volte capable so it is purely down to the carrier investing in new technology. Carriers are NOT obliged to roll out Volte in any case. It is purely a case of demand vs supply. We already have a perfectly good 2g-3g infrastructure for voice and data so 4g only offers better data connections depending on signal strength. I think a lot of carriers are going to hold back for a while until the technology becomes proven or more so, an ISO standard is put in place.

Thanks for answer. My carrier already support VoLTE technology and we also have around 95% coverage of LTE infrastructure and I know both must have VoLTE support and LTE connection.
What I am trying to is use this technology if I am able to. My carrier told me it's not possible because my phone is old for it but I've read few articles that it's possible.
What I don't know if I need some option in settings (rom implemented settings) to activate it because I don't have any inside, on the other side when I go to cellular info through *#*#4636#*#* I have info about IMS and also about VoLTE what I can switch off.
So generally is it enough to find out how to setup IMS APN in settings to run VoLTE on my device or do I need also ROM which have implemented in settings VoLTE on/off?
Maybe I just don't get it correctly but I would like to have precise info what I need to get from my carrier to set up IMS APN on my device to run VoLTE if it's possible of course.
Hope it is understandable.
So no need to any special futures implemented in Android. It's enough to set up APN for IMS and LTE bearer.
The only device that needs adjusting for volte is the dev edition, i believe.
Otherwise this device is completely volte compatible. Maybe your carrier representative is confused..
Beamed in by telepathy.
So I finally talked with someone who knows more technical info from my carrier but he told me that it's all about radio bearers, channels of phone (don't know precise terminology) and my phone has to be unlocked for that channel, so it's kind of firmware problem because in our country isn't firmware unlocked for that channels yet. And nobody knows if it will be. Also each carrier has different channel for that and that's why it's incompatible with the same phone from another carrier.
I've seen also some utility to change that radio settings over PC with debugging mode on but don't know more info about it. So I guess I can try this for a last option.
If your phone is locked to carrier and branded then there is a possibility they've switched volte off but if your firmware region is 401 then your carrier rep is talking s**t as all 401 wwe (unbranded) phones are volte ready and it is the carrier who is lacking the technology.

Thank you, I don't have for now rooted M9, because I bough it recently and until now I tried to find out all option if it's possible in some way but I'll do it and try it later. Thank you very much for your help!
So I've tried and it doesn't work, no VoLTE , no Wi-Fi calling, so I am not sure what could be wrong. I can see setup in system and it's enabled but none of this works. Is there any log or anything what I can explore why it's not working? My carrier has a app for Wi-Fi calling so I wouldn't need it as a part of system but there could be setup which I need also for VoLTE if I get it right. Or is there any other flashable file for trying?

Hi Guys,
i have tried t-mobile rom for volte it worked great. also i notices that if i am changing firmware , volte is not working , as the volte options are still showned, when i get back to t-mobile firmware its worked. so i also searched that t-mobile rom has integrated IR92 lte support for volte, RCS integration and many things. Were i found that Verizon version has Integrated IR94 lte support for voice and video call over lte.

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.

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.

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

Not getting VoLTE on T-mobile on XT1710-06 version

Is or has anyone else been able to get VoLTE working on T-Mobile US on this model specifically? LTE and WiFi Calling work in general, but the "Enhanced 4G LTE Mode" toggle isn't there to allow VoLTE. The model has the same number of bands as the XT1710-01 model, but is on the RETLA channel, by the way.
Hi, actually I was having similar issues. VoLTE, seems to be different but is based on your Carrier mostly. If you call someone from a different carrier it may not be enabled. I'm with AT&T, whenever I call someone with AT&T and we are both with good 4g LTE, in the call, changes the status to HD. But, just with AT&T. At least that's how it Works for me. We should wait someone to confirm is this is how other carries behave.

Apologies for the late reply. Definitely no VoLTE or HD voice between me and other T-Mobile users. No matter what I tried it just never came up. If anyone's considering using this specific variant of the phone in the US, I'd be aware of the limits beforehand.

-06 is a North American dual sim variant, correct?
Are both SIM cards on t-mobile?
Could one use SIMS from different carriers?

-06 is a North American dual sim variant, correct. Updates should go through ATT Mex, I believe. And yes, you can use sims from other carriers. I used one sim card when I tried it and only utilized one of the sim slots as a result. T-Mo VoLTE just doesn't seem to have been certified for that variant.
So T-Mobile WIFI calling works on this variant of the Z2 Play? If so that is good to know especially when traveling overseas even if some other advanced features don't work.
I have an XT1710-06 retla device and I can confirm that wifi calling with T-mobile does *NOT* work on my device. There is a setting to enable wifi calling, but it never seems to connect and all calls still go over mobile. This is 100% testable if I for instance go into a deep basement that has wifi but no cellular signal -- I can browse the internet but cannot make phone calls or SMS, even though I have wifi calling turned on.
This is probably related to why VoLTE doesn't work either.
Also (as mentioned in another thread) still no updates for it past February 7.1.1 update. No later security updates and no Oreo updates.

Hi,
I'm super curious how did you get your Z2 Play to have VoLTE. I 've tried everything - new sim, IMEI of ATT branded phone, activated SIM on ATT phone, etc. , to no avail. I'm so frustrated and about to get another phone, because my HSPA signal is much weaker than LTE where I'm at and constantly have missed (straight to voicemail) or dropped calls. Please, let me know how did you get it to work.
Thanks
Maybe the problem is VolTE itself. As I tested. Unless both phones are with the same carrier and working good over 4G (good signal area) you can't get it working. At least in where I live that was true for a friend's phone and mine. So VolTE was good, until signal dropped hard. But impossible to work with other carriers.
Even it was good under Lineage OS and tested with Toxyc OS, but I saw the main thing is that 4G LTE should be firstly working fine. And same for anyone you call. Otherwise call will be normal. And for 4G LTE it depends on area support too.
Sorry for late reply

I have an XT1710-06 retla device and I can confirm that wifi calling with T-mobile does *NOT* work on my device. There is a setting to enable wifi calling, but it never seems to connect and all calls still go over mobile. This is 100% testable if I for instance go into a deep basement that has wifi but no cellular signal -- I can browse the internet but cannot make phone calls or SMS, even though I have wifi calling turned on.
This is probably related to why VoLTE doesn't work either.
Also (as mentioned in another thread) still no updates for it past February 7.1.1 update. No later security updates and no Oreo updates.

Same phone (XT1710-06 retla, rooted stock ROM on Oreo), and wifi calling on Tmobile also doesn't work for me. I can enable it in Settings, but I cannot send SMS or make calls over wifi with no cell service. After a while (a few hours) I get a Moto Settings notification that it can't enable Wifi calling, with a message underneath that says "Enabling." I can't dismiss the notification, only snooze it for up to 2 hours, and after I disable wifi calling it does eventually go away after a couple days.
Your problem is because none of the XT1710 variations have the 600MHz Band 71. It is the most recently added band and very few phones currently out there support it yet. As far as the HD voice issues mentioned...both people on the call have to be using a Volte supported phone and then HD automatically activates.
