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..
Hey guys,
Just yesterday I came to know of this annoying problem with our device. For context, I use Jio as SIM-1 and Airtel as SIM-2. So what I was trying to achieve is to use 4G data from SIM-2 while SIM-1 was 4G & VOLTE enabled. But the irritating thing is this configuration as far as I tried not possible. Even searched all over XDA and ZUK forums for our phone and still no solution. While SIM-1 is the Data SIM, SIM-2 can still be 4G (but what's the frickin purpose). But When SIM-2 is the Data SIM, SIM-1 can't be 4G or have VOLTE flag. Then I thought if this is problem might be over if I interchange the SIMs in the slots. Now SIM-1 is Airtel and SIM-2 is Jio. Now also if I set SIM-1 to be Data SIM, Jio doesn't receive any frickin signal or VOLTE Flag. If Someone can please help me solve this problem, it would be very much helpful. Or I would like to know whether this problem is with a particular ROM only. I Run RR 5.8.4 with latest basebands and Darkmoon Kernel. Please Someone Help me with this.
Bro it's the same for any phone none have dual 4g standby and as you switch data sims the Airtel switches to 4g while jio gets downgraded to 3g where it can't work properly

I can confirm that.
And also I've checked three other phones (Oneplus 2, Mi Max, Le 2) where the phones donot completely lose signal (though happens rarely but a reboot rectified it). I think this is more of a ROM based feature than a hardware incapability. If anyone can confirm that this particular configuration of SIMs work on any other phone(s), we could probably port that feature atleast as a Magisk Module.
This is not a phone or ROM problem...its just that jio doesnt want users to use free voice while they are using different carrier for data!
Mi a1 getting dual volte feature via new software updates, so can't we?
Dual volte is successfully implemented on mi a1 with software and ours is SD 820 I think we can also enable it

Most 4g have backward support 3g.. so even though the phone is latched on to 4g it is actually connected to 3g bands.. true volte is only jio.. if volte switch is off and you are still making calls then it's backwards 3g that is gsm network

For me jio is volte first sim and Vodafone LTE on second sim.
can someone confirm me if airtel VoLTE is supported in their z2 plus even on single sim? I asked customer support of airtel and they said that our phone does not support VoLTE feature of airtel.
I was purchase this G3 in Singapore and i need to use this phone in India. Because of new rule this sim only using voice call in VoLTE band (Jio). Any setting change will help to support me to use this Sim card? Or any custom ROM will have this feature in LG G3 ?
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..
VoLTE
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.
airtel volte

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.

Hi there :
I use dual sims on my 7T. from different carriers.
SIM1 only for voice call and on 3G network (in my place 3G has better signal than 4G)
SIM2 for DATA and on 4G .
when i do voice call by using SIM1, Sim2 drop to 3G and slow speed.(showing H or H+ on top bar. )
as in Australia non-carrier support VOLTE or VOWIFI on Oneplus 7T (or say all the oneplus phone base on my research),I can understand when voice call the network have to switch to 3G from 4G then go back after calls.
but in Dual Sim setup ,is it should be remain the network type and has same fast speed ?
Thanks in advance.
There's only one modem, so it can only do DSDS (dual sim, dual standby). When in a call, the other connection is dropped. This is why your data switches to sim1's 3G.
Are you intentionally trying to avoid using volte/vowifi for calls? If not, you likely need to do this: https://forum.xda-developers.com/oneplus-7t/how-to/volte-op7t-t4007085

Hi Thanks for your reply.
I see the reason. so DSDS can not support the way I want to use.
I tried the link you mentioned before. no luck.
In Australia, oneplus is not officially on market. So none of carrier support Volte on Oneplus.
My understanding is VoLTE and VOWIFI have to be supported by Carrier AND the Phone.
My oneplus 7T can open and use VOLTE when traveling overseas if I use local sim.
Our local forum have discuss this issue long time. No solution so far.
Some other phone like xiaomi or so can be supported in Australia. I was wonder why oneplus not.
Flash other country's rom may be ? Is there have a Volte international roaming thing ? So 7T can be pretended a Euro device roaming to Australia and using Volte ?
