I just brought a One plus 3 last week.
I m using jio in sim slot 1 and bsnl in sim slot 2.
If I select cellular data on the Jio sim, both sims have network. But if I select cellular data on Bsnl sim, jio does not get network. I m using on oxygen OS 3.2.6.
It is hardware or software problem?

thats probably because jio is a 4g only network and oneplus 3 doesn't support both sims running 4g at the same time.

That doesn't matter, you can only set 4g network on the sim that has an active data connection. Suppose you have idea and Airtel and both have 4g, which ever sim is your data sim will be able to have 4g access.

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.
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.

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.

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
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..

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.

The volte option is now present but even if selected, the signal does not show it.

Cool. The 5G booster indeed enabled 5G! Thanks! - Though the speed is much worse than my newly bought S22+. 9RT got 4Mbps, S22+ got 150 Mbps.
Your referred logkit for VoLTE doesn't work for 9RT (could not install logkit for 9RT), see:
How to install logkit on 9RT
Does a logkit app exist for 9RT? On 9RT OxygenOS 11 A.05, dialing *#800# result a Feedback app instead of logkit. I tried latest logkit from following link, but first got "installing...", then got "App not installed"...
forum.xda-developers.com
Please let me know if you figure out a solution.
BTW: International sim card roaming ib AT&T has VoLTE settings in "Sim info & settings", but U.S. domestic AT&T/T-mobile sim cards do not have such settings.

I was getting over 350 Mbps once my 5G signal was working
Good to know that the roaming sim card has that option. It just sucks that we're limited with the fact that ours truly isn't a "global rom" but an Indian rom (as they still haven't released it elsewhere) and the choices like those activates for Indian carriers, afaik.
I've followed some telegram group for the 9rt and you're right, the current logkit doesn't work for the current OOS 11. Looks like we'll have to wait a bit longer.

Guy can anyone help me with my 1+9RT i bought it from AliExpress, it looses network signal randomly all the time. Sometimes has sometimes hasn't, can't use my phone. And also i can't call and nobody can't reach me by regular line either. Also when i use Wi-Fi it looses signal too. T-Mobile sim card i use as a main cellular carrier. Who has similar issues? Is anyone can help me?
Hi, anyone tried to change from oxygen to color os in order to have volte? regards
No. But i think its not going to help. Its because of the phone for China region. Not for United States. But maybe i am wrong.
hi all, i bought a 9rt witn oxygen (indian i believe), after reading for some time i realized not many people have this volte problem with color, so i with the help of oneplus china customer support went from oxygen to color, it solved my problem, volte from the start, no engineering mode or other thing to do, 4g and volte calls all right, i leave the post of instruccion for it..thanks to 4pda...
