VOLTE sim issue with Moto G 3rd gen

I recently got two sim cards of Reliance Jio 4G in India. This sim supports VOLTE for calling. I have put Jio 4G sim in slot 1 and Airtel 4G sim in slot 2. Things are working fine and I am getting LTE and VOLTE signals as shown in attached screenshot 1.

}
But at randomly, my LTE sim signal is getting lost and sim 1 is showing as in screenshot 2.
All I need to do is to go to sim settings and disable sim 1 and again enabling it will bring signals back. This is happening randomly during a day and happening 4-5 times in a day. I even dont know that signal is lost unless I take my phone of pocket for some other work. I have even tried to put second Jio 4G sim to check but same is happening with second sim also. Tried even putting both Jio 4G sim in sim slot 2 but same problem is happening. But my another sim of Airtel 4G is not having any such issue.
So I am confused whether its an issue with sim or phone? Not able to decide whether to go to service center or contact Jio service provider customer care.
Any help would really be appreciations. Thanks in advance.

Its the issue with jio 4g network
Its the issue with jio 4g, it is still under test and not commercially released, it is given only to reliance employees so that they can perform tests. I also have the SIM and I'm facing similar issues. So just chill nothing's wrong with your phone its the jio the network which is weak and under testing. But its getting stable day by day.
Also I wanted to ask you that how to use VoLTE as in my MOTO G3 this VoLTE symbol is not there? I was never able to make a VoLTE call. Is it because of the marshmallow update? Please let me know your software version. Are you on lollipop or marshmallow?
Thanks. :good:

I don't know how the OP is getting a VoLTE icon on their device, the Moto G 2015 does not support VoLTE.

Moto g 2015 support VoLTE , whatever version is your's LP or MM you have to just enable it in under settings.
Settings > More > Mobile networks > enhanced calling feature ( enable it ) .
Remember VoLTE is available only on sim 1 .

I don't see such option in the settings. No enchanced calling feature.......

Are you on stock ROM ? , if then your network service provider has to support VoLTE otherwise you can't enable it .

I am also using G3 and Jio4g ..I am not unable to listen the sound fron other side ..
There is no sound..
Please tell on which rom you were getting signals of VoLTE ??
Hint:- I am using Cm12.1 and there is no option to enable VoLte..

Only stock rom support VoLTE call and messages.
If you are on stock rom make sure you have enabled enhanced 4G LTE mode under mobile networks >settings.

I am using Reliance Jio 4G sim.Even I have faced the network disconnection issue sometimes.Hope it is the problem with the network provider(Reliance).Other than that everything is working fine,been using VOLTE for calls,and 4G is working smoothly for me as of now.

Did you recently updated to 6.0 ?
Will you check phone testing by dialing *#*#4636#*#* after check down there and select TURN ON VOLTE PROVISIONAL FLAG then reboot.
After that check in network settings.

its all issue of jio sim
I am also facing this type of issue my signal always lost when I change mobile data from jio to another sim

I used moto g3 with cm13
Faceing same problem !!
Use join jio app for calling maybe it works for you !!
But for me it's also not working !!

You cannot do that.
Jio4gvoice works only on your data.

Few Question

Hi just bought this device and I would like to ask few questions..
Is there a way to force activate VoLTE
If I register for the oppo account does it matter which region I choose if I want to use themes?
Also I suppose I have global version is there any way I can use theme store or download Themes?
Thanks

Sorry no, about themes you need the Chinese version for that.
And I might add it's nothing to write home about.
I have both, and the global works on volte when I cannot get a signal but have WiFi?

My Vodafone one supports hd voice and WiFi calling.
VoLTE is similar to HD Voice.

HD voice is also active on me but the thing is that when I call my LTE goes off

volte working ?

Does volte work on this phone straight out of the box, or do you need the eu rom to get it to work?

Need to use the service code to disable the carrier validation.

Yes, it works for me. I am on weekly 20.10.15. Of course i put code into dialer first to activate the VoLTE option.
But VoWiFi doesn't work at all.

Does 5G work?

Mine shows VoWiFI in the status bar but not sure if it's actually been used for a call, see top of screenshot

How you did it to get this icon? What is your version of MIUI release?
You can check is it working (or not) for callis in the dialer app on the call log. It should show the type of connection next to the data, time and duration of particular call.

Yes, but I rarely use SIM 2.
I am on the EU ROM and it and VoLTE are activated in the ROM with control from the SIM control page. See screenshot.

I understand that you are on EU ROM but what is your version? Stable or weekly? And what is the version number? (20.xx.xx)
For checking if VoWiFi works make a call and check the log in call log for call type, please.
I assume you have Mi 10 Ultra?

I have had both VoLTE and VoWiFI on every version of EU ROM 8 have used since coming from stock Chinese on both A10 and now A11 since launch. I'm on 20.11.05 this week. Both the most recent stable and all weeklies have had it working on the EU ROM.
Since A11, the option to have a preference of voice over Wi-fi or voice over LTE has dropped, you just get the option to turn on voice over LTE, looks like voice over Wi-fi is now preselected.
I understand that I can check my call log but I rarely use SIM 2, so cannot see any use of it on Wi-Fi in my current list and I am not making calls just to provide proof that it works. If 8t says so then I take it that it will. Why would the guys at Xiaomi EU bother to implement it if it doesn't work.
If you are not on the EU ROM, then get it flashed and if you don't like it, go back to stock and relock your bootloader. I bet once your here, I doubt if you will go back.

And although I checked yesterday and saw none, I did make a call and strangely it went out on SIM 2 as a VoWiFI call. See first line screenshot. Second line it never connected but top line shows the call over 4mins on VoWiFI. So it is fully implemented

Wow. Thanks.
That is strange. Me and other people cannot get it working.
I am on weekly 20.10.15.
And what type of Wi-Fi you have connected to? I mean 2.4GHz or 5GHz...

I am currently on a 5Ghz link at home but do get it out and about on 2.4 GHz too, I've never had an issue, see screenshot.
EDIT, just to show the VoLTE on mine, the second screenshot was taken away from the wi-fi, so shows VoLTE on the EU weekly ROM.

Hi folks
it seems I cannot find those codes, would you mind sharing a link (or the codes ) ? Are those two the same codes or different ones ?
I appreciate your help, thanks,
Axel

For VoWiFi you need to put code *#*#869434#*#* and after restart the phone set on VoWiFi in carrier configuration (tap on SIM card).
