Using Reliance JIO 4G sim on the Oneplus 3

So I purchased a Reliance Jio sim for my phone. Thing is, it works perfectly fine on Oxygen OS. It did work properly on CM based roms initially, but now it connects, however in a weird way. I can send and receive messages on whatsapp and fb messenger. The sim icon shows the LTE symbol with the "!" sign next to it. Like as if it's not properly connected to the network, I'd say. However, on reflashing Oxygen, the sim worked perfectly fine. Any help? The sim does work in the Band 40, but still i have the problem mentioned above. It's really frustrating as i'd like to stay on cm. Are there any work arounds? Would flashing the stock modem over a custom rom help? Would that affect the performance of a custom rom in anyway?? Thanks in advance!

Sorry I do not have answer but have the exact same question. Also, I have additional ones: even with Oxygen OS, did Jio work from *both* SIM slots (or only slot 1)? Did you make voice call by VoLTE (or Jio's app)? I too want to move to CM as soon as everything works.

Well, i didn't try it from the second slot on Oxygen, but i did on CM13. The signal was full, and i am sure it'd work. I haven't tried the VoLTE feature properly yet, so i cannot comment. And i actually ended up finding a solution to my own problem, where in there was a proxy which was triggered in the apn. God knows how that happened. Anyway, it'd be helpful if anyone else who has experienced problems could offer some advice. Cheers!

they should work. I did not test those builds out because i wanted to use the oxygen OS camera port. It does work in the official RR, but as i downloaded the blackjubel build, i figured i don't need to test the official one for now. I used to use it before and it's an awesome rom. As for sultan's rom, loved the build, but my desire to use the stock oxygen camera made me stick with official CM.

In settings, go to sim cards. You'll see sim 1 and sim 2 settings. Depending on which slot your jio is in, select that accordingly. You can see the option for APNs there.

Actually there were no APN s .. So I created one. Now data is working

As Jio sim uses 4G data for everything that includes voice, sms and data, it is very crucial that u have a proper APN for the sim.
Name: Jio or Jio4G
APN : jionet
Server : just type 3w dot Google dot com
Authentication Type : None
APN Type : default,supl
APN Protocol : IPv4/IPv6
APN Rising Protocol : IPv4/IPv6
Beater : unspecified
Create a new APN with the following settings and than u can either restart the phone or just set airplane mode and than back to normal.

I get the icon in the in call UI. The VoLTE icon appears while using Oxygen OS. Try using the Jio App, one of them is purely meant for VoLTE

I was having a similar problem when I flashed art97 rom (I might have the name wrong but it's similar to that). I have tried other custom ROMs based on CM13 (like resurrection rom) and VoLTE does show up.

[HELP] VoLTE issue

Jio sim user here. Everything was fine until I decided to move to another ROM from Community Build. Found that VoLTE is not working on any other ROM, not even Oxygen stock. I tried locking bootloader and going back completely to stock but still VoLTE is dead. Don't know what I messed up but any help would be appreciated.

if you don't have a proper reply please don't comment. I asked about VoLTE not the Jio app. I know I can use it too.

At the moment no other Marshmallow ROM for the oneplus 3 supports VoLTE by itself expect the Community Builds. All 7.0 Nougat ROMs do give VoLTE support. I myslef am on AOKP N.
Flash a Nougat ROM and you'll get back your VoLTE.

I'm on CB 3.5.3 and I can't see VoLTE settings, here two pictures:
What's the problem?

Is the "Enhanced 4G LTE Mode" On under the Cellular networks setting?

No, I haven't.

VoLTE work around on stock / CB
Clean Flash Stock / CB rom using twrp .
You first have to extract 4 files contained in the zip file attached .
Now make a efs backup from twrp
Now go in twrp>backups>device serial number folder>the most recent backup you made folder
And paste the 4 files and replace them with your efs files Then restore EFS back up only using twrp.
That worked for my friend on 3.2.6 stock who completely lost VoLTE , tried every thing found this solution by hit and trail hope it works for you as well.

Misleading

I can't find the cellular network settings options after the nougat update on my OnePlus 3

Did you try stock Nougat? I can no longer see the 'VoLTE' icon in Nougat but voice calls work fine without the need of any app. In Marshmallow VoLTE icon used to appear. If you see '"Enhanced 4G LTE Mode" option in cellular settings menu VoLTE should work.

Maybe im selecting the wrong option but even though i ticked the enhanced lte option im still not getting VoLte on nougat.
As soon as I initiate a call it automatically drops to 3g.

Strange. Not sure why it is happening so. I got a Nexus 5x running Nougat too and it also doesn't show any VoLTE icon but everything works fine. Data, VoLTE calls etc.

VOLTE on Reliance Jio

Can someone please help me with enabling VOLTE on my OP3 running akhil narang's latest RR build. It stays on LTE and calls through Jio don't connect. I have enhanced LTE enabled and also tried editing build prop. please help.

Flash oos or open beta first. Boot up completely. U will have volte enabled. Then flash the custom ROM ..
There is an issue with custom roms .. none of them can initialise IMS properly and registration fails. However if you flash the stock oos or open beta first, the IMS registration works. And I suppose, it just sticks when you boot the next time with a custom rom.
Don't ask me the reason. It just works for me this way everytime without a fail.

Yeah you need to clean flash. Both. First clean flash oos/ob. Then clean flash custom ROM.
My theory is that it has to do with the firmware. So if you stay on the same firmware when moving from oos/ob to custom ROM, then volte should work fine. If you flash a different firmware then the custom ROM will not be able to initiate and complete the IMS registeration ... But as I said just a theory

Why dont you just try flashing the latest firmware which is recommended for your ROM..??

I've the same problem and I am having airtel volte. It doesn't work on any custom rom but as I move on OOS is just works fine. I am currently on Oxygen OS beta 27. I'll try your method . what all the things I have to wipe before flashing custom ROM ? And also should I flash again the firmware?

First check if Airtel volte is supported by the custom ROM.
If yes then try wiping system, data and cache.
No need to flash firmware

Custom roms dont really support carriers persay. Most roms dont support VOLTE, at least not the India based carriers. Best bet would be look for one that supports VOLTE on T-mobile and see if you can work with the dev. Other then that you will be hard pressed to find one that work with India VOLTE. Its just not something that is tested or cared about by most developers.

I think it's firmware related.So flash the latest Indian firmware.Also Try roms developed by Indian devs.They will try to support all carriers in India.

That will be a problem as most of the devs on different teams are not from India nor are they willing to add closed sourced code just to get something working that only one country uses.

So devs i humbly request you to find solution for this issue...

Ya its a big issue in using Oreo rom. I am back to Lineage os 14.1 .

VoLTE is a PIA for developer's. not just because the code is proprietary (meaning no access to the source code).
the Dev's so far have not focused to fix VoLTE for Oreo hence the issues. they focus on other major more important fixes first.
Oreo is a major re-write to C++ compared to Nougat.
VoLTE on 14.1 is stable because the Dev's have figured out a proper way to make it work. Which is not yet the case with Oreo. so if you want stable VoLTE stick with Official LOS 14.1.

How to flash stock modem .
I am on AEX.
---------- Post added at 07:50 AM ---------- Previous post was at 07:46 AM ----------
I think AOSP roms have volte problems.
When I am on AOKP os volte working fine..
Yesterday I flashed AEX which is based on AOSP.
Volte gone.

One way to get back the volte is by changing the sim card from 1 to 2 or vice versa. This will get you volte. And then if you want to change the sim cards back to original then do so. The volte will stick.
Other one is, flash the stock ROM modem or an LOS modem. It worked for me with stock and RR modem.

maximum all ROMs have volte enabled. if you're in roaming then you need to set ims settings in access point. and if you're not in roaming then you need to flash volte enabler zip present for lenovo p2. just search it

Which RR ROM did you install mate? I'm finding LOS 14.1 performance is sluggish and I'm experiencing kernel wakelock battery drains as well.
Keen to move to another ROM and kernel if necessary.
