I am sharing my workaround to new JIO network.
If you are on MIUI, you are fine.
Those who are on custom ROM, or willing to flash these ROMs, especially on CM 13 based ROMs, keep reading.
Tested on CM 13 nightly (20160920).
Just to be on safe side
Insert JIO sim in SIM 1 slot and any other SIM in other slot. Make sure both SIMs are inserted.
Backup previous system.
Pull out SD card.
To get uninterrupted Jio service you need latest(Lollipop) modem and firmware on your device. To do that flash fastboot rom file.

Guide to flashing fastboot ROM-
http://en.miui.com/thread-307744-1-1.html
Let it boot.
Now you need to flash custom recovery(I am using TWRP).
GUIDE- http://en.miui.com/thread-249552-1-1.html
Flash any cm 13.0 based ROM and Gapps.
After setting everything it is possible that you are not getting any network of JIO.
As JIO is only 4G network. Choose only LTE in sim cards setting.
To do that head over to Settings-SIM cards- SIM 1 settings-preferred network type-LTE
Access point names(APN setting).
Name- Internet
APN- jionet
keep everything else as it is.
you don' need to install Jio4GVoice(previously named as JioJoin) app.
To make calls mobile data(JIO) should be ON at all time.
Hit Thanks.
It reboot every time when signal drops during call.
And it is likely to happen frequently as Jio signal is weak to penetrate wall!
I don't think for calling ,data have to on all time on cm 13.I can call without turning on data in cm 13 as it is volte supported.
How is the speed of downloads?? I am getting quite slow speeds afrer a day's use. Also data is on even after mobile data has been switched off from QS.
Unable to select jio4gvoice as default phone app,
While placing a call jio4gvoice redirects to system dialer.

This means your stock Dialer supports VoLTE( I checked this in Jio4G Voice app) so use stock Dialer
and In India many operators mainly Airtel, vodafone and Idea have rejected interconnection with Jio which results in outright call drop or the message that The network is busy and some of it is fault if Jio as they're increasing their customer base even when they haven't got fully operational servers. SO don't worry as its free in India and there should be some flaws in anything which is free(specially in India)
I didnt get VOlte in my Redmi CM13 custom ROM
i'm unable to use VOlte feature through normal dailerwhether i switched the data connection to ON or OFF .,the call basically disconnects

That means ur device is not volte supported.If u r using any custom rom and if there is a "HD" notification,then u can call by stock dialer.Otherwise u have to use jio4gcall apps
i tried a lot of cm13 based roms and aosp6.0 based roms, something seems to be wrong!! Previously the volte worked in the cm13 roms... now it doesn't... its like it only reverts back to kk bootloader or detects only kk bootloader although I installed miui lp.... Volte only works in miui lp for me! Any suggestion? Help required!
Search for my post in Redmi 2 Q&A. Working steps are detailed. Read them twice and you should get VoLTE

Dear Devs,
I was facing a problem related to Airplane Bug on Miui/CM7 roms, so i googled related to this but couldnot find anything of help. So thought of asking for your help..
1) Whenever i flash a stock or custom froyo/eclair/GB rom, it detects my network which is BSNL india without any problem
2) But when i flash any CM7 or ICS rom, my phone doesnot come out of Airplane mode at all..
3) So, i tried everything, but of no use.. IMEI is good ... nothing is corrupted
4) Yesterday, when i changed SIM card to other operators present in india, the airplane bug is gone
5) so i feel that problem is either with BSNL operator or may be with sim card as every other operators sim cards gets registered and there is no airplane bug there.. ( i tried Airtel/Docomo/Vodafone/Idea networks)
Is it do with RIL..
Kindly help me as this is same problem faced by so many people around globe with their operators..

Okay!!! So i'm not alone in this. I thought it was some other issue.
It's there with BSNL Network [ India ] . The radio doesn't turn on at all!. i flashed the JVT Modem as well ( Which works with samsung ROMs in the same network). The issue has been there since ICS Build 6/7 and MIUI also now. No networks showing. The radio is not turning on.
thank god!
I always thought it was my phone.
So it is an issue with BSNL.
please post a solution if there is any.
Thank you.
i had this problem with my phone a few times, i am living in turkey and i am with turkcell right now. i managed to solve it with a few steps:
1. turn on airplane mode from the settings page (not from the power menu). make sure you see the airplane logo in the status bar.
2. reboot to recovery and wipe cache only
3.when the phone boots up from recovery, turn off airplane mode from settings, and go to mobile networks page. select network operators. it will search for a while, go grab yourself a cup of coffee. after 5 minutes or so, wake up the phone and you will see the signal bars and phone is functional again!
u r not only who facing this problem ...
Hi .. i have same problem in BSNL .. while using CM/MIUI or CM based any rom ex: insanity rom .... even i m not able to solve airplane bug ... i searched a lot regarding this n read a lot .. there isnt any proper solution .. when i restart my phone sometimes No Service shows .. n that airplane mode still on ... i complained to Dev abt this ... and even about support for third party call recording software .. there is no solution yet .. ...
plz dev do something for issues ... we are huge fan of your rom ... and dont want to switch over any other rom ...
thanks ....
re-flashing same modem number of times do work some time..
pl you people and i also do trial and error to find best suited MIUI CM7 modem for India-BSNL
i was partially successful with jp5 here... Phone once detects network ... but on next boot... Network is gone again...
so...
flash different modems from recovery.. and if lucky enough.. can get network in 2nd or 3rd flash... ( you may also clear the cache)
please try different modems...
from this link... http://forum.xda-developers.com/showthread.php?t=1158783
lets post our findings here.. and find out best modem for INDIA
@all .... i m using MIUI ROM 1.11.25 has no problems from last month ... i got problem while i updated it .. then after there is no "No Service" problem ... try out guys ... it works like a charm .. i m using BSNL .. n dnt have problem ..
Are you subscribed to 3G services? It seems like the Samsung RIL implementation toggles to 2G mode quicker than Hacked RIL implementations that are on CM7 and MIUI which don't work so perfectly.
If you are not subscribed to 3G services, the phone would try to register on the 3G network upon Network Toggle or Airplane Toggle quite a while before actually switching to 2G. At this stage, you get the No Service bug which lasts quite long on CM7 or MIUI before getting back to 2G and getting a Network lock.
Have you tried using the 2G only mode and see if it gets better?
Unfortunately, RIL Implementations are properitary to Samsung and we won't be able to use them on AOSP based roms due to lack of source code.

Hi guys.
So a week ago my Mi5 only want to connect to edge, the LTE and 3G simply wont work.
I tryed everything, forcing it to only use LTE = No connection - same goes for 3G
I have also tryed to reset APN settings and nothing. I contacted my carrier, and they told me everything was fine.
I just tested it in my old Meizu and the LTE works fine. Anyone know what could cause it?
Please help, cause as for now the connection is so slow that without Wifi it might aswell be a flipphone...
Update: I also tryed to install a stable rom using this method: http://en.miui.com/a-232.html
But i cant, i get the "Your allowe to flash the newest stable rom from develop version ONLY"
Try this:
1. In Settings/About phone/ press several times on Internal memory
2. Press Phone information 1 or 2
3. Scroll down and Set Preffered network type as you see on image or chose LTE Ony .
4. Wait few seconds till change has effect.

You can try and flash another ROM to see if it's the roms problem, or do another clean (by wiping system,dalvik-cache,cache and data ofcourse) install of your current ROM. :good:

It could be the problem of your Sim network provider. Have you tested it out with other sim providers and see if you can place calls!?
Well in my case it somewhat worked with
*#*#4636#*#*
and then i select the GSM (PRL) and of the radio signal
now its working fine
now i want to know by switching of that radio signal will there be any other problem?
I had a Redmi 4x which when shipped had 8.2 MIUI version (Before some 3 months). That time I checked using Jio and VoLTE worked fine. Then, My mother was using it and now after certain auto updates it was on MIUI v8.5.4.0. I had ported her no to Jio (4G only network), and now VoLTE didn't work at all. I tried flashing Latest MM firmware. I even clean flashed MIUI9 Dev and even then VoLTE didn't work. Always IMS will not at all register (Checked via Phone info). I hence declared somehow Jio network block listed 4x (other countries models) but LTE used to work fine. Out of all hope, I tried Official RR with its own recommended FW and even then VoLTE was down..!! I even changed Device model (Redmi 4x to Redmi 4), still it was in vain. Even tried adding IMS in default AP. Some suggestion to Choose Home IMSI in SIM Toolkit will also not work because latest Jio SIM doesn't ship with SIM Toolkit option at all!!!
After full frustration and wasting one full day, I thought I should change the phone. But somehow suddenly it struck to try fastboot flash the oldest MIUI8 which device was booting initially. So after trying that, Voilaaaa! 1st time seeing VoLTE after long hours and late at night !!!
Somehow Now I flashed latest stable 8.5.4 MIUI and it also has VoLTE working. Even in custom ROMs VOLTE now is working. So yeah just to share my learning, to help people who are having tough time with VoLTE..! :highfive::highfive:

So I followed yr method & Yes i got my Volte back but now i'm stuck in Marshmallow and there's a bug with the screen auto rotate not functioning. I googled and found that many people who downgraded to MIUI 8 are facing this problem & there it was also written that wen they upgrade to MIUI 9 Nougat screen rotate functions are restored. So here's the thing me being from India need my Volte for Jio and after a long time finally got it to work...But if i upgrade to MIUI 9 Nougat i'm scared that i might lose my Volte again & have to start my previous process allover again starting with unlocking my bootloader as i have locked it while flashing it to MIUI 8. So my question to you is what did u mean when you said " Now I flashed latest stable 8.5.4 MIUI and it also has VoLTE working. " from here did u just did OTA update (coz i'm getting V8.5.2.0 MAMMIED Update via my updater app). Or did u use Fastboot flash to 8.5.4 MIUI .??
BTW I was thinking should i just download a update.zip of the latest stable global V9.2 Rom & flashed it via the Updater App using update package option.. skipping v8.5.2.0 & other minor Updates and just jump to the latest. Will i still have Volte working on my Phone if i update to MIUI 9.
I'm Confused.....Pliz Help
Thanks In Advance.

Hi., I unlocked bootloader and I used fastboot method to go back to prev version. Once the volte worked, MIUI9 also got VoLTE working. So try clean flashing latest MiUi and VoLTE would still work...

By clean flashing do u mean fastboot method or update.zip recovery method.....
U see I'm confused as there are many forms of flashing so it fastboot method with miflash right!!.
Ok I will try to download this fastboot stable rom for miui 9.... let's see how it goes.
Thanks a lot...
Damn this phone really is high maintenance...

So I tried and guess what it didn't work. Volte is confirmed to be working only in marshmallow miui8 and as we try to jump to nougat miui9 volte just doesn't work. So i flashed back to marshmallow and then did ota update ( minor 350mb update) which is still Android 6 and volte still works now I get ota update for miui 9 but I'm not willing to jump the gun anymore......
Maybe if I do ota update to miui9 after getting volte maybe it could miraculously get it's volte back but having flashed the phone multiple times and since I need to use this phone I'm gonna stop here so we'll never know if volte is ever gonna work in miui9 via ota...
Btw even if I got volte back the gyro and screen rotation is not working both in the old marshmallow and in the recently updated ota marshmallow. So playing some gyro games and having the gallery to open pics in auto rotate is out of the question.
I even tried flashing persist.img via both fastboot and miflash method & while it didn't allow me to erase and write the persist.img even though my bootloader is unlocked in fastboot method. I did managed to flash it via miflash tool after editing some .bat files via notepad++ so that I only flash the persist.img and not the whole rom.
There's a whole tutorial about this too on Google and guess what again this methods didn't do anything and I have both gyro and auto rotate not functioning.
It will function in miui 9 but in that version we'll know that volte doesn't work so....
My only conclusion is that without Xiaomi dev patching it out there's just no way this bug can be solved by simple flashing as in either form of the OS one ends up sacrificing one function or the other.
Btw thanks for replying, helping and hearing me out...
Really appreciate it.

This whole VoLTE concept more or less isnt as reliable as legacy 2g/3G calls. Even yesterday for some wierd reason, VoLTE in this phone didn't work. I swapped SIM to another VoLTE where it didn't work on it too. I just let it for half day after which it started working. There isn't one proper way when on rooted phones, to easily get VoLTE related log data, so that we can try fixing the rootcause. Anyways I'm glad somehow you are able to manage...
My Volte working with miui 9 stable roms
Pliz give detailed description.
I'm excited to hear about this.
Btw no offence but you are sure that yr device is Redmi 4X and not Redmi 4, right!!
try to change your location in additional setting from your system location to another location, ex: thailand, and then check your volte setting
Ok that thought never occurred to me but I will not go back to miui 9 for the time being but if I do in the future I will definitely apply this method to check the volte.
Thanks for sharing this idea
Is volte working for any of you in pie roms?
Not Working
I got my redmi 4x from china ;-; works on marshmallow and goes off in nougat (miui) , Custom ROM (all nougat roms works fine with volte) but no volte in Oreo as well as in Pie.. Maybe Locked Bands
Same for me.

Volte never worked for me on custom roms( oreo or pie). Currently on Arrow os (Pie). Tired everything but never got Volte working. It would be great relief for me if i would see volte sign on custom rom.
Hey guys! My Le-X526 is not able to send or recieve SMS at all. It was previously not working only with Jio but was working fine with airtel, now it isn’t working on both. Airtel still receives but when I try to send the balance is deducted and it says sent but I don’t receive the message on other phone and sometimes it straight shows up not sent and on jio? Completely blocked both ways. Nor does it receive any message nor does it send. I’ve tried various custom roms until now, flashed the 19s bootloader but it’s still the same, nothing wrong with the apn settings. VoLTE is working fine, mobile data is and so are calls.
What must’ve caused this guys? Is it hardware problem or did I **** up somewhere? It was working all fine before, it just happened out of blue.
What should I do?
Should I go back to stock? HELP PLS :crying:
Solved for me.
I installed stock, dialled *#*#4636#*#*.
Chose sim 0 or 1 (jio)
Enable option called SMS over SMP Or something.
At end update smsc number.
Voila.
Done.
Enjoy.
Not gonna find in custom ROM s dialer. So try n fix in stock ROM n then move to custom ROM.
I met a similar problem before, then I flash 2 different stock roms and it works again.
