Only one sim receives signal at a time

Hi,
So everything was working fine, unless I decided to explore a bit and messed up. I dialed *#*#4636#*#* and turned off data. Then i turned it on and maybe i also changed some band and boom. Now only sim 2 is receiving signal. When i take out sim 2, then sim 1 works perfectly. I played more with phone information and then suddenly sim 1 started working but sim 2 stopped receiving signals. So in short, only one sim receives signal at a time.
Any leads on how to solve this? Have already done a factory reset and wiped off the cache, but to no help.
Android version - 6.0.1
OS version - 3.0.2
Regards,

Hello tushar, I'm really sorry about that. Unfortunately i did the same thing and m receiving signal in one of the sim but never together. Its been a week for me and no solution. I really hope someone can provide us with an answer.

Finally......
Hello guys i solved this issue by flashing oxygen os 2.2.0 now my both sim are working fine.
Just flash oxygen os 2.2.0 which has dual SIM preference selection fix.

Facing error in Redmi 2 Prime 20140818

I have been facing a problem in my Redmi 2 Prime, whenever i switch data sim from SIM 1 to SIM 2 the signal for both SIM goes off and it shows no Service or No SIM Card, even while it's inserted, tried and working on other phones, I have Jio 4G Sim(Blank SIM) in slot 1 and reliance GSM in Sim 2 and if SIM 1 is selected as data SIM, then it works with 2g Signal, but when switching to SIM 2(for Data) No Service or NO SIM CARD is shown, tried also by removing either of the SIMs from the slots, but if Reliance remain in SIM2 then i face same issue, sometimes it works on removing sims and restarting my device several times previously on MIUI8 global Beta, i have tried:
1. Downgrading to MIUI 7.5.3.0 - same problem faced
2. Installed CM13- resulting in bootloop if SIM 2 is selected for data
3. Mokee 60.1-release - Same problem as in CM13
All other things are working
Do I have to go to service center or is there any solution like custom Kernel
Please reply ASAP as Redmi 2 Prime is my daily driver as of now

Done fastboot, but its of no use. I flashed CM13 again. Now SIM 1 slot is working but if i insert SIM in Slot 2, Its entering bootloop. I tried swapping sims but still bootloop. If I put SIM in slot 1 its working. Also if I am inserting my JIO SIM in slot 1, its entering bootloop.

faced same issue
yesterday i got repaired for INR 230 problem solved
i asked them what u did they told we use online mi tool
i asked it because i flashed fastboot rom but not worked
now am afraid to insert jio sim
am on 7.5.2.0 can i insert the sim
plz any one help

Yeah, Happening with me too. Also when I place a call on VoLTE reboot occurs on custom rom and network disappears of both sim in MIUI. IDK why it is hapenning. I have also tried clean flashing stock MIUI using fastboot but it still happens. Any solution will be appreciated!

Try booting up without any sim cards inserted after flashing any custom ROM. Jio SIM functions properly as long as it is selected as the data SIM. Otherwise it creates a lot of problem. As for ROMs, try RR 5.8.3 or AEX 4.0.

It happens with moto g3...i guess other phones face this issue with jio sim...there's no fix for it yet...stick with miui as it only lose network for few seconds instead of rebooting phone...it happens where low network coverage...

Volte is fixed on miui 8 global beta 6.9.9!

Many user are facing problem to enable Volte in new 6.9.9 update.
To fix it You need to insert your sim card ,
Re-enable Volte and reboot your phone,after reboot it will work.
If it doesn't work on first reboot ,i sugget to reboot 2-3 times.
Its working i have personally tested it and other many users enabled Volte by this method.
I am attaching screenshot too!
Post you status below it worked or not?

Sometimes just taking sim out, booting up and power off and putting back sim works. I had similar experience with LP ROMs which had VoLTE available bit not working.

I dont know how to fix it,i suggest do a clean installation of rom again via twrp

I flashed 6.9.9. but Im stuck at couldnt check find device status. Anyone know anyway to bypass or remove it?

Another solution to get VoLTE working is, delete the default APN, reboot and manually add the APN. Then turn on VoLTE. It should work.

VoLte Fix for MIUI :
- Delete APN jionet in settings
- Turnoff mobile data and volte in settings for reliance JIO
- Turn Off JIO sim and Turn On again
- Enable VoLte First Then Mobile Data
- Now go to APN and create APN with Name " JIO " and APN "JIONET"
- Now it should work.
This is how it worked in my redmi note 3 (Snapdragon) MIUI Beta 6.9.9

is it stable? i am getting volte but device keeps losing it time to time..

Volte calling issue after 7.1.1 update

I am facing a strange issue just after 7.1.1 update, The 4g calling icon on the status bar suddenly disappears sometimes and does not came back , even if I toggle the airplane mode several times it does not come back. In that situation I am not able to make calls from jio, the only way to get back 4g calling is by restarting the device which is very annoying as I have to restart my device 2-3 times a day for this issue?
Is anyone facing similar problem?
Is there a permanent solution for this issue?

didn't face any Volte issues till date ! Using JIO sim too
what was your mode of updating to Nougat ? i mean OTA or manual.
Did you reset the phone ? ( Both hard reset and software reset)

I flashed the stock image via cmd

No VoLTE issues here too.
I had too flashed the fastboot file for my device using ADB. There was no such issue present for me. Can you please explain when and in which circumstances you are facing this issue? We may be able to help you further then

BAckup data ! go to backup and reset in settings and reset your phone. Then once it shuts down , enter recovery and wipe data + cache
Hope it helps

There's some problem with the sim or the SIM slot bro. Can you get it checked at the nearest authorised service centre?

Well I don't think here is any issue with the sim or the sim card slot. I tried with another jio sim and the issue was there. I even did a factory reset and still the issue persists. there was no such issue on 6.0.1.
It does not make sense taking the device to service center as its out of warranty and they will charge a bomb for it. The moto g5 plus had similar issues and was fixed by an ota update. The last option left for me is to reflash the firmware and if that even does not solve which I am sure wont work I am going to sell the device.

Does anyone get enhanced volte option if we put the jio sim on second slot

Unique volte and data bug in all custom roms in my device.

Hey guys,
Recently I flashed nitrogen is roms by soleintic,the ROM was working flawlessly without any issues...Today I went to service centre to get my device's speaker changed.After getting my device back volte was not working while previously it was working,So I thought changing swapping the sim slots would do the work I did the same and volte was working then but my data was not getting connected it was showing some random error in ipv6 and ipv4,then I again switched the sim slots and in slot 2 the data was working but volte was not working so I thought reflashing the ROM would fix the error.I reflashed the ROM again but the error was still there...So I decided to switch ROM..so I flashed PE ROM 5 mins ago but it's showing the same error pls help me I can't understand the real problem.

In short...Volte is working in slot 1 where as data is not working in it where as data is working in slot 2 but volte is not working there....The exact thing on phone info is
Ipv4:fail(2)
Ipv6:fail(2)
HTTP client test:Failed(IoException)

Flash miui rom and then flash any custom rom. I'm not sure where it'll fix the problem but chances are high
