Second sim signal problem. - Xiaomi Redmi Note 3 Questions & Answers

I have this problem in my second sim. The signal goes to zero from time to time and when this happen the phone stutter. I encounter this in all custom rom (CM-based, AOSP-based, and CAF-based). But it doesn't happen in MIUI.
I'm sure this nothing to do with kernel, firmware or my sim card. I have tried different kernel, firmware still got the problem. When I just use one sim, the problem still happen but not often.
Anyone can confirm this too?
FYI I have kate device with unofficial unlock. I start to wonder if this have something to do with my unofficial unlock.

How to install OxygenOS or better

Hi guys!
I have seen a thread with more or less the same problem. In most of european countries the white version of OPX comes with H2OS and its the e1001 variant.
The main problem is that the H2OS is laggy in games,very laggy. I have bought three OPXs in Romania and all of them have the same problem. How do I upgrade the firmware/software without root or TWRP? Is it possible? Because the guys that provide the warranty for this phone may void it if something bad happens.
I am running H2Os v1.2.0. It s very snappy with zero lagg but when gaming starts it is very rubbish. Help me here please. What am I supposed to do?
Thanks in advance for the kindly replies! I know that XDA is a bigger community than any other.

You can download the OxygenOS zip and flash it with stock recovery. I would suggest unlock the bootloader, install twrp and take H2OS nandroid there on flash O2OS u can test it for a couple of days and then decide for your liking between the 2 ROMs

I havent really used 2 sims in my oneplus x (germany) with oxygen os but in the android settings it shows all the stuff for dual sim usage. You can deactivate a sim and also set the preferred sim for data usage, calls amd sms.

....
Go to the stock dialler. Select the options from top right (3 dots after the voice search assistant). Select settings>Call Settings>Phone Account Settings>Make calls with. Here you can select 3 options. If you select ask first you'll be prompted everytime you make a call to select from which sim you want to make the call or select either of the sims directly.
But it does not work anymore in OxygenOS 2.1.2, 2.1.3, or 2.1.3-x . Maybe in future OTAs ...

Network Problem on 4G when using RJIO SIM in India

Hi,
I am experiencing network problem if i use any firmware based on CM. The issue is I get less network and something phone doesnt show any network at all. If I use H2OS or OOS I get proper signals with good speed. I have two ONYX and both have same problems.
I feel the issue could be disabling of a particular band which is used by RJIO in India. Do any body also have this issue? Please post your answers with suitable resolutions if any.
Same here.
If I'm right, you can use Jio Sims only on Lyf handsets, no ?

Well then you have to stick with oos I guess
Try restoring OOS EFS on the ROM you use. If you don't have OOS EFS Backup, Take Nandroid backup of your current Rom to your memory card. Then clean flash OxygenOS and take its EFS backup. Now restore your Rom and then restore Oxygen's EFS over it.
Also, can you reply to my PM? I need your help too.

You cannot buddy. Jio requires VoLTE (voiceover lte) or as they are calling it "True 4G", our phone just supports LTE, so there is no issue with your software, It's the hardware that is incompatible.

Hi, No its not like that. When we talk about LTE, we mean data so any phone in the world supporting the LTE will be able to use the data from the network if phone uses the same band. Now when we talk about VOLTE, its hardware specific and your phone should be able to make VOICE calls using LTE. Its generally a hardware which make enable your phone to send SIP messages using the builtin dialler and then DSP's for the HD voice. But again if your dont have VOLTE supported on your phone you can download dialer application from the vendor ( If they have) and use them to make voice call. The quality may not be as good as builtin hardware but it should be manageable.

X829 unable to make call/receive call when choose "GSM/WCDMA/LTE"

Hi Everyone.
Good Afternoon.
I facing a problem. Below is my problem description.
Background
Model :X829
Rom: Resurrection Remix (RR-N-v5.8.3-20170731-x2-Official)
Location : Malaysia
Telco : Maxis
VOLTE : Telco not supported
Problem statement
Unable to call when choose "GSM/WCDMA/LTE" at preferred network type in simcard settings. I choose this settings "GSM/WCDMA/LTE", i will get LTE signal connected and can surf internet for less than 5 mins.
When I make call on LTE signal, the signal switch to "H", but the call is not success, it terminated the call after around 10seconds. After it terminated the call, it switch back to LTE signal.
If i choose "GSM Only" at preferred network type in simcard settings, I get "E" signal , and no problem in making or receiving call and surf internet. But the surfing speed is very slow since is only 2G.
If I choose "WCDMA Only' at preferred network type in simcard settings, I got no internet signal (none of E,H or LTE connected), it just go to emergency call only
I tried flashed to many kind of rom like, Lineage , Pure Nexus, Stock EUI and etc, the problem still the same.
I did used QualcommTool.exe to change the frequency band for CDMA/GSM/WCDMA/LTE according to my telco provided frequency.
I did tried select all or select exactly same with my telco frequency , the problem still the same.
I did use *#*#4636#*#* to change the preferred network. I do not sure is this relate with settings at preferred network type in simcard settings. But changing this have nothing effect.

Well, actually 19s is the last version of indian ROM. I suggest instal 15s and update from it to the latest one. You can find the rom here.
https://forum.xda-developers.com/le-max-2/how-to/le-max-2-official-stock-firmware-links-t3433761
Yeah, VoLTE doesn't work with LeEco but this last version is highly optimised and all errors reported regarding 4G LTE are been fixed.

When you change rom, you need to wipe everything. Then flash the rom. Patience is much more needed. It took more time to load when you flash a rom

Hi,
I put the simcard to another le max 2 phone. Everything is fine. Can call, can online.
Thanks
Hi all,
Morning.
I found root cause for my problem.
My phone problem is unable to connect to 3g signal. Due to it unable connect to 3g signal, that's why when I on LTE, I unable to make call and receive call due to calling will switch from LTE to 3g. After it switched to 3g, it keep on connecting but failed.
Please refer to image below. The state keep on connecting and disconnected at B1 IMT 2100 band.
I did tried to put my simcard to another le max 2, it works fine. So I believe is not telco problem.
Below is my telco link

Any ideas?

I cannot register network

Hi
I recently received n x820 with rom 19S installed. The reception bars were shown but nothing I did or EE my service provider would get it registered. My sim works in another phone.
I installed twrp 3.1.1-0-x2 and oreo pixel experience is working well apart from no service re mobile. Fingerprint works fine.
I looked at the radio its set to usa or automatic. Preferred network type is TD-SCDMA/WCDMA.
I am in UK does this mean my phone wont get a mobile signal in UK?

Heyyo, have you tried flashing upgraded modem firmware?
Just flash via TWRP and reboot
Either try Developer 466D

Or Chinese 26s 05.09
https://yadi.sk/d/woKdrlRrv8yhr/Китай

Hi The_Mard, I tried both but without altering the test settings on radio switcher.
Still no service. The mobile network icon has no bars showing, and on 26S modem it defaults to WCDMA only.
I tried them both with very little time between change. Should I turn on/off phone?
Heyyo, hmm do you know by chance if your phone came with Indian or Chinese 5.8.019s?
One of the only other things I can really recommend is try flashing EUI ROM 5.9.028s the last stable release just to see if flashing it plus all the firmware it comes with will solve the issue for you.
Here's the official link for it

Thanks for the suggestion. I bought from a Chinese seller and the ROM had been customized for the English market, geekbuying had a version of this on it LE_X2_X820-OS-OP-FGXOSOP5801910121S-5.8.019S.zip.
I'll try the 28S but as I am rooted with twrp can I install it or only with ADB?

Mine installed via TWRP it just got grumpy during TWRP install saying there's extra files it didn't know what to do with but it still worked
Twrp installed it and aroma arm64 6.0 provided a nice pixel launcher.
The network search shows 4 bars on the phone which is an improvement. But it can't connect though the region is Other, time and date are London and GMT.
I feel this may be a hardware issue as the network has never registered.

Kenzo itself is dual sim and i am also using both sim cards also. I was wondering whether there could be any updated or modified modem for India.
I knew none of the unoffical Rom files will have modem. But googled and didnt find any update or custom rom. Wondering few sites like 4pda were recommending epic modem 7.11.6 Noughat for better coverage. But i didnt find any other links. So with curiosity i put my question here.

Put the sim in slot1 which u use for data. Sim2 slot is only for calls. Its issue in kenzo. Miui global works fine may be. But custom rom with issues.
If u use sim2 slot for data then u will come across network drop.
