Dual LTE? - Xiaomi Redmi Note 3 Questions & Answers

I have one Jio Sim and one Idea sim. If I select cellular data on the Jio sim, both sims have network. However if I select cellular data on Idea sim, jio does not get network. Is this a known problem? I am using the CM13 Snapshot with CM13 firmware. Any help will be appreciated!
Thanks

Use Jio Sim in SIM 1 slot, i recommend you to flash modem files from MIUI 8(MM), The radio firmware which comes in Firmware.zip is buggy doesnt works in many devices such as mine. So i have to flash MIUI modems everytime when i flash CM and after that it works like charm.

Hi,
Can you please post that miui modem? I am on CM13 19sep Nightly and have flashed cm13 firmware before flashing Cm.. So i can still go to twrp recovery and flash that?
I am having Jio in Sim 1 and Airtel in Sim 2, Jio works fine but Airtel cant connect to network many times.. Network operator is shown in the results but I get error "Cannot connect to network right now, try again later" ... I have to restart to get airtel working (which stops after a while). Apn settings are all default.
Please help

Just download beta rom form MIUI, and extract NON-HLOS.bin file, and flash it in fastboot mode. dont restart the device, just switch airplane mode on and off, your network will be back.

This phone supports LTE + LTE standby. I think it means only one sim can use LTE at a time. Correct me if I am wrong.

his problem is when he turns On the cellular data on 2nd Sim, the network goes away completely on 1st one. if he is not using hardware mod 2sim+sd card, then its modem firmware not behaving.

U cannot use LTE+LTE, Jio being a All time LTE Network as soon u choose data on any sim be it on 1 or 2 the data shifts to LTE for the sim selected for data changing the band for network on the other simcard.
@Rohit DK donnot flash any modem it will not work. Also u might get problem with sim cards not detecting.

ohh.. i just forgot that JIO is all time LTE network, but flashing the modem files from stock rom will not messed up in anyway. @Rohit DK yes he is right, i literaly forgot that JIo is all based on IP network, so if you have cellular data turned off on JIO, Its still works on IP.. so yes you cannot use jio sim with other sim data on.

My problem is little different
I am getting Jio 4G in Sim 1 and Airtel in Sim 2
Sim 1 is set to LTE
Sim 2 is set at 2G
I get no network in Sim 2, when I search for network I can see airtel but I am not able to connect to it

let me simplify the language for you to understand maybe it might seems stupid for others, but i will try my best , JIO is all Data network, which means when you are not using its internet. it is connected to the internet, because it works on internet only, all calls, sms, everything works on via data connection only.. if you see 1 bar in network strength, it is connected via Data only, This is what LTE is. right now phones are not capable of connecting data on multiple sims at a time. so by this logic.. Your jio sim is connected to internet by Default(doesnt matter cellular data on or off, it is connected to it in both cases.) so when you manually trigger the cellular data on 2nd sim, JIo sim goes offline, because your phone is configured to connect data only on one SIM. huh..

did you try to change the modem? or you can check this with other rom whether it is working there or not.

you could try checking your apn settings, detection of apn are different on different roms.
or try forcing the network to use WCDMA mode (go to phone, then dial *#*#4636#*#*), go inside the first menu there and force it to use WCDMA (incase the rom toggles are misbehaving)

[need help] razr xt910 NO service But phone is reading sim card & its contacts

Guys I have a strange problem my razr wont connect to any of the data 2g or 3g only on custom roms like 4.4 Kitkat,Carbon rom etc . I flashed them on slot 1,2 even on stock slot but no luck.. I tried to change Baseband But It always failed So guys help me.....
Edit 11.12.2013:::
I fixed the problem partially..
I fixed the network mess It was bad radio which did this all I flashed ICS radio and now network works fine in all roms (Stock and Custom) BuT bo mobile data on any of them
Edit::::
Now Phone says NO SERVICE on both stock And custom rom but reads sim card contacts & SMS's...
I tried reflashing stock rom But no success. Help me guys...
2g/3g for many of the newer roms has been a problem with both the XT910 and XT912. I know with cyanogenmod 10.2 I'm still not able to connect to 2g/3g although LTE does work. With the newest release of cyanogenmod 11 though I do get 3g and LTE, although some people have been reporting they are not. Seems it's headed in the right direction. Give the latest CM11 build a shot and see if it works for you.

kk but still i have no luck getting 3g on newer versions too.
Is there any APN that saved in your network setting? If it doesn't, set it and save it by hand.

yup apn's are saved as usual

Can you make a call? Did you have paid the SIM card cost?
Sorry for my bad English
Yup my SIM is in contract and working on other phones I can make and receive calls but not on razr I get NO SERVICE message
Open the phone (or dialer, whatever you would like to call it) and Dial *#*#4636#*#* and go to Phone Information and tell us what the preferred network is.

Also:
What ROM did you get LTE Only on?
I learned that sometimes ROMs can mess up NV's. The only way of fixing this is to wipe everything and start fresh. And when you are flashing you cannot downgrade, it will fail every time. You may already know what I am telling you but just in case.
And what carrier are you with?

Hi. I have XT910 for more than two years. After brought the phone from Australia to Hong Kong (use Hong Kong SIM card) and back to Australia (replace SIM card with Aus one), I have the same problem as you. Phone can make voice call, but no mobile data connection (3G, 2G).
Want to know if your problem is fixed or not?

No 3g/2g signal, only LTE available, cannot make calls

Hi!
My phone is Redmi Note 3 SD, Kate version.
I've been using cm14 for a few months and then decided to flash nitrogen os. After flashing I can't call or receive calls from anybody, since my phone can only connect to LTE, but not 2g or 3g, and my network operator doesn't support VoLTE. I can still use data connection on LTE and send/receive text messages. My phone also connects to my Wifi network. When I select 2g only, 3g only or 2g/3g in settings I get no signal at all. My sim card and carrier (while connected to LTE only) are being detected, I have the correct IMEI. I've tried flashing MIUI through fastboot, flashing CM13, CM14 and flashing different kate firmwares on every rom. Does anybody know what to do?
I solved the issue by installing Network Guru and selected WCDMA in RAT locking menu. Then i selected clear forcings and the problem was gone.

I have the same exact problem, but on a Kenzo.. I don't have 2g/3g in Nitrogen OS, Xenon HD or Lineage os... but I have them on any miui ROM (official global dev/stable and xiaomi.eu)
But the strange thing is that I've been using Xenon HD and the Nitrogen OS for months without any problem... Before I try your solution, can you confirm your solution applies to the same problem?
TIA,
Gustavo Melo
I didn't have 2g or 3g on MIUI roms too. I recommend you to try it, you've got nothing to lose
You need root though.

Well... I don't know what to say... I tried the app still on miui (xiaomi.eu), and did what you described (even if the problem didin't exist on MIUI)... Then installed Nitrogen OS and... I have 2g/3g!... the only difference on this install is that I activated the phone without the SIM...
One of the two: or the Network guru app I used on miui persisted even after installing Nitorigen, or activating without SIM did the trick...
Thank you either way!
Eject your simcard
*#*#4636#*#*
And choose LTE,wcdma,gsm auto

No network (jio)

Why doesn't my jio sim get detected? It was working well on GSI ROM until I decided to switch to different ROM. I have tried all ROMs. All Pie ROMs. None of them detect jio network. Other networks get detected. Now I switched back to GSI via nandroid backup and I see it also doesn't detect jio network anymore. Kindly help. I tried clearing cache, system,data and installing 8.1 ROM and the issue is still there.

SIM detection problem after flashing PIE ROM

I have 3GB RN3 pro. I have installed official TWRP 3.3.1. I have tried to flash most of the pie roms available for kenzo but I face the same problem.
First I flash the latest available firmware 'fw_kenzo_miui_HMNote3ProGlobal_V10.2.1.0.MHOMIXM_36c0f5ded3_6.0.zip', then ROM zip , after that I flash opengapps pico for arm64 android 9. After the first boot, I setup my device, both the sims get detected, 1st sim on 2g & 2nd on LTE. But the problem starts when I restart it again , after second boot, only 1st sim gets detected, 2nd sim shows 'Emergency call only' status. Resetting network settings, subsequent reboots do not help. Due to this issue , I am unable to use any PIE ROM.

R u using jio volte sim ?
Use volte sim for sim1
And non-volte sim in sim2.
Keep sim1 as default for data and calls.
And keep sim2 only for calls.
