Can't use two sim at the same time in any custom rom (Airtel 4g + Jio) - Xiaomi Redmi Note 4 Questions & Answers

Hi All
I am was on RR(official) {also on bootlegger} and trying to use two sims (one Reliance JIO and other is Airtel 4G) but getting network coverage only in one sim whichever I set as default for data. If i set airtel as default data sim then only airtel sim will get signal and if JIO selected then only it will get network.
No service in other sim, even tried searching for network but getting an error "Error while searching for network", so not able to use dual sim on RR or any other custom rom.
I tried the same thing with MIUI and both the sims are working fine.
Does anybody has an idea how to fix that and use dual sim in custom roms.
Thanks in advance.

SIM error/No SIM

I have Moto E XT1022 obviously. I have recently started facing an issue on my phone. I have 2 SIMS. First one is Vodafone and second one is Aircel. Vodafone is in SIM slot 1 and Aircel in SIM slot 2. After some time of usage, I lose the data option for Vodafone in the settings. There is only option to enable data for Aircel. Also, in the messaging application, the SIM1 is greyed out. I still have full signals on SIM1 and I can make and receive calls from SIM1 as well. But when I hang up, the dialer screen shows "No SIM or SIM error" at the top.
This problem occurs in ALL ROMs including custom and stock ROMs. Once data option for SIM1 is gone, I can still use 3rd party apps to enable/disable data on SIM1 but still there is no option for it in the settings. This problem can only be fixed by rebooting the phone but the option again vanishes after few minutes of usage even on a clean ROM where I have no app installed. What might be the problem?
Both my SIMS are on roaming and I have enabled data roaming on both SIMS.
See if the problem persists when you interchange the sims.
i.e. Aircel as sim1 and Vodafone as sim2.

Thing is that this problem is there in stock motorola 5.1 ROM too. I didn't use to face this before on CM. I don't know when it started. By the way, are any of your SIMs on roaming? As far as I remember, this problem started after I moved out of New Delhi and now I'm on my holidays and both my SIMs are on roaming. This problem started after that only.

Means the data option vanishes right? Either this is a SIM problem..I mean the SIM card itself has that problem or this is related to roaming thing. Can you take the SIM on roaming out and test the phone for a few hours and check to see if this error occurs?
I also facing the same problem .. When ever i pick up incoming call it do not detect the sim on which call came .it just shows no sim card / sim error..
Sent from my XT1022 using XDA Free mobile app
I'm using moto g2. I'm also getting the same issue..."no sim or sim error"its really irritating .I'm missing my calls . hw can I fix it???? Plssss suggest the needful measures at the earliest.

note 3 pro 2nd sim 4g problem

i have a problem about my 2nd sim. i have two sim card and both are belong to the same network carrier. 4g indication is only shown on 1st sim card. when i turn the prefered data sim card to 2nd sim, 2nd sim always on 2g connection even lte is prefered. i swaped the sim cards and 2nd sim still shows 2g conncetion, so the problem is not about sim cards or carrier.i checked that when i put the cellular network to manual mode instead of automatic and data is selected sim 1, 4g networks appear in the search list. when the sim card 2 is selected as data and search for network, only 2g networks appear in the list.
sim 1 4G sim 2 2G OK
sim 1 2G sim 2 4G Not OK. both sims work on 2G (or sim 1 is 3G, i can not see any indication on top )
i checked the *#*#4636#*#* testing mode and both prefered network types are selected the same "td-scdma, gsm/wcdma and LTE"
when i bought the mobile phone, i had not got such a problem like this. i made imei repair operation and my phone works like this after imei repairing. i also test my imei numbers on both sims and still the same.

Remove both sims, turn it off, place jio sim and turn it on. Make sure LTE mode is on for the sim.
Go to mobile networks, and choose accesspoints, select loop or jionet if seen.
If list is empty, click menu, create, name it jionet in first to items, click save. and select it. see if it helps.
Mine was having trouble, so i flashed Krexus rom, it's connecting now.

Which model of Honor 5X are you using ?
Indian Model (KIW-L22) Supports Jio sim. Other country models might support Jio sim if it is configured for Band 3 (1800Mhz), Band 5 (850Mhz), Band 40 (2300Mhz).
Mine is L24, it supports Bands 3 n 5.. i got JIO signal too but No LTE data even after creating APNs with EMUI. Only after changing to CM/Krexus, data started working. Tried APN jionet and www none worked even after restarts.

You should contact JIO customer support if the issue persists.
I have KIW-L23 which supports only Band 3. Still I get LTE data after setting up the APN as jionet
dont worry, this happened to me too, just do this,,
remove sim card,
make sure you insert jio in sim 1
reboot
and this is important "SELECT DEFAULT SIM CARD FOR DATA" in settings
reboot,
you should be all set now,
For me, somehow Jionet apn did not work.. apn www worked fine.
Have few queries.
In Settings -> Dual SIM settings
Have you set the 4G/3G slot to the JIO SIM slot?
Have you set JIO SIM slot as default for mobile data?
I have jio sim.I used in my honor 5x phone since 1 year,it working fine.But 2 months back,the sim is not working. Now that I have put the sim in my honor 5x it shows signals,but internet is not working and also unable to make & receive calls.I tried the same sim in Samsung phone,it was again working fine. Can anybody tell me what should I do to make it work?

V30+ India Jio in Sim2 slot issue

I am facing issue with Jio network. If i choose mobile data from Jio sim it works fine (in both sim1 and sim2 slots). However if i choose Mobile data from other sim (vodafone in my case) Jio sim doesnt work. As soon as i switch data from Jio to Vodafone i get warning popup that Volte will stopped working and after that Jio network goes to Emergwncy calls only.
Anyone else facing this issue? Is there any way to work Jio sim just for calls and use mobile data from other sim? Please advise.

Because Jio is 4G-only network, it doesn't have 3G or 2G network to fallback unlike Airtel and Vodafone(in your case)which has 3G and 2G so it can fallback if you switch data to other sim.

Internet not working while on a call

I have just bought poco f1. Mostly i am happy with my decision. I use bsnl sim as my first sim and jio as my second with data assigned to jio. Volte is also enabled. I see that when i am on a call the internet is not working , 4G icon also vanishes. I am sure this has a simple fix, someone please suggest.

I'm pretty sure when you are on a call on a network, you can't use data on the same network unless you have volte enablef. I could be wrong. :angel:

When you're on call the 4G symbol disappears and you'll get only 3G. It's happening with me. Internet is working and speed is also good.
That is normal, had it on a lot of phones.

With volte services on u will get 4g data while on calls. If u r not on Volte the data network will change to 3g or 2g and data will keep on working .
But there's a catch , in dual sim mode only one sim data is active . So if u have Jio and BSNL sim and Jio has data
1. If BSNL call comes u won't be able to access data during data.
2. If Jio calling is used u will get 4g data during call also.
U can try putting Jio in 2nd sim slot and enable dual 4g and also enable use 2nd sim data if volte call.

I have enabled dual 4g and also enabled to use data on 2nd sim if volte call, but still i cannot access data while on call. I have airtel in slot one and jio in 2. Data is selected on 2nd mostly i use airtel for calling. Any new ideas?
Network connection should work even on calls, but limited to 2G or 3G. This is not normal on first sim card.
Enable this.
