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.
What is the rom version you are having now?

I have exactly the same problem! I had bought the phone from a chinese vendor and I hade 3G only in SIM1 and 4G in SIM2 . I used a guide and flashed a global qcn and restored the IMEI cause it was lost and after that I face the exact same problems as Salagil
Hello all,
Is anybody have solution to use slot one Volte network for calls and Other slot for data.
Hi, I have put GSM sim to the second slot for calls and massage`s, and R-sim for CDMA data in first slot. It works good
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.
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.

Have you find a solution in the meanwhile?
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.
