Please can someone know if 3G and 4G works in both SIM slots ? SIM management "Switch" option for data source ? (SnapDragon)
Thank you for your response.
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?

global developer 6.4.9 beta. i already tested on several roms.
upps
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
I have a S5 klte duos and i have tested and both of my sim card slots can do 3G but when I use them both (one for data and one for calls/SMS) it forces one of the sims to 2G. Is there any way I can get dual sim standby? I want to get calls and texts and have data. But I don't care if my data is interrupted from a call or a text.
Any solution to this? I am currently using a jio sim and have to use the Jio 4G Voice app to make phone calls after flashing LineageOS. It is inconvenient to be honest.
Anything to do with the fact that I am using the sim in question in the second sim slot?
Already answered, use sim in slot 1
I have jio in sim2 and volte working good.
I have a strange issue with dual SIM.
I use a Telekom SIM in Slot 1 and a Vodafone SIM in slot 2.
Both Sims are correctly registered in their network and I can use data with either Sim card.
I settings I I did not preset any SIM for outgoing calls, so I can choose in the dialer which SIM I want to use for the call. However, no matter which SIM I use, always SIM 1 (Telekom) does the outgoing call.
if I deactivate SIM 1 and do a call, SIM 2 should automatically be used. But then I get an error "mobile network not available". Although data via the mobile network is working.
If I completely remove the Telekom SIM from the phone, everything works fine with the Vodafone SIM. So it is not a problem of the SIM card itself.
If I swap SIM cards and put Telekom in SIM2 and Vodafone in SIM1, also always the Telekom SIM is used. (SIM2 now).
I appreciate any help or ideas.
Same problem
I have the same problem and it is very strange why not people have noticed, I almost didn't find it in any reviews
I use 2 Sims as well be it 2 Swiss Providers but for me everything works as it should. I can choose to Use either Sim1 or Sim2 which works as it should. I can also set to use Data from either Sim1 or Sim 2 or even combined.
So it might not be that noone has noticed this problem - which could be provider specific - perhaps its just working fine for them, like it is for me

Hi Guys,
Just realized a quick fix for myself.
Settings-> Apps -> Apps -> Tap on Settings (3 Vertical Dots on right hand top corner) - > Show system Processes -> Type Search for "Phone"
Clear Cache and Data for:
1. Phone Services
2. Phone/Messaging Storage
Reboot. the calling function on both the sims should get functional.
Cheers!
