Its possible that you can keep two 3G SimCards in both slots.
And even use 3G from both sims (ONE AT A TIME ONLY), but you have to change in the MobileNetwork Setting that currently which SIM you want to be worked as 3G and which one as 2G.
Only one 3G sim can use 3G network( AT A TIME)
:good:
I Have samsung Galaxy Grand 2

i think it is not problem with phone .

After making some changes in service menu, i am unable to use dual sim functionality. I can use only one sim slot at a time. The other one shows no network available. Regardless of which sim slot i use. In service menu sim slot 1 can be set to any preferred network but sim slot 2 is stuck in gsm only mode. Manually searched for network but no network available. Flashed latest oos 3.1.0,still the same issue. Can anyone help me with this.
Thanks in advance
Just restore whatever change you did in service menu and you should be back, you should not have played around in there from the beginning ?

Service menu doesn't have an option to reset to default and i don't remember exactly what changes i made. Yea i shouldn't have touched the service menu. If there's any thing else that can be done. Thanks for the quick reply
I think you changed radios to be only 3g/4g and your carriers uses the same band

I'm not sure what changes I've made but yes both providers use band 40 2300 mhz for lte. I've tried changing one of the sim to use only 2g so that both sims are on different band but still same issue.
If you are in an area where carrier uses exclusively LTE that's the problem, opt radio is dual standby it alternate between two signals in any of the combinations 2g-3g/lte but not 3g-3g or lte-lte

My phone was working fine few days ago. I messed up something in service menu, after that the problem started. I have set one of the sim to use 2g manually, still i can't find any signal and both carriers use 3 different bands.
Have you found any solution i am facing exact same issue after changing network band. please help

No wifi, no simcards detected...
Can you explain how it makes it work?
Here is a good read about such dual-sim issues (esp. posts #3,4):
https://forums.oneplus.net/threads/dua-sim-detection-problem-only-one-sim-being-detected.430976/
I'm a noob with this stuff, I read that forum and I'm still unclear... Is there a work around or am I screwed? Is it the phone/Software or my sim cards?
Here is the solution
In order to solve the problem go to service menu by dialing *#*#4636#*#* then turn off radio then select radio band 32 when it says successful, restart your phone and the problem will be solved
Say thanks at fb.com/suri131
You can contact for any other issue too
Finally solved the issue
I too faced similar issue and solved it now. I'll share my observations here.
I had 2 4g Sims Airtel and Jio. Jio for data. Both the sim's were working fine , once i went into roaming suddenly after that airtel stopped latching to network. Whatever sim slot i put my airtel sim it's not getting network if in the other slot Jio is there. I tried to use my airtel sim in other phones and it's working fine. I tried putting only airtel sim it's working fine in my OP2. I thought this may be imei problem and checked imei , my OP2 has both imei in it.
So now the fix part , for me 4g sim was working fine so tried fixing the other one in sim slot 1 i.e.. airtel.
*Install and open Shortcut Master(Lite).
*Menu->Search->Type "Engineering" -> Select "EngineerMode" from Search result (package name:com.android.engineeringmode.EngineeringMode) ->Launch.
*Click Network Set
*Click Sim Card Select -> sim 1
*Click Rat mode ->Select GSM only
*Click band mode->Select PGSM 900/1800
Now turn on Airplane mode on /off wait for a minute you should see both network.
Summary: In OP2 one slot will be 4g / other will be GSM 2g... So whichever sim is working for you don't change settings for that sim , play with the other sim for which no network is coming.

Hey man. Installed a custom based on android 12 and i'm not sure what happened but only one sim card was working. Used msm tool to go back to oos 12 and now only one sim card shows.
Was going to try your method but the "engineeringmode" does not show up in search.
Any suggestions?
I have an OP2 OOS Version 3.5.6. My two sim slots are also filled up with two sims. So the Problem here is Only one of the Sim works at a time. Suppose if i keep the PREFERED SIM FOR MOBILE DATA as SIM 1 , the network of SIM 2 goes off and only SIM 1 is active.Vice versa . Please help me and as far as i remember i did not configure any unneccesary things. I am just noobin these stuff.TIA

You can't use two 4G SIMs at the same time.
The SIM not set as the primary (data) SIM can only connect to a 2G network.
It's always been like this on the OP2

I mean't to say that Vodafone is 4G enabled Sim. It is not mandatory that it should work only on 4G.
Whereas JIO is a Network Where 4G is Mandatory. BTW it was working fine for the past three months without any issue.
And I even tried Having Airtel as the 1st Sim and Vodafone as the 2nd sim (Vice Versa) it doesn't work..
I thought if i Factory Reset the phone the problem would be gone, but it didn't ! Probably i have to go to a Service Centre

If your JIO SIM is the primary SIM and Vodafone have a 2G network in your location, the second SIM should be able to connect too.
If it doesn't, something isn't right.
