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

In the SIM 1 the Network is JIO 4G and in the SIM 2 the network is Vodafone 4G. The country is INDIA
Same happens on lgv20 but it works fine on s7

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.

Is it possible to use jio sim on sim slot 2 ?
I'm using moto x play dual sim indian with latest marshmallow update.
I know both slots are 4g supported .
But When I inserted jio sim in sim 2 slot a pop up msg shows if u want to use LTE then insert jio sim on slot 1.
What to do ? Sim 1 is my primary number (Vodafone)
And in network mode selection phone is not showing VOLTE ,it's just showing 4g.
Need urgent help.
sim 1
i am using jio sim in sim slot 1 and it gives upto 45mbps
you can use jio sim in sim 2 but you need to select sim 1 to 2G only and sim 2 to 4G(recommended)...
note:YOU CANNOT USE SIM1 IN 3G OR 4G UNTIL YOU CHANGE SIM2 PREFERRED NETWORK TO 2G..

Why I'm getting this pop up ?
I put jio in sim 2 n I had this pop up too. After putting it in sim 1 I got new option in cellular network called "enhanced 4g LTE mode".maybe both slots support LTE but only slot 1 supports volte.
PS: (sorry for off topic) I just got my jio yesterday n the guy at digixpress mini said it'll take 15 days for activation. I'm getting 'no service' right now.is it okay? Or should I at least get signals?

It's normal it will show no signal or emergency call only. Activation time depends on your state and place. if the store has more sim activation pending then your request will be get delayed.
When your application has been updated to jio by the store then you will receive an sms.
After one of that your sim will show signal .
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?

That's expected because JIO is a 4G only Mobile service.
Any Dual SIM device can have High Speed Network on any 1 of the 2 SIM slots and the other one will always remain on 2G. So whenever you are enabling 4G on Idea's SIM Slot, JIO's SIM Slot is being changed to 2G only and JIO can't receive a Signal in 2G mode. I am not sure but I have heard that in few Cities in South India JIO has partnered with BSNL to use it's(BSNL) network on 2G mode but I don't see how it's gonna work or even if it's true or just a rumer.
So, if you want to use JIO you need to have 4G enabled in it's SIM slot and make another one 2G.
Hope I was able to make your confusion clear. Feel free to ask back if you have any more questions.

Hi Everybody,
I am stuck with my OP2 OOS 3.5.6.
So after i got the 3.5.6 i was not able to get VOLTE. So i found a resolution on the OP2 forum:
They advised to downgrade to 3.1.0 and then to upgrade to 3.5.6, did that and was able to get VOLTE, but another issue started, as in India Jio is a 4g service and I read somewhere that we will have to use it in SLOT 1 , so i did the same, and Vodafone in SLOT 2.
When i did that Jio works fine but there is no network for Vodafone.
After that i have tried the following:
*Selecting network manually.
*Changing the band.
*Reinstalling the OS.
*Resetting the network settings.
*Wiping out data and cache.
Nothing worked for me, can somebody suggest me something.

If you remove the Jio SIM and leave the Vodafone SIM in slot 2 does it connect to the network?
Does the Vodafone network support 2g?

You only answered one question!
Does the Vodafone network support 2g?
Does the Vodafone sim work in slot 1?
Does your SIM 2 have an IMEI in settings > about phone > status IMEI info?

Yes Vodafone does support 2g but when I select 2g and the Sim in the slot 2 it does not work.
Yes the Vodafone does work fine with 3g and 2g network in slot 1.
Yes the Sim 2 does show the imei number under settings.
You can select vodafone in slot 1 with 2g then put jio in slot 2 and select 4g as the 1+2 has dual LTE standby so jio should work fine on slot 2

Does really op2 has dual stand by, as I am not able to get volte and I have the Jio in slot 2.
Also I contacted op2 customer care and they mentioned that it will only support one 4g and other will be only 3g.
Does it work for you if yes can you please let me know what are the settings you have.

Dual sim standby works fine for me but I'm not a Jio user.
OnePlus support are wrong, If your data sim is 4g, the other drops to 2g not 3g.
Not sure what your issue is though as I've only heard of it affecting some (but not all) Jio users.

You both are right they did mention 2g,my mistake that I mentioned 4g.
Yes I got a few users who mentioned the same of not getting network in the second slot. I did got a hint from somebody that it might be an issue with the update and a fix is in the pipeline. But again its just a hint and not sure.
Thanks a lot for all the help.
I have two sims A and B connected to networks .sim A is selected for cellular data but when i change it to sim b , the network on sim b stops coming and until i change the cellular data to sim A and restart the phone Sim B wont connect to a network, error while searching for network is displayed while trying to search for network manually. Does anyone know is it a sim problem or with the mobile. I have even factory resetted the phone and changed the sim slots.
Is one of the SIMs Jio 4G? For it to work, you'll need to set it as the primary data SIM. As soon as you change the data SIM, it will deactivate itself from the network.
So, likely my G4 plus did the same while activating data on another network, JIO4G automatically turns off!

tried that did not work , one sim is airtel 4g and other is vodafone
That's a model and/or mobile operator dependent problem. I have XT1642 in Germany and never had that problem with both sim slots.
What model did you have and in which country?
it's only due to jio sim in india
