Problem with Network - Lenovo ZUK Z2 (Plus) Questions & Answers

While Jio is activated, volte works absolutly fine, but calls from Airtel doesnt connect.
While I Deactivate Jio, calls are connected through Airtel.

Network problem on ONE PLUS 3

I just brought a One plus 3 last week.
I m using jio in sim slot 1 and bsnl in sim slot 2.
If I select cellular data on the Jio sim, both sims have network. But if I select cellular data on Bsnl sim, jio does not get network. I m using on oxygen OS 3.2.6.
It is hardware or software problem?

thats probably because jio is a 4g only network and oneplus 3 doesn't support both sims running 4g at the same time.

That doesn't matter, you can only set 4g network on the sim that has an active data connection. Suppose you have idea and Airtel and both have 4g, which ever sim is your data sim will be able to have 4g access.

VOLTE(SIM-1) & 4G Data(SIM-2) Not Possible?!

Hey guys,
Just yesterday I came to know of this annoying problem with our device. For context, I use Jio as SIM-1 and Airtel as SIM-2. So what I was trying to achieve is to use 4G data from SIM-2 while SIM-1 was 4G & VOLTE enabled. But the irritating thing is this configuration as far as I tried not possible. Even searched all over XDA and ZUK forums for our phone and still no solution. While SIM-1 is the Data SIM, SIM-2 can still be 4G (but what's the frickin purpose). But When SIM-2 is the Data SIM, SIM-1 can't be 4G or have VOLTE flag. Then I thought if this is problem might be over if I interchange the SIMs in the slots. Now SIM-1 is Airtel and SIM-2 is Jio. Now also if I set SIM-1 to be Data SIM, Jio doesn't receive any frickin signal or VOLTE Flag. If Someone can please help me solve this problem, it would be very much helpful. Or I would like to know whether this problem is with a particular ROM only. I Run RR 5.8.4 with latest basebands and Darkmoon Kernel. Please Someone Help me with this.
Bro it's the same for any phone none have dual 4g standby and as you switch data sims the Airtel switches to 4g while jio gets downgraded to 3g where it can't work properly

But dude when I have Jio as my Data sim, airtel is receiving 4G. I double checked that.

I can confirm that.
And also I've checked three other phones (Oneplus 2, Mi Max, Le 2) where the phones donot completely lose signal (though happens rarely but a reboot rectified it). I think this is more of a ROM based feature than a hardware incapability. If anyone can confirm that this particular configuration of SIMs work on any other phone(s), we could probably port that feature atleast as a Magisk Module.
This is not a phone or ROM problem...its just that jio doesnt want users to use free voice while they are using different carrier for data!
Mi a1 getting dual volte feature via new software updates, so can't we?
Dual volte is successfully implemented on mi a1 with software and ours is SD 820 I think we can also enable it

Most 4g have backward support 3g.. so even though the phone is latched on to 4g it is actually connected to 3g bands.. true volte is only jio.. if volte switch is off and you are still making calls then it's backwards 3g that is gsm network

For me jio is volte first sim and Vodafone LTE on second sim.
can someone confirm me if airtel VoLTE is supported in their z2 plus even on single sim? I asked customer support of airtel and they said that our phone does not support VoLTE feature of airtel.

data on 2nd sim on any custom ROM

I am facing data switching issue from my 1st sim(Jio) to 2nd sim (airtel) on any custom rom. previously i was in MIUI 8.7.26 and then after wiping system data and dalvik i flashed RR and AoSp. But in both the rom I'm facing this issue. Data on jio working fine but when switching it remains on jio. If I toggle airplane mode then for a second LTE data sign comes into the airtel then vanishes. No data on jio or airtel. Again if change data to jio data works and on changing to airtel it remains on jio.
Apn settings are ok for both the Sims. Data roaming and enhances 4g on for both the Sims.
I know it is not at all rom related issue. But I'm puzzled why this is happening? Can any one guide me?
exactly this. finally, someone having a similar problem. i was going bonkers thinking it was only me. i even made a video of it - https://www.youtube.com/watch?v=sgyNm1Czrks.
i am still looking into this. it happened on RR and LOS. I'll let you know if i find something.

Do try other custom roms also. Like aex and pixel experience also. I telegram somes are saying AEX and moner don't have this problem.
I saw your video. After toggling airplane mode your 2nd sim data (jio) works. But for me 2nd sim Airtel data comes for a second and vanishes.
There is a problem in the source of the LOS and AOSP may be.
I'm going to try one by one and let you know. You also try other Roms and let us know.

SURE. i am not so sure about this problem being in LOS itself. I say this because i was using non-official LOS since april and data switching was seamless. idk but this started only after i flashed official build. i'll try other roms, but as of now, this happens on RR & LOS. my data comes for a second and vanishes as well; i have to put it on airplane mode multiple times for it to work.
Hi ,i am on AeX to Switch ist no Problem ,but if i Take a call on Sim 1 - Sim 2 stops working Mobile Data until i end the call in Sim 1

I think it's same in miui too. If data is connected in sim 2 and you received or do call from sim 1 sim 2 data is disable for that moment. That's not a problem. It's like that.
Thank You , i dont know, miui runs short time by my Side .
I thougt it runs ?
I was having a similar issue on RR and AEX. On AEX I turned off Enhanced 4G LTE mode and then selected correct APN. The internet works on the second sim now. Hope this helps you.
Hey! I solved this issue. I Changed the apn name (jio internet to JioNet) and turned off enhanced lte. Data is switching seamlessly now.
Let me know of it works for you. Find the correct apn settings for your ISP.
well, looks like i jumped the gun here. disabling enhanced volte makes data switching instant, but i cant make/answer calls now. OP, if you find something, you let me know.

Yes turn on your 2nd sim data after turn off enhance 4G LTE Mode because custom rom support Dual 4G VoLTE on same time, Not supported 1st 4G VoLTE and 2nd 4G Only try it

None of this happened in nonofficial Los that i had. Clearly, this is a bug in stable version.

My Airtel and Jio both are volte enabled sim. In miui both works fine with dual volte.
Custom ROM has bug in it. My previous phone was le max2. I faced the more or like same issue in custom ROM of it also too. If u switch data from 2nd sim to 1st sim data would not turn on. To get it working either you have to disable completely volte. Or u need to restart your phone. Tooling airplane mode will not do the work.
But for note 5 pro this trick is also not working for me. I feel that the source of most custom ROMs of note 5 pro has this type of bug that's why it's present in most or every ROM out there.
Untill and unless they correct it from source it's difficult to get the desire result.
I had a similar problem, I had 2 Sims(for calls and data) the data sim only activates once, I had to switch to airplane mode and then turn it back on. The issue existed when it was the only sim on the phone too. I tried the sim on a different phone, and it worked perfectly.
So the fix was in the APN, the APN protocol should be 'IPv4' as the default was IPv4/IPv6 (same goes to APN roaming protocol), once I adjusted them, data works fine now.
Using MIUI 9.5.19

Strange I never faced anynissue regarding data switch in miui ROM. Even the data switch in dual volte works fine for me.
Anyways thanks for the suggestion in the changes in APN protocol.

Voice Call issue in custom rom

I'm currently using Pixel Experience ROM (Android 9) and have tried Lineage OS 16 and bootleggers ROMs.
The issue that I'm facing is that, the SIM card is unable to send or receive voice calls (specifically Airtel and Idea), but Jio is having no issues. Funny thing is mobile data works fine for all the above mentioned carriers. This situation is for the SIM slot 1.
Even though SIM 2 slot only supports 3G/2G, Idea and Airtel 4G with voice call services works just fine.
Can someone suggest or share their own experiences.
Thanks!!!

Havoc Os call ended issue

Im using Jio simcard LTE
but after install Havoc OS on my rooted device Im not able to call anyone, or receive calls. But Sim mobile internet is working fine.
My phone use VoLTE for calling, but I cant seem to find this option on Havoc os using Android 12 on onplus3t

Removing SIM card slot and changing mode again setting back to LTE enabled 4G calling feature. FIXED
