Hi guys, i noticed this big issue using my phone.
If i enable 3g for sim1, sim2 is completely offline (it can't recive or do calls).
If 3g is disabled, both sims work well simultaneously.
As you can undertand in daily use outdoor is a big problem.
Test done in MIUI v37, v45 and v47, Carbon rom, Mooke and CM11.
Have you the same problem? Do you know how to fix it?
Thanks
I have the same problem. It's not your phone or the ROM you are using. It's just that the sims are not full active. The best solutions are:
- Don't use two sims ( I gave up. I have two phones now. Too many missed calls)
- Redirect the calls from a sim to the other(and viceversa)
Hi, I don't know why, but after I wrote this acting on sim settings I found a correct way to receive calls with sim2. Probably just luck in these hours but for now it works! I'll attach a screenshot to show you exactly what I did. Let me know if work also for you, in order to help some other users... [emoji3]

Hello! I don't know if I'm the only one, but I have this problem. I use the first sim slot for data and the second sim form voice and messaging. From time to time (and I never know when it's happening), the data on the first sim stops working. It is on, but on the status bar I can't see anymore the "H" or "3g" icon, and the internet is not working. The single way to solve this is by rebooting or turning on and off the airplane mode. Also, the second sim goes on some sort if stand-by. That means when people call me, I don't get the call, and when I try to call, I can't (the fixes are the same as for the first sim). Also, I never know when this is happening. I know have CM11 (updated) but I've encountered this problem with all the ROMs. Even the official one. Is it a hardware or software problem? Does anybody have any idea how to fix this? Thank you in advance!

have you test using 1 sim only on 1st sim slot for data and voice call?
AFAIK 2nd sim slot only can use 2G, and 1st sim slot can use 3g or 3G

Yes, I tried using only 1 sim and there is no problem. The problem appears only when I'm using both sims. But what is good for a dual sim phone if I can't use it, right? That's one of the reasons I bought the phone.

No, the sims are not for the same provider. (One is Orange and the other is Digi). And as I said. Using any of them single doesn't cause any problem. But when I put them together in my phone, the problems start.
I thought I was the only one. This problem does exist on this phone! I experience it a lot on first sim. Net keeps going out a lot and I have to turn net off and on several times before it comes back. Using airtel and vodafone. I also think the phone goes out of coverage a lot cause after i started using this phone, people suddenly started sayign that am out of coverage
Same problem

And there I was, thinking that it was a hardware problem.. I started noticing this recently when all my friends started saying that i am 'Not reachable' ( On Airtel network :silly: )
Data issue is something we can keep aside, but not able to receive calls and place calls .. ??? Now that's a bummer..!! What's funny is that this issue occurs only if you use two SIMs.. On Single sim it works good. I have been trying to get a work around for this (Other than rebooting and airplane mode) .. Anybody has any input on this ??
*Sorry, I posted on the wrong thread..
I don't have an issue making/receiving calls on both sims on the old miui or custom roms. But I don't keep the data modem on all the time.

Are you sure that your network coverage includes at least 2 available bands in the 2g-3g range?

I'm not sure about this, if you use cm11 maybe you can enable "Tuneaway" and set the "Priority Subscription" to sim1 or sim2 in the sim card settings..

Hi,
I'm facing a strange issue with my 9 month old Redmi 1S since last 2 days. Whenever I dial a number the call immediately disconnects and all I see is "Call Ended Not Connected".
I'm using 2 Sims, Airtel in slot 1 & Bsnl CellOne in slot 2. First I thought that maybe its a Network Issue but when I tried both the sims in a different handset, I was able to make calls. I tried an Aircel sim in 1S as well but same problem.
And yes I'm able to receive calls, 3G is working fine but can't make Voice Calls. The OS version was JH45 and I didn't update as I was waiting for Kitkat/Lollipop ROM. But last night I updated my phone to latest JH 56.0 assuming that it will solve the issue but the problem still persists.
Also, someone advised me to clear system cache from recovery which I did but still its the same.
Hoping to find some solution from the members here.
Regards.
So, nobody is gonna help me here?
I am able to make calls only if I prefix number with *31#
Why?
Hello there,
Im getting trouble to get the dual sim working properly.
First of all my setup : OOS 3.2.7, rooted, some xposed modules, nothing fancy. Stock kernel
SIM1: Data SIM, o2 germany
SIM2: Just used to receive some texts, all APNs deleted, Carrier : Orange/Sosh France
In normal usage SIM1 is deactivated. In this case everything works flawlessly.
As soon as I activate SIM2 i run into trouble. I loose data on SIM1 almost instantly and the only way to recover it is usually a reboot.
When i loose data the "LTE"/"H"/"3g"/whatever icon disappears, data is still on in the settings.
I noticed that at least once both sims were connected on UMTS when it occured.
Any clue to keep my data connection working when both sim cards are active?
Thank you in advance
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.

Hey thanks buddy ? but i can't use volte anymore ?
Hello, I bought an S7A on eBay. I unlocked it with the GSM unlock code provided. Everything works fine, except ... I can't make or receive calls. When I make a call, no ringing tone, and it hangs up 20 seconds later. When someone calls me, the same, then they come across my answering machine.
I'm on the latest version of Oero available, no root or whatever. From what I saw (on GSMArena), the phone uses compatible frequencies in France.
I am at carrier Bouygues Teelcom.
You have any ideas ? Thank you !
PS: I translate from French, please be indulgent!
Same problem, this phone does not work in China
Since then I have understood the real problem: the phone cannot switch from the 4G network to the 2G network for calls on its own.
I don't know how I did it, but now I can make calls without any problem, but switching to 2G is very long (15 s).
I specify that it is impossible to use VoLTE to circumvent this problem.
For receiving calls, the phone does not switch to 2G and the incoming call still fails.
But I can force the 2G network (With the Samsung Band Selection app). And there, incoming calls work, but we only have 2G to surf.
When connected to WIFI, the phone automatically forces the mobile network to 2G, so incoming calls work without the application mentioned before.
