Samsung S10 / Android 11 - dual sim problems. - Samsung Galaxy S10 Questions & Answers

Hello, I got several issues with the Android 11 on my Samsung S10, could You please try to help me with these ?
DESCRIBTION of facts thats apply to all the below issues:
SIM1 is my default/main card for all activities including data. And I want it to stay that way all the time.
SIM2 is my additional card and I want it to stay that way all the time, except when I turn off SIM1.
ISSUES:
1. When I receive mms on SIM2 I can`t see it. I only see a message to download it. When I try to download it, I see a system message: "Receiving multimedia messages will temporarily disconnect your device from the mobile nbetwork currently in use". When I agree to that, the phone tries to download the message. But with no success. If I really want to download it, I need to change that SIM2 get the prioryty to download data. Is it some bug ?
2. I need to turn of one SIM card from time to time (exactly when I sleep ). I would like to have a widget for it, but I see none in Play Store Did I miss something? What I achieved is only that I have made a shortcut with [Shortcut Maker] programm that takes mi directly to [Setting/Connections]. Is it possible to have a widget or at least a shortcut directly to [SIM card manager] menu in the Setting/Connections ??
3. Even if I manage to turn off one SIM card with the [Settings... SIM card manager], I still have some trouble. It takes too many steps to achieve what I want to do. What exactly is the problem ? My SIM1 card is the default one as I described above. SIM2 is only for emergencies and noboy except my family knows it. So I turn of SIM1 for the night. Automatically alll the actions goes to SIM2 (calls, sms, data), as one card have to stay turned on). Thats ok. But then, in the morning, I turn on SIM1. The problem is that all the actions stays in SIM2 ! To fix it I need to take the following steps:
- turn on SIM1 (actions stays in SIM2 :/ )
- turn off SIM2 (actions moves to SIM1)
- turn on SIM2 (actions stays in SIM1 and SIM2 is back online)
WTF ? Should it work that way ??

Problem: sim detach notifier

I have a problem with my Galaxy Tab! Εvery now and then my Galaxy Tab give me a black screen with problem name: sim detach notifier and then my tab restarts alone!! Is there any solution for this problem?
Edit: I searched on Google to find a solution and i found that is a problem from the Sim card....., it is dirty or something like this, and now i'm using another one and it is ok....! Any ideas?
suggestion: freeze sim deta chnotifier with titanium backup
This problem happens to me too, time to time.
Freezing sim detach notifier with titanium backup should fix this. In fact, I have just checked that after freezing, if I really detach the sim card nothing happens and the tab does not reboot.
EDIT.
It is still possible that the sim card becomes "detached" after freezing sim detach notifier. This happened to me one time yesterday. However, the tab does not reboot, you just see the "no sim card" icon in the notification bar and of course you cannot place and receive phone calls, surf the internet, etc.. To enable this again you just switch to airplane mode and then go back to normal mode. By the way, when looking at the alogcat messages I noticed that the system keeps on calling sim detach notifier forever after the "detach" event: as soon as sim detach notifier is unfreezed, the tab does reboot...
This problem was big for me and I had to get a new one in the end. I've heard other tab owners who had the same problem, so maybe the tab is sensitive for problems in this area.

Whatsapp and LTE/HSPA+

Hey guys, i've got a very special problem i think. I have two sim cards in my XZ2. Both are registered in 4G. Now everything works fine. I can use every app and download files. The only thing that doesn't work is Whatsapp. If i switch to H+ then Whatsapp works but not in 4G. I had a lot of android phones but this never happened to that only one app doesn't work on 4G. Has anyone experienced something like this and can help me/give me an advice?
Edit: After trying to fix this Problem i think there is following situation: in the settings you can choose the sim for data connections. For me its sim 2. But whatsapp is trying to connect to the internet over sim 1. when i change the sim for data to sim 1 everything works fine. So imho this has to be a software problem. I hope sony will fix this soon. Do you think talking to Sony support might help?

Hi heildnix, I have an XZ2 Compact, my situation is: SIM1 LTE/voice, SIM2 only voice. I've set SIM1 default for all (data, voice, ecc). all works apparently fine, but! I don't know why WhatsApp try to use SIM2.. so if I have SIM2 active WhatsApp does not work..
I opened a ticket to WhatsApp and Xperia Care and... if I went for a bike ride I would have obtained more results

Weird roaming problem with every s3 mini custom rom i tried.

Hello to the forum.
Strange problem. I have tried many,many roms of the mini s3 forum (resurrection,cyanogen,omni,etc) from 4.4.4 to 5.1 and 6.0 and with all the roms , i cannot roam.
As soon, as i press call button,call has ended. If i use local sim,it works. If i use the roaming sim to other phone,it works. If i use stock rom instead of custom rom on the s3 mini, roaming sim works. I 've spent 3 days changing roms, resetting all app preferences, deleting dialer data ,selecting 2g network, showing or hiding my id during calls, enabling,disabling caller id service and i can't make it work.
If anybody can give any help, it would be very much appreciated.
Some more information that i noticed.
When i put the sim card in another phone that roaming works, it goes like this.
When it connects to a network it says "callback mode enabled" and whenever i make a call , it says something about "ussd parameters" and it calls my number first and i must accept the call , so it can automatic dial the desired number.
In all the custom roms i've tried ,none wrote anything about callback mode and ussd parameters. Can i manually do sth to enable them ?
Well, after weeks of custom rom's installations, after reading every existing internet forum there is, after having tried every combination imaginable, i did the most complex thing i could have done. Communicated with the telephone company....
They gave me a code of a *145*number# form that goes before the international prefix, so i can use direct roaming instead of calback mode that somehow can't be enabled.

Sony SOG01 Simlock Or...(please read the thread)

Hi all. I hope someone can help me with my phone.
I have this phone and I have problems with it. The phone was bought from another person, not in a store.
It does not connect to the mobile network and cannot connect to the mobile internet.
It is fully operational, all functions work (except for the sim card), the phone connects to wifi and connects to the Internet. When connected to a computer, it is also completely determined.
You ask, "So what's the problem, take it to repair, they will replace the SIM card module and everything will be fine"
The problem is this. The SIM card is fully defined in the phone. When installing a sim card, a reboot is triggered, the operator is determined in the settings menu (I am from Russia, therefore my operator TELE2, the sim card was bought specifically in order to exclude the old generation of sim cards and also a possible simlock to my other operator), but when you click on the sim card menu, calls and SMS the buttons are grayed out with the caption "temporarily unavailable" (if necessary for understanding, I will change the language of the phone and provide all screenshots of the system) and they cannot be clicked.
Also, in the engineering menu, in the simlock button, opposite the Network subset inscription, there is the number 5 and it is marked with the letter X. This means, as far as I know, that there is a lock on a specific operator. But after a hard reset, the phone does not ask for any codes to enter.
This is my question, how can this be fixed?
Will flashing the phone to global rom help?
I gave the phone to a service center (not a Sony branded center, we don’t have one in our city), they told me that software setup was needed, but there was only a chance to restore the phone.
Maybe I need root access and find some file in my phone?
Please help me.
P.S. I don't have the best English, so sometimes I can't understand you, please don't get mad at me)
P.S.S. I created this topic in the questions section. I'm sorry if I had to go to the firmware section
