Before I attempt to install an Android 10 based custom ROM on my phone, I would like to know if any of them support independent toggling of the SIM cards? For instance, can I toggle SIM 1 to be off/disabled while leaving SIM 2 on/enabled? Looking forward in any suggestions. I'm leaning toward trying out Havoc, but before I go through the process of installing, I'd really like to know if the SIMs are independently selectable.
Cheers!

Hello everybody!
I'm a user of Lenovo A536, and soon i decided to customize it. So i wanted firstly to install fresh version of stock. My phone is single SIM version, and after few hours of googling it looks like there is not singe SIM version firmware available for download. I tried about 5 different versions(last digits of releases):
*910
*725
*141115
*813
and maybe one more... And all is Dual-SIM.
After installing DS Stock ROM, everything seems OK, but, there is network issue. I'm available to use just GSM(2G) networks. My default SIM is SIM 2, not SIM 1 where WCDMA(3G) is setted by default. (Why is this really important to me: most of a day, i'm not at home, so slow network is like i don't have it. ) In SIM Managment there is no another SIM. Just SIM 2, and when i click on it, there is two options, SIM 2 and "off".
What have i tried more:
CODES
I have tried to dial *#*#4636#*#* but, i got two phone infos(Phone info 1 and Phone info 2) and "radio off" is not working as changing mode, on both of it.
Build.prop
I have looked what is seeking there... I saw option something like "...active.sim..." and it has value of 2, and i set that to 1, but that caused bootloop after rebooting....
APPS
I have downloaded some SIM Managers and try to enable/disable SIM 1, and to set 3G to SIM 2, but that was unsuccessful also.
Is there any way to change some system file which contains these settings, to disable one SIM, or just to change SIM 2 to SIM 1?
Or can you find correct singe SIM ROM?
I'm currently on MIUI 8.
Thanks to everyone for attention.
(I'm sorry to MODS if i have posted this thread on wrong place, or named it incorrectly)
I've tried about 4 of the main roms right now that have a rom based on the new 7.1 and every single one, my APN doesn't work. I can switch it to get H+ to work but LTE doesn't work on any of them. It's not the network, I can switch back to my other rom just fine and it works but none of these roms appear to work.
I recently got a Xiaomi Mi5, the stock ROM does not support Wi-Fi calling, so I needed to flash it since I work in a basement...
I now have Resurrection Remix installed, and Wi-Fi calling is available and toggled on, but it does not actually work!
I know it is enable on my sim because I have been using the feature for a year on an iphone... and the provider confirmed they did not lock anything up or needed to reset anything.
Any ideas out there?
I can't think of any way to even debug this issue, apart form flashing to different ROMs, but that takes a while and I like RR.
Thanks
Currently on Oreo...
I recall reading somewhere a change has been implemented in Pie with respect to Travel Sim use; it is now necessary to re-flash a new rom before new travel sim card can be used in a different country, is that correct?
Anyone know what the process is with respect to getting a pie flashed phone working with a new destination country sim card?
Hello,
I used iOS the last years but want to switch back to Android/customs roms. A few years ago, when VoLTE started to become available, I remember that it generally only worked on android when the phone had the carrier firmware.
A few days ago, I tried an unlocked phone with a non carrier firmware with my sim card, and volte and vowifi worked immediately. I cannot find any information how this is implemented nowadays. Is there any relation with Google carrier services? Or do modem basebands include these settings? Where is this information stored and does volte and vowifi on newer android systems "just work" as long as the carrier supports it? I'm just curious how it works, and if LineageOS for example does support it.
Thank you!
