I'm running the stock 4.4.4 ROM on my Moto G 2014 Dual Sim XT1068 Titan. I have a Sainsbury's SIM in SIM1 and a Three SIM in SIM2, which is also the data SIM.

I don't get very good reception in my flat on Three, so often when I move from room to room, I lose the signal completely but this causes a notification to appear saying that I've lost signal on the Sainsbury's SIM, even though that's showing full bars at the time. Even when I get signal back on the Three SIM, the notification doesn't go away and the only way to get rid of it is to tap it, which then opens the Mobile Network selection screen and takes ages to scan for networks before I can select one and close the screen.

Has anyone made a patch that fixes this annoying bug, ideally to make it not show any notification at all when the signal is lost, so that it can just resume silently when it's found again?

First of all, I want to say that I know CyanogenMod or any other similar ROM doesn't support dual-SIM officially.
There have been many ROMs that support dual SIM, but most of them are just MODDED ONES.
I have read about this in many places, but I don't know how to mod a single SIM ROM to support dual SIM phones.

For details in specific, I own a Karbonn Titanium S5 Plus (Mediatek MT6582 SoC) that uses dual SIM. Sure, there are many Jelly Bean ROMs for my device, but none from popular developers like CyanogenMod, ParanoidAndroid, SlimROMs, etc. I want to port one, but most of the ROMs that suit my criteria as a port ROM don't have dual SIM support. My device has no kernel sources, and so, has only 4.2.2 based ROMs.

So, my question is, HOW DO I MOD A ROM TO SUPPORT DUAL SIM ?

Hello,

I recently started playing around with Custom roms on my XT1068 and was kinda disappointed by the Multisim Management in CM12 based ROMs compared to stock.
The Stock solution is nothing too fancy it just allowed to assign a color and a Name to each sim and to remember the SIM choice per Number for SMS and voice calls:

I only found one third party solution - Dual Sim Selector (net.pixelrush.dualsimselectortrial in Play Store) which emulates this behaviour.

Is there any way that the stock SIM management solution can be integrated in CM12(.1)?
Are there other solutions/ROMs out there which offer equal functionality?

thanks,
