Hello Everyone,
What does native dual sim support by Android actually mean to us? Does it mean that CM sources for 12.1 will also support dual sim? And all the System ui FC's various other problems that the dev's face due to dual sim, will vanish from 5.1?
Does it also mean, dual sim devices will get more roms and get to enjoy all the features that were limited just for single sims?

Afaik dual sim support improvement is only cosmetic (labeling of sims, a bit more clear)
How it is implemented is up to the manufacturer (motorola) because hardware needs to matched up with string/codes etc.
CM can only guess what strings and lines to use/implement to enable dual sim BECAUSE they dont really know how the hardware works (only motorola does because they have the sources etc). Thats why motorola is able to implement dual sim properly on stock roms at a much faster rate.
Theres also the problem of CM not rly supporting dual SIM, so the codes that CM create (after modifing the AOSP code) dont really support dual sim, hence system UI fcs and such.
So thats why a lot of guesswork and trial and error has to be done by whoever wants to make CM compatible with dual sim on falcon. Nothing works out of the box if your phone is a non nexus device and even worse if its a non nexus dual sim. Its easy for CM to guess what has to be done to support single sim devices.
A lot of people need to understand this.

But then, why do they have to proclaim " support for multiple SIM cards" as a new feature?
According to my knowledge, dual sim support was added by the individual phone manufacturers until now.They had to somehow "emulate" a dual sim support. So, even CM had to do it till now. it was a bit difficult since Motorola had the sources and CM did not. My question is, Since it is included in the OS itself from 5.1, do all the hassles caused by the dual sim alone, vanish from 5.1? The implementation of dual sim support by the phone manufacturers/Cm is not necessary anymore(since it is present in the source itself)?

Like i said earlier, it depends on how CM’s code work, or other rom's code work. For example dirty unicorn etc they dont BOTHER to support dual sim. They pick the AOSP codes that reflect that. CM sorta works that way, hence people wanting to port CM to dual SIM having to do their own bit of coding to make things work.
A lot of those dual sim lollipop improvements are cosmetic if im not mistakes, youll have to see for yourself. Even then, it goes back to the rom maker to support dual sim or not.
Android 5.1 GPe is made by Google and they didn't add the support for Dual Sim.So, you cannot get Dual Sim on Android 5.1 GPe.

Proof in the pudding
Hi everyone,
Weird question but all the CM 5.1 roms I have tried so far have no issues dual sim wise.
In fact one of the ROM builders expected the dual sim to work without issues even though he never tested it. ( He doesn't have dual sim moto g)
My question is how is CM or these rom builders doing it while others are not?
Links below I have tested dual sim on my phone, USSD, places search in dialer, 2g and 3g are working without a hitch. (I prefer the 1st link because there are no issues controlling chromecast volume while screen locked.)

I am about to get a new phone and I am quite lured by Moto G but the only issue is that we only have dual sim model available here in India. I don't use more than one sim, So, I just wanna know is there any difference in User Experience, ram usage, battery life and Rom development between the two models. And also is it possible to use single sim model's rom on dual sim model? Thank you very much.
I only used a normal cellphone as dual sim before, but with that the battery life was decreased big time because both sim cards had a constant connection.
Might be different on android since you might be able to change more settings than with an old cellphone, but it is definitely a danger to battery life.
The OP's question remains unanswered
The OP's question remains unanswered. Does battery life performance of a 'Dual SIM' model reduce(at least considerably, say by at least more than 1% ) compared to single SIM phone even if the second SIM slot is kept vacant?
A GSM arena comparison of Xperia E1 models (singe Vs dual Can not post the link due the forum limitation ) does show a reduction in battery life, however, they haven't mentioned whether the performance was checked with both SIM slots occupied by functional SIM cards. I've already written a query to them, would post the reply here in case I get one.
Would be great if others can share their experience on the subject. :angel:

So, the dual-sim version uses more battery in order to make the two sims work, but I think if you'll only use one sim, u can go ahead and buy the dual-sim one, after, u can convert your XT1033 into a GPE or in a XT1032
Hi guys!
Could you help me in identifying the right version for me?
I'm currently on samsung galaxy s advance with Carbon kk rom.
My 1st dilemma is - dual sim or not, knowing that nonstock rom is a must. I believe cm11 now supports dual sim. The price is the same. I would mainly use just one sim, 2nd only when in roaming.
My 2nd dilemma is - 8gb or 16gb version. I wont be playing games, dont have music and video collection.
Other advices would be kindly appreciated...
Definitely get the 16gb if you can, since it's only a little bit more expensive and you get about 13 GB of free space instead of 5 GB.
Dual Sim. 16 of course
Sent from my XT1033 using Tapatalk
Definitely 16GB, more the better when it comes to storage.
If you like playing around with your phone flashing different roms then dual sim isnt for you. Otherwise I don't see why you shouldn't get dual sim phone.
I like playing with roms , thats why i waited for custom rom 4 dual sim to show up. As i see now, cm11, slimbean and others, do support dual sim?
Q: if only 1 sim is onserted, does the phone functions like single sim then, i mean completely?

Really? Is that a thing? I have never heard of such a thing as dual SIM causing the phone to lag or anything.
It certainly depends on your preference. As far as I know, Dual SIM phones are great since you don't have to carry multiple devices, which can be a good thing or a terrible thing. Good thing because one device, duh! Bad thing because, two connections, 1 battery. But if you are like me and don't care for carrying too many devices in your pocket, go for the dual SIM. It is great and it certainly doesn't lag.. (where'd you read that it lags?)

I use single sim. and it's fine. I never heard of the phone lagging on dual sim.
What I can say is, it's depends on what you need. If you don't want to carry multiple phones, buy the dual sim.
especially more people (at least here) uses dual sim, and also more custom roms are available for the dual sim.

Thank you dear william tanaya, I want to use one sim for general communications such as Calling, SMS and MMS... and other Sim for internet DATA. So Dual sim is necessary for me.

there you go. you find the answer. I hope everything going well for you. this phone may not be perfect, but it's awesome
I've just got a U12+ with dual SIM support (not a conscious choice, it's just what was available). I never intend to use the second SIM slot (for extra memory yes, but not for a SIM). Is there a way to make the system behave like a single-SIM system?
There are several places where extra SIM info displays, and it's all superfluous and makes more noise in the UI if you only use a single SIM. For example the carrier name at top of screen is followed by "(SIM 1)"; the cellular signal has a "1" next to it; when a text arrives it has an icon next to it; and the text send button says "SIM 1" next to it. (Update: For the last thing, the text is modifiable via the dual sim manager, cannot be empty, but a blank is accepted, so that is gone, but only from that one place it seems.)
There are probably other places where "SIM 1" is shown. Is there a way to turn off all the extra SIM 1 stuff? Pretty unimportant, but would be nice...

Hello Time Lord,
There is no solution for this yet.. Maybe Viper U12 can do it, or it will can do it. I didnt try this yet, because its beta status (but im really happy for Viper on U12, thanks for the developers! ).

The more I think about this... the dual SIM support and behaviour is probably more about how android works, right? It's not really specific to this device, but would occur with any dual SIM phone? If so, the question/rfe should be redirected to google...
Hi,
I have dual SIM version of the Velvet. Previously I used Xiaomi MI9 (also dual SIM), and when I switched I was so surprised the way you get to choose from witch SIM card you are making a call. Is that really it that in LG you need to choose SIM card in notifications menu before making a call?
For example MIUI gives you different options, one SIM to be default or ask before making a call, or you can always tap and hold contact to choose a SIM card...
That's weird, or am I missing a setting?
Hi have you had an answer for this? I'm hesitating between this and a Xiaomi device and dual sim usage is really important to me

No, I just got used to it, that I must double check which SIM card is currently selcted. It's annoying but well... it works, though. I switched from Mi9, but it had terrible battery life. I still see people annoyed from battery problems in their Xiaomi.

You can always preset a SIM card to certain number.

Hi thanks for answering! I can get the Redmi Note 10 pro and the LG velvet for the same price; that's why I have been hesitating, but my current phone is still working so whichever is cheaper will be my next phone haha
How is your transition from MIUI to the Velvet UI? I have never tried MIUI before but from videos I have seen, I really like the way it looks, LG's UI on the other hand, I still have mixed feelings...
Velvet UI and MIUI are a bit different, but can't tell which one is better. Maybe one thing I miss is gesture navigation. I have chosen Velvet because of Dual Screen case - the one thing that distinguished that phone among others.
