S24 Ultra: Unable to choose different SIMs for phone calls and cellular network usage

[adrianyepremyan]

Hi. It's been a week with my new S24 Ultra, and one thing that really bothers me is that I am unable to use my SIM1 (physical) for phone calls and SMS, and the SIM2 (eSIM) for the cellular network.

There's no such option to choose in the Settings app. I am able to choose only the Primary SIM, which uses the chosen SIM for everything, which is not useful in my case. I saw a similar question asked, but there were no solutions posted. I wanted to know if I can use two eSIMs at the same time, and if by doing that I might be able to have more control over them or not, because I can swap my physical SIM with another eSIM easily.

Thanks a lot for the information, it is really helpful to at least know that it is officially not supported, though I really don't get the reason why one model supports the feature and the other doesn't...

Do you know if it is a hardware limit or it is possible that with future updates it might get fixed / support added?

eSIMs in QR codes that require a manual activation code entry cannot be used (4th screenshot). None of the carriers in the United States require an activation code to be entered manually. For example, if you activate a foreign SIM with Gio (India) and it asks for an activation code, here's what would happen.
• US/CA models: "eSIMs from this country/region cannot be added"
• International models: "Enter Activation Code"

Cross-device eSIM transfers were removed in One UI 6.0. It is not clear whether they would return in One UI 6.1 for the US.

This is very annoying, like annoying is the problem of the camera that change the saturation of the color after I take the picture, and make terrible and fake colors. This is really an annoying and there's no way to stop that.  I'm very very disappointed of this phone. I'm gonna ride off now. Very annoying Samsung. 

I regret that II sold my s23 ultra to by this bs new model!  

Wake up Samsung!

Am experiencing the same problem with US Unlocked Version S24 Ultra SM S928u1. It's utterly frustrating that a simple functionality as being able to use 1sim card for calls&text and the other exclusively for Mobile data only is missing from such a flagship.

If this is a software limitation we hope and pray that Samsung can fix&add the functionality in future updates😏

How can we unmark this as not a solution , will samsung still look into this if marked solution ?  Even my s20 plus still has the feature ,but s24 ultra doesnt will this be fixed in these variants ?

I was expecting fix on this in the UI 1. But, they have not fixed it. It sucks.

How about the B variant? I can only choose sim 1 for mobile data usage. I wish to choose my esim as an option but not in the choices 😞

I can do this with my pixel 8 pro in USA. I don't understand why it was removed if even my basic older pixel phones can do this. It's asinine to me that Samsung removed this feature. I have to use another phone because of this dumb limitation that a flagship removed.

This works on sm-s928u1

That does not work. It only says switch to switch to primary sim for data, calls and texts. There's no option like this with the U1.
