dual sim S21 ultra

[Aligater]

I previously had an s10+, when having dual sims in I was able to select which sim to use to call numbers or txt I now find this facility is missing, if I need to call a number with my second sim I have to either delegate that number to use that sim or switch overall control to that sim.

This feels like it's gone back in technology to how it used to be when you physically moved a switch to switch sims 😕.

Is this a common fault/new or is it my phone

It seems to be how Android 11 with Samsung One Ui 3.0 now deals with dual sim.

If you perform a search on the forum you will come across existing threads on this too @Aligater from people using your model of phone and others using different models too so it's the software.

A person can send feedback direct to the Samsung Development Team via Get Help in the Samsung Members app.

Maybe if enough people send similar feedback then Samsung will take note.

Perhaps take a look at these.

Hi,

This was a question I would like to know the answer too. I don't think it is supported but wish it was.
