I'm currently looking to get into Graphene. If I do, I'll use an 8 or an 8 Pro.
I use 2 sims. Sim1 is for my phone number, and texting. Sim2 is used for all of the phone's data. My employer pays for Sim1 but it has a super low data cap. I pay for Sim2 and use it really only for data. At the end of the month Sim1 uses about 100mb and Sim2 is up there, 10G to 15G.
I'm not concerned at all about using different sims for calling and texting.
I was able to do this easily on an iPhone 12, but I'm not an iPhone fan ...
I used to be able to do this on a S22, but after a recent update, the option is gone.
I THINK this is an option on a vanilla Android Pixel.
Can anyone confirm it deny this as a working option in Graphene?

Yes if you have dual sim you can choose which one will be for data. But you probably already know that one sim needs to be esim.

That's great news. I think I'll be diving in soon. Thanks for replying.
