Hey y'all, just wondering, for those of you using 2 phones or a "dumb" phone, how does that work exactly ?

I figure, for 80% or so of my time I do not need my s23. So id like to swap my Sim card into a dumb phone for most of the time. However when I travel or other things that I want more computing power in the go, I want to swap it back to my s23.

I'm not sure if this works as seamless as I'm thinking, and also, I only have an esim in my s23 since I changed from Verizon to at&t.I heard I can just walk into at&t and get a physical Sim for free?

Sorry, a little more phone related than privacy related. But I'm trying to get away from Samsung but I'm not ready for a pixel yet. And I don't really want a smartphone all the time anyway.
