Does the AT&T model support both sub6 and mmwave?

And can similar be said for Verizon (mmwave only) and T-Mobile (sub6 and mmwave)?

I guess it’s definitely mmwave but does the latter mean sub6 (including mid band)

or just low band?

Samsung site says this. But that’s still not very clear. I don’t mind Verizon only having mmwave but what about T-Mobile and AT&T? Thanks

Edit: I know the T-Mobile version supports both sub6 and mmwave. So it’s just AT&T I guess

I guess I found my own answer. Thanks!
