so I finally got my s22 ultra since my s21 ultra wasn't "firstnet certified" and I have to say, the speeds are definitely slower than verizon, at least in the areas I tested. I'm around a lot of c band for verizon so I was clocking 300-400 mbps on average as opposed to 60 to 120 on firstnet. however, so far in the areas I've been in I have consistent useable service, so consistent that I've been on band 14 the entire time no 5g. I have way better indoor coverage in my apartment than verizon, and my phone calls and text have been on point. I'm definitely looking forward to trying out more places to conpare coverage and performance.
