I have Verizon on my work iPhone. I used the iPhone for meetings yesterday and today remotely. No issues whatsoever.
One thing I've noticed about Verizon over the long term is their data speeds look great if you do a speed test with Ookla app, but in real world, I'm noticing Verizon gets very slow for 10 minutes (so slow you can barely use it), and then it will speed up.
In my area, AT&T has slower 5G than Verizon, but AT&T's speed is extremely consistent (it doesn't slow down),
so I can rely on AT&T more than Verizon for data.
