NY/NJ Signal on bridges

Folks - how is the AT&T wireless signal on tunnels and bridges in the New York New Jersey Connecticut area. I ask because I am currently on Verizon and always have choppy audio on zoom calls. I am contemplating buying a device that couples both network cellular connections and passes traffic to the most reliable one at all times but if AT&T is as bad on bridges, then it obviously won’t work.

I also haven’t tried this on Verizon yet, but would it make sense to turning off 5G and just using LTE because I suspect when it switches between LTE and 5G that’s when I suffer choppy audio. For me reliability is better than speed.

Thanks
