Yea, of course any plan is coverage dependent. My area is pretty well covered and I haven't noticed any issues in that regard. I was already on Verizon and Visible is the same network, so nothing should change there.
But, I'm sure that I'll somewhere at some point and not have great coverage. Par for the course. The only thing I can suggest is multiple providers if that is your case.
As for peak times, I haven't noticed anything bad there either. My guess is that while Visible is a MVNO, it is the main MVNO for Verizon. As I mentioned, I get the strong feeling they are Verizon v2, it wouldn't be in their best interest to provide too bad of service.
