I am pretty sure that every wireless carrier is going to have issues once in a while in some form or another, So good luck with your switch. My experience has always been that Verizon sells a superior service for a bit more money (at least in Portland Oregon) so I always return...

T-mobile= only works in city 

sprint= pure garbage

at&t= a close second to Verizon

Good luck , this is not a Verizon employee
