My family is about to open a new business - a mobile food trailer - here on the coast and we’re trying to figure out what cellular service to get.  Our food trailer will be moving all along the coast, as far north as Montara and as far south as Pescadero.  Sprint has the cheapest wireless plan we can find but I don’t know how their coverage is on the Coastside.  Does anyone here have personal experience with Sprint?  Thank you.
