Yes, Verizon, Switzerland is in the United States. (As is Bolivia.)
It's true. Who knew?
As you're flying down I-95 South, just before you cross the border into Georgia, there's a sign that reads "SWITZERLAND."
It was late and dark and I didn't get a chance to pull off and see it, but there is evidence of its existence on Google Images. (Turns out, there's a Switzerland, North Carolina, too. It's in the Appalachian Mountain Range.)
As for Bolivia, it's in North Carolina. Down near the border with South Carolina.
