You won't be able to pick up a clearance on the ground at any airport outside of the coverage area. However, since this is a "simism" and the problem doesn't exist in real life, even if you're in class A airspace, just keep on coming and call the nearest center sector as you near the boundary. If you end up in the PE coverage area in class A airspace for a few miles before you call, it's no big deal. The controllers will understand. At that point, you can just treat it like a pop-up IFR clearance.
