well, after looking at the map I'd say they are pretty optimistic. There are areas on the Map in Idaho, mt, and eastern oregon that show 100% mobile coverage and myself and others have verified coverage is zip, zero, nada even with a cell booster for verizon, ATT, and others.
The spots that show 0 coverage, Spots they show 0 coverage that we have traveled in are pretty spot on. Agree with that
