Sure. Download the offline version before going into the mountains.
Download offline maps in advance and test them. There will be no signal in the suburbs.
The Grand Canyon and Antelope Canyon basically have no signal. You need to download Google offline maps in advance. I had zero signal on my phone for the two days I was there. The desert begins and the signal basically disappears. You don't even need to go into the mountains. I am an ATT signal.
At least some sections of Highway 1 do not have signals. I use an AT&T card.
