Is there cell service in Yosemite? Area by area
Yosemite Valley has AT&T and Verizon LTE, Glacier Point only AT&T, Tuolumne almost nothing. What the National Park Service publishes, and what that means with a travel eSIM.
In Yosemite Valley, yes. Elsewhere in the park it depends on where you are and which network you are on. The National Park Service publishes the picture: LTE from AT&T and Verizon in the Valley, mostly its eastern end; only AT&T at Glacier Point; almost nothing in Tuolumne Meadows.
Our United States eSIM connects to AT&T and Verizon, so it gets whichever of the two covers the spot you are in.
