Yosemite Cell Phone Service
Cell phone service in Yosemite is spotty because of the mountain terrain and may not always be available. However, there are a few places where you're more likely to get connectivity with the right provider.
Voice and 4G data service are available in parts of Yosemite Valley and Tuolumne Meadows. Signal is strongest in the Yosemite Village area near the Visitor Center.
Voice and 4G LTE service is available in Yosemite Valley, centered around Yosemite Village. Voice and 3G data service are also available in Crane Flat and just outside the park in El Portal. Verizon’s voice service is available in Tuolumne Meadows and Wawona.
