Cell coverage at Yosemite still in the Dark Ages

AT&T Antenna in Valley

 This is the main download station in the valley for ATT. It is located just north of the Valley shops. By reciprocal agreement, service in Yosemite is provided by Golden State Cellular. Carriers pony time for their services. It’s kinda like the telephone lines in your neighborhood. One company owns thenm and others pay through ageements to provide their services.


Verizon Wireless has the best connectivity for both voice and 3G data service in parts of Yosemite Valley and El Portal. Voice and 1x data service are available in Tuolumne Meadows, Crane Flat, and Wawona. (Note that data roaming must be enabled on your phone to use data.) They are best in the east end of Yosemite Valley, and weak at Tunnel View. Verizon seems to be very good at Glacier Point and the top of Sentinel Dome. Reception is excellent on the Yosemite Falls Trail and the lower Mist trail. Don’t plan on much at Tioga Pass, but coverage is excellent all along 395.

Here is the best coverage map I could find for Verizon: 

 AT&T ranks 2nd in user experience with both voice and EDGE data service available in parts of Yosemite Valley and Tuolumne Meadows. Coverage seems ok the high country along Tioga road. You cannot get 3G, but edge works great, and this is expected for rural areas.

Here is the best coverage map I could find for ATT:

 Sprint and T-Mobile are very poor at the park. They have no dedicated program there and you’ll have to roam to use them. Roaming really drains your battery, so turn it off until you need to use it.
