3.7 million people per year visit Yosemite National Park and its one of the most heavily visited National parks in the US. Despite that fact its very difficult to get cell phone coverage in the area.  Its an important safety issue to note especially if you are hiking in the park or plan on staying for an extended period of time. As you can see by the carrier coverage maps below from the four largest wireless service operators AT&T, Verizon, Sprint & T-Mobile that cell phone coverage in Yellowstone National Park is not good and spotty at best given the terrain and trees. It is also virtually impossible to discern the projected coverage on the carriers' maps despite having 250 combined customers and billions in profits.  See our post on cell phone coverage in Yellowstone National Park as well. 

Carriers don't care about where you need coverage the most and would rather spend their money telling you they are full of _ _ _ _!.  So Deadcellzones.com can help and has provided a user generated coverage map and would appreciate your input where you think there should be cell coverage and wifi provided in the park by submitting pins directly to our Yosemite cell phone coverage map. After you click on the link or go to Deadcellzones.com, type in the zip code 95389 of Yosemite and add a pin in the area you had a problem expected to have coverage in areas throughout the park. Feel free to submit coverage problems of other National parks as well because these areas will likely be targeted by the FCC to provide free national broadband.
