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.
