GaiaGPS - cell coverage map layer
GaiaGPS, the favorite backcountry GPS phone app for many outdoors folks, keeps adding map layers at an impressive rate. (To be honest, it's hard for me to keep up on all of them, but I try.)
As of June 2020, there’s a new one that might be useful for some folks.
It's a cell phone coverage map of the United States, which shows where in the backcountry you're likely to receive a signal. There's a layer for individual carriers such as Verizon, Sprint, AT&T etc, and also a layer for “all carriers”. The darker the color, the better the signal, at least in theory.
Should you be yapping on your phone and checking social media in backcountry? That's a question you get to answer for yourself. =^)
Should you be yapping on your phone and checking social media in backcountry? That's a question you get to answer for yourself. =^) But, if you have a backcountry emergency and need to get somewhere where you can make a phone call for help, or you're on a long backpacking trip and want to check in with folks at home before you move into an area with no coverage, this feature could be very helpful.
This map layer is available only on the Gaia Premium level of membership which typically is $40 a year.
As with all Gaia map layers, you need to download these to your phone while you have Wi-Fi (preferred) or a cell connection.

Let's start out small scale to large scale. Here is a good chunk of Colorado, Verizon layer.
How about Yosemite National Park? Good coverage (Verizon layer) if you're in the Valley, but not much anywhere else. Minimal cell coverage in an alpine wilderness; isn't that how it should be?

A final zoom in to Mt. Rainier National Park. Hgh up on the mountain coverage should be good, but down in the lowlands driving into the park and even at the main Paradise visitor center, probably not. (This is the “All Carriers” layer, and yes that magenta color is a little strong on the eyes.)
