Wyoming is the least densely populated state in the contiguous U.S. Caregivers may drive an hour or more between clients. Much of the state — the eastern plains, the Bighorn Basin, the Wind River country, and the land between the oil and gas communities of Gillette, Riverton, and Rock Springs — has cellular coverage that would be considered frontier in any classification.
GPS-dependent mobile EVV apps require both cellular data (for internet connectivity) and GPS signal (for location verification). In Wyoming's frontier zones, either or both can be absent. A caregiver who genuinely checks in at a client's home may generate a GPS location exception simply because the technology can't establish a reliable fix. Those exceptions flow into CareBridge and must be resolved manually before billing — creating administrative work that is entirely disconnected from actual care delivery failures.
Telephony-based EVV — calling from the client's location — generates a verifiable time and location record without GPS or data dependency. Under Wyoming's Open model, this is an accepted and often operationally superior approach for agencies serving frontier service areas.
CareBravo manages Wyoming's CareBridge exception queue daily, including the connectivity-related exceptions that are disproportionately common in frontier service areas.
