When you live in a remote area, carrier coverage maps are supposed to help you choose the best service for your location so you don't end up with no signal at all. To no one's surprise, a test conducted by the FCC brings to light that some mobile internet providers tend to overestimate the speed and reach of their network — you could even conclude that they're outright lying about their coverage about 40% of the time. The carriers blame the FCC for their inaccurate maps and claim that they just followed the agency's instructions on how to submit coverage data, which they say led to the overestimates, understandably.
