Reviews of an area’s cellphone coverage are available at CellReception.com. This site hosts a database of users’ reviews and comments about the coverage of major carriers in a particular area. Site visitors enter a ZIP code to access the reviews and track overall carrier coverage and dead zones.
Each review features a one- to five-star rating, the reviewer’s location, and comments.
Gaps in cell phone coverage occur when there is little or no overlap between cellular transmission towers. As user load increases, more towers are necessary to sustain volume. CellReception.com features a map of cellphone towers in each location, as well as past issues encountered with specific carriers. Additionally, the site has information about how cellphone reception works and reasons for poor reception, such as low-power transmitters.
