Which statement is true regarding mobile network coverage?

Mobile network coverage can vary significantly based on a multitude of factors such as the service provider's infrastructure, geographic terrain, and population density. The statement indicating that some areas may lack mobile coverage is true because not all regions are equipped with network towers or antennas sufficient to provide consistent service. Rural areas and certain urban zones may experience weak signals or dead zones due to insufficient development or investment in network technology by service providers.

While larger urban centers typically enjoy comprehensive coverage due to higher demand and investment, more isolated or less populated areas often face limitations. The presence of physical obstacles like mountains or buildings can also interfere with signal strength, further contributing to patches of poor or nonexistent coverage. Thus, it is a widely acknowledged fact that mobile coverage is not uniformly distributed and varies from one area to another.
