A cellular network consists of several cells. Each of the cells is serviced by a base station operating with a specific frequency. Adjacent cells are each assigned a different frequency. A non-adjacent cell will be able to use the same frequency without interfering.
Flat-Earthers like to tell us that a single satellite can cover an entire country, yet phone operators choose to install base stations everywhere instead. Then they use the fact to “prove” that satellites do not exist. In reality, a cellular network has several advantages compared to one single base station, like a satellite.

Switching is used to establish a telecommunication network between two non-adjacent communication nodes. The information is relayed by one or more intermediate nodes that might use very different means of data transmission.
In 1969, President Richard Nixon called the Apollo 11 astronauts from the White House using a landline phone. Flat-Earthers regard the fact as ridiculous. According to them, if we cannot reliably make a phone call to the next room, then it must have been impossible for President Nixon to make a phone call to a location 384000 km away using a corded phone. Such allegation only stems from their lack of understanding of telecommunication.
