Technically, it’s ‘pipes’ not ‘wires,’ but they function the same.

When you hold the phone in your hand while standing on the ground, you’re closing a very long circuit that connects everyone via underground ‘electro-acoustic pipes.’ A few years ago, they laid conduits under waters so people from island nations could make overseas calls.

That is also why they would ask people to turn off their phones when they get on airplanes. They finally got it working while moving using flight attendants on break, small flashlights, and quantum encryption.

Scientists are still working on calls dropping when people are on trampolines.
