What was one problem with using the telephone during World War I?
The wires weng prone to destruction during combat.
It was hard to hear what the person on the other end was saying.
O They were too heavy.
O There was always a busy signal.
The telephone was the preferred means of communication back then. It was lighter and more portable than radio, but the fact it used wires made it unreliable as the wires were always prone to destruction.
