The antonyms for the word "telephones" primarily refer to communication devices that do not require the use of wires, such as mobile phones or cellular devices. These devices allow users to communicate with one another without the impediment of wires, making them ideal for individuals on the go or for those who require access to communication while traveling. In contrast, traditional landline telephones, which are wired into a building's infrastructure or require a phone jack, are less mobile and less flexible in terms of communication options. While both types of telephones have their strengths and weaknesses, it's clear that mobile and wireless communication devices are becoming the preferred means of communication for many people in today's fast-paced world.
