What is a notable disadvantage of telephone communication?

The notable disadvantage of telephone communication is that it has limited mobility. While mobile phones have greatly enhanced the ability to communicate on the go, traditional landline telephones still necessitate a physical connection to a network, which restricts the user's ability to move freely while conversing. In contrast to more modern forms of communication that often allow for more portability, such as video calls on smartphones or text messaging, traditional telephone communication limits users to their current location when using a landline. This limitation can be particularly disadvantageous in scenarios where mobility is key, such as in business settings where quick, on-the-go communication is essential.
